Use of nutritional supplements in patients with Parkinson's disease: a cause for concern?

摘要

The present study was conducted at an academic movement-disorders center in the US during 2001-2002. A total of 120 patients with idiopathic PD (mean age 68.2 +- 11.65 years, 67 men and 53 women) completed a 33-item questionnaire about their use of nutritional supplements, defined as "any supplement used in addition to their prescription medication, such as vitamins or herbal medications that could be purchased over-the-counter".
