Table 2.

showed the frequency distribution of medication in PD-10 patients. Although 100% patients were taking levodopa, only 9.09% (11/121) of those were taking levodopa alone and the majority of those were also taking dopamine agonists or any other PD medication. Among PD-10 patients, 43.80% (53/121) of patients were taking three PD medication, 83.02% (44/53) of whom were taking the combination of dopamine agonists, levodopa and other anti-parkinson drugs. Although higher percentage of PD-10 patients with H-Y ≥3.0 was taking COMT inhibitor (39.62% vs. 19.12%), the percentages of taking amantadine (28.30% vs. 48.53%) for patients with H-Y ≥3.0 were significantly lower. We did not observe statistically significant differences in the proportions of levodopa, dopamine agonist, MAO-B inhibitor, anticholinergics and types of PD medication used between PD-10 patients with and without H-Y ≥3.0.
