Core Tip

Core tip: This study was designed to address the question of how to identify early cognitive impairment and how to monitor cognitive impairment over time with high reliability. This is critical in patients at risk for age-related cognitive decline. The study results demonstrated that Cognivue - through its unique adaptive psychophysics technology - had good validity and psychometric properties, as well as superior test-retest reliability compared to the St. Louis University Mental Status examination. Therefore, as a quantitative, computerized, assessment tool, Cognivue represents a safe and effective method for clinicians to more conveniently and effectively identify and track cognitive impairment.
