Outline: Epilepsy is a behavioral manifestation of a brain disturbance that causes synchronous firing of large numbers of neurons. Its incidence in the population and the severity of the disability in millions of individuals makes this a serious health problem worldwide. Diagnosis depends on a careful analysis of the person's behavior and the pattern of neuronal activity in the brain, sometimes supplemented by brain imaging studies. In some individuals, there is no discernible physiological cause of the seizures and a diagnosis of psychogenic seizures will be made, often with the help of someone in the mental health field. Psychologists and social workers often play a role in the choice of treatments and their implementation. Another role of the mental health worker is to point the person with epilepsy or that person's family to groups in the community and national groups that are dedicated to helping persons with this disorder.
