Dementia with Lewy bodies, sleep behavior disorder, and video-polysomnographic analysis


  • Video-polysomnography (V-PSG) may help diagnose rapid eye movement (REM) sleep behavior disorder (RBD) in dementia with Lewy bodies (DLB).

Why this matters

  • Correctly characterizing sleep disorders will lead to improved diagnostic accuracy as well therapeutic strategies to improve sleep and quality of life in patients with DLB.
