Sleep disturbance analysis between Parkinson disease and vascular parkinsonism: PDSS-2 and PSQI based study

Abstract

This study was aimed to compare the sleep disturbances of patients with Parkinson's disease and those with vascular parkinsonism. Analytic study with a case–control approach. Fifteen participants then grouped as Parkinson's disease and vascular parkinsonism and Hoehn and Yahr stage. Sleep disturbances were assessed by Parkinson's Disease Sleep Scale-2 (PDDS-2) and Pittsburgh Sleep Quality Index (PSQI. A t-independent test analyzed data. Among 15 samples, 10 of them were Parkinson's disease, and five others were vascular parkinsonism. PDSS-2 for all participants was concluded to have sleep disturbances. The type of sleep disturbances was found consistent in all study groups. PSQI showed a 100% abnormality in both groups. All statistical analyses for PDSS-2 and PSQI between vascular parkinsonism and Parkinson's disease revealed no significant difference except in PSQI results (p = 0.015) for the mild stage. There were no significant differences found in both groups, Parkinson's disease and vascular parkinsonism.
