Features of children with mental retardation

Mental retardation (MDD)

– reduced intellectual functioning, limitation of adaptive perception, when certain mental functions (thinking, attention and memory) lag behind in development from established psychological norms for a certain age. The number of people with mental retardation is 15-16% in the pediatric population.

Mentally retarded people score low on intelligence (IQ) tests, but the impact on functioning in daily life depends on the severity of the disease and associated impairments. Symptoms of mental retardation in children include insufficient development of speech and motor skills, thinking and memory, regulation and self-regulation of behavior. About 85% of children with mild developmental delays usually learn to speak and become independent with timely intervention.

General information

Mental retardation in children can be caused by a large number of reasons (including pronounced congenital syndromes), and the symptoms of mental retardation manifest themselves not only in a decrease in cognitive abilities, but also in other physical and mental abnormalities.

Mental retardation is characterized by a violation of the intellectual and emotional-volitional spheres. This condition is accompanied by learning difficulties. We are talking primarily about the psychological and pedagogical category, but it can also be based on organic disorders.

Mental changes in mentally retarded children are stable and do not progress, so psychosomatic complications are unlikely. The diagnosis is made for preschool children at the age of 4-5 years or during schooling. The main difficulty for such patients is the lack of opportunity to fully adapt to society.

Clinical picture

Parents should be aware of the main symptoms of mental retardation characteristic of a particular age.

1 year

CPR is not diagnosed at 1 year of age. But a number of alarm bells may indicate a tendency towards it:

  • Compared to his peers, the baby began to hold his head up, sit up, crawl, turn, stand up, walk, walk late;
  • does not hold objects well;
  • cannot coordinate movements;
  • moves little;
  • unemotional.

In this case, it is necessary to take into account the individual developmental characteristics of the baby and, if in doubt, consult a pediatrician or neurologist.

2 years

Deviations are indicated by:

  • ignorance of one's own name;
  • lack of response to the simplest questions;
  • profuse drooling;
  • sleep disorders;
  • moodiness, tearfulness, irritability, aggression;
  • difficulty maintaining attention on a specific subject.

3 years

  • Poor vocabulary (no more than 20 words);
  • speech defects;
  • lack of basic understanding of the surrounding world (cannot name animals, household items, body parts);
  • inability to formulate coherent speech;
  • difficulty completing basic tasks;
  • undeveloped imagination;
  • uniformity of actions in the game;
  • inability to concentrate;
  • fast fatiguability;
  • aggressiveness, hysteria.

4 years

At 4 years of age, mental retardation is already clearly diagnosed based on specific symptoms.

Physical:

  • weak muscle tone;
  • kinetosis;
  • urinary disorders;
  • headache;
  • fatigue, weakness, lethargy, immobility.

Cognitive:

  • inability to speak coherently;
  • poor vocabulary;
  • absent-minded attention;
  • poor memory;
  • inability to remember information visually or auditorily;
  • lack of basic knowledge about the world;
  • lack of formation of cognitive motivation.

Social:

  • aggressiveness, distrust, wariness towards others;
  • isolation, autism, self-absorption;
  • reluctance to participate in joint games;
  • infantilism;
  • mood changes.

It is at the age of 4, with timely recognition of mental retardation, that corrective work must begin. In its absence, all these symptoms only increase and deepen at 5-6 years of age. Secondary signs appear: psychosomatic diseases and internal complexes develop, cognitive abilities deteriorate, and social maladaptation is observed.

At primary school age, mental retardation manifests itself more clearly. Such children differ from their peers in behavior and learning abilities. If parents and kindergarten teachers missed this moment and sent such a child to school, the teacher can no longer help but pay attention to this. He needs to master the minimum standard program, without which he cannot transfer such a student to another class. Therefore, at this stage, a medical-pedagogical commission is organized, a diagnosis is made and psycho-correctional work begins.

Causes of mental retardation

Mental retardation in preschool children is a consequence of many different factors that ultimately lead to a defect in the neurobiological and functional development of the brain. Biological and social factors should be highlighted.

The most common causes of mental retardation in children

are:

· Embryonic development disorders: rubella, treponema, toxoplasma, cytomegalovirus, listeria, herpes infection, HIV. No less dangerous are placental dysfunction, alcohol, drug use, and smoking. Phenol poisoning, pesticides, lead and increased levels of radiation leave their mark.

· Perinatal problems: prematurity, hypoxia, intracranial hemorrhage, metabolic disorders in newborns, meningitis, severe brain injury, encephalitis.

