When the nervous system in the baby matures. Development of the nervous system in a child1
The health of the child is the main thing for parents, but in order to take care of the health of your baby, you need to understand how the development of the whole organism as a whole and each system separately proceeds. In this article, we will look at the development of the child's nervous system, as well as possible good and bad sources of influence on it.
The body is a single whole, where organs and systems are interconnected and depend on each other. All activity of the body is regulated by the nervous system, especially its higher department - the cerebral cortex.
The development and activity of the brain, and the nervous system in general, depends on the conditions of life, on education - the decisive factor. Therefore, it is worth paying attention to this not only to you as educators, but also to grandparents.
The newborn is not adapted to independent existence. His movements are not yet formalized. Better movements developed hearing and vision. The newborn has only simple local reflexes, such as sucking, blinking. These are unconditioned (innate) reflexes.
Simultaneously with feeding and caring for the baby, the circumstances accompanying them are repeated many times: the voice of the mother, certain positions of the child, etc. Due to this, through unconditioned reflexes, new, response reactions of the child's body to various stimuli arise. New neural connections are formed, which are called conditioned reflexes.
In the future, the nervous system of the child is gradually improved. Verbal thinking arises in him and physical development progresses, connections are established between speech stimuli and muscle-motor reactions. Associated with this are the manifestations of the child's conscious, "actively imitative" actions. Such actions, representing the highest conditioned reflex activity, are gradually improved under the influence of the environment and education.
Some conditioned reflexes are strengthened and persist for many years, others fade away, slow down. New conditioned reflexes are also formed.
Conscious movements are of great importance in the life of a baby. Conscious movements are subject to the regulatory influence of the cerebral cortex. The development of coordination of movements is associated with the inhibition of unnecessary accompanying movements.
Thus, along with mastering the necessary movements, the development of inhibitory processes takes place, which are so important for the formation of higher nervous activity child.
Among the various constantly changing influences on the nervous system, there are those that are repeated with certain sequence(for example, regime moments). With the repeated repetition of one influence after another, a long chain of conditioned reflexes arises in the brain. A certain routine of activity, rest, sleep, and eating becomes habitual for the child. So he learns to obey.
Good condition the nervous system is the key to the health of the crumbs, his mental and moral development.
It is necessary to carefully protect the nervous system of children.
Proper development of the child's nervous system
What needs to be done so that the development of the baby's nervous system proceeds properly?
For this, it is necessary, firstly, to take care of the hygiene of their life. It is known, for example, beneficial effect of fresh air on brain function. In families where it is installed, an appropriate one is organized, the right child of this age is provided restful sleep(without
CHAPTER 10. DEVELOPMENT OF THE NERVOUS SYSTEM IN NEWBORN AND CHILDREN OF EARLY AGE. RESEARCH METHOD. SYNDROMES OF DEFEAT
In a newborn baby reflex acts are carried out at the level of the stem and subcortical parts of the brain. By the time of the birth of the child, the limbic system, the precentral region, especially field 4, which provides early phases motor reactions, occipital lobe and field 17. The temporal lobe is less mature (especially the temporo-parietal-occipital region), as well as the lower parietal and frontal regions. However, field 41 of the temporal lobe (the projection field of the auditory analyzer) by the time of birth is more differentiated than field 22 (projection-associative).
10.1. Development of motor functions
Motor development in the first year of life is a clinical reflection of the most complex and currently insufficiently studied processes. These include:
The action of genetic factors - the composition of expressed genes that regulate the development, maturation and functioning of the nervous system, changing in spatio-temporal dependence; neurochemical composition of the CNS, including the formation and maturation of mediator systems (the first mediators are found in the spinal cord from 10 weeks of gestation);
myelination process;
Macro- and microstructural formation of the motor analyzer (including muscles) in early ontogenesis.
First spontaneous movements embryos appear on the 5-6th week prenatal development. During this period, motor activity is carried out without the participation of the cerebral cortex; segmentation occurs spinal cord and differentiation of the musculoskeletal system. Education muscle tissue begins from the 4-6th week, when active proliferation occurs in the places of muscle laying with the appearance of primary muscle fibers. The emerging muscle fiber is already capable of spontaneous rhythmic activity. Simultaneously, the formation of neuromuscular
synapses under the influence of neuron induction (i.e., the axons of the emerging motor neurons of the spinal cord grow into the muscles). In addition, each axon branches many times, forming synaptic contacts with dozens of muscle fibers. Activation of muscle receptors affects the establishment of intracerebral connections of the embryo, which provides tonic excitation of brain structures.
In the human fetus, reflexes develop from local to generalized and then to specialized reflex acts. The first reflex movements appear at 7.5 weeks of gestation - trigeminal reflexes that occur with tactile irritation of the face area; at 8.5 weeks, lateral flexion of the neck is noted for the first time. On the 10th week, a reflex movement of the lips is observed (a sucking reflex is formed). Later, as the reflexogenic zones in the lips and oral mucosa mature, complex components are added in the form of opening and closing the mouth, swallowing, stretching and squeezing the lips (22 weeks), sucking movements (24 weeks).
tendon reflexes appear on the 18th-23rd week of intrauterine life, at the same age the grasping reaction is formed, by the 25th week all unconditioned reflexes evoked from the upper limbs are distinct. From the 10.5-11th week, reflexes from the lower extremities, primarily plantar, and a reaction of the Babinski reflex type (12.5 weeks). First irregular respiratory movements of the chest (according to the Cheyne-Stokes type), arising on the 18.5-23rd week, pass into spontaneous breathing by the 25th week.
In postnatal life, the improvement of the motor analyzer occurs at the micro level. After birth, the thickening of the cerebral cortex in areas 6, 6a and the formation of neuronal groups continue. The first networks formed from 3-4 neurons appear at 3-4 months; after 4 years, the thickness of the cortex and the size of neurons (except for Betz cells growing until puberty) stabilize. The number of fibers and their thickness increase significantly. The differentiation of muscle fibers is associated with the development of motor neurons of the spinal cord. Only after the appearance of heterogeneity in the population of motor neurons of the anterior horns of the spinal cord does the division of muscles into motor units occur. Later, at the age of 1 to 2 years, not individual muscle fibers develop, but “superstructures” - motor units consisting of muscles and nerve fibers, and changes in the muscles are primarily associated with the development of the corresponding motor neurons.
After the birth of a child, as the controlling parts of the CNS mature, so do its pathways, in particular, myelination of peripheral nerves occurs. At the age of 1 to 3 months, the development of the frontal and temporal regions brain. The cerebellar cortex is still poorly developed, but the subcortical ganglia are clearly differentiated. Up to the midbrain region, myelination of fibers is well expressed; in the cerebral hemispheres, only sensory fibers are fully myelinated. From 6 to 9 months, long associative fibers are most intensively myelinated, the spinal cord is completely myelinated. By the age of 1 year, myelination processes covered long and short associative pathways of the temporal and frontal lobes and the spinal cord along its entire length.
There are two periods of intense myelination: the first of them lasts from 9-10 months of intrauterine life to 3 months of postnatal life, then from 3 to 8 months the rate of myelination slows down, and from 8 months the second period of active myelination begins, which lasts until the child learns to walk (t .e. on average up to 1 g 2 months). With age, both the number of myelinated fibers and their content in individual peripheral nerve bundles change. These processes, which are most intense in the first 2 years of life, are mostly completed by the age of 5.
An increase in the speed of impulse conduction along the nerves precedes the emergence of new motor skills. So, in the ulnar nerve, the peak of the increase in the impulse conduction velocity (SPI) falls on the 2nd month of life, when the child can briefly clasp his hands while lying on his back, and on the 3rd-4th month, when hypertonicity in the hands is replaced by hypotension, the volume of active movements increases (holds objects in the hand, brings them to the mouth, clings to clothes, plays with toys). In the tibial nerve, the greatest increase in SPI appears first at 3 months and precedes the disappearance of physiological hypertension in the lower extremities, which coincides with the disappearance of automatic gait and positive support reaction. For the ulnar nerve, the next rise in SPI is noted at 7 months with the onset of a jump preparation reaction and the extinction of the grasping reflex; in addition, there is an opposition of the thumb, an active force appears in the hands: the child shakes the bed and breaks toys. For the femoral nerve, the next increase in the conduction velocity corresponds to 10 months, for the ulnar nerve - 12 months.
At this age, free standing and walking appear, hands are freed: the child waves them, throws toys, claps his hands. Thus, there is a correlation between the increase in SPI in the fibers of the peripheral nerve and the development of the child's motor skills.
10.1.1. Reflexes of newborns
Reflexes of newborns - this is an involuntary muscular reaction to a sensitive stimulus, they are also called: primitive, unconditioned, innate reflexes.
Unconditioned reflexes according to the level at which they close can be:
1) segmental stem (Babkina, sucking, proboscis, search);
2) segmental spinal (grasping, crawling, support and automatic gait, Galant, Perez, Moro, etc.);
3) postural suprasegmental - levels of the brainstem and spinal cord (asymmetric and symmetrical tonic neck reflexes, labyrinth tonic reflex);
4) posotonic suprasegmental - the level of the midbrain (straightening reflexes from the head to the neck, from the trunk to the head, from the head to the trunk, start reflex, balance reaction).
