Clinical information for all patients with psychogenic tremor confirmed by our Movement Disorders Neurophysiology Laboratory (2003\u20132004) was reviewed. A follow\u2010up questionnaire was administered to all included patients in 2007. Psychogenic tremor was documented in 62 patients; 33 responded to the questionnaire (53%). Median onset\u2010age was 50 years (range, 15\u201371); 23 were female (70%). Clinical certainty of psychogenic etiology was: definite, 8 (24%); probable, 16 (49%), and possible, 9 (27%). Characteristic electrodiagnostic features of psychogenic tremor were documented in all. All but two patients were ultimately given a definite diagnosis of psychogenic tremor; recommended psychiatric consultation was only done by 12 (36%). Twenty\u2010one patients (64%) rated tremor disability as moderate or severe after a median follow\u2010up of 5.1 years (range, 3.3\u201319). Improvement occurred spontaneously in 5 (15%), and after a specific intervention in 4 (12%), whereas 3 (9%) had mild but unchanged symptoms. The mean duration of symptoms, prior to diagnosis with psychogenic tremor, was significantly shorter for patients with mild or no tremor at follow\u2010up (<jats:italic>P<\/jats:italic> = 0.037). Physiologically\u2010confirmed psychogenic tremor carries a poor prognosis, with unremitting or worse tremor persisting 3\u2010years after diagnosis in most. \u00a9 2008 Movement Disorder Society<\/jats:p>","DOI":"10.1002\/mds.22301","type":"journal-article","created":{"date-parts":[[2008,10,2]],"date-time":"2008-10-02T18:01:22Z","timestamp":1222970482000},"page":"72-76","source":"Crossref","is-referenced-by-count":51,"title":["Psychogenic tremor: Long term prognosis in patients with electrophysiologically\u2010confirmed disease"],"prefix":"10.1002","volume":"24","author":[{"given":"Andrew","family":"McKeon","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"J.
