This 12-week, open-label cluster-randomized controlled trial evaluated a MIND-based diet, with or without digital cognitive training, in 80 adults aged 65 years or older with mild cognitive impairment attending daycare centers. Compared with control, both intervention groups improved in cognitive function, nutritional status, quality of life, and activities of daily living; each reported comparison had P < 0.001. Maximum muscle strength also improved versus control in the combined diet-and-training group, but not in the diet-only group. The abstract does not provide effect sizes, so the magnitude of these changes cannot be assessed.
Key findings
- Both diet groups improved K-MMSE2 cognitive function versus control (P < 0.001).
- Both diet groups improved nutritional status, quality of life, and ADL measures versus control (all P < 0.001).
- Maximum muscle strength improved versus control only in the diet-plus-digital-training group (P < 0.001).
Why it matters
The findings suggest that a structured dietary intervention may support several functional and patient-reported outcomes in older adults with MCI. The additional muscle-strength result in the combined group raises the possibility that digital cognitive training may complement dietary support, although the abstract does not establish the size or durability of benefit.
What to keep in mind
The trial was open-label, lasted 12 weeks, and included 80 participants. The abstract reports significance tests but not effect sizes, limiting assessment of the magnitude of benefit.
