Classification of Epileptic Seizures by UCBEAction
Diseases of the brain characterized by an enduring predisposition to generate epileptic seizures are collectively called epilepsy.
Seizures can also occur in people who do not have epilepsy for various reasons including brain trauma, drug use, elevated body temperature, low blood sugar and low levels of oxygen.
A first seizure generally does not require long term treatment with anti-seizure medications unless there is a specific problem on either electroencephalogram or brain imaging.
Electroencephalography is an electrophysiological monitoring method to record electrical activity of the brain.
Anticonvulsants are a diverse group of pharmacological agents used in the treatment of epileptic seizures.
5–10% of people who live to 80 years old have at least one epileptic seizure and the chance of experiencing a second seizure is between 40% and 50%.
About 50% of patients with an unprovoked apparent "first seizure" have had other minor seizures, so their diagnosis is epilepsy.
Epilepsy affects about 1% of the population currently and affected about 4% of the population at some point in time.
