Area of Science:

Neuropsychology
Gerontology
Digital Health

Background:

The National Alzheimer's Coordinating Center's Uniform Dataset (UDS) provides executive function measures.
Tablet-based Cognitive Assessment Tool (TabCAT) Match is a digital neuropsychological test.

Purpose of the Study:

Compare TabCAT Match to UDS executive function measures.
Evaluate the diagnostic utility of TabCAT Match across Clinical Dementia Rating (CDR) stages.

Main Methods:

Analyzed data from 1792 diverse older adults.
Used receiver operating characteristic curves and analyses of covariance.
Conducted sensitivity analyses across education and language groups.

Main Results:

All measures differentiated CDR stages.
TabCAT Match showed highest classification accuracy (AUC=0.862) for distinguishing cognitively unimpaired from impaired individuals.
TabCAT Match demonstrated advantages in non-English tested groups compared to UDS tests.

Conclusions:

Efficient neuropsychological measures are crucial for diagnosis and monitoring.
TabCAT Match is sensitive to impairment and suitable for diverse demographics.
Digital tools like TabCAT Match can optimize cognitive assessment.
