Autism is a complex developmental disability that typically appears during the first three years of life. Autism is the result of a neurological disorder that affects the functioning of the brain. Autism and its associated behaviors have been estimated to occur in as many as 1 in 500 individuals. Autism is four times more prevalent in boys than girls.
Autism knows no racial, ethnic, or social boundaries.
Family income, life-style, and educational levels do not affect the chance of its occurrence. Autism interferes with the normal development of the brain in the areas of social interaction and communication skills. Children and adults with autism typically have difficulties in verbal and non-verbal communication, social interactions, and leisure or play activities. Autism makes it hard for these children and adults to communicate with others and relate to the outside world. People with autism may exhibit repeated body movements, unusual responses to people or sensory stimuli, and they may resist changes in routines.
