A total of 21 patients with psychogenic tremor (PT) were asked to take part in a neurologic and psychosomatic assessment; for 17 patients follow-up information was also recorded. Women out-numbered men in the sample. In the majority of patients the tremor was associated with a variety of other conversion symptoms. The clinical picture of the tremor varied. After beginning exclusively in the extremities, it tended to spread to other parts of the body. Other psychopathology (depression and histrionic personality disorder) existed in almost a third of the sample. Many patients had retired from professional life, or planned to do so in the near future, because of PT. At follow up the initial diagnosis was confirmed in all patients although in some patients additional physical illness had developed during the follow-up period. When neurological and psychiatric/psychosomatic criteria are applied the diagnosis of PT can be established reliably. Studies that have questioned the validity of the conversion concept on the basis of frequent misdiagnoses may indicate problems in the diagnostic procedure rather than an invalid theoretical construct.
