title: [Sleep disorders in Steele-Richardson disease. Polygraphic study of 3 cases].
abstract: 24 recordings of night-time sleep in three patients suffering from progressive supranuclear paralysis were carried out. There was observed: a tendency to insomnia, disappearance of spindles, an invasion of slow sleep immediately it appeared by the muscular and ocular criteria of paradoxical sleep, a considerable reduction in paradoxical sleep in the strict sense of the term, the latency of which in making its appearance was, however, maintained; progressive invasion of the paradoxical phases by slow waves. These abnormalities differ from those found in Parkinson's disease.
