Diagnosis of dystonia—a syndrome of abnormal, involuntary movements—is difficult, given that many different underlying etiologies exist. Bertram and Williams review studies that investigated etiology in patients with various dystonic syndromes. On the basis of these data, the authors present an eight-question diagnostic approach that should enable both specialists and general neurologists to determine the appropriate diagnostic test for patients with a possible dystonic syndrome.
