The accuracy of the MoCA test has been a topic of interest for researchers and clinicians alike. As a cognitive assessment tool, it has been found to be superior to the MMSE test in detecting mild cognitive impairment (MCI) and early stages of dementia.

The MoCA test's enhanced sensitivity and specificity are attributed to its more comprehensive nature. It assesses various cognitive domains, including memory, language, executive function, attention, visuospatial abilities, and abstraction. This allows for a more nuanced evaluation of cognitive function.

In contrast, the MMSE test, while widely used, is known to have limitations in detecting early cognitive decline. It is often criticized for being too brief and failing to capture the full spectrum of cognitive abilities.

When comparing the two tests, the MoCA test consistently demonstrates a higher ability to accurately identify individuals with MCI and early dementia, while also reducing the number of false positives (incorrectly identifying healthy individuals as having a disease).
