APA Dictionary of Psychology

an episode that resembles an epileptic seizure but is not produced by an abnormal electrical discharge in the brain. According to the Epilepsy Foundation, such seizures may be classified as physiologic nonepileptic seizures, which are associated with metabolic disturbances (e.g., changes in heart rhythm or sudden drops in blood pressure) and include syncope and transient ischemic attacks, or as psychogenic nonepileptic seizures. Nonepileptic seizures are also called nonepileptic events (or attacks), pseudoseizures, or pseudoepilepsy, although use of the latter two terms is now discouraged.
