Overview

• The exact cause of chronic fatigue syndrome (CFS) is unknown.

• Some theories suggest CFS may be due to:

• Epstein-Barr virus or human herpes virus-6 (HHV-6); however, no specific virus has been identified as the cause
• Inflammation in the nervous system, because of a faulty immune system response

• The following may also play a role in the development of CFS:

• Age
• Previous illnesses
• Stress
• Genetics
• Environmental factors

• CFS most commonly occurs in women ages 30 to 50.
