Just because you have a parent, sibling, cousin or aunt who has epilepsy doesn’t necessarily mean you’ll have it also.
In fact, if you have a close relative with epilepsy, the chance of you having epilepsy is only about 2-5%, depending on the specific type of epilepsy.
The risk in the general population is about 1-2%.
On the other hand, there is a 92-98% chance for the close relative of someone with epilepsy to NOT have the same condition!
