Placebo Effect Helps Some Psoriasis Patients

Now, a new study says placebos can help psoriasis patients get by on smaller doses of a steroid drug that dampens their immune systems.

The study authors, from the University of Rochester Medical Center in New York, think they may be able to develop other treatments that rely on the placebo effect to boost the power of lower doses of existing drugs.

"Our study provides evidence that the placebo effect can make possible the treatment of psoriasis with an amount of drug that should be too small to work," lead investigator Dr. Robert Ader, a professor at the University of Rochester School of Medicine & Dentistry, said in a news release from the school. "While these results are preliminary, we believe the medical establishment needs to recognize the mind's reaction to medication as a powerful part of many drug effects, and start taking advantage of it."
