Brief Summary

Exploring epigenetic mechanisms of Myalgic Encephalomyelitis / Chronic Fatigue Syndrome (ME/CFS) is crucial to understand the mechanisms underlying its pathophysiology. Three potential candidates have been selected (BDNF, COMT, and HDAC genes). DNA methylation in the promoter regions of those genes will be explored. The investigators designed a randomised controlled trial and will enrol 70 patients with ME/CFS and 35 age-, sex-, and BMI-matched healthy controls. Both groups will be randomised in 2 groups and receive either one session of aerobic exercise or a validated test designed to trigger mental stress and mental fatigue. The primary aim is to assess genetic and epigenetic mechanisms of BDNF, COMT and HDAC genes in response to exercise and the stress task.
