Values are presented as mean (standard deviation).
BDI-II = Beck Depression Inventory-II; DDE = dopaminergic dose equivalence; MMSE = Mini-Mental State Examination; PIGD = postural instability and gait dominant; TD = tremor dominant; UPDRS III = motor section of the Unified Parkinson's Disease Rating Scale. There were no significant differences in age, education, MMSE or BDI-II between the two groups, though there were differences in gender (P < 0.05).
