Comments Types of Sleep Disorders Part 2
![]() |
Periodic Limb Movement Disorder (PLMD)
This is a related condition involving involuntary, rhythmic limb movements, either while asleep or when awake. While most people who have Restless Legs Syndrome also have PLMD, only some people with PLMD also have RLS. Because of the discomfort the symptoms cause, RLS can make it difficult falling (and staying) asleep. Alternative therapies, lifestyle changes, and even nutritional supplements have proven helpful for RLS and PLMD sufferers.
Narcolepsy
Narcolepsy is a disorder that causes a person to have difficulty staying awake. Narcolepsy can cause a person to suddenly fall asleep during the day. These “sleep attacks” occur even after getting enough sleep at night. The unusual sleep pattern that people with narcolepsy have can affect their schooling, work, and social life.
Symptoms:
Intermittent, uncontrollable episodes of falling asleep during the daytime
Excessive daytime sleepiness
Sudden, short-lived loss of muscle control during emotional situations
Hallucinations
Sleep paralysis
Nighttime wakefulness
Rapid entry into REM sleep
Night Terrors
Dreaming is a natural part of sleeping, everyone dreams, although some might not recall their dreams. However, sometimes dreams can turn really scary night Terrors. Night terrors occur during slow wave sleep. They cause intense terror and partial arousal. The sleeper may appear to be awake, sitting up, eyes open, but is actuality still asleep. The person seldom remembers the episode or the dream the next
