The Geras Solutions Cognitive Test for Assessing Cognitive Impairment: Normative Data from a Population-Based Cohort

Area of Science:

• Neuroscience
• Gerontology
• Cognitive Psychology

Background:

• Early detection of neurocognitive disorders requires accurate and accessible screening tools.
• The Geras Solutions cognitive test (GSCT) shows promise as a digital screening instrument for cognitive impairment.
• Normative data are needed to validate the GSCT's effectiveness.

Purpose of the Study:

• To establish normative data for the GSCT in cognitively healthy individuals.
• To investigate the influence of gender and education on GSCT scores.
• To assess the test-retest reliability of the GSCT.

Main Methods:

• 144 cognitively healthy subjects (age 70, MMSE>26) from the Healthy Aging Initiative Study participated.
• All subjects completed the GSCT.
• A subset of 32 subjects completed the GSCT twice to determine test-retest reliability.

Main Results:

• The mean GSCT score was 46.0 (±4.5).
• Higher education levels (>12 years) correlated with higher GSCT scores (p=0.02).
• Gender did not significantly affect GSCT outcomes (p=0.5), and test-retest reliability was high (r(30)=0.8, p<0.01).

Conclusions:

• The study provides normative GSCT scores for healthy older adults.
• Education level is a significant predictor of GSCT performance.
• The GSCT demonstrates good test-retest reliability, supporting its validity as a cognitive screening tool.
