Myalgic encephalomyelitis/chronic fatigue syndrome

Question Question


Listen
What are the recommendations for palliative care for chronic fatigue syndrome?; What are the staging levels for this illness?

Answer Answer


Listen
Myalgic encephalomyelitis/chronic fatigue syndrome (ME/CFS) is an umbrella term that includes both myalgic encephalomyelitis (ME) and chronic fatigue syndrome (CFS). It is a serious, chronic and complex disease that affects many systems of the body and can profoundly impact daily activities. The main symptom is disabling fatigue that does not improve with rest and lasts at least 6 months.[1][2] Fatigue may get worse after activity, which is known as post-exertional malaise. Other signs and symptoms may include muscle pain, joint pain, concentration and memory problems, headaches, sleep problems, fever, sore throat, and/or tender lymph nodes.[3][1]  ME/CFS generally occurs in young adults (20 to 40 years of age) and is twice as common in women.[1][4][2][5] 

The exact cause is not known, but symptoms may be triggered by an infection.[4][1] Diagnosis can be difficult as there are no specific laboratory tests and the symptoms are common to a number of different illnesses. There is no cure or effective treatment for this condition but there are several clinical trials.[3][6][5] 

While the term ME/CFS is widely used, there is still a debate in the medical literature about the relationship between myalgic encephalomyelitis and chronic fatigue syndrome and there is no universally accepted definition.[7]  The term “systemic exertion intolerance disease” has been proposed as new term for both diseases.[6]
