Full Definition
Rapid eye movement density is a polysomnographic parameter that quantifies the frequency of conjugate eye movements during REM sleep periods. Typically expressed as movements per minute of REM sleep, this measure provides insight into REM sleep intensity and may be altered in various psychiatric and neurological conditions. Changes in REM density can indicate treatment effects of medications or progression of sleep-related disorders.
