Generalized Seizures

A generalized seizure starts when all areas of the brain are affected by an abnormal electrical impulse. It rapidly affects both cerebral hemispheres, and their clinical expression is consistent with substantial involvement of both sides of the brain.

Generalized seizures vary widely concerning their behavioral manifestation, from the subtle to the extreme.

Types of Generalized Seizures

  1. Absence seizure. It causes you to blank out or stare into space for a few seconds. Absence seizures are most common in children and do not cause any long-term problems. It often occurs due to a period of hyperventilation
  2. Myoclonic seizure. It is characterized by brief, jerking spasms of a muscle or muscle group along with atonic seizures.
  3. Clonic seizure. It is a rapid rhythmically recurrent seizure. Clonic seizures are characterized by repeated jerking movements of the arms and legs on one or both sides of the body.
  4. Tonic seizure. It causes a sudden tension in the muscles of the arms, legs, or trunk. Tonic seizures that occur while the person is standing may cause them to fall. After the seizure, the person may feel tired or confused.
  5. Tonic-clonic seizure. It involves twitching and stiffening phases of the muscle. It begins with a partial seizure or aura. You may also experience changes in sensation and mood.
  6. Atonic seizures. It is known as an akinetic seizure that causes a sudden loss of muscle strength.