The presence and severity of the reflex is an important indicator of psychomotor development. Many neonatal reflexes disappear as the child develops, but some of them can be found in adulthood, but they do not have topical significance.
The absence of reflexes or pathological reflexes in a child, a delay in the reduction of reflexes characteristic of more early age, or their appearance in an older child or adult indicates damage to the central nervous system.
Unconditioned reflexes are examined in the position on the back, stomach, vertically; it can reveal:
The presence or absence, inhibition or strengthening of the reflex;
The time of appearance from the moment of irritation (latent period of the reflex);
The severity of the reflex;
The speed of its extinction.
Unconditioned reflexes are influenced by factors such as the type of higher nervous activity, the time of day, and the general condition of the child.
The most constant unconditioned reflexes In the supine position:
search reflex- the child lies on his back, when stroking the corner of the mouth it lowers, and the head turns in the direction of irritation; options: mouth opening, lowering mandible; the reflex is especially well expressed before feeding;
defensive reaction- pain stimulation of the same area causes the head to turn in the opposite direction;
proboscis reflex- the child lies on his back, easy fast a blow to the lips causes a contraction of the circular muscle of the mouth, while the lips are pulled out with a "proboscis";
sucking reflex- active sucking of the nipple inserted into the mouth;
palmar-mouth reflex (Babkina)- pressure on the thenar area of the palm causes the opening of the mouth, tilt of the head, flexion of the shoulders and forearms;
grasping reflex occurs when a finger is inserted into the child's open palm, while his hand covers the finger. An attempt to release the finger leads to an increase in grasping and suspension. In newborns, the grasp reflex is so strong that they can be lifted off the changing table if both hands are involved. The lower grasp reflex (Wercombe) can be induced by pressing on the pads under the toes at the base of the foot;
Robinson reflex- when you try to release the finger, suspension occurs; this is a logical continuation of the grasping reflex;
lower grasp reflex- plantar flexion of the fingers in response to touching the base of II-III toes;
Babinski reflex- with stroke stimulation of the sole of the foot, a fan-shaped divergence and extension of the fingers occur;
Moro reflex: I phase - breeding of hands, sometimes so pronounced that it occurs with a turn around the axis; Phase II - return to the starting position after a few seconds. This reflex is observed when the child is suddenly shaken, loud sound; the spontaneous Moro reflex often causes a baby to fall off the changing table;
defensive reflex- when the sole is injected, the leg is triple flexed;
cross reflex extensors- a prick of the sole, fixed in the extended position of the leg, causes straightening and slight adduction of the other leg;
start reflex(extension of arms and legs in response to a loud sound).
Upright (normally, when the child is vertically suspended by the armpits, bending occurs in all joints of the legs):
support reflex- in the presence of a solid support under the feet, the body straightens and rests on a full foot;
automatic gait occurs if the child is slightly tilted forward;
rotational reflex- when rotating in vertical suspension by the armpits, the head turns in the direction of rotation; if at the same time the head is fixed by the doctor, then only the eyes turn; after the appearance of fixation (by the end of the neonatal period), the turn of the eyes is accompanied by nystagmus - assessment of the vestibular response.
In the prone position:
defensive reflex- when laying the child on the stomach, the head turns to the side;
crawl reflex (Bauer)- light pushing of the hand to the feet causes repulsion from it and movements resembling crawling;
Talent reflex- when the skin of the back near the spine is irritated, the body bends in an arc open towards the stimulus; the head turns in the same direction;
Perez reflex- when you run your finger along the spinous processes of the spine from the coccyx to the neck, a pain reaction, a cry occur.
Reflexes that persist in adults:
Corneal reflex (squinting the eye in response to touch or sudden exposure to bright light);
Sneezing reflex (sneezing when the nasal mucosa is irritated);
Gag reflex (vomiting when irritating the posterior pharyngeal wall or the root of the tongue);
Yawning reflex (yawning with a lack of oxygen);
Cough reflex.
Grade motor development child of any age is carried out at the moment of maximum comfort (warmth, satiety, peace). It should be borne in mind that the development of the child occurs craniocaudally. This means that the upper parts of the body develop before the lower ones (for example,
manipulation precedes the ability to sit, which, in turn, precedes the appearance of walking). In the same direction, muscle tone also decreases - from physiological hypertonicity to hypotension by 5 months of age.
The components of the assessment of motor functions are:
muscle tone and postural reflexes(proprioceptive reflexes of the muscular-articular apparatus). There is a close relationship between muscle tone and postural reflexes: muscle tone affects posture in sleep and in a state of calm wakefulness, and posture, in turn, affects tone. Tone options: normal, high, low, dystonic;
tendon reflexes. Options: absence or decrease, increase, asymmetry, clonus;
volume of passive and active movements;
unconditioned reflexes;
pathological movements: tremor, hyperkinesis, convulsions.
At the same time, attention should be paid to the general condition of the child (somatic and social), the characteristics of his emotional background, the function of analyzers (especially visual and auditory) and the ability to communicate.
10.1.2. Development of motor skills in the first year of life
Newborn. Muscle tone. Normally, the tone in the flexors predominates (flexor hypertension), and the tone in the arms is higher than in the legs. As a result of this, a “fetal position” arises: the arms are bent at all joints, brought to the body, pressed to the chest, the hands are clenched into fists, thumbs squeezed by the rest; the legs are bent in all joints, slightly abducted at the hips, in the feet - dorsiflexion, the spine is curved. Muscle tone is increased symmetrically. To determine the degree of flexor hypertension, there are the following tests:
traction test- the child lies on his back, the researcher takes him by the wrists and pulls him towards himself, trying to seat him. At the same time, the arms are slightly unbent in the elbow joints, then the extension stops, and the child is pulled up to the hands. With an excessive increase in flexor tone, there is no extension phase, and the body immediately moves behind the hands, with insufficiency, the extension volume increases or there is no sipping behind the hands;
With normal muscle tone in a horizontal hanging posture behind the armpits, face down, the head is in line with the body. In this case, the arms are bent, and the legs are extended. With a decrease in muscle tone, the head and legs passively hang down, with an increase, a pronounced bending of the arms and, to a lesser extent, legs occurs. With the predominance of extensor tone, the head is thrown back;
labyrinthine tonic reflex (LTR) occurs when the position of the head in space changes as a result of stimulation of the labyrinths. This increases the tone in the extensors in the supine position and in the flexors in the prone position;
symmetrical neck tonic reflex (SNTR)- in the position on the back with a passive tilt of the head, the tone of the flexors in the arms and extensors in the legs increases, with the extension of the head - the opposite reaction;
asymmetric neck tonic reflex (ASTTR), Magnus-Klein reflex occurs when the head of a child lying on his back is turned to the side. At the same time, in the hand, to which the child's face is turned, the extensor tone increases, as a result of which it unbends and is retracted from the body, the hand opens. At the same time, the opposite arm is bent and her hand is clenched into a fist (swordsman's pose). As the head turns, the position changes accordingly.
Volume of passive and active movements
Flexor hypertension overcome, but limits the amount of passive movement in the joints. It is impossible to completely unbend the child's arms in the elbow joints, raise the arms above the horizontal level, spread the hips without causing pain.
Spontaneous (active) movements: periodic flexion and extension of the legs, cross, repulsion from the support in the position on the stomach and back. Movements in the hands are made in the elbow and wrist joints (hands clenched into fists move at chest level). Movements are accompanied by an athetoid component (a consequence of the immaturity of the striatum).
Tendon reflexes: the newborn can only cause knee jerks, which are usually elevated.
Unconditioned reflexes: all reflexes of newborns are caused, they are moderately expressed, slowly are exhausted.
Postural reactions: the newborn lies on his stomach, his head is turned to the side (protective reflex), the limbs are bent in
all joints and brought to the body (labyrinth tonic reflex). Direction of development: exercises for holding the head vertically, leaning on the hands.
Walking Ability: a newborn and a child of 1–2 months of age have a primitive reaction of support and automatic gait, which fades by 2–4 months of age.
Grasping and manipulation: in a newborn and a child of 1 month, the hands are clenched into a fist, he cannot open the hand on his own, a grasping reflex is caused.
Social contacts: The first impressions of the newborn about the world around are based on skin sensations: warm, cold, soft, hard. The child calms down when he is picked up, fed.
Child aged 1-3 months. When evaluating the motor function, in addition to those listed earlier (muscle tone, postural reflexes, the volume of spontaneous movements, tendon reflexes, unconditioned reflexes), the initial elements of voluntary movements and coordination begin to be taken into account.
Skills:
Development of analyzer functions: fixation, tracking (visual), sound localization in space (auditory);
Integration of analyzers: sucking fingers (sucking reflex + influence of the kinesthetic analyzer), examining one's own hand (visual-kinesthetic analyzer);
The appearance of more expressive facial expressions, a smile, a complex of revival.
