| What is Autism? Autism is a complex developmental disability that typically appears during the first three years of life. It is currently believed to have a genetic basis that affects the neurological development of the brain, though some theories connect autism with specific environmental factors or other triggers. The incidence of autism spectrum disorder is estimated to occur in as as many as 1 in 160 individuals and is four times more prevalent in boys than girls. Autism knows no ethnic, social or economic boundaries. The prevalence rate now places it as the third most common developmental disability - more common than Down Syndrome. Autism interferes with brain development in the areas of social interaction and communication skills. Children and adults with autism typically have difficulties in both verbal and non-verbal communication, social interactions, sensory integration, and leisure or play activities. This disorder makes it hard for individuals to communicate with others and relate to the outside world. They may exhibit repeated body movements (hand flapping, rocking), unusual responses to people or attachments to objects, and they may resist changes in routines.
