Clinical Manifestations.

Area of Science:

• Neuroscience
• Gerontology
• Digital Health

Background:

• Traditional cognitive assessments can be time-consuming.
• Digital cognitive tests offer a potential alternative for efficient evaluation.
• The TabCAT Match test assesses executive function and processing speed.

Purpose of the Study:

• To evaluate the concurrent and predictive validity of the TabCAT Match test.
• To compare TabCAT Match performance against Uniform Dataset (UDS) attention and executive function tests.
• To assess the utility of TabCAT Match in differentiating cognitive decline stages.

Main Methods:

• The TabCAT Match test and UDS cognitive tests were administered to 441 older adults.
• Concurrent validity was assessed using receiver operating characteristic (ROC) analysis.
• Predictive validity was examined using longitudinal data from 100 participants over 2 years.
• Statistical analyses included ANCOVAs and linear mixed-effects models, adjusting for demographic factors.

Main Results:

• TabCAT Match scores significantly differed across Clinical Dementia Rating Scale (CDR) stages 0-2.
• TabCAT Match demonstrated comparable or superior area under the curve (AUC) values compared to UDS tests for differentiating cognitive stages.
• Longitudinal analysis showed significant decline in TabCAT Match scores for participants with mild dementia (CDR 1) over 2 years.

Conclusions:

• The TabCAT Match test is a valid and efficient digital tool for assessing cognitive function in older adults.
• It performs comparably or better than traditional UDS measures in differentiating and monitoring disease severity.
• Its 2-minute self-administered format makes it a practical alternative for clinical settings.
