PATHOGENESISPATHOGENESIS
Seizure : Behavior Seizure : Behavior change associated with change associated with an an electrical discharge electrical discharge in cortex. Neurons recruit in cortex. Neurons recruit other neurons to fire, thus other neurons to fire, thus clinical manifestations are clinical manifestations are related to the number of related to the number of neurons affected & neurons affected & correlate with the focus & correlate with the focus & path of spread.path of spread.
Status epilepticus : Status epilepticus : recurring seizures with recurring seizures with incomplete recovery incomplete recovery between attacks. between attacks.
