Neurological syndromes in factitious disorder.
Factitious disorder is characterized by the intentional feigning of physical or psychological signs and symptoms. The best known type of factitious disorder, Munchausen syndrome, is marked by a chronic unremitting course with repeated hospitalizations. The purpose of this study was to assess the frequency, psychopathological phenomenology, and diagnostic classification according to DSM-III-R in patients with factitious disorder presenting as neurological syndromes. We prospectively included all patients who were hospitalized at our Department of Neurology, Freie Universität Berlin, during a 1-year period. Five of 1538 (.3%) patients were diagnosed as having factitious disorder with feigning of neurological syndromes. Four presented with the classic variant, Munchausen syndrome. All patients had similar, characteristic psychopathological features including self-discharge, aggressive behavior, pseudologia phantastica, and hospital wandering. In these cases the additional diagnosis of personality disorder was made according to DSM-III-R criteria. We concluded that factitious disorder presenting with neurological syndromes may be more prevalent than generally assumed. Our findings confirm the idea of frequent coincidence of factitious and personality disorders.