Muscle tone. Flexor hypertension gradually decreases. At the same time, the influence of postural reflexes increases - ASTR, LTE are more pronounced. The value of postural reflexes is to create a static posture, while the muscles are “trained” to actively (and not reflexively) hold this posture (for example, the upper and lower Landau reflex). As the muscles are trained, the reflex gradually fades away, since the processes of central (voluntary) regulation of the posture are turned on. By the end of the period, the flexion posture becomes less pronounced. During the traction test, the extension angle increases. By the end of 3 months, postural reflexes weaken, and they are replaced by straightening reflexes of the body:
labyrinth straightening (adjusting) reflex on the head- in the position on the stomach, the head of the child is located on the middle
line, a tonic contraction of the neck muscles occurs, the head rises and is held. Initially, this reflex ends with the fall of the head and turning it to the side (the influence of a protective reflex). Gradually, the head can be in a raised position for longer and longer, while the legs are tense at first, but over time they begin to actively move; arms are more and more unbent at the elbow joints. A labyrinthic installation reflex is formed in a vertical position (holding the head vertically);
straightening reflex from trunk to head- when the feet touch the support, the body straightens and the head rises;
cervical rectifying reaction - with a passive or active turn of the head, the body turns.
Unconditioned reflexes still well expressed; the exception is the reflexes of support and automatic gait, which gradually begin to fade. At 1.5-2 months, the child in an upright position, placed on a hard surface, rests on the outer edges of the feet, does not make step movements when leaning forward.
By the end of 3 months, all reflexes weaken, which is expressed in their inconstancy, lengthening of the latent period, rapid exhaustion, and fragmentation. The Robinson reflex disappears. Moro's reflexes, sucking and withdrawal reflexes are still well evoked.
Combined reflex reactions appear - a sucking reflex at the sight of the breast (kinesthetic food reaction).
The range of motion increases. The athetoid component disappears, the number of active movements increases. Arises recovery complex. The first becomes possible purposeful movement: straightening the arms up, bringing the hands to the face, sucking the fingers, rubbing the eyes and nose. At the 3rd month, the child begins to look at his hands, reach out with his hands to the object - visual blink reflex. Due to the weakening of the synergy of the flexors, flexion occurs in the elbow joints without bending the fingers, the ability to hold an enclosed object in the hand.
Tendon reflexes: in addition to the knee, Achilles, bicipital are called. Abdominal reflexes appear.
Postural reactions: during the 1st month, the child raises its head for a short time, then “drops” it. Arms bent under the chest (labyrinth straightening reflex on the head, tonic contraction of the neck muscles ends with the head falling and turning it to the side -
element of a protective reflex). Direction of development: exercise to increase the time of holding the head, extension of the arms in the elbow joint, opening of the hand. At the 2nd month, the child can hold his head at an angle of 45? for some time. to the surface, while the head is still swaying uncertainly. The angle of extension in the elbow joints increases. At the 3rd month, the child confidently holds his head, lying on his stomach. Forearm support. The pelvis is down.
Walking Ability: a child of 3-5 months holds his head well in an upright position, but if you try to put him, he draws his legs and hangs on the hands of an adult (physiological astasia-abasia).
Grasping and manipulation: on the 2nd month, the brushes are slightly ajar. At the 3rd month, a small light rattle can be put into the child's hand, he grabs it and holds it in his hand, but he himself is not yet able to open the brush and release the toy. Therefore, after playing for some time and listening with interest to the sounds of the rattle that are heard when it is shaken, the child begins to cry: he gets tired of holding the object in his hand, but cannot voluntarily release it.
Social contacts: at the 2nd month, a smile appears, which the child addresses to all living beings (as opposed to inanimate ones).
Child aged 3-6 months. At this stage, the assessment of motor functions consists of the previously listed components (muscle tone, range of motion, tendon reflexes, unconditioned reflexes, voluntary movements, their coordination) and newly emerged general motor skills, in particular manipulations (hand movements).
Skills:
Increase in the period of wakefulness;
Interest in toys, looking, grasping, bringing to the mouth;
The development of facial expressions;
The appearance of cooing;
Communication with an adult: the orienting reaction turns into a complex of revival or a reaction of fear, a reaction to the departure of an adult;
Further integration (sensory-motor behavior);
Auditory reactions;
Hearing-motor reactions (turning the head towards the call);
Visual-tactile-kinesthetic (examining one's own hands is replaced by examining toys, objects);
Visual-tactile-motor (grasping objects);
Hand-eye coordination - the ability to control with a glance the movements of a hand reaching for a closely located object (feeling one's hands, rubbing, joining hands, touching one's head, while sucking, holding a breast, a bottle);
The reaction of active touch - feeling the object with your feet and grasping with their help, stretching your arms in the direction of the object, feeling; this reaction disappears when the object capture function appears;
Skin concentration reaction;
Visual localization of an object in space based on a visual-tactile reflex;
Increasing visual acuity; the child can distinguish small objects against a solid background (for example, buttons on clothes of the same color).
Muscle tone. There is a synchronization of the tone of the flexors and extensors. Now the posture is determined by a group of reflexes that straighten the body and voluntary motor activity. In a dream, the hand is open; ASHTR, SSTR, LTR have faded. The tone is symmetrical. Physiological hypertension is replaced by normotonia.
There is further formation rectifying reflexes of the body. In the position on the stomach, a steady hold of the raised head is noted, reliance on a slightly extended arm, later - reliance on the outstretched arm. The upper Landau reflex appears in the position on the stomach ("swimmer's position", i.e. raising the head, shoulders and torso in the position on the stomach with straightened arms). Head control in a vertical position is stable, sufficient in the supine position. There is a straightening reflex from the body to the body, i.e. the ability to rotate the shoulder girdle relative to the pelvic.
tendon reflexes all are called.
Developing motor skills following.
Attempts to pull the body to the outstretched arms.
Ability to sit with support.
The appearance of a "bridge" - arching of the spine based on the buttocks (feet) and head while tracking the object. In the future, this movement is transformed into an element of a turn on the stomach - a “block” turn.
Turn from back to stomach; at the same time, the child can rest with his hands, raising his shoulders and head and looking around in search of objects.
Objects are captured by the palm (squeezing the object in the palm with the help of the flexor muscles of the hand). There is no opposition of the thumb yet.
The capture of an object is accompanied by a lot of unnecessary movements (both hands, mouth, legs move at the same time), there is still no clear coordination.
Gradually, the number of extra movements decreases. Grasping an attractive object with both hands appears.
The number of movements in the hands increases: lifting up, to the sides, clutching together, feeling, putting into the mouth.
Movements in large joints, fine motor skills are not developed.
Ability to sit independently (without support) for a few seconds/minutes.
Unconditioned reflexes fade away, except for the sucking and withdrawal reflexes. Elements of the Moro reflex are preserved. The appearance of a parachute reflex (in the position of hanging by the armpits horizontally face down, as in a fall, the arms are unbent and the fingers spread apart - as if in an attempt to protect themselves from a fall).
Postural reactions: at the 4th month, the child's head is stably raised; support on an outstretched arm. In the future, this posture becomes more complicated: the head, the shoulder girdle are raised, the arms are straightened and stretched forward, the legs are straight (swimmer's position, upper Landau reflection). Lifting up the legs (lower Landau reflex), the baby can rock on the stomach and turn around it. At the 5th month, the ability to turn from the position described above onto the back appears. First, a turn from the stomach to the back occurs by chance when the arm is thrown far forward and the balance on the stomach is disturbed. Direction of development: exercises for the purposefulness of turns. At the 6th month, the head and shoulder girdle were raised above the horizontal surface at an angle of 80–90°, the arms were straightened at the elbow joints, resting on fully open hands. Such a posture is already so stable that the child can follow the object of interest by turning his head, and also transfer the body weight to one hand, and with the other hand try to reach for the object and grab it.
Ability to sit - keeping the body in a static state - is a dynamic function and requires the work of many muscles and precise coordination. This posture allows you to free your hands for fine motor actions. To learn to sit, you need to master three fundamental functions: keep your head upright in any position of the body, bend your hips, and actively rotate your torso. At the 4-5th month, when sipping on the arms, the child, as it were, “sits down”: bends his head, arms and legs. At the 6th month, the child can be planted, while for some time he will hold his head and torso vertically.
Walking Ability: at the 5-6th month, the ability to stand with the support of an adult, leaning on a full foot, gradually appears. At the same time, the legs are straightened. Quite often, the hip joints remain slightly bent in an upright position, as a result of which the child does not stand on a full foot, but on his toes. This isolated phenomenon is not a manifestation of spastic hypertonicity, but a normal stage in the formation of gait. A "jump phase" appears. The child begins to bounce when put on his feet: the adult holds the child under the armpits, he crouches and pushes, straightening the hips, knees and ankle joints. This causes a lot of positive emotions and, as a rule, is accompanied by loud laughter.
Grasping and manipulation: at the 4th month, the range of motion in the hand increases significantly: the child brings his hands to his face, examines them, brings them and puts them in his mouth, rubs his hand in hand, touches the other with one hand. He may accidentally grab a toy that is within reach and also bring it to his face, to his mouth. Thus, he explores the toy - with his eyes, hands and mouth. At the 5th month, the child can voluntarily take an object lying in the field of vision. At the same time, he stretches out both hands and touches him.
Social contacts: from 3 months the child begins to laugh in response to communication with him, a complex of revival and cries of joy appear (until this time, a cry occurs only with unpleasant sensations).
