Can hormones cause seizures?
Yes, hormonal changes can trigger seizures in some people with epilepsy. This is particularly noticeable during the menstrual cycle, when levels of estrogen and progesterone naturally rise and fall.
Estrogen has pro-seizure effects and can excite neurons in the brain, increasing the likelihood of seizures. Progesterone, on the other hand, has anti-seizure effects and can inhibit brain activity, reducing seizure risk.
When progesterone levels drop or estrogen levels rise during certain phases of the menstrual cycle, your seizure threshold may change. This is why some people experience more seizures or more intense seizures at specific times during their cycle.
Catamenial seizure patterns most commonly occur three days before menstruation starts and three days into the period, when progesterone levels are at their lowest.
One MyEpilepsyTeam member shared, "I started my period when I was 12, and I had my first seizure that same day. The seizures would last until my period stopped, then they would start all over again next month."
If you notice a pattern between your hormones and seizures, tracking them in a seizure diary can help you and your doctor identify triggers and adjust your treatment plan accordingly.
