Assessment of Mild Cognitive Impairment Using CogEvo: A Computerized Cognitive Function Assessment Tool

Area of Science:

• Gerontology
• Neuroscience
• Primary Care Medicine

Background:

• Mild cognitive impairment (MCI) is a growing concern in aging populations.
• Early detection of MCI is crucial for timely intervention and management.
• Current screening tools like the Mini-Mental State Examination (MMSE) have limitations, including ceiling effects and educational bias.

Purpose of the Study:

• To evaluate the utility of CogEvo, a computerized cognitive function assessment tool, as a primary care screening tool for MCI.
• To explore the relationship between CogEvo performance, age, and cognitive dysfunction severity as measured by the MMSE.
• To assess CogEvo's predictive accuracy for cognitive dysfunction.

Main Methods:

• An observational, cross-sectional study involving 209 individuals (mean age 79.4 years).
• Correlation analysis between CogEvo and MMSE scores.
• Comparison of CogEvo performance across three MMSE-defined cognitive function groups (MMSE ≥ 28, MMSE 24-27, MMSE ≤ 23).
• Receiver Operating Characteristic (ROC) analysis to determine predictive accuracy.

Main Results:

• Both CogEvo and MMSE scores significantly decreased with age.
• A significant positive correlation was found between CogEvo and MMSE scores.
• CogEvo demonstrated significant differences across cognitive groups, including orientation and spatial function, without educational bias.
• ROC analysis showed moderate discrimination between cognitive groups.

Conclusions:

• CogEvo is a valuable screening tool for MCI in primary care.
• Unlike the MMSE, CogEvo avoids ceiling effects and educational bias.
• CogEvo effectively identifies age-related cognitive decline and impairment.
