Parkinson’s disease sleep scale, sleep logs, and actigraphy in the evaluation of sleep in parkinsonian patients

Year: 2009

Type: article

Abstract: The aim of this study was to compare the results of the day-to-day self-evaluation of sleep quality by sleep logs with Parkinson's disease sleep scale (PDSS) in Parkinson's disease (PD) patients. Actigraphy was used as an independent analysis of nighttime activity interfering with sleep. A total of 71 idiopathic PD patients and 21 age- and sex-matched normal individuals lacking any type of sleep disturbance were recruited. Sleep was evaluated by PDSS, 7-d sleep log and actigraphy. Sleep logs and PDSS showed reduced sleep quality and daytime somnolence scores in moderate/severe PD patients as compared to healthy controls. Significant correlations were found between sleep quality in sleep logs and all domains of PDSS sleep quality, except for the presence of nocturia, which correlated with nocturnal activity. PD severity and depression were the only predictors of reduced sleep quality. The retrospective and day-to-day sleep self-evaluations were coincident. Reduced sleep quality was related to increased PD severity and depression scores.
