Can a brain zap and computer game sharpen aging minds?

First seen Jun 25, 2026 · Last updated Jun 26, 2026 · Updated 2 times
Summary
This study tested whether combining a computer-based speed-of-processing training with a gentle electrical brain stimulation (alpha-tACS) could improve how quickly people with mild cognitive impairment process visual information. The trial planned to enroll 40 adults aged 65 and older, comparing the active stimulation plus training to a sham (placebo) stimulation plus training. The study was terminated early, so results are limited, but the goal was to see if this combination could boost thinking speed and potentially help with memory and other mental skills.
What this could mean
Our plain-language read of the trial. This is informational only — not medical advice or a prediction.
Active substance
alpha-tACS (a mild electrical brain stimulation device) and speed-of-processing training (a computer-based mental exercise)
What this could lead to
If it works, this could point toward a non-drug way to slow or improve thinking speed and memory in people with mild cognitive impairment.
What could go wrong
This was a small, early-stage trial that was terminated, so results are limited. The approach may not produce lasting or meaningful benefits, and brain stimulation can cause mild side effects like tingling or headache.
