BDNF and photosensitive epilepsy: While no group-level differences in serum BDNF concentrations were observed, BDNF levels correlated with disease duration and seizure latency exclusively in the PSE group.<h4>Discussion</h4>Importantly, as samples were obtained during follow-up rather than the acute post-stroke phase, our results indicate an involvement of the miR-10b-5p/BDNF axis in long-term post-stroke remodeling or general PSE susceptibility rather than a predictive biomarker.
