Other Disorders

Other Sleep Disorders

Periodic Limb Movement Disorder (PLMD)

A condition in which a person’s legs or arms twitch or move involuntarily and periodically during sleep.

***PLMD is not the same as night muscle spasms, or hypnic jerks, which are normal and occasionally occur when a person is falling asleep.


Hypnagogic Hallucinations and Sleep Paralysis

Hypnagogic hallucinations and sleep paralysis can occur together and are commonly seen in people with narcolepsy or who are sleep-deprived.

Hypnagogic Hallucinations Defined: Brief periods of dreaming between the stages of sleep and consciousness. These dreams can be frightening and can often cause a sudden jerk and arousal just before sleep onset.

Sleep Paralysis Defined: The sensation of feeling paralyzed upon awakening, usually immediately following a dream. This is commonly associated with the loss of muscle tone during dreams.


Nocturnal seizures

Defined: Nocturnal seizures are usually tonic/clonic (grand mal).

Tonic phase: Muscles will stiffen.

Clonic phase: Extremities will jerk and twitch. Bladder control may be lost. Consciousness is then regained slowly. These seizures might occur just after a person has fallen asleep, just before waking, during daytime sleep, or while in a state of drowsiness.

Do people have seizures while they are asleep?

Nocturnal seizures are very uncommon. The majority of people with nocturnal seizures have idiopathic epilepsy.

Effects: People who experience nocturnal seizures may find it difficult to wake up or to stay awake. Although unaware of having had a seizure while asleep, they may arise with a headache, have temper tantrums, or display other destructive behavior throughout the day.


REM Behavior Disorder

REM Behavior Disorder defined: the ability to act out your dreams.

What happens during sleep? All body muscles, with the exception of those used in breathing, are usually paralyzed during REM (dream) sleep. Behavior such as this can be violent and result in serious injuries to the victim and bed-partner. After awakening the sleeper will usually be able to recall vivid dreaming.



Bruxism defined: Grinding, gnashing or clenching your teeth during sleep or situations that make you feel anxious or tense.

When does this occur? Most often in the early part of the night and can disturb sleep partners.

Did You Know? Some people brux so loudly that they can’t duplicate the sound while awake or relaxed. Others make no sound while bruxing and often deny having the condition even after tooth or jaw damage is discovered.


Rhythmic-Movement Disorder

Rhythmic-Movement Disorder defined: Recurrent head banging, head rolling, or body rocking that occurs just before sleep begins or during sleep. Other behaviors associated with RMD is moaning or humming during these movements.

What age group is this most common in? RMD is seen most often in younger children, yet can also occur in adults.

My sales job requires me to drive all over the state. I used to get so tired around 2 or 3 in the afternoon that I’d have to pull over and take a nap. My work suffered, and I worried about falling asleep at the wheel. It turned out I had sleep apnea. Now I use a CPAP machine while I sleep, and it’s made all the difference. I don’t feel like I’m going to fall asleep while driving and I’m a lot more productive at my job.

Bob K.

I had to force myself to stay active at my job just so I wouldn’t fall asleep. After work, I’d fall asleep in front of the TV. I never had energy, no matter how much I slept. After my sleep study at the Sleep Wellness Institute, my doctor recommended I use a CPAP machine at night. The treatment turned my life around. I’m in bed less but feel more rested, my blood pressure is lower, and the problems with my ulcerative colitis went away.

I knew I snored a lot but I didn’t realize it was a big deal. I learned I stopped breathing 11 times in the night after I did a sleep study. Scary but at least they could help.
