Summary

This study tests a gentle, non-invasive brain stimulation technique called so-tDCS in 80 older adults who have mild memory and sleep complaints. Participants will receive either real or sham stimulation over 4 weeks. Researchers will track changes in memory, sleep quality, and brain health markers to see if this approach can help.

What this could mean

Our plain-language read of the trial. This is informational only — not medical advice or a prediction.

Active substance: High-definition slow-oscillatory transcranial direct current stimulation (so-tDCS) – a gentle, non-invasive brain stimulation device
What this could lead to: If it works, this could offer a safe, non-drug way to ease memory and sleep problems in older adults, potentially slowing cognitive decline.
What could go wrong: This is an early-stage trial with only 80 participants, so results may not apply to everyone. The effect may be small or temporary, and individual responses vary.
