Polygraphic analysis of sleep in dystonia musculorum deformans.

The functional state of non-specific brain systems was studied in 27 patients with torsion dystonia through a complex of techniques, which included clinical, experimental psychological and electrophysiological examination of night sleep. Changes of involved nature have been identified in the various elements of non-specific systems in different clinical forms of the disease in its early and advanced stages, which allows to consider torsion dystonia as a functional organic psychomotor syndrome in the origination of which a great role belongs to non-specific integrative systems of the brain.
