Autism is a disorder of mental development, accompanied by a deficit of social interactions, difficulty in mutual contact when communicating with other people, repetitive actions and limited interests. The reasons for the development of the disease are not fully understood; most scientists assume a connection with congenital brain dysfunction. Autism is usually diagnosed before the age of 3, and the first signs can be seen as early as infancy. Full recovery is considered impossible, but sometimes the diagnosis is removed with age. The goal of treatment is social adaptation and the development of self-care skills.
