Science States Placebo Effect Is Real
Monday, September 22nd, 2003Despite a recent report questioning whether an inactive medical treatment
can cause improvement in patients’ symptoms, new research from Canada
suggests that the "placebo effect" is real.
The study found that Parkinson’s disease patients who took an inactive
placebo pill experienced a substantial increase in the release of a brain
chemical called dopamine. The release of dopamine is impaired in people
with Parkinson’s.
The researchers measured dopamine levels under two different conditions.
During one part of the study, patients did not know whether they were
taking the Parkinson’s drug apomorphine or a placebo. Dopamine was also
measured under normal conditions when patients knew they were not taking a
placebo.
