The "Test Your Memory" test performs better than the MMSE in a population without known cognitive dysfunction.

Area of Science:

• Neuroscience
• Cognitive Assessment
• Gerontology

Background:

• Cognitive decline is a growing concern in aging populations.
• Accurate and accessible screening tools are crucial for early detection.
• The Mini-Mental State Examination (MMSE) is widely used but may have limitations.

Purpose of the Study:

• To compare the performance of the self-administered Test Your Memory (TYM) test with the MMSE.
• To evaluate their correlation with a comprehensive neuropsychological assessment.
• To assess their ability to differentiate cognitive function in a general population sample.

Main Methods:

• 86 participants (56-77 years) without known cognitive dysfunction underwent a neuropsychological assessment.
• Participants completed the MMSE and the TYM.
• Correlation analyses, ROC curves, and Bland-Altman plots were used for comparison.

Main Results:

• The TYM demonstrated a significantly stronger correlation with the comprehensive assessment (r=0.78) than the MMSE (r=0.55).
• The TYM showed superior discrimination between normal and modestly impaired cognition (AUC=0.88) compared to the MMSE (AUC=0.71).
• Bland-Altman analysis indicated better agreement between the TYM and neuropsychological assessment.

Conclusions:

• The TYM is a reliable tool for assessing cognitive function.
• It outperforms the MMSE in correlating with detailed neuropsychological evaluations.
• The TYM is effective in identifying subtle cognitive decrements.
