title: Sleep disturbances and Parkinson's disease.
abstract: Although Parkinson's disease is defined by its motor symptoms, the symptoms that are most devastating to patients and caregivers are dementia and psychosis. In addition, sleep has a tremendous impact on patient well being and quality of life. Eighty percent to 90% of Parkinson's disease patients have a sleep disorder affecting their ability to fall asleep, ability to stay asleep, dreams, motor activity during sleep, post-sleep behavior, or daytime somnolence. Treatment plans for patients with Parkinson's disease who experience sleep disorders aim to improve nighttime sleep or daytime wakefulness, and treatment options vary by sleep disorder.
