Non-demented hospital controls: subjective memory complaints and psychiatric disorders; Other dementias: mild cognitive impairment, dementia with Lewy bodies, frontotemporal lobar dementia, vascular dementia, progressive supranuclear palsy, corticobasal degeneration, normal pressure hydrocephalus, and Creutzfeldt-Jakob disease. ^aKruskall Wallis test was used for comparing means across continuous nonstandard distributed variables. ^bChi-square test was used for comparing means across dichotomized variables.
