Objective: To determine the prevalence and spectrum of use of alternative t
herapy (AT) by patients with PD and to determine whether use of AT correlat
es with demographic, social, or disease-specific characteristics. Methods:
The authors administered a structured questionnaire, by interview, regardin
g the use of AT to 201 patients with PD. Demographic, social, and disease-s
pecific characteristics were recorded for all patients. Results: Eighty-one
patients (40%) used at least one AT. Vitamins and herbs, massage, and acup
uncture were most common. Users of AT were younger (p = 0.0021) and had a y
ounger age at onset of PD (p = 0.0011) than nonusers of AT. There was no co
rrelation with sex or race. Patients who used AT had a higher income (p = 0
.038) and education level (p = 0.006) than did nonusers of AT. There was no
association between the use of AT and the Hoehn and Yahr score, duration o
f PD, duration of treatment with levodopa, surgery for PD, and presence of
fluctuations. Conclusions: The use of AT is common in patients with PD. The
age at onset of PD is the most potent predictor of AT use. There is no ass
ociation between the use of AT and the severity of PD. The widespread and l
argely unexamined use of AT for PD requires more attention. This should be
directed at testing their safety and efficacy and improving physician and p
atient knowledge about the potential benefits, costs, limitations, and risk
s of AT.
