#In addition to sleep apnea, there are a number of significant sleep disorders that might disrupt your healthy sleeping pattern, many of which interact with your sleep apnea diagnosis and treatment. Some of these disorders are:

  • Hypopnea
  • Snoring
  • Bruxism
  • Insomnia
  • Fibromyalgia
  • Narcolepsy
  • Periodic movement in sleep / Restless leg syndrome


Hypopnea is shallow or slow breathing during sleep. If you suffer from hypopnea, you will experience episodes of underbreathing, or long periods of diminished oxygen saturation in your blood. This condition does not represent a complete blockage of the airways. Often sufferers of sleep apnea also suffer hypopnea, and, since both conditions cause similar health difficulties, can experience even more pronounced effects.


The majority of people who suffer from obstructive sleep apnea, also snore. The sound of turbulent airflow through nasal passages can disrupt the sleep of co sleepers whether in the same room or an adjacent room. If you are a snorer, you should be evaluated to see if you suffer from sleep apnea. Consult our Snoring page for more information.


Bruxism is generally known by its more common name: tooth grinding. It usually occurs during sleep, and is often the result of malocclusion, or bad bite, and its attendant condition, temporomandibular joint disorder (TMD), in which the muscles, nerves, and tendons of your jaw joint are stressed. On average, Bruxism occurs 25 times per night, in episodes lasting four to five seconds. The most serious effect of bruxism is serious damage to tooth enamel, including cracking, scraping, grinding. In addition, Bruxism can lead to numerous awakenings during the night, making it another significant disrupter of healthy sleep patterns.


Insomnia is one of the most commonly-known sleep disorders, partly because its symptoms are so visible. When you have difficulty falling asleep, you and others are more aware of the condition than you are of symptoms occurring during sleep. Insomnia is classified as being either onset insomnia, where people have difficulty falling asleep and maintenance insomnia where people have difficulty remaining asleep. For some people, maintenance insomnia may actually be sleep apnea.


Fibromyalgia is a disorder that causes chronic muscle and bone soreness, pain and stiffness, fatigue, and difficulty sleeping. Sufferers report varying pain in the back, shoulders, neck, hands, legs, and other parts of the body. Pain is either of a shooting variety or a sore throbbing. The fatigue may be so severe as to prevent sufferers from working or engaging in any number of activities. It is often experienced in conjunction with other sleep disorders and must be treated simultaneously to achieve good results.


Narcolepsy is a condition in which a person spontaneously falls asleep without control. Patients may or may not experience excessive daytime sleepiness, and the sleepiness is often independent of night sleep. Narcoleptic patients may fall asleep at any time or during any activity, and some may experience loss of muscle function, sleep paralysis, and sleep hallucinations.

Periodic Movement in Sleep / Restless Leg Syndrome

Periodic Movement in Sleep (PMS) occurs when a sufferer experiences unusual sensations in the arms and legs, and may include tingling or itching, and these sensations may lead to unprompted movement. Sometimes referred to as Restless Leg Syndrome (RLS), PMS is a neurological disorder. The condition is not limited to sleep, but is often suffered during the evening hours or any time when the sufferer is inactive. In particular, PMS/RLS can contribute to onset insomnia.

Sleep apnea is defined as the cessation of breathing during sleep for at least 10 seconds, and at least 5 times in an hour.
