The Non-REM (NREM) sleep is commonly associated with which of the following?
Night terrors
Frequent dreaming
Frequent penile erections
Increased blood pressure
Night terror (pavor nocturnes), occurs primarily in young children during the first several hours after sleep onset, in slow-wave sleep (NREM stage 3, 4 sleep). In this, the child suddenly screams exhibiting autonomic arousal with sweating, tachycardia, and hyperventilation. It is difficult to arouse children and they rarely recalls the episode on awakening in the morning. Ref: Poh Pathophysiology: Concepts of Altered Health States By Ruth A.
