We report a patient with torsion dystonia whose polysomnographic recordings revealed poor sleep and a pronounced and almost continuous type of spindle activity during non-rapid eye movement sleep. Rapid eye movement sleep was also reduced. These changes proved to be independent of medications. After a clinically successful unilateral thalamic operation, a normalization of sleep parameters and a reduction of the high amplitude sleep spindles was observed. implying that the regulation of sleep spindles and the advancement of dystonic symptoms are affected by a common mechanism.
