It is estimated that traumatic brain injuries (TBI) affect nearly 1.7 million

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.2

The prevalence rate is 47% to 95% in patients with mild TBI, and 20% to 38% in patients with moderate to severe TBI.1 “Mechanisms are unclear and likely multi-factorial,” Vernon B.
