Chronic Fatigue Syndrome (ME/CFS)

The Chronic Fatigue Syndrome (ME/CFS) topic includes research on myalgic encephalomyelitis/chronic fatigue syndrome (ME/CFS). This serious, long-term illness can affect many body systems. It causes profound fatigue that does not improve with rest, along with other symptoms that interfere with daily life.

Physical or mental activity can make symptoms worse, sometimes greatly limiting a person’s ability to work, go to school, or take care of themselves. The causes of ME/CFS remain unclear, and there is no single diagnostic test. Research can improve understanding of the illness and help develop better approaches to diagnosis and care.
