Professional ethics in complementary and alternative medicines in management of Parkinson’s disease

The practice of complementary and alternative medicine (CAM) is not, at present, considered an integral part of conventional medicine. As the popularity of CAM grows and access to information about CAM increases through the media and internet where CAMs are often promoted, patients are at risk of exposure unvalidated information. Therefore, there is a need for physicians to examine objectively the efficacy and safety of CAM, compare it with current medications, and become actively involved in the CAM treatment with patients. In accordance with these needs, this manuscript reviews the utility, scientific evidence, safety and cost-effectiveness of CAM in the treatment of Parkinson's disease (PD). We also address the ethical issues of CAM practices.
