Certain types of epilepsy are more likely to be inherited than others. Primary generalized epilepsy, in which the seizures begin from both sides of the brain at the same time, are more likely to involve genetic factors than focal or partial epilepsy, in which the seizures arise from a limited area of the brain.
If one or both parents have epilepsy, there is a risk of approximately 5% that it will be passed on. The vast majority of children will not inherit epilepsy from a parent. Keep in mind that many children may outgrow epilepsy, and most people who have it are able to treat it successfully and lead normal lives.
