Leonard A. Jason, PhD, is a professor of psychology at DePaul University in Chicago, Illinois, US and Director of the Center for Community Research at DePaul University[1] which includes the DePaul University Chronic Fatigue Syndrome Project. His ME/CFS research is mostly focused on the epidemiology and prevalence of the illness and on the impact of using various case definitions for diagnosis and research.[2]

Dr. Jason developed chronic fatigue syndrome after contracting infectious mononucleosis in 1989, necessitating a leave of absence from his university job for a year and a half. After recovering enough to return to work, he began studying chronic fatigue syndrome: “What I found was that the illness had a lousy name, chronic fatigue syndrome,” he recalled. “It had an even worse case definition. The tests used to assess people’s psychological conditions were inappropriate. The treatments being used were inappropriate. And the prevalence data was not very good. So I said to myself, ‘Boy, I’m gonna have business for the next 20 years.’”[3] He has become one of the most respected and prolific researchers of chronic fatigue syndrome.

In 2008, David Tuller profiled for The New York Times Dr. Jason's experience as both living with and researching myalgic encephalomyelitis/chronic fatigue syndrome (ME/CFS).[4]

Myalgic encephalomyelitis or chronic fatigue syndrome, often used when both illnesses are considered the same.

Myalgic encephalomyelitis or M.E. has different diagnostic criteria to chronic fatigue syndrome; neurological symptoms are required but fatigue is an optional symptom.<ref name="ICP2011primer">{{Citation
