Polygraphic analysis of sleep and wakefulness in patients with Parkinson's syndrome.

The present work is an analysis of 30 patients with Parkinsonian syndrome and 10 healthy persons during different functional states (aroused wakefulness, relaxed waking state, various phases and stages of nocturnal sleep, hypnosis). By means of polygraphic recordings and the Minnesota Multiphasic Personality Inventory (MMPI) it has been shown that motor, emotional and autonomic activity during sleep as well as EEG changes in parkinsonism are uniformly related to the nature and extent of the pathologic alterations in the non-specific, predominantly activating brain systems.
