Could a gentle brain zap ease PTSD symptoms? new study investigates
NCT ID NCT05895006
First seen Jun 25, 2026 · Last updated Jun 26, 2026 · Updated 1 time
Summary
This study looks at how the brains of people with PTSD process sensory information differently. Researchers will use a mild electrical current (tACS) applied to the scalp to see if it can change brain activity and reduce feelings of anxiety and hypervigilance. The study involves 160 adults aged 18-50, including those with PTSD and healthy volunteers, and uses EEG and fMRI to measure brain changes.
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 successful, this could point toward a non-invasive brain stimulation treatment for anxiety and hypervigilance in PTSD.
- What could go wrong
- This is an early-stage, basic science study focused on understanding brain mechanisms, not a treatment trial. The sample is small and results may not lead to a direct therapy.
