What Are The Major Types Of Seizures?

Clonic Seizures

A clonic seizure is a type of seizure where an individual has an involuntary jerking in parts of their body. These types of seizures can be focal, where only one part of the brain is affected, or they may affect the entire brain. The jerky movements seen in an individual affected by a clonic seizure are the result of repeated stiffening and relaxing of the affected muscles. Clonic seizures tend to last for a duration of between a few seconds and two minutes. Clonic seizures produce movements that are more sustained and regular than those in a myoclonic seizure. Clonic seizures are rare but can occur in individuals of all ages, from infancy to old age. A clonic seizure in a young infant can easily be mistaken or dismissed as the child being jittery. The movements that occur in a clonic seizure cannot be stopped through restraint of the affected limbs or part of the body the way jitteriness can. A clonic seizure is diagnosed through the use of observation, standard EEG, and video EEG.
