Objective: To test the usefulness of the Parkinson's disease sleep scale (PDSS) in identifying sleep disorders in the clinical practice setting.
Methods: Sixty-two PD patients were evaluated with the PDSS and the Epworth sleepiness scale (ESS). A cut-off of less than five for each PDSS item as an indicator of substantial sleep disturbance was chosen.
