Brain zaps may unlock fluency for people who stutter
NCT ID NCT06740968
First seen Jun 26, 2026 · Last updated Jun 26, 2026
Summary
This study tests whether a gentle, noninvasive electrical current applied to the scalp can improve speech fluency in adults who stutter. Researchers will give 80 participants three sessions of brain stimulation while they read aloud, then measure changes in brain activity and stuttering severity. The goal is to see if this approach could become a new treatment option.
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 noninvasive, drug-free treatment to reduce stuttering in adults.
What could go wrong
This is an early-stage study with only 80 people, testing short-term effects. The stimulation may not produce lasting fluency improvements, and results may not apply to everyone who stutters.
