Researchers reviewed multiple randomized trials that tested a combination of physical exercise and transcranial direct current stimulation (tDCS) in older adults with cognitive impairment. The studies looked at how this combined approach affected overall thinking skills, memory, and executive function.
The pooled data showed a significant improvement in global cognitive function, with a moderate effect size. The analysis did not report specific numbers of participants or details on safety, tolerability, or side effects.
This finding is based on a meta-analysis, which combines results from several studies. It shows an association, not direct causation. The analysis did not report the certainty of the evidence or practice relevance.
For readers, this suggests the combined approach may be a promising area for further research. However, the evidence is not yet strong enough to change medical practice, and more studies are needed to confirm the benefits and safety.
