Background

Neuropsychological assessment is essential for identifying and characterizing Alzheimer’s

disease (AD), mild cognitive impairment (MCI), and related dementias. However, most

commonly used cognitive instruments are normed on Western, English-speaking, and highly

educated populations, limiting validity across multicultural, multilingual, and socioeconomically

diverse groups. These structural limitations contribute to systematic misclassification of

cognitive impairment, particularly among Black, Latino, Caribbean, and immigrant populations,

resulting in delayed diagnosis, inappropriate labeling, inequitable access to care, and

underrepresentation in research. As global dementia prevalence increases, addressing cultural

and linguistic inequities in neuropsychological assessment has become an urgent clinical and

scientific priority.

Objective

To examine key multicultural challenges affecting the accuracy of neuropsychological

assessment in dementia and to evaluate emerging innovations designed to improve cross-cultural

validity and diagnostic equity.

Methods

A structured integrative review of 112 peer-reviewed studies published between 2010 and 2025

was conducted using PubMed, PsycINFO, Scopus, CINAHL, and Google Scholar. Included

studies focused on multicultural or cross-linguistic neuropsychological assessment in AD, MCI,

or related dementias. Findings were synthesized across domains of language and educational

bias, cultural conceptualizations of cognition and aging, and assessment innovations, including

culturally adapted instruments, digital platforms, and artificial intelligence (AI)–supported

analytic approaches.

Results

Widely used cognitive screening tools, including the MMSE and MoCA, demonstrated persistent

education- and language-related bias, particularly among individuals with limited formal

education or non-English primary languages. Adjusted norms improved specificity modestly but

remained insufficient without culturally tailored test content. In contrast, culturally adapted

batteries and AI-assisted approaches integrating speech-based, performance-based, and digital

biomarkers demonstrated improved diagnostic accuracy, interpretive confidence, and clinical

relevance across diverse populations.Conclusions

Redefining neuropsychological assessment frameworks within multicultural and multilingual

contexts is essential for achieving equitable diagnosis of AD and related dementias. Culturally

responsive and technology-enhanced approaches are critical to ensuring that advances in early

detection translate equitably across diverse populations.
