[Sleep disorders and Parkinson disease: study of a series]

Disturbances of sleep are frequent and varied in patients with Parkinson's disease. In an attempt to find out about these disturbances, we carried out interviews using the Vanna and Mazzuia questionnaire, modified for forty-five sufferers of Parkinson's disease, and forty healthy adults. We researched sleep habits and disturbances, as well as the consumption of hypnotics. We found that both groups had similar habits, although those with PD altered according to the stage of development of the disease, thus difficulty in staying sleep and parasomnia were more frequent in PD sufferers and worsened in the most advanced cases. On the other hand the quality of night sleep and the consumption of hypnotics interfered in the daytime efficiency of those suffering from Parkinson's Disease.
