Neurasthenia and Chronic Fatigue: Theory and Practice in Britain and America

The symptoms that make up the construct of neuras thenia, including fatigue and exhaustion, are dimension ally distributed in the community. The decision to create a category called neurasthenia is an arbitrary one, influenced by issues of severity and morbidity. The prevalence and nature of the resulting concept are also substantially influenced by the decision on how to classify the close relationships among excessive fatigue, depression and anxiety. Superimposed upon this classi fication is a second, parallel structure of illness beliefs. The original construct of neurasthenia as a physical disease that resulted from overwork, was of consider able utility to both doctors and patients. This early concept of neurasthenia can be recognized in the modem revival of interest in chronic fatigue syndrome (CFS) in Western cultures. The current highly charged atmosphere surrounding these diagnoses reflects the issues of legitimacy and non-legitimacy in illness, usually expressed in competing physical and psychologi cal explanations of ill health.

Pacing as a strategy to improve energy management in myalgic encephalomyelitis/chronic fatigue syndrome: a consensus document

PURPOSE

Myalgic encephalomyelitis/chronic fatigue syndrome (ME/CFS) is a debilitating condition characterized by a number of symptoms which typically worsen following minimal exertion. Various strategies to manage the limited energy levels have been proposed. Of these, pacing has been consistently rated as one of the most helpful in surveys conducted by patient groups. This review is a response to the paucity of the information on pacing in the scientific literature.

METHOD

We describe the principle of pacing and how this can be adapted to meet individual abilities and preferences. A critical evaluation of the research was conducted to ascertain the benefits and limitations of this strategy.

RESULTS

Based on various studies, it is proposed that pacing can help to stabilize the condition and avoid post-exertional malaise.

CONCLUSION

Pacing offers practitioners an additional therapeutic option which is acceptable to the majority of patients and can reduce the severity of the exertion-related symptoms of ME/CFS.

Illness Intrusiveness in Myalgic Encephalomyelitis

This study assessed the relationship between illness intrusiveness, symptoms, disability and depression in patients with myalgic encephalomyelitis (ME). Participants were 16 patients with ME and eight patients with ME plus co-morbid disorders. The patients with co-morbid disorders reported greater illness intrusiveness than the patients with ME alone, but there were no differences between the groups on the other variables. Significant correlations were found between illness intrusiveness on the one hand, and fatigue, cognitive dysfunction, disability and depression, on the other. We conclude that ME is a disabling illness, which has a major impact on various life domains.

Fatigue in the workforce of National Health Service Trusts: levels of symptomatology and links with minor psychiatric disorder, demographic, occupational and work role factors

The aims of this study were: (1) to obtain a systematic estimate of the levels of fatigue in representative samples of the major occupational groups of health care workers; (2) to examine the relationship between fatigue and mental health as a function of occupational and work role factors; and (3) to test the proposition that fatigue arises from a combination of poor mental health and high job stress. Questionnaire data from 7720 NHS Trust staff was used. Higher levels of fatigue were reported among health care workers in comparison with general population figures. Highest levels of general fatigue, the subjective sensation of tiredness, were experienced by doctors (especially women doctors), professions allied to medicine and managers. Highest levels of fatigability, the onset of symptoms after exertion, were experienced by ancillary and nursing staff. Both general fatigue and fatigability were associated with high levels of psychological distress. Support was also found for the proposition that fatigue arises from a combination of poor mental health and high work demands.