Child aged 6-9 months. In this age period, the following functions are noted:
Development of integrative and sensory-situational connections;
Active cognitive activity based on visual-motor behavior;
Chain motor associative reflex - listening, observing one's own manipulations;
Development of emotions;
Games;
Variety of facial movements. Muscle tone - fine. Tendon reflexes are caused by everything. Motor skills:
Development of arbitrary purposeful movements;
Development of the rectifying reflex of the body;
Turns from stomach to back and from back to stomach;
Reliance on one hand;
Synchronization of the work of antagonist muscles;
Stable independent sitting for a long time;
Chain symmetrical reflex in the position on the stomach (the basis of crawling);
Crawling back, in a circle, with the help of pull-ups on the hands (legs do not participate in crawling);
Crawling on all fours with lifting the body above the support;
Attempts to take a vertical position - when sipping on the hands from a supine position, he immediately rises to straightened legs;
Attempts to get up, holding hands on a support;
The beginning of walking along the support (furniture);
Attempts to sit down independently from an upright position;
Attempts to walk while holding the hand of an adult;
Plays with toys, II and III fingers participate in manipulations. Coordination: coordinated clear hand movements; at
manipulations in the sitting position, a lot of unnecessary movements, instability (i.e. arbitrary actions with objects in the sitting position are a load test, as a result of which the position is not maintained and the child falls).
Unconditioned reflexes extinguished, except for the suckling.
Postural reactions: at the 7th month, the child is able to turn from his back to his stomach; for the first time, on the basis of the rectifying reflex of the body, the ability to sit down independently is realized. At the 8th month, turns are improved, and the phase of crawling on all fours develops. At the 9th month, the ability to purposefully crawl with support on the hands appears; leaning on the forearms, the child pulls the entire body.
Ability to sit: at the 7th month, the child lying on his back assumes a “sitting” position, bending his legs at the hip and knee joints. In this position, the child can play with his legs and pull them into his mouth. At 8 months, a seated baby can sit on its own for several seconds, and then “fall over” on its side, leaning with one hand on the surface to protect itself from falling. At the 9th month, the child sits for a longer time on his own with a “round back” (lumbar lordosis has not yet been formed), and when tired, he leans back.
Walking Ability: at the 7-8th month, a reaction of support on the hands appears if the child is sharply tilted forward. At the 9th month, a child placed on the surface and supported by the arms stands independently for several minutes.
Grasping and manipulation: on the 6-8th month, the accuracy of capturing the object improves. The child takes it with the entire surface of the palm. Can transfer an item from one hand to the other. At the 9th month, he voluntarily releases the toy from his hands, it falls, and the child carefully follows the trajectory of its fall. He likes it when an adult picks up a toy and gives it to a child. Releases the toy again and laughs. Such an activity, according to an adult, is a stupid and meaningless game, in fact it is a complex training of hand-eye coordination and a difficult social act- playing with an adult.
Child aged 9-12 months. This age period includes:
Development and complication of emotions; the revitalization complex fades away;
Various facial expressions;
Sensory speech, understanding of simple commands;
The appearance of simple words;
Story games.
Muscle tone, tendon reflexes remain unchanged in comparison with the previous stage and throughout the rest of life.
Unconditioned reflexes everything faded away, the sucking reflex fades.
Motor skills:
Improvement of complex chain reflexes of verticalization and voluntary movements;
Ability to stand at a support; attempts to stand without support, on their own;
The appearance of several independent steps, the further development of walking;
Repeated actions with objects (“memorization” of motor patterns), which can be considered as the first step towards the formation of complex automated movements;
Purposeful actions with objects (inserting, putting on).
The formation of the gait children are very variable and individual. Manifestations of character and personality are clearly demonstrated in attempts to stand, walk and play with toys. In most children, by the beginning of walking, the Babinski reflex and the lower grasping reflex disappear.
Coordination: immaturity of coordination when taking an upright position, leading to falls.
Perfection fine motor skills: grasping small objects with two fingers; there is opposition between the thumb and little finger.
In the 1st year of a child's life, the main directions of motor development are distinguished: postural reactions, elementary movements, crawling on all fours, the ability to stand, walk, sit, grasping abilities, perception, social behavior, making sounds, understanding speech. Thus, there are several stages in development.
Postural reactions: at the 10th month, in the position on the stomach with a raised head and support on the hands, the child can simultaneously raise the pelvis. Thus, it rests only on the palms and feet and sways back and forth. At the 11th month, he begins to crawl with support on his hands and feet. Further, the child learns to crawl in a coordinated way, i.e. taking out alternately right hand- left leg and left hand - right leg. At the 12th month, crawling on all fours becomes more and more rhythmic, smooth, and fast. From this moment, the child begins to actively explore and explore his home. Crawling on all fours is a primitive form of movement, atypical for adults, but at this stage the muscles are prepared for the following stages of motor development: muscle strength increases, coordination and balance are trained.
The ability to sit is formed individually from 6 to 10 months. This coincides with the development of the pose on all fours (support on the palms and feet), from which the child easily sits down, turning the pelvis relative to the body ( rectifying reflex from the pelvic girdle to the torso). The child sits independently, stably with a straight back and legs straightened at the knee joints. In this position, the child can play for a long time without losing balance. Next, seat
becomes so stable that the child can perform extremely complex actions while sitting, requiring excellent coordination: for example, holding a spoon and eating with it, holding a cup with both hands and drinking from it, playing with small objects, etc.
Walking Ability: at the 10th month, the child crawls to the furniture and, holding on to it, gets up on its own. At the 11th month, the child can walk along the furniture, holding on to it. At the 12th month, it becomes possible to walk, holding on with one hand, and, finally, to take several independent steps. In the future, coordination and strength of the muscles involved in walking develop, and walking itself improves more and more, becoming faster, more purposeful.
Grasping and manipulation: on the 10th month, a “tweezer-like grip” appears with opposition of the thumb. The child can take small items, while he pulls out a large and index fingers and holds the object with them, like tweezers. At the 11th month, a “pincer grip” appears: the thumb and forefinger form a “claw” during grip. The difference between the pincer grip and the claw grip is that the former has straight fingers while the latter has bent fingers. At the 12th month, a child can accurately put an object into a large dish or an adult's hand.
Social contacts: by the 6th month, the child distinguishes "friends" from "strangers". At 8 months, the child begins to be afraid of strangers. He no longer allows everyone to take him in his arms, touch him, turns away from strangers. At 9 months, the child begins to play hide-and-seek - peek-a-boo.
10.2. Examination of a child from the neonatal period to six months
When examining a newborn baby, his gestational age should be taken into account, because even a slight immaturity or prematurity of less than 37 weeks can significantly affect the nature of spontaneous movements (movements are slow, generalized with tremor).
Muscle tone is changed, and the degree of hypotension is directly proportional to the degree of maturity, usually in the direction of its decrease. A full-term baby has a pronounced flexor posture (reminiscent of an embryonic one), and a premature baby has an extensor posture. A full-term baby and a child with prematurity of the 1st degree hold the head for a few seconds when pulling the handles, children with prematurity
a deeper degree and children with damaged central nervous system do not hold their heads. It is important to determine the severity of physiological reflexes in the neonatal period, especially grasping, suspension, as well as reflexes that provide sucking, swallowing. When examining the function of the cranial nerves, it is necessary to pay attention to the size of the pupils and their reaction to light, the symmetry of the face, and the position of the head. Most healthy newborns fix their gaze on the 2-3rd day after birth and try to follow the object. Symptoms such as Graefe's symptom, nystagmus in the extreme leads are physiological and are due to the immaturity of the posterior longitudinal bundle.
Severe edema in a child can cause depression of all neurological functions, but if it does not decrease and is combined with liver enlargement, a congenital form of hepatocerebral dystrophy (hepatolenticular degeneration) or lysosomal disease should be suspected.
Specific (pathognomonic) neurological symptoms characteristic of dysfunction of a particular area of the CNS are absent until 6 months of age. The main neurological symptoms are usually impaired muscle tone with or without motor deficits; communication disorders, which are determined by the ability to fix the gaze, follow objects, single out acquaintances, etc., and reactions to various stimuli: the more clearly visual control is expressed in a child, the more perfect his nervous system. Great importance given to the presence of paroxysmal epileptic phenomena or their absence.
The exact description of all paroxysmal phenomena is the more difficult, the smaller the age of the child. Convulsions that occur in this age period are often polymorphic.
The combination of altered muscle tone with movement disorders (hemiplegia, paraplegia, tetraplegia) indicates a gross focal lesion brain substances. In about 30% of cases of hypotension of central origin, no cause can be found.
History and somatic symptoms are of particular importance in newborns and children under 4 months of age due to the paucity of neurological examination data. For example, respiratory disorders at this age can often be the result of CNS damage and occur with
congenital forms of myatonia and spinal amyotrophy. Apnea and dysrhythmia may be due to abnormalities of the brainstem or cerebellum, Pierre Robin's anomaly, and metabolic disorders.
10.3. Examination of a child aged 6 months to 1 year
In children from 6 months to 1 year, both acute neurological disorders with a catastrophic course and slowly progressive ones often occur, so the doctor must immediately outline the range of diseases that can lead to these conditions.
