Can magnetic pulses ease Post-Concussion headaches?
NCT ID NCT05857761
First seen Jun 24, 2026 · Last updated Jun 27, 2026 · Updated 1 time
Summary
This study looks at why some people get persistent headaches after a mild concussion and tests a new treatment called repetitive transcranial magnetic stimulation (rTMS). Researchers will measure headache days and blood markers in 62 adults who had a mild brain injury 2-4 months earlier. Half will receive real rTMS and half a sham version to see if it reduces headache severity.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- repetitive transcranial magnetic stimulation (rTMS)
- What this could lead to
- If successful, rTMS could offer a new, non-drug treatment to reduce headache days after a mild concussion.
- What could go wrong
- This is a small, early-stage study with only 62 participants, and the results may not apply to everyone. rTMS may not work better than a sham procedure.

Copied word for word from the study's registry entry, so the wording is the study team's rather than ours.
Inclusion Criteria: 1. mTBI within the last 2 to 4 months according to the diagnostic criteria recommended by the WHO task force 2. age ≥ 18 years at the time of mTBI 3. Rivermead Post-Concussion Symptoms Questionnaire (RPQ) score ≥ 3 (moderate or severe problem) for subitem headache and a diagnosis of persistent PTH attributed to mTBI according to ICHD-3. Additionally, for study 2 and 3, subjects have to be stable on preventative headache medication. However, subjects are permitted to take ''as needed'' (PRN) medications throughout the study with documentation in a daily headache diary. Exclusion Criteria: 1. objective neurological findings and/or acute trauma CT scan indicating neurological disease or brain damage 2. previous mTBI within the last 2 years years leading to PCS lasting ≥ 3 months. Additionally, for study 2 and 3, 3. Pre-trauma headache frequency ≥ 10 days in average per month the last 3 months prior to mTBI. 4. past history of TMS therapy or TMS-related contraindications (pacemaker, epilepsy etc.).
