Post hoc Bonferroni correction for three group comparisons at p < 0.0167; a = PD‐NC versus PD‐PDDI; b = PD‐MCI versus PDD.
PD‐NC = Parkinson's disease‐normal cognition; PD‐MCI = mild cognitive impairment in Parkinson's disease using the two standard deviation cut‐off; PDD = Parkinson's disease dementia; SD = standard deviation; SQLC = Scale of Quality of Life of Care‐Givers; HADS‐A = Hospital Anxiety and Depression Scale‐Anxiety subscale; HADS‐D = Hospital Anxiety and Depression Scale‐Depression subscale; NPI = Neuropsychiatric Inventory.
