There are two possible scenarios of seizures after the cause of secondary epilepsy is removed. In the first case, the effects on the central nervous system can disappear, brain function gradually returns to normal, and seizures no longer occur. For example, in some patients with viral meningoencephalitis, the onset of the disease is often characterized by impaired consciousness and seizures, and after adequate treatment and functional recovery, seizures do not occur even without antiepileptic drugs. In the second case, the lesion of the central nervous system has been irreversible, and even if the initial cause has been lifted, the damaged brain tissue still insists on abnormal discharges and seizures still occur intermittently, in which case it is necessary to insist on medication. Therefore, in clinical practice, after the cause of secondary epilepsy is removed, the patient should still continue to take antiepileptic drugs for a period of time under the guidance of a physician and closely observe the changes in the condition. If the doctor determines that the patient may fall into the first category, he or she may try to discontinue the medication, and if there are no seizures after discontinuing the medication, the discontinuation is considered successful, and the doctor can therefore conclude that the patient falls into the first category (discontinuable). If discontinuation fails, or if the doctor determines that the patient is in the second category, the patient should stay on the medication, usually for a long time, even for life.
