Can brain exercises mitigate cognitive decline? A quasi-experimental evaluation of the StrongerMemory program
Bibliographic record
Abstract
The StrongerMemory program, a structured intervention involving reading aloud, writing by hand, and completing simple math problems, is designed to stimulate the prefrontal cortex and enhance cognitive functioning. This study addresses a research gap by evaluating a multi-modal cognitive intervention compared to traditional single-domain approaches. It aligns with emerging frameworks emphasizing population-informed, personalized cognitive training. A 12-week quasi-experimental study was conducted with 102 older adults (aged 59+) from three continuing care retirement communities (CCRCs) and 25 aging-in-place villages. Pre- and post-intervention cognitive outcomes were assessed using the 5-minute protocol of the Montreal Cognitive Assessment 2.1 (Mini MoCA) and the Memory Functioning Questionnaire (MFQ). ANCOVA controlled for baseline Mini MoCA differences. Weekly check-ins were used to monitor adherence. Mini MoCA scores improved from pretest (12.73 ± 2.1) to posttest (13.26 ± 2.3, p <.0001) with statistically significant recall improvement (3.44 to 3.92, p < .001). One MFQ item measuring perceived memory decline in the last year improved from pre to post (3.72 to 4.03, p < .001). ANCOVA indicated significantly lower post-intervention Mini MoCA scores among CCRC residents compared to those living in the community. Participation in StrongerMemory was associated with both objective and subjective improvement in cognitive functioning, especially for those living in the community. This low-cost, non-pharmacological program offers promise as a scalable intervention for cognitive aging. Differences across living environments suggest that social or contextual influences warrant further investigation.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one source (direct Gemma or distilled Codex), not a consensus.
