It is estimated that traumatic brain injuries (TBI) affect nearly 1.7 million people annually in the United States.1The most commonly reported complaint associated with TBI is headache, which can result from mild, moderate, or severe injury. The International Headache Society defines post-traumatic headache (PTH) as one that develops within 7 days following TBI or after regaining consciousness following head trauma. PTH is associated with a range of comorbidities, including psychiatric, cognitive, and sleep-related issues.
