According to the National Institute of Neurological Disorders and Stroke, over 40 million Americans suffer from a chronic sleep disorder. I dare say a fair percentage of them are probably fibromyalgia patients. In addition to pain and fatigue, sleep dysfunction is one of the primary symptoms of fibromyalgia. More than 75% of people diagnosed with FM have difficulty falling asleep, staying asleep and/or awakening from sleep feeling rested and refreshed. In studies where healthy people were deprived of sleep, they developed many of the symptoms of fibromyalgia. That raises a chicken-or-egg-type of question – does fibromyalgia cause a sleep disorder or does a sleep disorder lead to fibromyalgia? No one really knows the answer, but we can be pretty sure that a lack of quality sleep is at least a significant contributing factor to many fibromyalgia symptoms.

Sleep Disorders vary in nature and degree. The three major sleep disorders are dyssomnias ( insomnia ), hypersomnia (disorders of excessive sleepiness) and parasomnias (abnormal behaviors during sleep).

Sleep is a cyclic phenomenon, with four or five REM periods during the night, which accounts for about 25 percent of the total night’s sleep. Examples Of Sleep Disorders Insomnia Insomnia, the sense of not getting enough sleep to awake refreshed, affects 20 to 40 percent of all adults in the course of any year. Although insomnia has myriad causes, it can roughly be divided into three categories: predisposing, precipitating and perpetuating. Predisposing factors are the built-in characteristics of a person that make him or her vulnerable. Tense or driven people whose heads are brimming with plans or worries can easily lose sleep. Others with severe depressio...
Irregular sleep-wake syndrome is sleeping without any real schedule.
Sleep-wake syndrome - irregular
Causes, incidence, and risk factors
Some people have an irregular sleep-wake pattern because of a problem with brain function, the body's internal clock (circadian pacemaker), or other reasons.
This disorder is very uncommon. It typically occurs in someone with a brain dysfunction who does not have a regular routine during the day. The amount of total sleep time is normal, but the body clock loses its normal circadian cycle.
Similar symptoms may be seen in people who have frequently changing work shifts and in travelers who often change time zones. These people have a different condition, such as shift work sleep disorder or jet lag syndrome.