The appearance of febrile and unprovoked convulsions such as infantile spasms is characteristic. Movement disorders are manifested by a change in muscle tone and its asymmetry. In this age period, such congenital diseases, How spinal amyotrophy and myopathy. The doctor must remember that the asymmetry of the muscle tone of a child of this age may be due to the position of the head in relation to the body. The lag in psychomotor development may be the result of metabolic and degenerative diseases. Emotional disorders - poor facial expressions, lack of a smile and loud laughter, as well as pre-speech development disorders (babbling formation) are caused by hearing impairment, brain underdevelopment, autism, degenerative diseases of the nervous system, and when combined with skin manifestations - tuberous sclerosis, for which motor stereotypes and convulsions are also characteristic.
10.4. Examination of a child after the 1st year of life
The progressive maturation of the central nervous system causes the appearance of specific neurological symptoms indicating a focal lesion, and it is possible to determine the dysfunction of a particular area of the central or peripheral nervous system.
The most common reasons for visiting a doctor are a delay in the development of gait, its violation (ataxia, spastic paraplegia, hemiplegia, diffuse hypotension), walking regression, hyperkinesis.
Combination of neurological symptoms with extraneural (somatic) ones, their slow progression, development of skull and face dysmorphias, lag in mental development and violation of emotions should prompt the doctor to the idea of the presence of metabolic diseases - mucopolysaccharidosis and mucolipidosis.
The second most common reason for treatment is mental retardation. A gross lag is observed in 4 out of 1000 children, and in 10-15% this delay is the cause of learning difficulties. It is important to diagnose syndromal forms, in which oligophrenia is only a symptom of general underdevelopment of the brain against the background of dysmorphias and multiple developmental anomalies. Impairment of intelligence may be due to microcephaly, the cause of developmental delay can also be progressive hydrocephalus.
Cognitive disorders in combination with chronic and progressive neurological symptoms in the form of ataxia, spasticity or hypotension with high reflexes should prompt the doctor to think about the onset of mitochondrial disease, subacute panencephalitis, HIV encephalitis (in combination with polyneuropathy), Creutzfeldt-Jakob disease. Impairment of emotions and behavior, combined with cognitive deficits, suggests the presence of Rett syndrome, Santavuori's disease.
Sensorineural disorders (visual, oculomotor, auditory) are very widely represented in childhood. There are many reasons for their appearance. They may be congenital, acquired, chronic or developing, isolated or associated with other neurological symptoms. They can be caused by embryofetal brain damage, an anomaly in the development of the eye or ear, or these are the consequences of previous meningitis, encephalitis, tumors, metabolic or degenerative diseases.
Oculomotor disorders in some cases are the result of damage to the oculomotor nerves, including the congenital Graefe-Mobius anomaly.
From 2 years oldthe frequency of occurrence of febrile convulsions sharply increases, which should completely disappear by the age of 5. After 5 years, epileptic encephalopathy debuts - Lennox-Gastaut syndrome and most childhood idiopathic forms of epilepsy. Acute onset neurological disorders with impaired consciousness, pyramidal and extrapyramidal neurological symptoms, debuting against the background of febrile condition, especially with concomitant purulent diseases in the face (sinusitis), should raise suspicion of bacterial meningitis, brain abscess. These conditions require urgent diagnosis and specific treatment.
At a younger age malignant tumors also develop, most often of the brainstem, cerebellum and its worm, the symptoms of which can develop acutely, subacutely, often after children stay in southern latitudes, and manifest not only headache, but also dizziness, ataxia due to occlusion of the CSF pathways.
It is not uncommon for blood diseases, in particular lymphomas, to debut with acute neurological symptoms in the form of opsomyoclonus, transverse myelitis.
In children after 5 years most common cause going to the doctor is a headache. If she wears a special stubborn chronic, accompanied by dizziness, neurological symptoms, especially cerebellar disorders (static and locomotor ataxia, intentional tremor), it is necessary first of all to exclude a brain tumor, mainly a tumor of the posterior cranial fossa. These complaints and the listed symptoms are an indication for CT and MRI studies of the brain.
Slowly progressive development of spastic paraplegia, sensory disorders in the presence of asymmetry and dysmorphias of the trunk may raise the suspicion of syringomyelia, and the acute development of symptoms - hemorrhagic myelopathy. Acute peripheral paralysis with radicular pain, sensory disturbance and pelvic disorders are characteristic of polyradiculoneuritis.
Delays in psychomotor development, especially in combination with the breakdown of intellectual functions and progressive neurological symptoms, occur against the background of metabolic and neurodegenerative diseases at any age and have different rates of development, but in this age period it is very important to know that impairment of intellectual functions and motor skills and speech may be a consequence of epileptiform encephalopathy.
Progressive neuromuscular diseases make their debut in different time with gait disorders, muscle atrophy and changes in the shape of the feet and legs.
In older children, more often in girls, there may be episodic attacks of dizziness, ataxia with sudden visual impairment and the appearance of seizures, which at first
difficult to distinguish from epileptic. These symptoms are accompanied by changes in the affective sphere of the child, and observations of family members and an assessment of their psychological profile make it possible to reject the organic nature of the disease, although in isolated cases additional research methods are required.
In this period, various forms of epilepsy, infections and autoimmune diseases of the nervous system often debut, less often - neurometabolic. Circulatory disorders may also occur.
10.5. Formation of pathological postural activity and movement disorders in early organic brain damage
Violation of the child's motor development is one of the most common consequences of damage to the nervous system in the ante- and perinatal period. The delay in the reduction of unconditioned reflexes leads to the formation of pathological postures and attitudes, inhibits and distorts further motor development.
As a result, all this is expressed in a violation of the motor function - the appearance of a complex of symptoms, which by the 1st year is clearly formed into a child's syndrome. cerebral palsy. Components of the clinical picture:
Damage to motor control systems;
Delayed reduction of primitive postural reflexes;
Delay in general development, including mental;
Violation of motor development, sharply enhanced tonic labyrinth reflexes, leading to the appearance of reflex-protective positions, in which the “embryonic” posture is maintained, a delay in the development of extensor movements, chain symmetrical and adjusting reflexes of the body;
The nervous system in a child, especially under 5 years old, is still too weak. Therefore, do not be surprised if the baby begins to act up for no apparent reason, startle at the appearance of any source of noise, his chin is shaking. And it turns out to be very difficult to calm him down. What could be the reason for such a reaction? How to treat and strengthen the child's nervous system?
In children and adults, the characteristics of the nervous and cardiovascular systems are completely different. The regulation of nerve pathways up to 3-5 years is still immature, weak and imperfect, but it is an anatomical and physiological feature of his body, which explains why they quickly get bored even with their favorite pastime, game, it is extremely difficult for them to sit in one place during the same monotonous classes. This is how the neuropsychic development of children differs.
From about 6 months, the child already becomes a person, before that, children basically still identify themselves with their mother. Communicating with the baby and raising him, parents must take into account the characteristics and type of the nervous system of a small person and, of course, the anatomical and physiological characteristics of their child.
Sanguine children are always on the move, they are full of strength and energy, cheerful and easily switch from any activity they are currently engaged in to another. Phlegmatic people are distinguished by efficiency and calmness, but they are too slow. Cholerics are energetic, but it is difficult for them to control themselves. They are also difficult to calm down. Melancholic children are shy and modest, offended by even the slightest criticism from the outside.
The nervous system of a child always begins its development long before his birth. Even at the 5th month of his intrauterine life, it is strengthened due to enveloping the nerve fiber with myelin (another name is myelination).
myelination nerve fibers different parts of the brain occurs in different periods in a regular order and serves as an indicator of the beginning of the functioning of the nerve fiber. At the time of birth, the myelination of fibers is not yet complete, because not all parts of the brain can still fully function. Gradually, the process of development takes place in absolutely every department, thanks to which connections are established between different centers. Similarly, the formation and regulation of children's intelligence. The kid begins to recognize the faces and objects around him, understands their purpose, although the immaturity of the system is still clearly visible. Myelinization of the fibers of the hemispheric system is considered completed as early as the 8th month of intrauterine development of the fetus, after which it occurs for many years in individual fibers.
Therefore, not only the myelination of nerve fibers, but also the regulation and development of the mental state and the anatomical and physiological characteristics of the child and his nervous system take place in the process of his life.
Diseases
Doctors say they can't name a single one childhood disease with the absence physiological features and changes in the work of the heart or central nervous system. Such a statement especially applies to children under 5 years of age, and the younger the child, the more peculiar the manifestation of reactions from the vessels and the central nervous system.
Such reactions include respiratory and circulatory disorders, facial muscle amimia, skin itching, chin shaking, and other physiological symptoms indicating brain tissue damage. Diseases of the central nervous system are very different, and each has its own characteristics. To treat her immaturity, respectively, they also need to be different. And remember: in no case should you self-medicate!
- Poliomyelitis - occurs under the influence of a filtering virus that enters the body orally. Among the sources of infection are sewage and food, including milk. Antibiotics can't treat poliomyelitis, they don't work on it. This disease characterized by elevated body temperature, a variety of signs of intoxication and various autonomic disorders - itching, dermographism skin And excessive sweating. First of all, this virus negatively affects blood circulation and respiration.
