The Effect of Notebook

Read More About Health Care

Ten years ago, researchers stumbled onto a striking finding: Women who believed that they were prone to heart disease were nearly four times as likely to die as women with similar risk factors who didn't hold such fatalistic views. The higher risk of death, in other words, had nothing to do with the usual heart disease culprits — age, blood pressure, cholesterol, weight. Instead, it tracked closely with belief. Think sick, be sick.That study is a classic in the annals of research on the "nocebo" phenomenon, the evil twin of the placebo Tag Heuer Replica Watches effect. While the placebo effect refers to health benefits produced by a treatment that should have no effect, patients experiencing the nocebo effect experience the opposite. They presume the worst, health-wise, and that's just what they get. "They're convinced that something is going to go wrong, and it's a self-fulfilling prophecy, " said Arthur Barsky, a psychiatrist at Boston's Brigham and Women's Hospital who published an article earlier this year in the Journal of the American Medical Association. "From a clinical point of view, this is by no means peripheral or irrelevant. " But convincing doctors that their patients' problems may be more than biochemical is no simple trick. The nocebo effect is difficult to study, and medical training leads doctors to seek a bodily cause for physical ills.

The word "nocebo", Latin for "I will harm", doesn't represent a new idea — just one that hasn't caught on widely among clinicians and scientists. More than four decades after re-searchers coined the term, only a few medical journal articles mention it. Outside the medical community, being "scared to death" or "worried sick" are expressions that have long been part of the popular lexicon.

Fifteen years ago, researchers at three medical centers undertook a study of aspirin and another blood thinner in heart patients and came up with an unexpected result that said little about the heart and much about the brain. At two locations, patients were warned of possible gastrointestinal problems, one of the most common side effects of repeated use of aspirin. At the other location, patients received no such caution. When researchers reviewed the data, they found a striking result: Those warned about the gastrointestinal problems were almost three times as likely to have the side effect. Though the evidence of actual stomach damage such as ulcers was the same for all three groups, those with Hublot Replica Watches the most information about the prospect of minor problems were the most likely to experience the pain.

Barsky has even sketched out a profile of the kind of patient likely to experience the notebook effect — worse side effects and poorer outcomes — on a given drug. When Barsky sees a patient with a history of vague, difficult-to-diagnose complaints who is sure that whatever therapy is prescribed will do little to battle the problem, he says, those low expectations are inevitably met. The treatments usually fail. "Whether you trust your doctor or not probably makes a huge difference in -whether you report side effects, but there's almost no data on that," Barky said. He hopes to include information about a person's psychology in an up¬ coming placebo-controlled clinical trial to see if patients with a particular outlook on life fare better or worse than other subjects.