· Severe somatic diseases of the child: rickets, neuroinfections, influenza. Epilepsy can also be a cause.

In some cases, the cause of mental retardation is heredity. This disease is diagnosed in some families from generation to generation. Congenital mental retardation is almost inevitable in many genetic diseases, for example: Patau, Edwards, Cornelia de Lange, Down syndrome.

Delayed development of a child of a secondary nature develops against the background of visual or hearing impairment. The cause may be a speech defect, as well as a severe deficit in communication and sensory information.

Mental retardation or dementia can be caused by abnormal brain development:

· insufficient brain size (microcephaly);

· complete or partial absence of the cerebral hemispheres (hydranencephaly);

· underdevelopment of the brain (lissencephaly);

Cerebellar hypoplasia (pontocerebellar hypoplasia).

Often the pathogenesis of mental development disorders lies in metabolic disorders or enzyme production (phenylketonuria). Postpartum mental retardation in children can also be caused by the destruction of red blood cells - hemolytic disease of the newborn. It occurs as a result of Rh conflict during pregnancy and leads to serious dysfunction of the cortex and subcortical neural nodes of the brain.

Among the social factors, one should highlight the influence of hypo- or hyperprotection, lack of opportunity to communicate with other people (for example, due to disability), authoritarian upbringing (unquestioning submission). Environmental factors, as a rule, cause mental retardation mainly in the presence of a primary organic basis for dysfunction.

What should parents do?

Psychologists and teachers who work directly with children who have mental retardation give useful recommendations to parents to speed up their development.

To begin with, parents will have to not only understand, but also accept the fact that the child will learn more slowly than his peers and lag behind them in his studies. In order not to demand too much from him, to be patient with his characteristics, they need to be studied and taken into account when communicating and studying.

Homework alone cannot solve the problem of mental retardation. Therefore, the second step for parents who want to help their child is to seek qualified help from specialized specialists - a special education teacher, a psychologist or a psychotherapist. Taking into account individual characteristics, they will give recommendations on what exactly needs to be done.

General tips:

  1. Exercise daily for 30-40 minutes.
  2. Pay more attention to the child, organize time together, communicate, involve other relatives.
  3. Provide a comfortable atmosphere in the family.
  4. Normalize the daily routine, introduce a healthy lifestyle, provide a balanced diet, increase physical activity and stay in the fresh air.
  5. Communicate with other parents of the same children (for example, through communities on social networks).
  6. Organize communication with peers.
  7. Don't tell your child that he is special. Do not regret that he is not like everyone else.
  8. Assign household chores, animal care, teach self-care.
  9. Don't raise your voice, be patient no matter what happens.
  10. Keep a diary to note all your successes - these entries will help you adjust your future work.

Classification

The classification of a person's intellectual indicators is based on the measurement of IQ. Depending on the amount of missing cognitive abilities, three degrees of oligophrenia are distinguished, which are applied regardless of the etiology of the disease:

· Mild (CIE 10-F70).

The level of intellectual development (CI) ranges from 50-69. Patients have minimal sensorimotor slowing. At preschool age they can develop communication skills, acquire some knowledge, and at a later age – professional skills.

· Medium degree (F71-F72).

They can understand other people’s speech, and at the age of 5-6 years they formulate short phrases. Thinking is limited, primitive. It takes a lot of effort to teach reading, writing, arithmetic and self-care skills.

· Severe (F73).

Thinking in this form is almost completely blocked (IQ below 20), all actions are limited to reflexes. Such children cannot learn (except for some development of motor skills) and require constant care.

The etiopathogenetic classification of ZPR includes four types of the disease. Constitutional genesis is characterized by a slowdown in the maturation of the central nervous system, which is accompanied by psychophysical and mental infantilism. This type of mental retardation, as somatogenic, is caused by long-term and severe somatic disorders of children at an early age (chronic dyspepsia, bronchial asthma, heart or kidney failure, etc.), which leads to disruption of the development and maturation of the central nervous system.

Mental retardation of psychogenic origin is associated with unfavorable social conditions (abuse, neglect). Due to attention deficit, impulsivity and mental instability are formed. With increased care, the child develops egocentrism and lack of initiative.

For mental retardation of cerebral-organic origin, organic damage to the brain is noted. This type of disease occurs most often. Disorders affect certain areas of the psyche or manifest themselves in different areas. It is characterized by immaturity of cognitive activity or the emotional-volitional sphere.

