Autism is defined as the neuro biological disorder characterized by severe deficiency in social skills, behavior and reciprocal social interactions; difficulty in language, arrangement of words and non verbal communication; intellectual and cognital deficiency; difficulty in identifying and remembering the names and nature of things.
It is a developmental disorder that appears in the first three years of life and affects the brain’s normal development of social and communication skills. Some children with autism appear normal before age 1 or 2 and then suddenly regress and lose language or social skills they had previously gained. It affects boys 3-4 times more often than girls.
