What are the different kinds of seizures?

Seizures are divided into two major categories - focal seizures and generalized seizures. However, there are many different types of seizures in each of these categories. In fact, doctors have described more than 30 different types of seizures.

Not all seizures can be easily defined as either focal or generalized. Some people have seizures that begin as focal seizures but then spread to the entire brain. Other people may have both types of seizures but with no clear pattern.

Seizures can be classified as focal or generalized. Focal seizures begin in one area of the brain and may or may not spread to other areas. Generalized seizures are the result of abnormal neuronal (nerve cell) activity on both sides of the brain from the beginning of the seizure.

About 60 percent of people with epilepsy have focal seizures.
