KEY: QPAR = Quick Physical Activity Rating; mPPT = Mini Physical Performance Test; CDR = Clinical Dementia Rating; MCI = Mild Cognitive Impairment; AD = Alzheimer’s Disease; DLB = Dementia with Lewy Bodies; VaD = Vascular Dementia; FTD = Frontotemporal Degeneration.
aPost-hoc analyses: Individuals 80 year and older are different from other age strata.
bPost-hoc analyses: CDR 0 different from all other CDR stages; CDR 0.5 not different from CDR 1; CDR 1, 2 and 3 are not different from each other.
cPost-hoc analyses: Controls different from MCI and all dementia etiologies; MCI different from all dementia etiologies; Dementia etiologies not different from each other.
