Fatigue is one of the most common complaints among patients seen in the primary care setting. Chronic fatigue syndrome, which has recently been called chronic fatigue immune dysfunction syndrome, is distinctive, with an abrupt onset of symptoms that wax and wane for at least six months. Usually there is low-grade fever, pharyngitis and tender, but not enlarged, lymph nodes. The fatigue can be disabling and is often made worse by physical activity. Some patients with this disorder have also been found to have highly characteristic immunologic abnormalities. Treatment can be rewarding and is based on patient education and support, exercise and symptomatic therapies for abnormal sleep patterns, musculoskeletal pain and other symptoms.

Ten patients attending one general medical hospital clinic who fulfilled operational criteria for the diagnosis of myalgic encephalomyelitis (ME) and with a history longer than three months, underwent a series of standardized neuropsychological and psychiatric tests. Nine were able to complete the tests and were individually matched with a normal control group for age, sex, educational background and premorbid intelligence. The ME subjects showed inferior performance to the controls on two tests of verbal memory. Their personality scores displayed less extraversion and less psychoticism. This is the first report of objective neuropsychological abnormalities in patients with ME, suggesting a discrete deterioration of short-term memory. The findings may also suggest a concurrent psychiatric component of the condition, but the direction of causality remains to be clarified.

Two-hundred and eight patients with chronic fatigue syndrome (post-viral fatigue syndrome) completed a questionnaire which dealt both with their illness in general and with the extent to which they experienced specific symptoms. A factor analysis of the symptom data yielded four components: emotional distress; fatigue; somatic symptoms; and cognitive difficulty. Emotional disturbance is a common feature of the disorder and its role has been widely debated. When the symptom components were considered independently, fatigue, somatic symptoms and cognitive difficulty were associated with questionnaire items relating to general illness severity, but emotional distress was not. Thus negative emotions did not contribute directly to patients' perception of illness severity. They were, however, correlated with the other symptom components. It is argued that this correlation reflects a reciprocal influence, with negative emotions exacerbating fatigue and other key symptoms and the debilitating nature of these symptoms enhancing emotional vulnerability.

Chronic fatigue syndrome is a chronic debilitating illness that is marked in the majority of cases by sudden onset of fatigue and flulike symptoms. Symptoms subsequently relapse and remit and may persist for years. Physical examination typically reveals relatively minor, nonspecific abnormalities in an apparently well patient. Although immunologic abnormalities are associated with chronic fatigue syndrome, tests for these features are expensive, nonspecific, and generally reserved for research purposes. The diagnosis is made on the basis of new onset of severe fatigue, a characteristic pattern of symptoms, and exclusion of other illnesses. Treatment is aimed at alleviating symptoms and helping patients adjust to the debilitating and chronic nature of the illness.

The state of chronic fatigue syndrome (CFS) as abnormal illness behaviour or as biologically determined disease is undecided. The ensuing, often public, debate has confused the community and has led to sharp differences in the therapeutic approach to individual patients. These challenges are compounded when the patient is an adolescent and intergenerational issues enter the picture. Two adolescent cases with different outcomes are presented and the principles of a rehabilitation approach to treatment are outlined which attempt to avoid being drawn into unproductive debates about aetiology.

During the past year many studies have been published on fibromyalgia and chronic fatigue syndromes. Randomized clinical trials using current operational diagnostic criteria were reported, but no single therapy has been highly effective in either condition. The working case definition of chronic fatigue syndrome has been criticized and suggestions for a new case definition have been made. Further understanding of the overlap of these three common disorders will also require that uniform diagnostic criteria be tested in chronic fatigue syndrome and myofascial pain syndrome.

The chronic fatigue syndrome (CFS) is a poorly understood condition with nonspecific signs and symptoms, especially debilitating fatigue. Most patients can pinpoint the onset of their illness and usually describe a flu-like state. The search for an etiologic agent has focused on a number of viruses such as Epstein-Barr, enteroviruses, retroviruses, and human herpesvirus-6. Evidence supports persistent viral infection in a small percentage of CFS patients. Immunologic abnormalities do exist in CFS, which indicate the presence of immune activation in CFS patients. Although abnormal muscle biopsies have been found in some patients with CFS, strength and endurance appear normal, but perception of exertion may be abnormal. Patients with chronic fatigue have a high incidence of premorbid and concurrent psychiatric disorders, and on physical examination many often have reproducible tender points similar to fibromyalgic patients. Clinical evaluation should rule out other potential causes of fatigue, but elaborate diagnostic tests are seldom required. Presently, no specific treatment exists for CFS. A cognitive behavioral approach with or without the use of tricyclics has been advocated. Patients should be encouraged to maintain functional status and should not be discouraged from exercise. Several medications have been tried but with no definite clinical benefit.

Chronic fatigue syndrome (CFS), which is characterized by devastating fatigue, mild fever, lymphadenopathy, headache, myalgia, insomnia and neuropsychiatric disorders, now has drawn much attentions from many physicians, researchers and even peoples in general society world wide. The pathogenesis of CFS is still remains to be clarified and clinico-pathological difference between CFS and mood disorder is controversial. In this paper, CFS would be reviewed in detail.

Myalgic encephalomyelitis (ME) is a postviral syndrome whose dominant clinical features are exercise-induced muscle fatigue, disturbances in cognitive functioning and symptoms of overactivity of the autonomic nervous system. The syndrome tends to affect previously fit young adults between the ages of 20 and 40 but no age group is excluded. One recent epidemiological survey suggested a prevalence rate of 1.3 per 1000 adults, with females outnumbering males by 1.8:1. ME is currently the subject of intense medical (and media) debate, especially over its pathophysiology and management. It has also become known as the postviral/chronic fatigue syndrome (PVFS/CFS).

Chronic Fatigue Syndrome appears to represent a spectrum of disorders in which a variety of pathophysiological mechanisms may operate. While the initiating event in the majority of patients is a pyrexial illness, possibly due to enterovirus infection, evidence of persisting infection or inflammatory changes in muscle and/or brain remain unconvincing. CFS patients display a definite reduced aerobic work capacity compared to normal control subjects, but this may reflect a state of deconditioning resulting from prolonged physical inactivity. They also have an altered perception of their level of exertion and premorbid fitness. The characteristic fluctuation in symptoms, with periods of relapses and partial remissions, may indicate that some central disorder of sensory perception is operational. It may be that a primary sleep disorder results in a reduced sensory threshold for afferent stimuli from muscle. This could well account for many of the subjective symptoms which patients experience. Much more research is clearly necessary if we are to achieve a better understanding of this distressing and at present enigmatic disorder.
