Myalgic encephalomyelitis/chronic fatigue syndrome (ME/CFS) is comparable to multiple sclerosis, diabetes or rheumatoid arthritis in prevalence (∼0.2% to 1%), long-term disability, and quality of life,[1–5] yet the scale of biomedical research and funding has been pitifully limited, as the recent National Institutes of Health (NIH) and Institute of Medicine reports highlight.[6,7] Recently in the USA, NIH Director Francis Collins has stated that the NIH will be ramping up its efforts and levels of funding for ME/CFS,[8] which we hope will greatly increase the interest in, and resources for researching this illness. Despite scant funding to date, researchers in the field have generated promising leads that throw light on this previously baffling illness. We suggest the key elements of a concerted research programme and call on the wider biomedical research community to actively target this condition.

Myalgic encephalomyelitis/chronic fatigue syndrome (ME/CFS) is as prevalent and disabling as multiple sclerosis, diabetes and rheumatoid arthritis but biomedical research into the condition has been grossly underfunded. However, the NIH is committed to ramping up funding for this illness and there are now promising research leads. We indicate clues to the biological mechanisms that may perpetuate the condition and suggest the key elements of a concerted research programme. In the absence of effective treatments, study of mechanism remains a key priority including the possible role of stochastic factors.
We identify the three most interesting major categories of causal model: (1) the brain is responding normally and symptoms are due to persistent signal input from peripheral tissues, such as cytokines or metabolites; (2) there is a persistent abnormality of ‘housekeeping’ processes in the brain, such as an increase in activation of microglia; and (3) there is a persistent abnormality in neural signalling in sensory pathways.
We recommend seven important, practical steps to make progress towards effective treatments: (1) build research infrastructure, including population-based cohorts with close attention to diagnostic criteria; (2) use new, developing techniques for brain imaging; (3) pursue promising immunological leads, such as natural killer cell abnormalities, cytokine shifts, auto-antibodies, and immune responses to viruses such as Epstein-Barr virus; (4) further explore autonomic/endocrine regulation; (5) extend the research on post-exertional changes in physiology; (6) attempt to replicate key findings to determine which are robust; and (7) present data in a way that allows subgroup analysis, and always provide raw data.
We conclude that the problem of ME/CFS now looks solvable and we call on the wider biomedical research community to target the condition.
