Complex Partial Seizure

What Is It?

A complex partial seizure is a partial seizure which causes an alteration or loss of consciousness. In general, partial seizures, also known as focal seizures, involve only a part of the brain at one type, in only one hemisphere. Whereas a simple partial seizure does not cause any change in the level of consciousness of the patient during the seizure, a complex partial will lead to some alteration in the level of consciousness of the patient during the event. These patients lose consciousness at least partially and generally have no memory of the events after the seizure.

As with all partial seizures, an electroencephalogram during such a seizure will only demonstrate seizure activity over a part of the brain, in contract to a generalized seizure which involves the whole brain.
