Sleep Disorder-Night Terrors Disorder

Sleep terrors are classified as a parasomnia — an undesirable behavior or experience during sleep. Sleep terrors are a disorder of arousal, meaning they occur during N3 sleep, the deepest stage of non-rapid eye movement (NREM) sleep.

  • Self-reported developmental changes in the frequency and characteristics of somnambulistic and sleep terror episodes in chronic sleepwalkers
    by Narges Kalantari on January 6, 2022

These findings add to the limited literature in the field and provide valuable insights into how key clinical characteristics of somnambulism evolve across the lifespan.