Exercises to develop attention

There are a large number of development methods. When using games in practice, it is permissible to change the conditions and adjust them to the child’s abilities. Some are made individually, others are intended for a group of children.

Exercise No. 1 A group of children is shown a set of words or pictures in an accessible way (cards, pictures, monitor). The one who can write down (remember) the most wins the competition. You can also award a victory for literacy. Mandatory reward for success.

Exercise No. 2 The child is presented with a set of pictures that need to be remembered. You need to name as many items as possible, preferably in the correct sequence.

Exercise No. 3 1 minute is timed and during this time the child is asked to name as many objects around him as possible. You can make it more complicated and name objects, for example, only yellow ones, or those that begin with the letter “O”. In addition, it is useful to let students solve riddles, labyrinths, and quests. For example, arrange a game in which the child must look for clue notes, and at the end a prize awaits him. Regular school exercises also develop concentration. Mathematics, reading, dictations, memorizing poetry. To prevent your child from losing interest, it is recommended to turn intellectual exercises into games to develop attention. To do this, a story is thought out in advance (travel, transformation into a magician) during which the child will complete tasks.

Characteristics of children with mental retardation

Complications of PVD vary depending on the specific cause. Children with Down syndrome have a higher incidence of cardiovascular complications than other patients. Mental retardation in a mild form allows a person to integrate and work normally. People with more severe delays may have poor physical functioning and need care throughout their lives.

Perception

Children with mental retardation perform perception and observation of objects, events, and situations in an insufficiently differentiated form. It is difficult for them to separate the characteristics of certain objects, as well as to make comparisons and understand the relationships that exist between objects.

Memory quality

The quality of memory is significantly reduced due to weak thinking. This prevents children with developmental delays from separating the essential from the non-essential, that is, connecting isolated elements with each other and using random and auxiliary associations.

These children have difficulty learning and remembering, making it difficult to transfer lessons learned to new situations. For this reason, organized events should take into account learning tools that help improve memory efficiency.

Speech skills

The speech of children with developmental delays develops with a delay. Vocabulary is small. They have limited understanding of the meaning of words and little generalization due to difficulties in language development, as well as difficulties in the function that regulates thinking and critical judgment.

Thinking

Thinking is formed in conditions of incomplete sensory perception, lack of language development, and limited practical activity. For this reason, mental functions develop slowly and have special characteristics.

Emotional sphere

The personal-volitional sphere is characterized by its immaturity, caused by insufficient development of cognitive activity, therefore children with mental retardation are limited in expressing their impressions, feelings and emotions. They can either react intensely to a minor motive, or show themselves weakly to serious life events.

Inadequate, superficial relationships of feelings, characteristic of children with mental retardation, as well as the inability to suppress their desires. They move from one mood to another, in some cases without motivating reasons. They are characterized by elements of infantilism and impulsiveness, as well as difficulties in prohibitions.

Children with mental retardation have difficulty concentrating on any activity, they show anxiety and are poorly motivated. When not treated properly, they react to disappointments at school with rebellious, aggressive behavior or great withdrawal. Their development outside of school or at a later stage is largely determined by how they relate to their environment and the people around them.

If a child with mental retardation finds understanding, sympathy, help and respect, then full development is possible within the limits of his abilities. But when sick children become victims of ridicule, rejection, and intolerance, this leads to serious changes in behavior and various decompensations.

Development of skills in working with patterns

Exercise “Repeat according to the example.”

This version of the task is suitable for developing the skill of making complex patterns that are identical to each other. Drawing each pattern will require high concentration of attention from a child with mental retardation, implying the execution of actions in a certain order:

  • analysis of individual pattern elements;
  • choosing a position for each of them;
  • maintaining a sequence of actions over time.

The teacher should first of all pay attention not to how the student copes with reproducing the sample, but to how long he is able to work without making mistakes. It is this indicator that will allow you to analyze the level of attentiveness. You need to start working on reproducing patterns from a few minutes; you can gradually increase the time and complicate the patterns.

To strengthen their skills in working with patterns, you can invite children to play the role of a teacher and check the finished patterns of other children, highlighting mistakes. By the way, you can check not only patterns, but also children’s dictations, examples and other tasks.

Diagnostics

The differential diagnosis of mental retardation should be made by personnel trained in the use of standardized psychometric methods. In early childhood, the first signs of mental retardation rarely appear and can be clearly expressed only after 4-5 years.

