title: Associations of sleep disturbance symptoms with health-related quality of life in Parkinson's disease.
abstract: The authors examined associations of various sleep-disturbance symptoms with health-related quality of life (HRQOL) in 153 adults with Parkinson's disease (PD). PD patients reported more snoring, sleep inadequacy, daytime somnolence, and sleep-maintenance problems than the general population. Symptoms having the broadest and strongest unique associations with generic HRQOL (eight scales; two composites of SF-36) were daytime somnolence (five scales; one composite), sleep initiation (eight scales; two composites), and awakening short of breath or with headache (six scales; two composites). Associations of selected sleep-disturbance symptoms--some unanticipated--suggest that assessing specific symptoms is worthwhile in clinical care.
