Fibromyalgia presents with generalized body pain, multiple tender points, and associated ancillary symptoms, including fatigue and nonrestorative sleep. The abnormal sleep pattern is the most common accepted etiology for this condition. The diagnosis may be made on the basis of a classic presentation of symptoms and clinical findings. The treatment of fibromyalgia includes aerobic exercise and the use of tricyclic antidepressants to modulate the sleep disorder with less than excellent results. In spite of the frustrations in treating this condition successfully, many patients are relieved to be provided with a diagnosis and to obtain sympathetic and supportive care from their physicians.

Various research studies show that the amalgam of disordered sleep physiology, chronic fatigue, diffuse myalgia, and cognitive and behavioural symptoms constitutes a non-restorative sleep syndrome that may follow a febrile illness, as in the chronic fatigue syndrome. Where rheumatic complaints are prominent such a constellation of disturbed sleep physiology and symptoms also characterizes the fibromyalgia disorder. In contrast to the chronic fatigue syndrome, fibromyalgia is associated with a variety of initiating or perpetuating factors such as psychologically distressing events, primary sleep disorders (e.g. sleep apnoea, periodic limb movement disorder) and inflammatory rheumatic disease, as well as an acute febrile illness. The chronic fatigue syndrome and fibromyalgia have similar disordered sleep physiology, namely an alpha rhythm disturbance (7.5-11 Hz) in the electroencephalogram (EEG) within non-rapid eye movement (NREM) sleep that accompanies increased nocturnal vigilance and light, unrefreshing sleep. Aspects of cytokine and cellular immune functions are shown to be related to the sleep-wake system. The evidence suggests a reciprocal relationship of the immune and sleep-wake systems. Interference either with the immune system (e.g. by a viral agent or by cytokines such as alpha-interferon or interleukin 2) or with the sleeping-waking brain system (e.g. by sleep deprivation) has effects on the other system and will be accompanied by the symptoms of the chronic fatigue syndrome.

There is a general tendency to restrict the notion of sleep disorders to insomnia and consequently to limit treatment to the prescription of hypnotics. However, it is very often of benefit to prescribe psychotropic agents, in particular antidepressants, not only in insomnia but also in certain cases of hypersomnia, parasomnia and dysomnia associated with organic diseases. In some conditions, however, antidepressants may either induce or aggravate sleep disorders. This is the case with a number of psychostimulants that occasionally induce insomnia. It is also true of the tricyclic antidepressants, which may worsen or even induce a restlessleg syndrome that is often associated with periodic movement syndrome. On the other hand, the antidepressants may play a therapeutic role in certain sleep disorders : - depression-related insomnia is of course the << primary >> indication for antidepressants. Furthermore, certain antidepressants exhibit a sedative action resulting in a hypnogenic-type effect which appears well before the antidepressant effect; - the other types of insomnia may also often be treated with antidepressants : not acute reactional insomnia, against which hypnotics are remarkably effective, but chronic insomnia. In addition, all antidepressants may eventually correct depressive hypersomnia, but in these cases, it is evidently preferable to prescribe non-sedative drugs. Although some tricyclic antidepressants have been proposed for use in hypersomnia due to sleep apnea, their therapeutic interest is minor compared with mechanical and surgical treatment. In contrast, antidepressants play an important role in the treatment of narcolepsy, particularly for the correction of attacks of cataplexy. Antidepressants have also been used for some time in the treatment of parasomnia related to slow deep sleep (night terrors and sleepwalking), but the antidepressants may also be used in enuresis and in parasomnia related to REM sleep : nightmares, sleep paralysis, behavioral problems associated with REM sleep. Antidepressant (mainly serotoninergic drugs) are often used in the treatment of fibrolitis syndrome. Finally, antidepressants (particularly the serotoninergic antidepressants) play an important role in the drug treatment of fibromyalgia.

Polysomnographic findings were compared between a group of patients with the chronic fatigue syndrome (CFS; n = 49) and a matched healthy control (HC) group (n = 20). Sleep initiation and sleep maintenance disturbances were observed in the CFS group. The percentage of stage 4 was significantly lower in the CFS group. A discriminant analysis allowed a high level of correct classification of CFS subjects and HC. Sleep-onset latency and the number of stage shifts/hour contributed significantly to the discriminant function. The presence of these anomalies as well as the decrease in stage 4 sleep were not limited to the patients also diagnosed with fibromyalgia or with a psychiatric disorder. No association was found between sleep disorders and the degree of functional status impairment. The mean REM latency and the percentage of subjects with a shortened REM latency were similar in CFS and HC.

Fibromyalgia is a chronic medical condition characterized by widespread body pain and uncontrollable fatigue. It is often accompanied by many other problems such as irritable bowel, headaches, sleep disorder, and poor circulation. Diagnostic criteria including tender point locations and various other symptoms are provided to aid in recognizing fibromyalgia. Treatment options including the latest drug therapies and self-help therapies should assist the health care provider in treating the fibromyalgia patient. The clinician and the patient must work closely together to identify the combination of treatment options and medications that are most beneficial to each patient. Patient education is crucial since patients who understand their medical condition will be better able to manage their symptoms. Through further research and education, an improved quality of life for patients with fibromyalgia and their families can be attained.

