Abstract:
The chronic fatigue syndrome has recently been more frequently diagnosed. Yet it is unknown if this syndrome represents a disease entity of its own or merely a diagnostic label for a miscellaneous group of disorders. Further investigations are needed to find out if the syndrome has an organic or psychosomatic aetiology, or a mixture of both. In the meantime it is the responsibility of the clinician to make this decision in each individual case.
