In a
recent study, researchers found a patient's perception or
expectation of a drug based on how much it costs, significantly
affects the drug's efficacy. The medical team gave a group of
volunteers with Parkinson's disease two shots of a placebo drug
for the disease and participants were not told it was a simple
saline solution. Doctors told the patients they were receiving two
drugs, one shot and then the second after the first wore off.
Prior to administering the shots, doctors told the participants
each drug had proven equally effective, but one cost $100 per dose
and the other cost $1,500 per dose. Both doses were the exact same
saline solution.
Results
showed the 'expensive' placebo minimized hand shaking and improved
motor skills among the Parkinson's disease patients more
effectively than did the 'cheap' placebo. Researchers also found
the difference in efficacy was most pronounced among patients who
admitted to expecting an improved result from the expensive
version of the drug. The study was recently published in the
journal Neurology. I think I can. I think I can. . .
