title: Posttraumatic paroxysmal nocturnal hemidystonia.
abstract: The term "nocturnal paroxysmal dystonia" has been used to describe patients who display paroxysmal episodes of dystonic-dyskinetic movements arising during nonrapid eye movement sleep, in particular stages 2-3 (Lugaresi E, Cirignotta F. Hypnogenic paroxysmal dystonia: epileptic seizure or a new syndrome. Sleep 1981;4: 129-138). The pathogenesis of these attacks has remained controversial. We describe a patient with posttraumatic paroxysmal nocturnal hemidystonia. Acetazolamide led to improvement.
