Estrogen fluctuation affects epileptic seizures

In more than a third of women with epilepsy, seizures fluctuate across the menstrual cycle, due in part to continually fluctuating effects of estrogen on the neural circuitry in the hippocampus, a region of the brain involved in learning and memory - and in epileptic seizures. Northwestern University...
