... Genetics is believed to play a role in most forms of epilepsy. However, perhaps surprisingly, most people with epilepsy do not have any affected relatives. Current scientific evidence suggests that the role of genetics in epilepsy is complex – many genes with a small or modest effect on risk are lik ...
