Digital Mahjong-Based Cognitive Engagement Intervention for Older Adults: Randomized Controlled Trial.

Digital games improve cognitive function in older adults, offering an engaging way to maintain memory and mental sharpness.

BACKGROUND: Gamified digital training may support long-term engagement in aging populations, yet randomized evidence linking behavioral effects to convergent neuroimaging outcomes remains limited. Compared with controls, the intervention group showed a greater improvement in Montreal Cognitive Assessment delayed recall (between-group difference=-0.79 points, 95% CI -1.538 to -0.042; P=.04).
