Lifestyle app trial reports higher cognitive test scores in older adults with mild impairment
An app supporting diet and physical activity outperformed occasional general advice on cognitive tests, without establishing prevention of dementia.
Based on the published abstract. The full paper may contain additional methods, results and limitations.
The 30-second takeaway
At 52 weeks, the app group scored higher than the advice group on the study's main cognitive test and a naming test. This supports a benefit on the measured tests in this selected population. The abstract does not establish whether the difference was noticeable in daily life or whether dementia risk changed.
The abstract reports statistical significance but gives no group mean changes, between-group score difference or confidence interval, making the size and practical importance of improvement unclear.
What researchers found
MMSE-KC cognitive test
App intervention versus general advice at 52 weeks; the difference was statistically significant, but its size in score points was not reported.
What the app addressed
The intervention combined diet and physical activity management rather than testing either component separately. Participants already had mild cognitive impairment and an additional risk factor, which limits how broadly these findings can be applied.
What improved
The main outcome was change on a Korean cognitive screening test. A separate naming test also favored the app group. These results concern test performance; the abstract does not report dementia diagnoses as an outcome.
