Trajectories of MMSE and MoCA scores across the healthy adult lifespan in the Italian population

BACKGROUND: This study compares the performance at the Mini-Mental State Examination (MMSE) and Montreal Cognitive Assessment (MoCA) across the healthy adult lifespan in an Italian population sample. METHODS: The MMSE and MoCA were administered to 407 Italian healthy native-speakers (165 males; age range 20–93 years; education range 4–25 years). A generalized Negative Binomial mixed model was run to profile MMSE and MoCA scores across 8 different age classes (≤ 30; 31–40; 41–50; 51–60; 61–70; 71–80; 81–85; ≥ 86) net of education and sex. RESULTS: MMSE and MoCA total scores declined with age (p < 0.001), with the MoCA proving to be “more difficult” than the MMSE (p < 0.001). The Age*Test interaction (p < 0.001) indicates that the MoCA proved to profile a sufficiently linear involutional trend in cognition with advancing age and to be able to detect poorer cognitive performances in individuals aged ≥ 71 years. By contrast, MMSE scores failed in capturing the expected age-related trajectory, reaching a plateau in the aforementioned age classes. DISCUSSION: The MoCA seems to be more sensitive than the MMSE in detecting age-related physiological decline of cognitive functioning across the healthy adult lifespan. The MoCA might be therefore more useful than the MMSE as a test for general cognitive screening aims.