Fibromyalgia (FM) patients report early morning awakenings, awakening feeling tired or unrefreshed, insomnia, as well as mood and cognitive disturbances; they may also experience primary sleep disorders including sleep apnea. Longitudinal studies have demonstrated the chronic nature of these disturbances in patients with FM. A distinct relationship exists between poor sleep quality and pain intensity. Polysomnographic findings during sleep in these patients include an alpha frequency rhythm, termed alpha-delta sleep anomaly, which is also seen in normal controls during stage 4 sleep deprivation; deep pain induced during sleep in normal controls also causes this anomaly. Sleep architecture is altered in FM patients showing an increase in stage 1, a reduction in delta sleep, and an increased number of arousals. Before prescribing pharmacologic compounds aimed at modifying sleep, adequate pain control and sleep habits should be achieved; tricyclic antidepressants, trazadone, zopiclone, and selective serotonin reuptake inhibitors, however, may be required. More research is needed to elucidate the cellular and molecular mechanisms involved in the sleep disturbances occurring in patients with FM.

The clinical characteristics of 120 patients with fibromyalgia is reported. Most of the patients were 21-50 years old. More than 56% patients had three chief symptoms: generalized myalgia, abnormal sensations and easily fatigue. 49.2% of the patients complained multiple arthralgia; 29% with sleep disorder and 23% with local myospasm of lower limbs. The trigger point was regarded as an important physical sign. The etiology and differential diagnosis for fibromyalgia were discussed.

For the past 25 years, the 'alpha-delta NREM sleep abnormality' has been used by some as a defining or legitimizing marker for poorly defined rheumatic diseases such as fibromyalgia and chronic fatigue syndrome. Comprehensive review of the literature reveals no support for such a conclusion. Most studies involve small numbers of patients. The lack of control subjects, non-standardized recording techniques, and confusion between tonic and phasic alpha frequency activity patterns make comparison difficult. There is much evidence that this sleep EEG pattern is not only non-specific, but may actually reflect a sleep maintaining process. The 'sleep fragmentation' theory of the complaint of non-restorative sleep in this patient population is invalidated by the fact that conditions characterized by severe sleep fragmentation, such as obstructive sleep apnea, are not associated with musculoskeletal symtoms. It is difficult to attribute musculoskeletal symptoms to disorders of sleep in view of the fact that the only organ of the body known to benefit from sleep, or to be adversely affected by lack of sleep, is the brain. It is concluded that fibromyalgia and chronic fatigue syndrome are associated with subjective sleep complaints, but do not represent sleep disorders.

Fibromyalgia syndrome is a common chronic pain syndrome that is often associated with sleep disturbances characterized by subjective experience of non-restorative sleep. The complaints of sleep disturbances are correlated with polysomnographic features showing clear abnormalities in the continuity of sleep as well as in the sleep architecture. Sleep-recording abnormalities are characterized by a reduced sleep efficiency with increased number of awakenings, a reduced amount of slow wave sleep and an abnormal alpha wave intrusion in non rapid eye movement, termed alpha-delta sleep. These data were confirmed by spectral analysis of sleep showing an increased EEG power density in the higher frequency band and a reduced EEG power density in the lower frequency bands. Moreover, other microstructural aspects of sleep were modified with high frequency of arousals and alpha-K complex reported, both indicators of fragmented sleep. The fibromyalgia symptoms may relate to a non-restorative sleep disorder associated with the alpha-EEG sleep anomalies. However, alpha-EEG sleep anomaly is non-specific for fibrositis, also seen in normal controls during stage 4 sleep deprivation. Moreover, fibromyalgia patients may also experience primary sleep disorder such as sleep apnea or periodic leg movements. The etiology of this common condition is incompletely understood and the existence of a specific entity of fibromyalgia is still a matter of debate. However, several studies have found abnormal brain metabolism of substances such as serotonin implicated in sleep arousal and pain mechanisms and administration of tricyclic antidepressants and selective serotonin reuptake inhibitors may be useful in fibromyalgia. Pain, poor sleep quality and anxiety may contribute to the clinical picture. Several factors such as psychological, environmental, genetic factor, altered serotonin metabolism and altered sleep physiology are involved in the pathogenesis of fibromyalgia.

Biological clock and magnesium status are linked. Central magnesium regulation may be hypothetized. Balanced magnesium status is requested to obtain efficiency of suprachiasmatic nuclei and of pineal gland. Conventional bright light therapy appears as a speedy and efficient antidepressant medication useful for the treatment of various types of depression, and of non migrainous headaches also. Although decrease in melatonin production seems accessory, increases of serotonergy and perhaps of Reactive Oxygen Species constitute the main mechanisms of action. Chromatotherapy emphazizes the effects of short exposure to specific colors. Although the increased production of melatonin constitutes the best marker of darkness, it is only an accessory mechanism of its action. The psycholeptic sedative effects of darkness, like those of magnesium, rely on direct membraneous and oxidant actions, neural mediated effects (i.e. stimulation of inhibitory neuromodulators such as GABA and taurine), and on antagonism of neuroactive gases (CO and NO). Darkness therapyper se, partial substitutive therapy with melatonin and with their mimicking agents (Mg, L-Tryptophan,Taurine) apply to all the chronopathological forms of magnesium depletion with decreased production of melatonin: sleep disorders, migraine, chronic fatigue syndrome, fibromyalgia, some forms of asthma and of sudden infant death syndrome. Further research should assess the importance of the chronopathological forms of magnesium depletion in the physiopathology of these disorders.
