Leonard A. Jason, PhD, is a professor of psychology at DePaul University in Chicago, Illinois, USA and Director of the Center for Community Research at DePaul University which includes the Depaul University Chronic Fatigue Syndrome Project.

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.’”[1] 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).[2]

Chronic Fatigue Syndrome Advisory Committee[edit | edit source]

Dr. Jason served as a voting member of the Chronic Fatigue Syndrome Advisory Committee for the U.S. Department of Health and Human Services from April 1, 2004 to April 1, 2011.[10]

Open letter to The Lancet[edit | edit source]

Two open letters to the editor of The Lancet urged the editor to commission a fully independent review of the PACE trial, which the journal had published in 2011. The first, written in 2015, was signed by Dr. Jason and five of his colleagues. In 2016, thirty-six additional colleagues in the ME/CFS field, signed the second letter.

Pediatric case definition[edit | edit source]

ME/CFS Common Data Element (CDE) Project[edit | edit source]

Dr Jason serves on the Baseline/Covariate Working Group of the Myalgic Encephalomyelitis/Chronic Fatigue Syndrome Common Data Element (CDE) Project sponsored by the National Institute of Neurological Disorders and Stroke and the Centers for Disease Control and Prevention.[14] This working group reviewed data collection instruments widely used by investigators in the ME/CFS field, and either recommended their use unchanged or (more often) proposed some modifications.[15]

Chronic Fatigue and Immune Dysfunction Syndrome (CFIDS) - Chronic Fatigue and Immune Dysfunction Syndrome is another term for Chronic Fatigue Syndrome, but one which emphasizes the immunological aspects of the disease. Popular in the 1990s, this term has apparently fallen into disuse.

myalgic encephalomyelitis (M.E.) - A disease often marked by neurological symptoms, but fatigue is sometimes a symptom as well. Some diagnostic criteria distinguish it from chronic fatigue syndrome, while other diagnostic criteria consider it to be a synonym for chronic fatigue syndrome. A defining characteristic of ME is post-exertional malaise (PEM), or post-exertional neuroimmune exhaustion (PENE), which is a notable exacerbation of symptoms brought on by small exertions. PEM can last for days or weeks. Symptoms can include cognitive impairments, muscle pain (myalgia), trouble remaining upright (orthostatic intolerance), sleep abnormalities, and gastro-intestinal impairments, among others. An estimated 25% of those suffering from ME are housebound or bedbound. The World Health Organization (WHO) classifies ME as a neurological disease.

etiology The cause of origin, especially of a disease.
