What symptoms are used to diagnose CFS?
—————————— Subject: 2.021 CFS definition In addition to the official researchers’ definition discussed below, patients and experienced clinicians have noticed symptom patterns that seem prominent in CFS. These are described in question 1.01 above, and also include the observations that cognitive dysfunction often increases over time (over several years), and that brain scans often show that blood flow to the brain is decreased. CFS is defined somewhat differently by various medical groups in different countries. The 1994 research definition published by the U.S. Centers for Disease Control and Prevention recommends a step-wise approach for identifying CFS cases. The first step is to clinically evaluate the presence of chronic fatigue, i.e. “self-reported persistent or relapsing fatigue lasting 6 or more consecutive months”. Conditions that explain chronic fatigue should exclude a diagnosis of CFS. These are: – “any active medical condition that may explain the prese
