Children with genetic risk factors for migraine may experience more severe headaches after a concussion, according to a University of Calgary-led study released on Apr. 15. The research, led by Dr. Serena Orr and Dr. Keith Yeates, followed over 600 children aged 8 to 16 for six months after they presented with concussion symptoms.
The findings are significant because prolonged post-concussion headaches can impact a child's recovery and daily life, including school performance and social interactions. The study is the first to examine specific genetic factors related to migraine and their connection to outcomes following a concussion.
Researchers assessed migraine genetics through family history reports, polygenic risk scores that measure cumulative genetic risk, and the presence of certain gene mutations. They found that both a family history of migraine and mutations in four specific genes were linked with an increased likelihood of experiencing more severe headaches after concussion.
Dr. Serena Orr said, "There's a signal here that having migraine genes might increase your risk of having more headaches after concussion, which we know is associated with worse long-term outcomes after concussion." Beyond headache pain itself, symptoms such as blurred vision, balance issues, and dizziness may also be connected to migraines in this context.
The researchers suggest these insights could help healthcare providers identify patients who need closer monitoring or tailored treatment following head injuries. In the future, rapid genetic testing might enable personalized care for those at higher risk for post-concussion headache.
The next phase will involve replicating these results in other groups including adults. The study's authors say this work marks an important first step toward understanding how family history and genetics influence recovery from concussions.
