Common Sleep Disorders

During sleep, the body works to:

  • Improve learning, memory, mood and insight
  • Contribute to a healthy immune system
  • Allow respiratory and cardiovascular systems to rest
  • Maintain hormones at healthy levels promoting appetite control, tissue growth and recovery

Here is a list of the most common sleep disorders:


Chronic Sleep Deprivation

Chronic sleep deprivation is the condition of not getting enough sleep, often causing fatigue and daytime sleepiness.

Excessive Daytime Sleepiness

Excessive daytime sleepiness is when an individual experiences a lack of energy and lasting sleepiness throughout the day.


Many individuals have trouble falling asleep, staying asleep or feel that their sleep is not refreshing. Although an occasional night of poor sleep is normal, in our fast paced world, chronic sleep problems are not.


Narcolepsy is a sleep disorder that can cause daily episodes of inappropriate sleepiness (sleep attacks), loss of muscle tone, sleep paralysis and hallucinations. These symptoms can lead to exhaustion and make daily activities difficult.

REM Sleep BehaviorDisorder (RBD)

During Rapid Eye Movement (REM) sleep, a person typically experiences a high level of brain activity, along with irregular breathing, increase in blood pressure and temporary loss of muscle tone (paralysis). REM is commonly associated with dreaming. In instances of a person with RBD, the paralysis that takes place during REM is either shortened or non-existent, allowing a person to physically “act out” their dreams while sleeping. Such behaviors can include, but are not limited to, kicking, yelling and punching. In some instances, RBD can increase the risk for development of Parkinson’s Disease.

Restless Leg Syndrome (RLS)

People with RLS describe unusual feeling in their legs such as creeping, crawling or a pulling sensation. In addition, they may feel the need for leg movement. These sensations range in severity. If left untreated, RLS can cause exhaustion and daytime fatigue, which can interrupt daily work activities. Sleep deprivation, in some cases, can lead to depression.

Sleep Apnea

In adults, loud snoring and daytime sleepiness raise the possibility of underlying sleep apnea. Yet, some individuals with sleep apnea may not snore or feel sleepy. Untreated sleep apnea often increases the risk for development of hypertension, stroke, heart disease, mood disorders, motor vehicle and work-related accidents, and breaches in interpersonal relationships.

Sleep Hygiene

Sleep hygiene refers to the habits that can affect an individual’s ability to get good sleep.


Snoring is a condition where air flow through the mouth and nose is physically obstructed often causing a sound that can affect quality of sleep.