- Meningococcal meningitis, caused by meningococcus, usually occurs in children younger than 1 to 2 years of age. The virus is unstable and therefore usually external environment under influence various factors dies pretty quickly. The pathogen enters the body through the nasopharynx and spreads extremely quickly to the entire body. With the onset of the disease, there is a sharp jump in temperature, hemorrhagic rashes appear, causing itching of the skin, which cannot be soothed.
- Purulent secondary meningitis - occurs most often in children under 5 years of age. This disease develops rapidly after purulent otitis media, with a sharp rise in the patient's body temperature, anxiety in children, headache, itching is possible. It is dangerous due to the possibility of the virus penetrating into the membranes of the brain.
- Acute serous lymphocytic meningitis is distinguished by the instant development of its symptoms. Body temperature literally in minutes rises to 39-40 degrees. The patient feels a strong headache, which cannot be calmed even with pills, vomiting occurs and momentary loss child's consciousness. But the disease does not affect the internal organs.
- Acute encephalitis - appears in a child in the event of the development of an appropriate infection. The virus has a negative effect on the walls of blood vessels, causing disturbances in the functioning of the heart and other physiological disorders. The disease is quite severe. At the same time, the patient's body temperature rises, there is a loss of consciousness, vomiting, itching, as well as convulsions, delirium and other mental symptoms.
Any suspicion of any of the above diseases is a reason to urgently call a doctor, after reassuring the child.
The defeat of the system before birth and after
Except viral diseases, the diagnosis of “lesion of the central nervous system in newborns” is relatively often made. It is possible to detect it at any time: both during the intrauterine development of the fetus, and at the time of childbirth. Its main reasons are considered birth trauma, hypoxia , intrauterine infections, malformations, chromosomal pathologies and heredity. The first assessment of the maturity of the system, mental state and anatomical and physiological features is made immediately after the birth of the baby.
Such a child is easily excitable, often crying for no reason when he is nervous, his chin is shaking, sometimes he suffers from skin itching, strabismus, head tilting, muscle tone and other physiological symptoms of a mental disorder are observed. During tantrums, the child is almost impossible to calm down.
We strengthen the nerves
Exists whole complex strengthening methods. It is a long, but quite effective process, aimed at both calming the baby and general improvement of his emotional, mental and nervous state. And above all, try to surround the child with calm and balanced people who are ready to immediately come to his aid.
We evoke positive emotions
The first thing to start with is to learn to control and regulate children's emotions and its anatomical, physiological and nervous state. There are a number of exercises that develop the muscles of the child and soothe him. For example, a baby helps riding a ball. It is advisable that both parents be near the baby during the exercises. It is the joint actions of the parents that give their child self-confidence, which in the future will only have a positive effect on determining his place in society.
Relaxing massage
The next point of the complex is a massage using various oils preventing skin itching. A massage session can only be carried out by a highly qualified specialist who is well acquainted with the methods of influencing the anatomical and psychological state and physiological processes in the human body. beneficial effect Quiet and calm music, especially the works of Mozart, has an effect on the child's psyche. The duration of one such massage session should be about 30 minutes. Depending on the mental state, nervous and vascular system, the child is prescribed different occasions 10 to 15 massage sessions. The assessment of his mental state is made by the doctor individually.
Proper nutrition
Proper nutrition of children, especially those under 5 years old, is one of the main ways to strengthen the nervous and vascular systems of a child. It is important to exclude sweet and carbonated drinks, flavorings and dyes, semi-finished products from the baby's diet, whose quality often leaves much to be desired. But be sure to eat eggs, fatty fish, butter, oatmeal, beans, berries, dairy and sour-milk products, lean beef.
Taking vitamins and minerals
Strengthening the nervous, vascular and other systems and normal anatomical, physiological and mental state the body is greatly facilitated by the intake of vitamins. Vitaminization is especially relevant in the season of colds, when the physiological forces of the body are at the limit. From a lack of vitamins in the body, memory, mood, and the general condition of the body worsen. That is why the regulation of the amount of vitamins and minerals in the body is so important.
For example, calcium deficiency negatively affects general condition. The child has hyperreactivity, it is possible nervous tics, convulsions, pruritus.
Physical activity
Regulation of the cardiovascular and nervous systems, myelination of nerve fibers are associated with exercise. They bring the body into tone and help improve mood, general and anatomical and physiological development of the brain, thereby significantly reducing the risk of developing various ailments of the nervous and cardiovascular systems. Swimming and yoga are best for older children.
Daily regime
Since childhood, we have been told about the importance of observing the daily routine - and not in vain. Mode is extremely important for children. Take care of the full sleep of the child, which has a significant impact on the nervous and cardiovascular systems. Go to bed and wake up at the same time every day. Also, daily walks in the fresh air contribute to the saturation of the body with oxygen, which is necessary in the anatomical and physiological development.
Every parent should be aware that the neuropsychic development of the child largely depends on him.
During this period of development, the child is still not very independent, needs the guardianship and care of an adult. Only towards the end of this period does it become possible to move independently in space - the baby begins to crawl. Around the same moment, an elementary understanding of reversed speech appears - individual words. There is no own speech yet, but onomatopoeia is developing very actively. This is a necessary step in the transition to independent speech. The child learns to control not only speech movements, but also the movements of his hands. It grabs objects and actively explores them. He really needs emotional contact with adults. On this age stage the emergence of new opportunities for the child is strictly genetically determined and, accordingly, these new opportunities should appear in a timely manner. Parents need to be vigilant and not console themselves with thoughts that their child is “just lazy” or “fat” and therefore cannot begin to roll over and sit up.
Age tasks: implementation of genetic development programs (the emergence of new types of movements, cooing and babbling) strictly within certain time limits.
The main motivation for cognitive development: the need for new experiences, emotional contact with an adult.
Leading activity: Emotional communication with an adult.
Acquisitions of this age: By the end of the period, the baby is forming selectivity in everything from movements and attention to relationships with others. The child begins to form his own interests and passions, he begins to be sensitive to the differences between the objects of the external world and people. He begins to use new skills for their intended purpose and reacts differently in different circumstances. For the first time, actions of his own inner impulse become available to him, he learns to control himself and influence others.
Development of mental functions
Perception: At the beginning of the period, it is still difficult to talk about perception as such. There are separate sensations and reactions to them.
A child, starting from the age of one month, is able to fix his gaze on an object, image. Already for a 2-month-old baby, a particularly important object of visual perception is human face, and on the face - eyes . The eyes are the only detail that babies can distinguish. In principle, due to the still weak development visual functions(physiological myopia), children of this age are not able to distinguish their small signs in objects, but only catch the general appearance. Apparently, the eyes are something so biologically significant that nature has provided for their perception. special mechanism. With the help of the eyes, we convey to each other some emotions and feelings, one of which is anxiety. This feeling allows you to activate the defense mechanisms, bring the body into a state of combat readiness for self-preservation.
The first six months of life is a sensitive (sensitive to certain influences) period during which the ability to perceive and recognize faces develops. People deprived of sight in the first 6 months of life lose their full ability to recognize people by sight and distinguish their states by facial expressions.
Gradually, the child's visual acuity increases, and systems mature in the brain that allow one to perceive objects of the outside world in more detail. As a result, by the end of the period, the ability to distinguish small objects improves.
By 6 months of a child's life, his brain learns to "filter" incoming information. The most active reaction of the brain is observed either to something new and unfamiliar, or to something that is familiar to the child and emotionally significant.
Until the very end of it age period the infant does not have any hierarchy of significance of the various attributes of an object. The infant perceives the object as a whole, with all its features. One has only to change something in the object, as the baby begins to perceive it as something new. By the end of the period, a constancy of form perception is formed, which becomes the main feature on the basis of which the child recognizes objects. If earlier change individual details made the child think that he was dealing with a new object, now the change in individual details does not lead to the identification of the object as new if it general form remains intact. The exception is the mother's face, whose constancy is formed much earlier. Already 4-month-old babies distinguish the face of the mother from other faces, even if some details change.
In the first half of life, there is an active development of the ability to perceive speech sounds. If newborn children are able to distinguish different voiced consonants from each other, then from about 2 months of age it becomes possible to distinguish voiced and deaf consonants, which is much more difficult. This means that the child's brain can sense differences on such a subtle level and, for example, perceive sounds like "b" and "p" as different. This is very important property, which will help the assimilation of the native language. At the same time, such a distinction between sounds has nothing to do with phonemic hearing - the ability to distinguish those characteristics of the sounds of the native language that carry a semantic load. phonemic hearing begins to form much later, when the words of the native speech become meaningful for the child.
A 4-5 month old child, hearing a sound, is able to identify the facial expressions corresponding to the sounds - he will turn his head towards the face that makes the corresponding articulatory movements, and will not look at the face whose facial expressions do not match the sound.
Children who at the age of 6 months are better at distinguishing similar sounds speech sounds, subsequently demonstrate the best development of speech.
