Research project

Epilepsy affects approximately 1–2% of the general population and there are gender differences in the expression of the disease and the impact on health. Catamenial Epilepsy (CE) is a condition in which seizures, either the frequency or severity of seizures, are increased or occur during a certain phase of the ovarian cycle (OC). CE is seen in almost 40% of women with epilepsy, and it is a very important medical problem. Catamenial seizures are influenced by the cyclical sex steroid hormone changes during OC where estrogen is thought to be proconvulsive, increasing epileptiform discharges and seizure frequency; whilst progesterone is thought to be anticonvulsive, reducing epileptiform discharges and clinical seizure occurrence. In addition to seizure clustering in relation to sex hormones, a relationship with circadian rhythms is also recognized. Epileptic seizures do not often strike randomly, but may occur in circadian patterns. The daily periodicity of seizures suggests a direct circadian influence on seizures of limbic origin where melatonin modulates circadian biorhythms and depresses brain excitability, prevents seizures and reduces GABAergic function.
