seizure
abnormal electrical discharge in the brain
seizure disorder

epilepsy
general term used to describe only recurrent idiopathic episodes of sudden, excessive discharges of electrical activity in the brain
partial or focal seizures
simple (LOC same)
complex (LOC impaired)
generalized seizure disorders and epilepsy
can affect the entire brain
- tonic-clonic
- intermittent
- myoclonic
febrile seizures
onset during fever greater than 38.9 deg
