Abstract:
Fatigue is a common complaint in general practice and is often associated with psychiatric and psychosocial problems and demoralization. Although the Centers for Disease Control definition of chronic fatigue syndrome (CFS) excludes pre-existing psychiatric illness, common psychosocial problems short of a clinical disorder (such as irritability, difficulty in thinking, inability to concentrate, depression and sleep disturbance) overlap with the criteria for CFS.
Psychological states can affect the course of CFS or become confused in the patient’s and doctor’s mind with the course of infection. The core dilemma in practice is how aggressively to pursue a possible basis for CFS when it persists in the absence of an identifiable external cause. Possibilities for exploration are numerous and potentially expensive. In practice, the persistence of doctors depends on the patient’s illness behaviour, on financial and organizational factors, and on the culture of medical care and practice styles.
It is essential to differentiate the appropriate management of CFS from scientific study where intensive investigation may be warranted. In practice doctors should proceed in a manner that conveys concern, supports function, and avoids dysfunctional illness behaviour and inadvertent legitimization and reinforcement of disability.
