Fatigue in chronic migraine patients

Abstract:

Fatigue is a common symptom frequently reported in many disorders including headaches, but little is known about its nature. The objective was to determine the prevalence of fatigue in chronic migraine (CM) patients, to define its subtypes and its relationship with other conditions comorbid with CM. Sixty-three CM patients were analysed. The Fatigue Severity Scale (FSS), the Chalder fatigue scale and the CDC diagnostic criteria for chronic fatigue syndrome (CFS) were used. Fifty-three (84.1%) patients had FSS scores greater than 27. Forty-two (66.7%) patients met the CDC criteria for CFS. Thirty-two patients (50.8%) met the modified CDC criteria (without headache). Beck depression scores correlated with FSS, mental and physical fatigue scores. Trait anxiety scores also correlated with fatigue scales. Women had higher FSS scores than men, P < 0.05. Physical fatigue was associated with fibromyalgia, P < 0.05. Fatigue as a symptom and CFS as a disorder are both common in CM patients. Therapeutic interventions include a graded aerobic exercise program, cognitive behavioural therapy and antidepressants. Identification of fatigue and its subtypes in headache disorders and recognition of headaches in CFS patients has implications for the pathophysiology, diagnosis and treatment of these disorders.

Fibromyalgia and other unexplained clinical conditions

Abstract:

Several unexplained clinical conditions frequently coexist with fibromyalgia; these include chronic fatigue syndrome, irritable bowel syndrome, temporomandibular disorder, tension and migraine headaches, and others. However, only recently have studies directly compared the physiological parameters of these conditions (eg, fibromyalgia vs irritable bowel syndrome) to elucidate underlying pathogenic mechanisms. This review summarizes data from comparative studies and discusses their implications for future research.

Sympathetic nervous system function in fibromyalgia

Abstract:

This review focuses on studies of the sympathetic nervous system in fibromyalgia (FM). First, a brief review of the sympathetic system, and its relationship to the human stress response, is outlined. Then various studies of functional assessment of sympathetic function in FM are highlighted. Certain methods of assessment (eg, heart rate variability, biochemical, and psychophysical responses to various stressors) that we believe to be of specific importance for future research are discussed in greater detail. Finally, findings on autonomic function in related disorders–specifically, chronic fatigue syndrome, irritable bowel syndrome, and migraine–will be briefly presented.

The pathogenesis of chronic pain and fatigue syndromes, with special reference to fibromyalgia

Abstract:

Syndromes characterized by chronic pain and fatigue have been described in the medical literature for centuries. Fibromyalgia is the term currently used to describe this symptom complex, and considerable research has been performed in the last decade to delineate the epidemiology, pathophysiology, and genesis of this entity. Although fibromyalgia is defined by its musculoskeletal features, it is clear that there are a large number of non-musculoskeletal symptoms, such that we now understand that there is considerable overlap with allied conditions such as the chronic fatigue syndrome, migraine and tension headaches, irritable bowel syndrome, and affective disorders. This article will review our current state of knowledge regarding fibromyalgia and these allied conditions, and present a unifying hypothesis that describes both the pathophysiology of symptoms and the genesis of these disorders.

Comorbidity of fibromyalgia with medical and psychiatric disorders

Abstract:

PURPOSE: Patients with fibromyalgia have been reported to display high rates of several concomitant medical and psychiatric disorders, including migraine, irritable bowel syndrome, chronic fatigue syndrome, major depression, and panic disorder. To test further these and other possible associations, we assessed the personal and family histories of a broad range of medical and psychiatric disorders in patients with fibromyalgia.

PATIENTS AND METHODS: Subjects were 33 women (mean age 42.1 years) who each met American College of Rheumatology criteria for fibromyalgia and presented to a rheumatologist at a tertiary referral center. They received the Structured Clinical Interview for DSM-III-R (SCID); a supplemental interview, in SCID format, for other medical and psychiatric disorders, including migraine, irritable bowel syndrome, and chronic fatigue syndrome; and an interview for family history of medical and psychiatric disorders.

RESULTS: Patients with fibromyalgia displayed high lifetime rates of migraine, irritable bowel syndrome, chronic fatigue syndrome, major depression, and panic disorder. They also exhibited high rates of familial major mood disorder.

CONCLUSIONS: The finding that migraine, irritable bowel syndrome, chronic fatigue syndrome, major depression, and panic disorder are frequently comorbid with fibromyalgia is consistent with the hypothesis that these various disorders may share a common physiologic abnormality.
