Atonic. Loss of muscle tone. Generalized Seizures. There are six types of generalized seizures. The most common and dramatic, and therefore the most well known, is the generalized convulsion, also called the grand-mal seizure. In this type of seizure, the patient loses consciousness and usually collapses.he loss of consciousness is followed by generalized body stiffening (called the tonic phase of the seizure) for 30 to 60 seconds, then by violent jerking (the clonic phase) for 30 to 60 seconds, after which the patient goes into a deep sleep (the postictal or after-seizure phase).
Any normally healthy person can have a single seizure under certain conditions. For instance, a sharp blow to the head may cause a seizure. Having one seizure does not always mean that a serious health problem exists. But if you have a first-time seizure, you should be checked by your doctor. It is important to rule out a serious illness that may have caused the seizure. Fever seizures (febrile convulsions) are the most common cause of a single seizure, especially in children.
