Brain zaps may wake up coma patients – early trial launches

NCT ID NCT07213869

First seen Jun 24, 2026 · Last updated Jun 27, 2026 · Updated 2 times

Summary

This study tests whether a gentle, non-invasive brain stimulation technique called alpha tACS can improve consciousness in people who have been in a vegetative or minimally conscious state for 3–12 months after a traumatic brain injury. Five adults will each receive alternating two-week periods of stimulation and no stimulation over three months. The goal is to see if the stimulation leads to measurable improvements in awareness and brain activity.

What this could mean

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

Active substance
transcranial alternating current stimulation (tACS)
What this could lead to
If it works, this could point toward a new non-drug treatment to help people with disorders of consciousness regain awareness.
What could go wrong
This is a very early, tiny study (only 5 people) with no control group. The results may not apply to others, and the treatment may show no clear benefit.
