Note. Values are expressed by median; UPDRS III = Unified Parkinson's Disease Rating Scale subscale III (range 0–108); MMES = Mini-Mental State Examination (range 0–30); BDI = Beck Depression Inventory (range 0–63); ROCF = Rey-Osterrieth Complex Figure Test; A = group with lower tasks performance; B = group with higher tasks performance; ∗p < .050, .p < .1.
