The condition is very common, and has been studied a lot. Doctors only say someone has epilepsy, if that person has had at least two seizures, for which the immediate cause cannot be seen. There are also seizures which are not caused by epilepsy. There are drugs for many forms of epilepsy that make life better for those affected. In about two third of the cases, taking one drug alone can make the seizures go away. The remaining third is more difficult to treat, but in many cases, a combination of drugs can at least reduce the number of seizures.
