Specific pre-injury migraine characteristics associated with worse concussion outcomes

Individuals with a retrospectively reported history of migraine recalled worse concussion outcomes than those without a migraine history. Additionally, more unfavourable recalled pre-injury migraine characteristics were associated with reports of more adverse post-concussion outcomes. These findings highlight the potential value of assessing individuals' experience with pre-injury migraine when evaluating post-concussion challenges, and the need for future research to examine these relationships using longitudinal designs and objective clinical measures.
