ME/CFS Can Affect Anyone

Millions of people worldwide are affected by Myalgic Encephalomyelitis/Chronic Fatigue Syndrome (ME/CFS). Yet the causes, diagnostic markers, progression, and FDA-approved treatments remain unknown. The shared vision of the ME/CFS Collaborative Research Network (ME/CFSnet) is to encourage collaborative research in partnership with individuals and advocacy groups to understand the disease and develop better diagnosis and treatment.
