Traumatic brain injury raises risk for subsequent migraine


 

Key clinical point: Patients with traumatic brain injury (TBI) were at a significantly higher risk for subsequent migraine, with the risk being even higher among patients with TBI who were hospitalized and those who had a major trauma.

Major finding: The risk for migraine was significantly higher among patients with vs without TBI (adjusted hazard ratio [aHR] 1.484), with migraine incidence being higher after major vs minor trauma (aHR 1.670) and among hospitalized patients vs patients visiting the outpatient department (aHR 1.557; all P < .001).

Study details: This retrospective cohort study included 151,098 patients with newly diagnosed TBI and 604,394 propensity score-matched patients without TBI.

Disclosures: This study was supported by the National Science and Technology Council of the Republic of China, Cardinal Tien Hospital, and Tri-Service General Hospital Research Foundation. The authors declared no conflicts of interest.
