"Anybody who has a chronic illness has alterations in biological and psychological mechanisms," says James F. Jones, M.D., a chronic fatigue expert with the U.S. Centers for Disease Control and Prevention. "You really can't separate the brain and the body, because psychology is biology—everything that takes place in the brain is chemical or electrical. You can't have the one without the other."
"Doctors suspect that by continuing to focus on an elusive biological cause, they could be missing out on the other half of the picture—and the chance to find a solution. They have begun to re-examine the role of severe stress, depression and even personality traits in initiating and fostering disease." - Is It All in My Head? by Melissa Schorr, published on May 01, 2005 - last reviewed on July 20, 2009, Psychology Today
