Nrem Sleep

Back

Nrem (non-rapid eye movement) sleep is dreamless sleep. Duringnrem, the brain waves on the electroencephalographic (eeg) recording are typically slow and of high voltage, the breathing and heart rate are slow and regular, the blood pressure is low, and the sleeper is relatively still.

SYMPTOMS

Normal sleep has 2 distinct states: non-rapid eye movement (nrem) and rapid eye movement (rem) sleep. Nrem sleep is further subdivided into 3 stages. During rem sleep, rapid eye movements occur, breathing becomes moreirregular, blood pressure rises, and there is loss of muscle tone (relativeparalysis).

CAUSES

Non-rapid eye movement (nrem) sleep arousal disorders. ... They occur during slow wave sleep (sws). NREM Sleep arousal disorders are usually not causedby underlying conditions, and are typically treatable1. NREM Sleep arousal disorders include confusional arousals, sleep-walking, sleep terrors, and sleep sex.
