Theoretical aspects of diagnostics of autism disorder in children and its typology

The complexity of diagnosing and identifying a diagnosis in children with autistic disorder is due to the constantly changing clinical and mental picture of the manifestation of this disorder. Psychological and pedagogical, as well as correctional work with children with autism and autism spectrum disorder is complex, diverse and significantly different from other types of mental development disorders. Until now, the exact cause of the occurrence of autistic disorders has not been identified, but there is an assumption that this is some form of biological (organic), as well as neurological disorders of the central nervous system, causing deviations in the development of higher mental functions. Autistic disorders, which until recently were not considered a mental illness, were explained as the result of insufficient education not only on the part of parents, but also of specialists. Meanwhile, there is also no sufficiently substantiated evidence that autistic disorders may be the result of chemical-biological or external influences on the occurrence of this disorder in children and its study.
