What this trial studies

This study evaluates the performance of healthy participants on computerized cognitive tasks to gather normative data for early detection of cognitive decline associated with aging. Participants are divided into groups based on age and ethnicity, with assessments conducted over three years to track changes in cognitive performance. The study aims to understand health disparities in cognitive testing and improve the reliability of cognitive assessments across diverse populations.

Who should consider this trial

Good fit: Ideal candidates include healthy adults aged 60 to 89, as well as younger participants aged 18 to 89 who can use a computer mouse and touch screen.

Not a fit: Patients with a history of psychiatric disorders, strokes, substance abuse, or other medical conditions that affect cognitive testing may not benefit from this study.

Why it matters

Potential benefit: If successful, this study could lead to earlier detection of cognitive decline, allowing for timely interventions in at-risk individuals.

How similar studies have performed: Other studies have shown promise in using computerized cognitive assessments for early detection of cognitive decline, making this approach both relevant and potentially impactful.
