Background: While sleep disturbances in Parkinson disease (PD) used to be underdiagnosed, they have received greater recognition more recently. Objective is to address types of sleep disturbances in non demented PD patients by using Parkinson Disease Sleep Scale (PDSS) and polysomnography Methods: This study included 24 patients with PD and 10 healthy control subjects. All the participants underwent neurological evaluation including Unified Parkinson disease scale (UPDRS), Parkinson’s disease sleep scale (PDSS) and overnight polysomnographic (PSG) record. Results: Sleep disturbances detected by PDSS and PSG, were significantly more common in PD patients than the control subjects. These disturbances are correlated significantly with the disease duration, severity, and L-dopa dose and duration. Also, these sleep abnormalities are significantly more common in non-tremor (akinetic rigid) subtype of PD. Conclusion: Understanding sleep problems in PD patients will help to improve management of PD patients and improve quality of life in these patients.