Different types of perception in infancy are closely related to each other. This phenomenon is called "polymodal convergence". An 8-month-old child, having felt the object, but not being able to examine it, later recognizes it as a familiar one upon visual presentation. Due to the close interaction of different types of perception, the infant may feel the discrepancy between the image and sound and, for example, be surprised if a woman's face speaks in a man's voice.
The use of different types of perception in contact with the object is very important for the infant. He must feel any thing, put it in his mouth, turn it around before his eyes, he needs to shake it or knock on the table, and even more interesting, throw it with all his might on the floor. This is how the properties of things are known, and this is how their holistic perception is formed.
By 9 months, visual and auditory perception gradually becomes selective. This means that babies become more sensitive to certain, more important, characteristics of objects, and lose sensitivity to others, which are not significant.
Infants up to 9 months of age are able to distinguish not only human faces, but also the faces of animals of the same species (for example, monkeys). By the end of the period, they cease to distinguish representatives of the animal world from each other, but their sensitivity to the features of the human face, to his facial expressions intensifies. visual perception becomes electoral .
The same applies to auditory perception. Children aged 3-9 months distinguish the sounds of speech and intonation not only of their own, but also of foreign languages, melodies not only of their own, but also of other cultures. By the end of the period, infants no longer distinguish between speech and non-speech sounds of foreign cultures, but they begin to form clear ideas about the sounds of their native language. auditory perception becomes electoral . The brain forms a kind of "speech filter", due to which any audible sounds are "attracted" to certain patterns ("prototypes"), firmly fixed in the infant's mind. No matter how the sound “a” sounds in different cultures (and in some languages different shades of this sound carry a different semantic load), for a baby from a Russian-speaking family it will be the same sound “a” and the baby, without special training, will not be able to feel the differences between the sound "a", which is a little closer to "o", and the sound "a", which is a little closer to "e". But, it is thanks to such a filter that he will begin to understand the words, with whatever accent they may be pronounced.
Of course, it is possible to develop the ability to distinguish the sounds of a foreign language even after 9 months, but only through direct contact with a native speaker: the child must not only hear someone else's speech, but also see articulatory facial expressions.
Memory: In the first six months of life, memory is not yet a purposeful activity. The child is not yet able to consciously remember or recall. His genetic memory is actively working, thanks to which new, but programmed in a certain way, types of movements and reactions appear, which are based on instinctive urges. As soon as propulsion system the child matures to the next level - the child begins to do something new. The second active type of memory is direct memorization. An adult person remembers intellectually processed information more often, while a child is not yet capable of this. Therefore, he remembers what he needs (especially emotionally colored impressions) and what is often repeated in his experience (for example, coincidences certain types hand movements and the sound of a rattle).
Speech comprehension: By the end of the period, the child begins to understand some words. However, even if in response to a word he looks at the corresponding correct object, this does not mean that he has a clear connection between the word and the object, and he now understands the meaning of this word. The word is perceived by the infant in the context of the whole situation, and if something in this situation changes (for example, the word is pronounced in an unfamiliar voice or with a new intonation), the child will be at a loss. Surprisingly, the understanding of a word at this age can be affected even by the position in which the child hears it.
Own speech activity: At the age of 2-3 months, cooing appears, and from 6-7 months - active babbling. Cooing is a child's experimentation with different kinds of sounds, and babble is an attempt to imitate the sounds of the language spoken by parents or guardians.
Intelligence: By the end of the period, the child becomes capable of a simple categorization (assignment to one group) of objects based on their shape. This means that he can already, at a rather primitive level, detect similarities and differences between different objects, phenomena, people.
Attention: During the entire period, the attention of the child is mainly external, involuntary. At the heart of this type of attention is the orienting reflex - our automatic reaction to changes in the environment. The child cannot yet own will focus on something. By the end of the period (about 7-8 months), internal, voluntary attention appears, regulated by the child's own impulses. So, for example, if a 6-month-old child is shown a toy, he will look at it with pleasure, but if he covers it with a towel, he will immediately lose interest in it. A child after 7-8 months remembers that under the towel there is an object that is not visible now, and will wait for it to appear in the same place where it disappeared. How longer baby of this age is able to expect the appearance of a toy, the more attentive he will be at school age.
Emotional development: At the age of 2 months, the child is already socially oriented, which manifests itself in the "revitalization complex". At 6 months, the child becomes able to distinguish between male and female faces, and by the end of the period (by 9 months) - different facial expressions, reflecting different emotional states.
By 9 months, the child develops emotional preferences. And this again shows selectivity. Up to 6 months, the baby easily accepts the “deputy” mother (grandmother or nanny). After 6-8 months, children begin to worry if they are weaned from their mother, there is a fear of strangers and strangers, and babies cry if a close adult leaves the room. This selective attachment to the mother arises because the baby becomes more active and begins to move independently. He explores the world around him with interest, but research is always a risk, so he needs safe place where he could always return in case of danger. The absence of such a place causes great anxiety in the baby ().
Learning mechanism: One of the most common ways to learn something at this age is by imitation. An important role in the implementation of this mechanism is played by the so-called "mirror neurons", which are activated both at the moment when a person acts independently, and at the moment when he simply observes the actions of another. In order for a child to observe what an adult is doing, the so-called “attached attention” is necessary. This is one of the most important components of socio-emotional behavior, which underlies all productive social interactions. “Launching” of attached attention can only be carried out with the direct participation of an adult. If the adult does not look the child in the eye, address the child, or use pointing gestures, attached attention has little chance of developing.
The second learning option is trial and error, however, without imitation, the result of such learning can be very, very strange.
Motor functions: At this age, genetically determined motor skills develop rapidly. Development occurs from generalized movements with the whole body (in the structure of the revitalization complex) to electoral movements . The regulation of muscle tone, posture control, motor coordination are formed. By the end of the period, clear visual-motor coordinations appear (eye-hand interaction), thanks to which the child will subsequently be able to confidently manipulate objects, trying to act with them in different ways, depending on their properties. Details of the appearance of different motor skills during this period can be found in table . Movement during this period is one of the most important components of behavior that affect the cognitive development. Thanks to eye movements, viewing becomes possible, which greatly changes the entire system of visual perception. Thanks to groping movements, the child begins his acquaintance with the objective world, and he forms ideas about the properties of things. Thanks to the movements of the head, it becomes possible to develop ideas about the sources of sound. Due to the movements of the body, the vestibular apparatus develops, and ideas about space are formed. Finally, it is through movement that the child's brain learns to control behavior.
Activity indicators: Sleep duration healthy child from 1 to 9 months is gradually reduced from 18 to 15 hours a day. Accordingly, by the end of the period, the baby is awake for 9 hours. After 3 months, usually installed night sleep lasting 10-11 hours, during which the child sleeps with single awakenings. By 6 months, the baby should no longer wake up at night. During the day, a child under the age of 9 months can sleep 3-4 times. The quality of sleep at this age reflects the state of the central nervous system. It is shown that many children of preschool and younger school age, suffering from various behavioral disorders, unlike children without behavioral abnormalities, did not sleep well in infancy - they could not fall asleep, often woke up at night and, in general, slept little.
During the period of wakefulness, a healthy child enthusiastically engages in toys, communicates with adults with pleasure, actively coos and babbles, and eats well.
Major events in infant brain development from 1 to 9 months of age
By the first month of life, many events in the life of the brain are almost completed. New nerve cells are born in small numbers, and the vast majority of them have already found their permanent place in the structures of the brain. Now the main task is to get these cells to exchange information with each other. Without such an exchange, the child will never be able to understand what he sees, because each cell of the cerebral cortex that receives information from the organs of vision processes some one characteristic of the object, for example, a line located at an angle of 45 ° to the horizontal surface. In order for all perceived lines to form a single image of an object, brain cells must communicate with each other. That is why, in the first year of life, the most turbulent events concern the formation of connections between brain cells. Due to the emergence of new processes of nerve cells and the contacts that they establish with each other, the volume of gray matter increases intensively. A kind of "explosion" in the formation of new contacts between the cells of the visual areas of the cortex occurs in the region of 3-4 months of life, and then the number of contacts continues to gradually increase, reaching a maximum between 4 and 12 months of life. This maximum is 140-150% of the number of contacts in the visual areas of the brain of an adult. In those areas of the brain that are associated with the processing of sensory impressions, the intensive development of intercellular interactions occurs earlier and ends faster than in areas associated with the control of behavior. The connections between the cells of the baby's brain are redundant, and this is what allows the brain to be plastic, ready for different scenarios.
No less important for this stage of development is the coating of nerve endings with myelin, a substance that promotes the rapid conduction of a nerve impulse along the nerve. As well as the development of contacts between cells, myelination begins in the posterior, "sensitive" areas of the cortex, and the anterior, frontal areas of the cortex, which are involved in controlling behavior, are myelinated later. The beginning of their myelination falls on the age of 7-11 months. It is during this period that the infant develops internal, voluntary attention. Myelin coverage of deep brain structures occurs earlier than myelination of cortical regions. This is important, since it is the deep structures of the brain that carry a greater functional load in the early stages of development.
By the end of the first year of life, a child's brain is 70% the size of an adult's brain.
What can an adult do to support a child's cognitive development?
