Psychogenic pain, disturbances of gait and stance, sensory symptoms, dizziness, and psychogenic seizures have been found to be the most common conversion symptoms in neurology clinics. A retrospective analysis of 18 patients suffering from pseudoseizure ''status'' is presented in this study. All of the patients fulfilled the DSM-III-R criteria of conversion disorder, However, 5 of them had concomitant major depression, 6 suffered from bulimia nervosa, and 7 met the criteria for substance abuse. On Axis II, 10 cases of borderline personality disorder, 2 cases of antisocial personality disorder, and 3 cases of histrionic personality disorder were diagnosed. The majority of the patients had attempted suicide and other forms of self-destructive behavior. The findings suggest that patients with pseudoseizure ''status'' suffer from severe affective imbalances and disturbed impulse control. (C) 1997 Elsevier Science Inc.
