A seizure is abnormal electrical activity in the brain. When two or more seizures occur, it is considered a seizure disorder, also known as epilepsy. While there are many different types of seizures, the main categories are:

  • Generalized seizure—activity occurs throughout the brain
  • Partial seizure, also called a focal seizure—begins within certain areas of the brain
