  Seizure - Wikipedia, the free encyclopedia
Seizures (or convulsions) are temporary abnormal electrophysiologic phenomena of the brain, resulting in abnormal synchronization of electrical neuronal activity.
However, a seizure can also be as subtle as marching numbness of a part of body, a brief loss of memory, sparkling of flashes, sensing an unpleasant odor, a strange epigastric sensation or a sensation of fear.
It is still disputable whether febrile seizures have to be regarded as an epileptic disorder or not; the dispute hinges on whether fever is considered a provocant.
