REM behaviour disorder:

Question

Quizplus · Accepted Answer

REM behavior disorder results when the mechanisms that inhibit the voluntary muscles fail during the REM stage of sleep, leading to physical movements and potentially harmful behaviors. It is not necessarily associated with anxiety or sleepwalking and has not been consistently linked to genetic inheritance or demographics such as age or gender. While there have been rare cases of violence during episodes of REM behavior disorder, it is not a typical outcome.
