<div>The VCAT demonstrated moderate diagnostic accuracy in identifying Asian individuals with MCI or mild dementia. The meta-analysis found a pooled sensitivity of 80% and specificity of 75%. Patients with MCI or mild dementia showed significantly lower (<em>p</em><0.00001) VCAT scores with a mean difference of -6.85 points. The authors note that the VCAT demonstrates promise as a language-neutral and culturally unbiased tool.</div>

<div>Limitations of this review include the limited number of available studies, a lack of non-Asian populations, variability of MCI/mild dementia criteria, inconsistent reporting of demographic variables, lack of research on repeated administration of the VCAT, and significant heterogeneity across the included studies.</div>
