Jay A. Goldstein is an American physician and author. He trained in psychiatry but is board-certified in family practice. After his studies, he focused on the field of neurology and neuropharmacology, inventing what he calls neurosomatic medicine. For two decades he treated primarily patients with chronic fatigue syndrome and fibromyalgia, which he considers to be neurosomatic illnesses. Goldstein has published over 40 papers in peer-reviewed journals about many different subjects, primarily related to pharmacotherapy, often pioneering the use of a medication for an off-label use. He has authored five medical books, most of them about chronic fatigue syndrome. Since 1988 Goldstein has contributed extensively to the CFS publications The CFIDS Chronicle and The National Forum. He has also helped to organize of several conferences about the illness. He lives in Orange, California with his wife Gail and their son Jordan.
