Causes of Autism Spectrum Disorders
The reasons leading to the development of autism spectrum disorders are not fully understood. Since the 70s of the last century, various theories of the onset of the disease “autism” began to appear. Some of them did not justify themselves over time and were rejected (for example, the “cold mother” theory).
Currently, ASD is considered a polyetiological disease, which can develop due to several factors. Among the reasons are:
HEREDITARY PREDISPOSITION
Genetically altered genes are one of the main causes of autism and, why this disease arises and develops. Autism is inherited, which means that autistic children were initially susceptible to it at the genetic level. It is heredity that is the reason why several children in one family suffer from such a disease. And scientific studies show that the risk of developing autism among sisters and brothers increases three to eight times.
