Diagnostic Criteria for Chronic Fatigue Syndrome

The cause or causes of CFS have not been identified, and no specific diagnostic tests are available for the condition. In order to be diagnosed with chronic fatigue syndrome, a patient must satisfy two criteria:

1. Severe chronic fatigue that lasts for at least six months and cannot be explained by other known medical conditions whose manifestations include fatigue.

2. A patient also must have at least four of the following symptoms: 

* malaise after physical exertion 
* impaired memory or concentration 
* unrefreshing sleep 
* muscle pain 
* multi-joint pain without redness or swelling 
* tender cervical or axillary lymph nodes 
* sore throat 
* headache

The symptoms must have persisted or recurred during six or more consecutive months of illness and must not have predated the fatigue.
