The following areas are among those that may be affected by autism:

Communication:
language develops slowly or not at all; uses words without attaching the usual meaning to them; communicates with gestures instead of words; short attention span;

Social Interaction:
spends time alone rather than with others; shows little interest in making friends; less responsive to social cues such as eye contact or smiles;

Sensory Impairment:
may have sensitivities in the areas of sight, hearing, touch, smell, and taste to a greater or lesser degree;

Play:
lack of spontaneous or imaginative play; does not imitate others' actions; does not initiate pretend games;

Behaviors:
may be overactive or very passive; throws tantrums for no apparent reason; perseverates (shows an obsessive interest in a single item, idea, activity or person); apparent lack of common sense; may show aggression to others or self; often has difficulty with changes in routine.

Some individuals with autism may also have other disorders which affect the functioning of the brain such as: Epilepsy, Mental Retardation, Down Syndrome, or genetic disorders such as: Fragile X Syndrome, Landau-Kleffner Syndrome, William's Syndrome or Tourette's Syndrome. Many of those diagnosed with autism will test in the range of mental retardation. Approximately 25-30 percent may develop a seizure pattern at some period during life.

Every person with autism is an individual, and like all individuals, has a unique personality and combination of characteristics. There are great differences among people with autism. Some individuals mildly affected may exhibit only slight delays in language and greater challenges with social interactions. The person may have difficulty initiating and/or maintaining a conversation, or keeping a conversation going. Communication is often described as talking at others (for example, monologue on a favorite subject that continues despite attempts of others to interject comments).

People with autism process and respond to information in unique ways. Educators and other service providers must consider the unique pattern of learning strengths and difficulties in the individual with autism when assessing learning and behavior to ensure effective intervention. Individuals with autism can learn when information about their unique styles of receiving and expressing information is addressed and implemented in their programs. The abilities of an individual with autism may fluctuate from day to day due to difficulties in concentration, processing, or anxiety. The child may show evidence of learning one day, but not the next. Changes in external stimuli and anxiety can affect learning. They may have average or above average verbal, memory or spatial skills but find it difficult to be imaginative or join in activities with others. Individuals with more severe challenges may require intensive support to manage the basic tasks and needs of living day to day.

Contrary to popular understanding, many children and adults with autism may make eye contact, show affection, smile and laugh, and demonstrate a variety of other emotions, although in varying degrees. Like other children, they respond to their environment in both positive and negative ways. Autism may affect their range of responses and make it more difficult to control how their bodies and minds react. Sometimes visual, motor, and/or processing problems make it difficult to maintain eye contact with others. Some individuals with autism use peripheral vision rather than looking directly at others.

 Sometimes the touch or closeness of others may be painful to a person with autism, resulting in withdrawal even from family members. Anxiety, fear and confusion may result from being unable to "make sense" of the world in a routine way. With appropriate treatment, some behaviors associated with autism may change or diminish over time. The communication and social deficits continue in some form throughout life, but difficulties in other areas may fade or change with age, education, or level of stress. Often, the person begins to use skills in natural situations and to participate in a broader range of interests and activities. Many individuals with autism enjoy their lives and contribute to their community in a meaningful way. People with autism can learn to compensate for and cope with their disability, often quite well.

While no one can predict the future, it is known that some adults with autism live and work independently in the community (drive a car, earn a college degree, get married); some may be fairly independent in the community and only need some support for daily pressures; while others depend on much support from family and professionals.

Adults with autism can benefit from vocational training to provide them with the skills needed for obtaining jobs, in addition to social and recreational programs. Adults with autism may live in a variety of residential settings, ranging from an independent home or apartment to group homes, supervised apartment settings, living with other family members or more structured residential care.

An increasing number of support groups for adults with autism are emerging around the country. Many self-advocates are forming networks to share information, support each other, and speak for themselves in the public arena. More frequently, people with autism are attending and/or speaking at conferences and workshops on autism. Individuals with autism are providing valuable insight into the challenges of this disability by publishing articles and books and appearing in television specials about themselves and their disabilities.

About the Autism Society of America:
Founded in 1965 by a small group of parents, the Autism Society of America (ASA) continues to be the leading source of information and referral on autism and the largest collective voice representing the autism community for more than 33 years. Today, more than 24,000 members are connected through a volunteer network of over 200 chapters across the United States.

The mission of the Autism Society of America is to promote lifelong access and opportunities for persons within the autism spectrum and their families, to be fully included, participating members of their communities through advocacy, public awareness, education, and research related to autism. In addition to its volunteer Board of Directors, composed primarily of parents of individuals with autism, the ASA has a Panel of Professional Advisors, comprised of nationally known and respected professionals who provide expertise and guidance to the Society on a volunteer basis.

The ASA is dedicated to increasing public awareness about autism and the day-to-day issues faced by individuals with autism, their families, and the professionals with whom they interact. The Society and its chapters share common goals of providing information and education, supporting research, and advocating for programs and services for the autism community.

The ASA Foundation
The Autism Society of America Foundation (ASAF) was founded with the primary mission to raise and allocate funds for research to address the many unanswered questions about autism. We are still far from fully understanding autism and knowing how to prevent it.

The ASAF has implemented action on several pressing autism research priorities as areas of initial focus: developing and publicizing up-to-date prevalence statistics; quantifying the societal and family economic consequences of autism; developing a national registry of individuals and families with autism who are willing to participate in research studies; and implementing a system to identify potential donors of autism brain tissue for research purposes and facilitating the donation process. In addition, the Foundation is contributing substantial funds for applied and biomedical research in the causes of and treatment approaches to autism.
