Patients’ expectations play an important role in the effectiveness of their treatments, and the placebo effect has been well documented, especially in people with Parkinson’s disease. We wanted to see if the people’s perceptions of the cost of the drug they received would affect the placebo response.
Placebo can be the physician's friend when it enhances therapeutic efficacy. The effects of placebo also can confound clinical trial outcomes or lead to endorsement of worthless treatments. For patients with Parkinson's disease, placebo effect is often robust and enduring. The outcome of this study, despite its limitations, opens our eyes to another nuance of placebo effect with implications for clinical practice, the research enterprise, and health policy.
