Epilepsy is a common long-term brain condition. It causes seizures, which are bursts of electricity in the brain.
There are four main types of epilepsy: focal, generalized, combination focal and generalized, and unknown. A person’s seizure type determines what kind of epilepsy they have.
Different types of seizures affect the brain in different ways. For example, focal seizures affect only one part of the brain, whereas generalized seizures affect the entire brain.
To be categorized as having epilepsy, a person must experience two or more unprovoked seizures. Some people can receive an epilepsy diagnosis if they have had one seizure and a doctor thinks they have a high likelihood of having another.
