"Lyme
disease patients can mimic another chronic disease such as
Fibromyalgia, Chronic Fatigue, and a mood disturbance," says Daniel
Cameron, MD, MPH, and internist and epidemiologist who specializes in treating Lyme.
"New onset of psychiatric symptoms in a previously well person is a
really good reason to start looking for tick-borne disease." Reihman
believes these symptoms may stem from an autoimmune response in which
antibodies created to fight Lyme and co-infections go after healthy
brain tissue.
