Any comments welcome on an article I was given:
Pub: Science Magazine
Date: !0 Aug 2001 Vol 293
www.sciencemag.org
Headline:
Expectation and Dopamine Release: Mechanism of the Placebo Effect in
Parkinson's Disease
The power of placebos has long been recognized for improving numerous
medical conditions such as Parkinson's Disease (PD). Little is known,
however, about the mechanism underlying the placebo effect. Using the
ability of an endogenous dopamine to compete for Craclopride binding
as measured by positron emission tomography. we provide in vivo
evidence for substantial release of endogenous dopamine in the
striatum of PD patients in response to placebo. Our findings indicate
that the placebo effect in PD is powerful and is mediated through
activation of the damaged nigrostriatal dopamine system.
Apologies if this has been discussed before and I would appreciate
any pointers to further discussion of the aforementioned.
The magazine is a respected journal and I am sure this article must
have stirred up some controversy...
Thanks for your input,
