Sex differences in photophobic behaviors following cortical spreading depression in rats

Altogether these findings highlight the importance of considering sex-specific differences in developing therapeutic strategies for the treatment of migraine. We report for the first time a complete time course analysis of migraine-related responses, providing a comprehensive overview of the dynamics involved. The results suggest that potassium chloride-induced cortical spreading depression may offer a valuable model for studying the underlying mechanisms and sex differences of photophobia in migraine, aiding in the development of targeted treatments.
