There are six types of generalized seizures. These seizures produce electrical impulses throughout the brain.
Grand Mal which can results in loss of consciousness, body stiffening, violent jerking and falling.
Absence seizures which can cause a short loss of memory and cause a blank stare by the person having the episode, generally a child.
Myoclonic seizures which cause brief jerks of the body, sometimes described as brief shocks. These happen on either sides of the body.
Clonic seizures which causes body jerks on both sides of the body at once.
Tonic seizures stiffen the muscles.
Atonic seizures give a sudden loss of muscle tone in mainly the arms and legs and can lead to a fall.
