Objective: We tested the association of individual cognitive domains measured with the Mini-Mental State Examination (MMSE) and disability. Method: Cross-sectional study in a population-based cohort aged ≥55 years (n = 4,803). Sample was divided into two groups: individuals with cognition within the normal range (CNR) (n = 4,057) and those with cognitive impairment (CI) (n = 746). Main outcome measures: The MMSE, the Katz Index (Basic Activities of Daily Living, bADL), the Lawton and Brody Scale (Instrumental Activities of Daily Living, iADL), and the Geriatric Mental State (GMS-AGECAT). Results: MMSE-orientation was associated with disability in bADL, iADL and a decrease in social participation, regardless of cognitive status. MMSE-attention was associated with disability in iADL, but only in CNR. MMSE-language was associated with disability in bADL, iADL and with reduced social participation, but only in CI. Conclusions: The associations observed between disability and orientation may have clinical and public health implications.