It is important to try to eliminate obstacles that impede free development. So, if a child does not develop any of the skills in a timely manner, it is necessary to check whether everything is in order with his muscle tone, reflexes, etc. This can be done by a neurologist. If the interference becomes obvious, then it is important to eliminate it in a timely manner. In particular, when we are talking about impaired muscle tone ( muscular dystonia), a great help is provided by therapeutic massage, physiotherapy and access to the pool. In some cases, medical treatment is required.
It is very important to create conditions conducive to development. The creation of conditions means giving the child the opportunity to realize his genetic program without restrictions. So, for example, you can’t keep a child in an arena, not allowing him to move around the apartment, on the grounds that dogs live in the house and the floor is dirty. To create conditions also means to provide the child with enriched sensory environment. Cognition of the world in its diversity is what develops the child's brain and forms the backlog of sensory experience that can form the basis of all subsequent cognitive development. The main tool that we are used to using to help a child get to know this world is. A toy can be anything that can be grabbed, lifted, shaken, put in the mouth, thrown. The main thing is that it is safe for the baby. Toys should be varied, differing from each other in texture (soft, hard, smooth, rough), in shape, in color, in sound. The presence of small patterns or small elements in the toy does not play a role. The child is not yet able to see them. We should not forget that in addition to toys, there are other means that stimulate the development of perception. This is a different environment (walks in the forest and in the city), music and, of course, communication with the child of adults.
Manifestations that may indicate problems in the state and development of the central nervous system
The absence of a "revitalization complex", the child's interest in communicating with an adult, attached attention, interest in toys and, on the contrary, acute auditory, skin, olfactory sensitivity may indicate a dysfunction in the development of brain systems involved in the regulation of emotions and social behavior. This situation may be a harbinger of the formation of autistic traits in behavior.
Absence or late appearance cooing and babbling. This situation may be a harbinger of delayed speech development. Too early appearance of speech (first words) may be the result of insufficient cerebral circulation. Early doesn't mean good.
Untimely appearance (too early or too late appearance, as well as a change in the sequence of appearance) of new types of movements can be the result of muscular dystonia, which, in turn, is a manifestation of suboptimal brain function.
Restless behavior of the child, frequent crying, screaming, restless, intermittent sleep. This behavior, in particular, is characteristic of children with increased intracranial pressure.
All of the above features should not go unnoticed, even if all relatives unanimously claim that one of them was exactly the same in infancy. Assurances that the child will “outgrow” himself, “will someday speak” should not serve as a guide to action. So you can lose precious time.
What should an adult do to prevent disorders of subsequent development if there are symptoms of trouble
Consult a doctor (pediatrician, pediatric neurologist). useful to do the following studies that can show the cause of trouble: neurosonography (NSG), eoencephalography (EchoEG), Doppler ultrasound (USDG) of the vessels of the head and neck, electroencephalography (EEG). Contact an osteopath.
Not every doctor will prescribe these examinations and, as a result, the proposed therapy may not correspond to the true picture of the state of the brain. That is why some parents report the absence of the result of drug therapy prescribed by a pediatric neurologist.

Often takes toys from the hands of an adult. With two hands, he grabs objects that are above the chest, and then above the face and on the side, feels his head and legs. Grabbed objects can be held between the palms for several seconds. Squeezes the palm on the toy put into the hand, first grabs with the whole palm without abducting the thumb (“monkey grip”). Releases toys held with one hand when another object is placed in the other hand. |

Rolls over from stomach to back. Grabbing the fingers of an adult or the bars of the crib, he sits down on his own, and for some time remains in this position, bending forward strongly. Some children, especially those who spend a lot of time on their stomach, before learning to sit down, begin to crawl on their stomach, moving with their hands around their axis, then back and a little later forward. They sit down generally later, and some of them first stand at the support and only then learn to sit down. This order of development of movements is useful for the formation of correct posture. |

Tremor in babies is most often twitching of the arms and chin. Similar to muscle hypertonicity, tremor is considered a sign of the lack of a sufficient level of maturity of the baby's nervous system, its significant excitability.
Most often, muscle contractions in newborns are recorded periodically during a strong fright, screaming, crying, REM sleep (with noticeable eye movements) or hunger.
If the intensity of tremor in newborns is high, and the amplitude is small, then these are the features of the nervous system of the newborn.
Tremor is a fairly common occurrence, occurring in about half of newborns, and is considered normal in the first months of life (by 3-4 months, all signs of tremor should disappear).
Tremor of the chin in a newborn under the age of 1 year also rarely causes concern and does not require treatment as it is often a benign, age-dependent, specific condition of the nervous system.
However, if parents notice a tremor in a child, it is better to consult a pediatrician.
The nervous system of an infant is very flexible and highly receptive to external influences, so the right treatment can easily normalize and restore it.
Causes of tremor in infants
Tremors are most often caused by be:
- immaturity of the nervous system;
- fetal hypoxia;
- premature birth.
Immaturity of the nervous system
In the first weeks of a baby's life, he lacks coordination of movements, the nervous system is characterized by immaturity. These factors cause tremor of the extremities in newborns.
Muscle hypertonicity also increases the likelihood of tremors. Also, during the manifestation of emotions, an increased content of norepinephrine can be observed in the blood of the baby.
Fetal hypoxia
During pregnancy and during childbirth, there is a risk of violations placental blood flow, which can negatively affect the processes in the brain. Hypoxia may be consequence:
- intrauterine infection;
- violations of the functionality of the placenta;
- bleeding;
- increased tone of the uterus (threat of miscarriage);
- polyhydramnios.
Problems with the child's nervous system can be called like rapid delivery, and weak labor activity
as well as placental abruption and 
entanglement of the fetus with the umbilical cord.
The above factors impede the access of oxygen to the brain, which leads to the appearance of tremor tremor of the arms, legs and chin in newborns.
preterm birth
A premature baby is most often prone to tremor of the lips, legs or chin.
This is because their nervous system, in principle, does not differ in maturity. She has to complete her formation already outside the mother's womb, where there are not, and cannot be any close to her conditions, even in the case of adequate and careful care.
Tremor of what organs is most often present in infants?
Most common in newborns observed:
- head tremor (reason - immaturity of the nervous system);
- tremor of the hands (less often of the legs), chin and lips (reason - prematurity).
When is Targeted Treatment Necessary?
If signs of tremor are observed for more than 3 months, spread to the legs and head, and are not associated with the peculiarities of the nervous system or the feeling of hunger, then this should cause anxiety among parents.
So can appear:
- intracranial hemorrhage;
- hyperglycemia;
- hypocalcemia;
- hypoxic-ischemic encephalopathy;
- hypomagnesemia;
- narcotic withdrawal syndrome;
- sepsis and increased intracranial pressure.
Targeted treatment of tremor in newborns is mandatory after a traumatic brain injury or an infectious disease.
In such cases, systematic monitoring should be carried out by a pediatric neurologist.
Treatment methods
Method of treatment of tremor of hands, feet, head in a child aimed at restoring the health of the baby in general and the nervous system in particular.
Massage for tremor in the baby
In addition, parents should definitely create a pleasant, cozy and friendly environment around their baby, systematically Do massage to your baby (it promotes relaxation), to instill swimming skills (this is real even in a home bath), to do therapeutic exercises with him.
Such efforts of parents will not be in vain.
It is easiest to master the massage technique for newborns at home (from the age of 5-6 weeks). The pediatrician will definitely teach mom and dad the basic massage movements, on the basis of which you can then proceed to perform various exercises.
Basic movements massages are:
- vibration;
- kneading;
- trituration;
- stroking.
The basic rule is that all massage movements are performed from the periphery to the center (along the joints).
plays an important role mental attitude baby and his physical comfort during massage:
How it manifests itself and signs that will leave no doubt.

Basic exercises
Here are a few basic exercises:
- "Hammer". When the child is lying on his back, you need to grab with one hand right foot, and with the other fist knock on outside legs from bottom to top. Next, the exercise is repeated with the foot of the other leg.
- "We iron hands". The baby's handle is fixed with the left hand, and the right hand gently wraps around the shoulder. Going down to the wrist, you should make shaking movements. Exercise is done 2-3 times and transferred to the other hand. Using a similar tactic, you can perform the exercise "Stroking the legs."
- "Watch". Exercise also helps children with bowel problems. The baby's tummy should be stroked clockwise for 5-7 minutes.
- "Toptyzhka". The baby lies on the tummy, and the massage therapist gently kneads the buttocks with his fists. To occupy the baby, it is recommended to put a bright interesting toy in front of him. He will look at her, reach for her and thus the spinal and cervical muscles are involved.
- "Herringbone". In the direction from the back to the coccyx and at an angle to the spine, it is necessary to make stroking movements.
conclusions
Pediatrics operates with the concept of a critical time in the development of a child after birth, especially this applies to the nervous system, disturbances in which can cause tremor in newborns.
Critical periods are the 1st, 3rd, 9th and 12th months of a baby's life, when the nerve endings are highly sensitive and any deviation from the norm can lead to the development of certain pathologies.
To prevent development serious problems , which can be the cause of tremor, systematic monitoring of the child's health is strongly recommended. Noticing signs of tremor in a newborn, there is no need to panic, but you should definitely contact a neurologist.
