Common Stressors
Concussion and post-traumatic headache
How head injury and migraine interact, and why prior migraine can slow recovery.
4 min read · 5 research sources · Based on the Mastering Migraine courses by Dr. Adam Harcourt

Headache is the most common symptom after a concussion, and it often looks just like migraine 1.
The two-way relationship
- Concussion can bring on migraine-like headache in people who never had it before, or make existing migraine worse 1,2.
- Pre-existing migraine is associated with more symptoms and longer recovery after concussion 3.
- Post-traumatic headache involves changes in autonomic function similar to migraine 4.
Sports and head injury
Migraine and other headache disorders are closely tied to sports-related concussion, and pre-injury migraine can delay return to school and sports 2,3.
How it is evaluated
Concussion often affects the eyes and balance system. The Vestibular/Ocular Motor Screening (VOMS) is one tool used to check for these problems after concussion 5. Dr. Harcourt’s exam includes eye movement, vestibular and balance testing.
Treating them together
Because concussion and migraine share mechanisms, Dr. Harcourt addresses them together, with an emphasis on neurological rehabilitation. Any significant head injury with severe headache, vomiting, confusion or weakness needs emergency care first.
