Zapping the brain to sharpen focus after concussion: new study
NCT ID NCT04925453
First seen Jun 26, 2026 · Last updated Jun 27, 2026 · Updated 1 time
Summary
This completed pilot study tested whether a gentle brain stimulation technique called tDCS, combined with computer-based cognitive training, can improve attention and working memory in 56 active-duty service members who had a mild traumatic brain injury at least 6 months earlier. Participants received either real tDCS or a sham (fake) stimulation while doing attention and memory exercises over several sessions. Researchers measured changes in brain activity, cognitive tests, and symptom reports to see if the combination helps.
What this could mean
Our plain-language read of the trial. This is informational only — not medical advice or a prediction.
- Active substance
- transcranial direct current stimulation (tDCS) combined with cognitive training
- What this could lead to
- If it works, this could point toward a noninvasive, drug-free way to ease attention and memory problems after mild traumatic brain injury.
- What could go wrong
- This is a small pilot study (56 people) with no phase, so results are preliminary. The sham group also got cognitive training, so any added benefit of tDCS may be small or unclear.
