A study published in the September 11 issue of Neurology found that among 201 patients with Parkinson disease, 40% used at least one type of alternative therapy and more than half failed to inform their physicians about such use.
The researchers, at Johns Hopkins Medical Institutions, said the high percentage of patients who did not tell their physicians about alternative therapy use is "concerning," since recent studies have shown that alternative therapies may have potentially harmful effects and interactions with other drugs.
