Novel biomarker for post-traumatic headache investigated

Visual evoked potentials (VEP) show promise as a way of identifying youths who are at high risk of prolonged post-traumatic headache (PTH) after concussion, according to preliminary data presented at the AHS 2021 virtual conference.

As many as 1 in 5 youths in the USA report being diagnosed with at least one concussion. About 80% experience headache after concussion, with 25% reporting headache that persists for 1 month or more.
