7 Diversity of Epilepsy Pathogenesis Over 400 genes have been implicated in human epilepsy, and abnormal gene products can disrupt neural circuit function at various cell biological levels. Rao VR, Lowenstein DH. Epilepsy. Current Biology 25, R733 R752, 2015
8 Ongoing Transformation in Epilepsy Therapy Discovery Legacy Model Target seizures Unbiased to epilepsy mechanism May treat only certain seizure types in an epilepsy syndrome Unlikely to impact comorbidities Not disease modifying Emerging Model Target epilepsy Informed by pathophysiology Likely to treat all seizure types in a syndrome May impact comorbidities May be disease modifying, but not necessarily
