Antiseizure medications (ASMs) reduce abnormal neuronal firing and prevent or limit seizures. They do not necessarily correct the structural, genetic, metabolic, or immune cause of epilepsy. That distinction explains why a patient may remain seizure-free while taking medication but still need ongoing treatment, safety counselling, and follow-up. The medication is being used for a specific seizure problem. Seizures may be focal, generalized, of unknown whether focal or generalized onset, or unclassified. The current International League Against Epilepsy classification also separates features that change management from descriptors that simply describe what the event looked like.
