Abstract

Background: Sleep disturbances in Parkinson's disease (PD) are common and symptoms can be broadly categorized into insomnia, motor, urinary and neuropsychiatry. However, there are no formal instruments available for quantifying sleep problems in Parkinson's disease.
Methods: We studied 15 items of sleep related symptoms on the Parkinson's disease sleep scale (PDSS) for 50 patients with PD and 50 age healthy matched subjects. Test-retest reliability was assessed in a subgroup of the subjects.
Results: The PD patients group had impaired scores compared with age healthy matched group in PDSS scores. Within the PD group, it was different between the mild and moderate group in PDSS scores. It showed a discriminatory power in all individual items of scale, except item 14 (sleep refreshment). In test retest reliable score, it showed good reliability.
Conclusions: We suggest that PDSS is a simple instrument for evaluating sleep disturbances in PD and it could be used to help targeted treatment strategies for nocturnal problems in PD. KeyWords:Parkinson's disease, Sleep disturbance, Parkinson's disease sleep scale
