Autism is a complex developmental disability that typically appears during the first three years of life. The result of a neurological disorder that affects the functioning of the brain, autism and its associated behaviors have now been estimated to occur in as many as 1 in 150 individuals (Center for Disease Control and Prevention). Autism is four times more prevalent in boys than girls (1 in 94 boys) and knows no racial, ethnic or social boundaries. Family income, lifestyle, and educational levels do not affect the chance of autism’s occurrence.
Autism impacts the normal development of the brain primarily in the areas of social interaction and communication skills. Children and adults with autism typically have difficulties in communication, social interactions, and leisure or play activities. The disorder makes it hard for them to communicate with others and relate to the outside world. In some cases aggressive and/or self-injurious behavior may be present. Persons with autism may exhibit repeated body movements (hand flapping, rocking, etc), unusual responses to people or attachments to objects, and resistance to changes in routines.
Over one and a half million people in the U.S. today have autism or some form of pervasive developmental disorder. Autism is the most common of the pervasive developmental disorders
