The authors studied the records of 84 patients who had idiopathic torsion dystonia. Thirty-seven cases had originally been misdiagnosed as primarily psychiatric illness. Only 1 patient presented with dystonic movements that were clearly part of a more general psychiatric disorder. The authors believe her to be the first reported patient whose dystonia is undeniably of psychogenic origin.