Today, the diagnosis of mental retardation is carried out by collecting anamnesis (obstetric data on the course of pregnancy and information on diseases of relatives), a general psychological and psychometric assessment of the patient. This makes it possible to assess the somatic state, establish the presence of not only physical (visually defined) signs of mental retardation, determine the level of intellectual development and compliance with their standards, as well as observe mental behavior and reactions.

To accurately determine the specific form of ZPR, you may need:

· general, biochemical and serological blood test;

· blood for syphilis and other infections;

· Analysis of urine.

Genetic testing is performed to identify congenital causes of the disease.

Instrumental diagnosis of developmental delay includes:

· encephalogram;

· computed tomography;

MRI of the brain.

Differential diagnosis is necessary. Despite some characteristic physical defects, many neurological disorders (paresis, convulsions, trophic and reflex disorders, epileptiform convulsions) are observed in other neuropsychiatric pathologies.

Even when the fact of inhibition and inadequacy is obvious, a thorough professional assessment of the mental abilities of children is necessary in order to distinguish a mild form of mental retardation from emotional-behavioral (psychiatric) disorders.

Correction of mental retardation

Treatment begins with timely identification of the problem. Depending on the degree of mental dysfunction, the child will be asked to complete standard school work designed for children of a similar age. Correction of mental retardation is carried out through educational intervention optimized depending on the degree of mental retardation. Children must be integrated into social, educational and cultural life with the rest of the population.

If the cause of mental retardation is hypothyroidism, Rh conflict, phenylketonuria, etiological treatment of mental retardation with the help of hormonal drugs, blood transfusion to the child, or a special diet without protein is possible. In most cases, there is no etiological treatment.

Patients with intellectual disabilities are treated with symptomatic therapy. Drugs are prescribed to reduce the intensity of psychotic disorders: antipsychotics, as well as medications to stabilize mood (which helps to correct behavior).

Reduce anxiety levels, stop crises and improve sleep with the help of psychoactive substances with tranquilizers. The negative consequences of their use are expressed in muscle weakness, increased drowsiness, impaired coordination of movements and speech, and decreased visual acuity. Long-term use of these drugs can compromise attention and memory, even leading to the development of anterograde amnesia.

One of the main roles in the correction of intellectual disability is given to cognitive-behavioral therapy, i.e., medical correctional pedagogy. To raise children with mental retardation in specialized schools and boarding schools, specially developed methods of adapting children to society are used.

Rehabilitation of patients with mental retardation, especially with genetically determined forms of mental pathology, consists not so much of their treatment as of teaching programs and instilling basic household and, if possible, simple social skills. Experts say that mild mental retardation in children can be corrected, and despite the disability, such patients can perform simple work and take care of themselves.

Prognosis and prevention

According to statistics, a quarter of mental development defects are associated with chromosomal abnormalities, so prevention is only possible for non-congenital pathologies.

Basic preventive measures:

· during the planned period of preparation for pregnancy, it is necessary to undergo a full examination for the presence of infections, eliminate all foci of inflammation and cure existing chronic diseases;

· check the condition of the thyroid gland and hormone levels;

· some types of mental retardation can be prevented through genetic counseling of future parents to identify disorders that are potentially dangerous for the normal development of the embryo and fetus;

· During pregnancy, women should regularly visit their doctor, take the necessary tests and undergo an ultrasound scan on time.

An important preventive measure for delaying the pace of development is the early detection of certain metabolic processes leading to mental retardation. If congenital hypothyroidism affecting a newborn is detected during the first month of life, the development of dysfunction can be prevented. If the problem is not identified and treated before the age of three months, then 20% of children with thyroid hormone deficiency will be mentally disabled.

Mental retardation (MDD) - treatment at the RebenOK clinic in Moscow

The medical center employs experienced doctors who identify the causes of developmental delay and take effective measures to eliminate them. Pediatricians, child neurologists, psychologists, as well as speech pathologists and speech therapists take part in the work. Correction requires a long period and begins from preschool age.

Patients with mental retardation at the RebenOK clinic receive speech correction in individual speech therapy sessions. Medical care includes drug therapy, which is prescribed in accordance with cerebral-organic and somatic disorders. Massage, exercise therapy and physiotherapy are also prescribed.

ZPR is a diagnosis that can be treated. The main thing is to start taking action in time. Sign up for the RebenOK clinic in Moscow, where the best doctors work and use new treatment methods developed based on international protocols.
