This study aims to evaluate the effectiveness of several neuropsychological tests in detecting Mild Cognitive Impairment (MCI) and Alzheimer’s Disease (AD) among Lebanese Arabic-speaking individuals.

A battery of cognitive assessments was administered, including the Mini-Mental State Examination (MMSE), Modified Mini-Mental State (3MS), Montreal Cognitive Assessment (MoCA), Brief Visuospatial Memory Test-Revised (BVMT-R), Digit Span, and Verbal Fluency tests. Participants were divided into control, MCI, and AD groups. Sensitivity, specificity, and diagnostic accuracy were evaluated for each test.

Our findings suggest that the 3MS, in combination with other cognitive tests, is a reliable tool for screening MCI and AD in Lebanon. While these results are consistent with international standards, further validation with a broader population is necessary to improve generalizability. This study advances the development of culturally adapted cognitive assessments, emphasizing the need to consider cultural factors in neuropsychological evaluations.
