BackgroundOften concussion/mTBI triggers a chronic headache syndrome called persistent post-traumatic headache (P-PTH) that can last from months to years post-injury, and produce significant disruption of childhood education, social interaction and development. Although prevalent and highly disabling, P-PTH is underrepresented in headache and pain research and lacks clear definition and pathophysiology. Clinical presentation of P-PTH frequently resembles that of other headache disorders, like migraine, yet the pathophysiological mechanisms are distinct and not fully understood, making the disorder difficult to treat in the clinical setting.MethodsIn a retrospective analysis of 1506 pediatric patients attending Boston Children's Hospital clinics, demographic trends, symptom features, and the influence of sex on clinical presentation of PTH are presented. We compare clinical characteristics of P-PTH with a published cohort of migraine patients to evaluate the clinical features that are unique to P-PTH.ResultsFindings show that despite equivalent representation of sex in the clinic, P-PTH is expressed more in females than males and is weighted towards somatic symptoms. Relative to migraine, PTH is less associated with a family history of headache.ConclusionsThe ability to identify persons with PTH can help manage risk factors and identify persons likely to develop persistent post-concussion symptoms.
