Chronic post-traumatic headache (PTH) always arises from some sort of head injury such as mild traumatic brain injury or concussion. The terminology and definitions for these injuries remain controversial and continue to evolve. This article reviews and updates current terminology and definitions for these head injuries, along with current concepts of pathophysiology. The second portion of this article considers the persistence of the other symptoms associated with chronic PTH, which constitute the post-concussive disorder. PTH is the most common symptom after a head injury, but post-concussive symptoms often complicate the clinical picture and must be considered in the overall management of the chronic PTH patient.
