How many types of seizures do we have?


Seizure types

There are many types of seizures. Most seizures last from 30 seconds to two minutes. A seizure that lasts longer than five minutes is a medical emergency.

Doctors generally classify seizures as either focal or generalized, based on how and where abnormal brain activity begins. Seizures may also be classified as unknown onset, if how the seizure began isn’t known.

Focal seizures result from abnormal electrical activity in one area of your brain.

Seizures that appear to involve all areas of the brain are called generalized seizures. Different types of generalized seizures include:

  • Absence seizures.
  • Tonic seizures.
  • Atonic seizures.
  • Clonic seizures.
  • Myoclonic seizures.
  • Tonic-clonic seizures.
