Polysomnographic findings in dementia with Lewy bodies.

Introduction: The clinical features of dementia with Lewy bodies (DLB) during wakefulness are well known. Other than rapid eye movement (REM) sleep behavior disorder, only limited data exists on other sleep disturbances and disorders in DLB. We sought to characterize the polysomnographic (PSG) findings in a series of DLB patients with sleep-related complaints.
