Hypersensitivity to Opening of BKCa Channels in Post-Traumatic Headache

Hypersensitivity to Opening of BKCa Channels in Post-Traumatic Headache: A Randomized Clinical Trial

NCT05378074•Danish Headache Center

Summary

The aim is to investigate whether opening of large conductance calcium-activated potassium (BKCa) channels induces headache with migraine-like features in people with persistent post-traumatic headache (PTH) attributed to mild traumatic brain injury (mTBI).
