Propsner, N M·New Jersey medicine : the journal of the Medical Society of New Jersey·1999
This article describes chronic fatigue syndrome (ME/CFS), a condition where people experience extreme tiredness that doesn't improve with rest. The fatigue often begins after a viral infection and is more commonly seen in middle-aged women. While current treatments can help manage symptoms, researchers are working to better understand the condition and develop more effective approaches.
