AP PSYCHOLOGY

Detailed explanation-1: -Rapid eye movement (REM) sleep behavior disorder is a sleep disorder in which you physically act out vivid, often unpleasant dreams with vocal sounds and sudden, often violent arm and leg movements during REM sleep-sometimes called dream-enacting behavior.

Detailed explanation-2: -REM sleep behavior disorder (RBD) is a sleep disorder in which you physically act out your dreams unknowingly while you’re asleep. The movements involved in RBD can cause injury to you or your bed partner, especially if you’re acting out a violent nightmare. It’s important to seek treatment because of this.

Detailed explanation-3: -Causes of REM Sleep Disorder The exact cause of RBD is unknown, but it may happen along with degenerative neurological conditions such as Parkinson’s disease, multisystem atrophy (also known as Shy-Drager syndrome), and diffuse Lewy body dementia.

Detailed explanation-4: -Subjects awakened from REM sleep recall elaborate, vivid, hallucinogenic and emotional dreams, whereas subjects awakened during non-REM sleep report fewer dreams, which, when they occur, are more conceptual, less vivid and less emotion-laden.

Detailed explanation-5: -REM sleep first occurs about 90 minutes after falling asleep. Your eyes move rapidly from side to side behind closed eyelids. Mixed frequency brain wave activity becomes closer to that seen in wakefulness.
