Several existing techniques for diagnosing psychiatric illness in the presence of physical complaints are faulty. Psychiatric illness may affect only as few as 30% of patients with fibromyalgia in some series. Selection bias overemphasizes the contribution of psychiatric illness to fibromyalgic. Much of that illness will be secondary to pain and disability. Some fibromyalgia disturbances can arise through insomnia and anxiety. Principles in the classification of fibromyalgia are discussed.

The use of tricyclic antidepressants as opposed to hypnotics in treating insomnia is reviewed. Available data indicate that TCAs alleviate sleep disturbances related to depression (often before antidepressant effects are seen) and, in selected cases, may prove effective in disturbed sleep related to sleep apnea, fibrositis, and sleep related bruxism, as well as in adults with childhood onset insomnia or a history of hyperkinesis. However, TCAs share many of the problems reported for hypnotics, as well as having some potentially serious side effects not present with benzodiazepines. The need for determination of the etiology of sleep disorders, and specific pharmacotherapy directed toward identified causes rather than the symptom of insomnia, is stressed.

Fibromyalgia syndrome (FMS) affects predominantly females and is characterised by widespread musculoskeletal pain, fatigue, insomnia, nonrefreshing sleep, diffuse stiffness and other organic and psychic signs and symptoms. Diagnosis is essentially based on the 1990 American College of Rheumatology Classificative Criteria, but if, in some cases, they are not completely fulfilled, diagnosis is not excluded in a particular patient. The causes of the enhanced pain perception and of all the other clinical characteristics are unknown. Both the central hypothesis (sleep disturbance; psychological affection; hypothalamus-hypophysis-adrenal axis disorder; neuromediators disregulation; etc.) and the peripheral theory (anatomical and/or functional muscle disturbance) try to explain FMS etiopathogenesis. Tricycles antidepressants (i.e. amitriptilin) and some muscle relaxants (i.e. ciclobenzaprine) have demonstrated some beneficial effect contrary to the classic antirheumatic drugs (NSAID; corticosteroids; etc.). Physical exercise, multidisciplinary support (behavioural therapy, physical agents; etc.) and patient education are some of the other approaches which contribute to the correct management of FMS.

The relationship between headaches and sleep disturbances is complex and difficult to analyze. Both symptoms may have causal relations, or may be associated in the same patient with mutual reinforcements. We studied 25 patients presenting with morning or nocturnal headaches. Standard headache diagnosis and polysomnography were performed. After polysomnography, the diagnoses were reevaluated. The main headache entities were cluster, chronic paroxysmal hemicrania, migraine, tension, combined headache, and chronic substance abuse headache. For each group, headache, sleep data, and changes in diagnosis are discussed. The diagnosis was changed in 13 patients; the final diagnoses were periodic movements of sleep, fibromyalgia syndrome, and obstructive sleep apnea. The diagnoses of cluster headache and chronic paroxysmal hemicrania were not modified by polysomnography. The migraine and tension headache groups had a relative male preponderance, and the diagnosis was changed in approximately half of the patients. This was also observed in combined headaches. Patients who had chronic substance abuse headaches had mainly insomnia, which in some cases, was relieved by stopping medication. Data were also analyzed in terms of simple models linking headache and sleep disturbances. Such an approach allowed the identification of several modes of mutual interaction. In summary, morning or nocturnal headaches are frequent indicators of a sleep disturbance and their presence might justify polysomnography, and the use of simple clinical models may be useful for understanding the complex relationship between headache and sleep.

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.

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.

5-Hydroxytryptophan (5-HTP) is the intermediate metabolite of the essential amino acid L-tryptophan (LT) in the biosynthesis of serotonin. Intestinal absorption of 5-HTP does not require the presence of a transport molecule, and is not affected by the presence of other amino acids; therefore it may be taken with meals without reducing its effectiveness. Unlike LT, 5-HTP cannot be shunted into niacin or protein production. Therapeutic use of 5-HTP bypasses the conversion of LT into 5-HTP by the enzyme tryptophan hydroxylase, which is the rate-limiting step in the synthesis of serotonin. 5-HTP is well absorbed from an oral dose, with about 70 percent ending up in the bloodstream. It easily crosses the blood-brain barrier and effectively increases central nervous system (CNS) synthesis of serotonin. In the CNS, serotonin levels have been implicated in the regulation of sleep, depression, anxiety, aggression, appetite, temperature, sexual behaviour, and pain sensation. Therapeutic administration of 5-HTP has been shown to be effective in treating a wide variety of conditions, including depression, fibromyalgia, binge eating associated with obesity, chronic headaches, and insomnia.

Fibromyalgia syndrome is a musculoskeletal pain and fatigue disorder manifested by diffuse myalgia, localized areas of tenderness, fatigue, lowered pain thresholds, and nonrestorative sleep. Evidence from multiple sources support the concept of decreased flux through the serotonin pathway in fibromyalgia patients. Serotonin substrate supplementation, via L-tryptophan or 5-hydroxytryptophan (5-HTP), has been shown to improve symptoms of depression, anxiety, insomnia and somatic pains in a variety of patient cohorts. Identification of low serum tryptophan and serotonin levels may be a simple way to identify persons who will respond well to this approach.

We report on a patient who had taken the centrally acting analgesic tramadol for over 1 year. The compound had proven to be sufficient to treat her painful episodes related to fibromyalgia. Due to lack of supply while being on a trip, intake of the drug was stopped abruptly, resulting in the development of classical abstinence-like symptoms within 1 week. Abstinence-like symptoms consisted of restlessness and insomnia for which the benzodiazepine lorazepam was given. Diarrhoea and abdominal cramps were treated with the peripherally active opioid loperamide, while bouts of cephalgia were treated with sumatriptan. Diffuse musculoskeletal-related pain and restless leg syndrome (RLS) were treated with dextromethorphan. All these different medications proved to be efficacious as they resulted in the cessation of symptoms. Within 1 week symptoms ceased and the patient regained her normal activities without any sequelae. Although tramadol is considered a non-habit- and non-dependence-forming analgesic, abstinence symptoms are likely to develop following abrupt cessation of intake, especially when the compound had been taken over 1 year. Therefore patients should be advised of such an effect whenever they decide to stop intake or their physician is planning to switch to another medication. To avoid abstinence-like symptoms doses should be slowly tapered down.

Fibromyalgia is an extremely common chronic condition that can be challenging to manage. Although the etiology remains unclear, characteristic alterations in the pattern of sleep and changes in neuroendocrine transmitters such as serotonin, substance P, growth hormone and cortisol suggest that dysregulation of the autonomic and neuroendocrine system appears to be the basis of the syndrome. The diagnosis is clinical and is characterized by widespread pain, tender points and, commonly, comorbid conditions such as chronic fatigue, insomnia and depression. Treatment is largely empiric, although experience and small clinical studies have proved the efficacy of low-dose antidepressant therapy and exercise. Other less well-studied measures, such as acupuncture, also appear to be helpful. Management relies heavily on the physician's supportive counseling skills and willingness to try novel strategies in refractory cases.
