(HealthDay News) -- Chronic Fatigue Syndrome (CFS) is characterized by a feeling of extreme tiredness that lasts more than six months and cannot be explained by another medical condition, says the U.S. Centers for Disease Control and Prevention.
CFS does not improve with bed rest, and typically gets worse with physical activity.
Other symptoms of CFS include muscle pain or weakness, and difficulty with memory or concentration. CFS affects far more women than men, and most patients are between the ages of 40 and 50.
There are no laboratory tests or procedures that can officially diagnose the condition, the CDC says. Treatments usually focus on easing symptoms, and preventive measures to reduce stress and overexertion. Dietary changes and physical therapy also may be in order.
