Autism is determined by observed behaviors. Medical tests are used to rule out or identify possible underlying problems. Diagnosis can be made using behavior checklists, early developmental history, and parent reports. Autism can occur alone or with other disorders such as mental retardation or epilepsy. The number of handicaps and degree of mental retardation will determine the severity of autism.
Studies show that individuals with autism can improve significantly with appropriate intervention.
As they learn to understand their world, individuals with autism can become more responsive and active with others. Structured programs that emphasize individual instruction work best with individuals with autism. Many can learn to function at home as well as in the community. Many enjoy the same recreational activities as non-handicapped persons. Most enjoy predictable play that they are able to control.
