Neuropsychological test scores of the pwPD group.

	pwPD	Cut-off defining
	(n = 27)	pathological condition
MoCA, mean (SD)	24.2 (2.9)	15.5 (≤)
TMT part A, median (IQR)	42 (30–56)	94 (≥)
TMT part B, median (IQR)	73 (58–139)	283 (≥)
TMT part B-A, median (IQR)	40 (18–68)	187 (≥)
Phonemic fluency, mean (SD)	35.4 (9.5)	17.35 (≤)
Semantic fluency, mean (SD)	42.9 (8.5)	25 (≤)

Reported scores have been adjusted for age and education. Mean and SD were reported in case of normal distribution, while median and IQR were reported in case of non-normal distribution. The respective pathological cut-off scores are also shown.

IQR, interquartile range; MoCA, Montreal Cognitive Assessment; n, number; pwPD, persons with Parkinson's disease; SD, standard deviation; TMT, Trail Making Test; yrs-years.

MoCA scores were adjusted according to Santangelo et al. (24), TMT according to Giovagnoli et al. (28), phonological fluency according to Carlesimo et al. (27) and semantic fluency according to Novelli (26). The respective cut-off scores for pathological condition are reported.
