The placebo effect has long been an interesting phenomenon. Reportedly, about one-third of patients who have received a placebo rather than medication with active ingredients responded because they believed they were given the "true" medication or because they expected to experience relief from symptoms. Positive thinking, faith, mind over matter - all elicit good results.
Research is now showing that the placebo effect is likely more than just the result of wishful thinking. PET scans, MRIs, and EEGs (diagnostic tests which show brain activity) of patients receiving placebo have revealed actual changes in brain chemistry. Essentially, the processes of the brain are affected by the placebo, according to researchers. MSNBC reports that researchers are trying to better understand the processes so the placebo effect can be utilized for controlling chronic pain and other aspects of illness.
