Autism is not an intellectual disease but rather a developmental disorder caused due to damage to the brain nerve cells. Autistic children usually have average or below-average intelligence. Autism affects the part of the brain that is associated with social communication and behaviors, and not intellect. However, some autistic children have been found to have an extraordinary development in non-communicative skills like drawing, music production, playing musical instruments, math skills, etc. It needs to be mentioned that this type of higher intellect in autistic children was found mostly in the less severely affected by autism and not in those who were affected severely.
