autism and child development-Part Two

1. Syndrome Rett- situation observed for now only in girls, in which apparently narmalnoto early development is usually followed by partial or complete loss of speech and movement skills and use of arms, together with deceleration of the head. Home typically in vazrarastta in between 7 and 24 months. It is characterized by loss of purposeful hand movements and hyperventilation. Development of social skills and the game remain at the level of the first two - three years, but tend to preserve social interests. At the age of about four years began to develop apraxia / violation of gestural activity in healthy organization and kodrdinatsionnite motor functions are not affected, in which there is full understanding of the act, ie no intellectual deficiency of the body that are often followed by choreoathetosis / otrevizti sudden movements, both diverse and unpredictable movements. Almost invariably leads to severe mental retardation.
In about half of the cases in adolescence or adulthood develop spinal atrophy with severe defects in motility. Later may appear rigid plasticity, usually severe in the lower than in the upper limbs.
2. Another dezentegrativno disorder in detstvoto- type generalized disorder in the development / non-syndrome Rett /, which is determined by the existence of a period of apparently normal development of the disorder to hurt. Then, for several months, there is a clearly defined period of loss of previously mastered skills, covering several areas of development. This is usually accompanied by a general loss of interest in the environment of sretiotipni, repetitive motor mannerisms and violated, such as autism social interaction and communication.
Often there is a period of vague illness: the child becomes drowsy and irritable, anxiety and hyperactivity, and then loss of speech and language, accompanied by behavioral dezentegratsiya.
In some cases, the loss of skills is hard progressive / usually when the disorder is combined with demonstrable progressive neurological disease /., But more often fall for a period of several months followed by a gradual, then a slight improvement. The prognosis is usually very poor, most people are left with severe mental retardation. There is uncertainty to what extent this situation is different from autism. In some cases, the disorder may be due to the accompanying encephalopathy / wide nosological group which covers all organic brain damage / but the diagnosis must be placed on the basis of behavioral signs.
3. Hyperactive Disorder, combined with mental retardation and stereotypes dvizheniya- This is a poorly defined disorder of uncertain nosological validity. This category is included here for the following reasons:
· Children with severe mental retardation / IQ below 50 /, the main problems are hyperactivity and attention deficit disorder and behavior stereotypes.
· Generally not affected by stimulants well / as opposed to those with IQ in the normal range / and can react with severe dysphoria / psychomotor retardation sometimes when they give such medication.
• In adolescence hyperactivity is often replaced with hypo / type of development, which is not typical for hiraktivnite children with normal intelligence /.
Often this syndrome combined with various delays in development, specific or general. It is not clear whether behaviors are due to low IQ or of organic brain damage.

The diagnosis depends on a combination of inadequate level of development of severe hyperactivity, motor stereotypes and severe mental retardation. All three must be from a person to put the diagn
