Dissociative or psychogenic nonepileptic seizures (PNES) are involuntary episodes of movement, sensation, or behaviors (vocalizations, crying, and other expressions of emotion) that do not result from abnormal brain discharges. The seizures can look like any kind of epileptic seizure. They are somatic manifestations (physical symptoms) of psychologic distress. Psychiatric conditions associated with PNES include depression, anxiety, somatoform disorder, posttraumatic stress disorder, dissociative disorder, and personality disorders. Treatment depends on the cause of the psychologic distress, and may involve cognitive behavioral therapy or psychotherapy, as well as antidepressive medication.
