For the most part estrogen makes seizures worse and progesterone can help them. It is known as catamenial epilepsy when hormones are a major trigger. I have posted a lot on hormones & epilepsy in the past so if you go and search my past posts in the epilepsy forum you will find a lot of information.
Hope it helps.
For me it seems like Progesterone and Estrogen BOTH make my seizures worse! I get seizures when I get my period, but also right in the middle of the month when Progesterone levels are usually increased.
