A new analysis of 15 studies involving nearly 2,000 older adults suggests that digital technology interventions, such as computer-based brain training or online therapy, may help improve cognitive function and reduce symptoms of depression and anxiety. The review found significant improvements in thinking skills, with a large effect size, and moderate reductions in depression and anxiety. However, the evidence is considered low certainty, meaning more high-quality research is needed to confirm these benefits.
The analysis did not find a significant effect on loneliness, though there was a trend toward improvement. The studies varied widely in the types of digital tools used, how long they were used, and the populations studied. No safety concerns were reported, but the review did not track side effects or dropouts.
Because the evidence is limited, these findings should be seen as promising but not definitive. Older adults interested in using digital tools for brain health should discuss options with their healthcare provider. The results suggest that digital interventions could be a helpful addition to other healthy habits, but they are not a replacement for medical care.
