Electric zaps to the brain may tame chronic migraine
NCT ID NCT07743814
First seen Aug 04, 2026 · Last updated Aug 05, 2026 · Updated 1 time
Summary
This trial tests whether a non-invasive brain stimulation technique called transcranial direct current stimulation (tDCS) can reduce the number of headache days in people with chronic migraine. Participants will receive either real or sham (inactive) stimulation over the motor cortex during three sessions, while continuing their usual preventive medications. The study tracks headache frequency over 12 weeks to see if the stimulation makes a meaningful difference.
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) — a non-invasive brain stimulation technique using a mild electrical current applied to the scalp over the primary motor cortex.
- What this could lead to
- If effective, tDCS could offer a drug-free option to reduce headache frequency in chronic migraine, potentially helping those who cannot tolerate preventive medications.
- What could go wrong
- This is a small early-stage trial with only 32 participants, and the effect may be modest or not lasting. As with any brain stimulation, there is a small risk of discomfort or side effects.
