What role does language proficiency play in MoCA assessments for bilingual individuals?

Language proficiency plays a crucial role in MoCA assessments for bilingual individuals because it can significantly influence test performance and scores. The MoCA (Montreal Cognitive Assessment) is designed to evaluate various cognitive domains, including attention, memory, language, and executive functions. If a bilingual individual is not as proficient in the language used for the assessment, their performance may not accurately reflect their cognitive abilities.

For instance, if a person has a stronger command of one language but the assessment is conducted in another, their lower scores could mistakenly suggest cognitive impairment. This complication highlights the importance of considering the individual's language skills to ensure that the assessment is fair and that the results are valid. Thus, being aware of a bilingual individual's proficiency in the test language allows healthcare professionals to interpret the results more accurately and account for any discrepancies caused by language barriers.
