Introduction
Overview
Overview
- The Centers for Disease Control (CDC) describes CFS as a distinct disorder with specific symptoms and physical signs, based on ruling out other possible causes. CFS is diagnosed after excluding other possible causes of fatigue.
- A diagnosis of CFS must mainly based on clinical presentation which includes the:
- absence of other causes of chronic fatigue,
- at least four CFS-specific symptoms, and
- extreme, long-term fatigue
- Therefore, there are no specific tests to confirm the diagnosis of CFS.
