REM sleep behaviour disorder

Reading time: 1 min

This is characterised by vigorous motor behaviour during sleep, nightmares or a lack of muscle relaxation during REM sleep. It mainly affects men over 50 years of age.

The diagnosis is made by inspecting a polysomnogram during the REM phase when the patient speaks, screams, is startled, punches or kicks.

In many cases, REM sleep behaviour disorder is the first manifestation of a neurodegenerative disease, such as Parkinson's disease, multiple system atrophy or dementia with Lewy bodies (abnormal deposits of alpha-Synuclein protein).
