Hypersensitivity to Amylin in Post-Traumatic Headache

Summary

Pramlintide is a peptide analogue of human amylin which is a vasoactive substance involved in the pathogenesis of headache. This study investigates whether pramlintide induces migraine-like headache in people with persistent post-traumatic headache (PTH) attributed to mild traumatic brain injury (mTBI).
