1 When medication isn t quite enough. Alternative and complementary treatment strategies in epilepsy Topics to be addressed Hormonal progesterone Diet Atkins, ketogenic Supplements Tina Shih, MD UCSF Epilepsy Center May 22, 09 Omega-3 fatty acids Catamenial epilepsy ovulatory cycles Reproductive hormones have neuroactive properties Progesterone: seizures Estrogen: seizures Neuroactive reproductive hormone levels vary during the menstrual cycle Serum hormone levels E P Phase Estradiol pg/ml Progesterone ng/ml C2 F O L C1 M Day of cycle Herzog AG et al Epilepsia
