Epilepsy applies to numerous nervous system disorders that result in abnormal electrical discharges of brain cells. This produces seizures that may cause convulsive movements, or partial or total loss of consciousness. Only a small percentage of people with epilepsy also have mental retardation. Scientific advances have made it possible to control many forms of epilepsy. As a result, most people with the condition lead normal lives.
Autism is a developmental disorder that limits learning and slows intellectual development.
People with autism have great difficulty relating and responding to persons, events or objects. People who have mild autism have very limited interests. They may demonstrate some repetitive actions and a marked lack of sensitivity to other people. People who have more severe autism have difficulty listening to and communicating with others. Their interactions with people can be confusing or uncertain at best.
