There is a possibility of recurrence after epilepsy is cured, and the reasons include not stopping the medication in a gradual and orderly manner, taking medications that cause neuronal excitation, and secondary brain damage. 1. Failure to stop medication gradually: some epilepsy patients have no seizures for 2-5 years after systematic oral antiepileptic drugs, and the electroencephalogram review is normal, at this time, the medication can be gradually reduced or even stopped. Discontinuation of medication is a gradual process and may take a long time, if the process of discontinuation of medication is faster, it may lead to recurrence of epilepsy. 2. Taking drugs that cause neuronal excitation: for example, aminophylline and levofloxacin. Some patients with epilepsy are clinically cured after drug treatment, but the use of drugs that cause neuronal excitation may lead to epileptic recurrence. 3. Cerebral injury: epileptic patients cured, but cases of purely cerebral situation, such as sudden cerebral hemorrhage, cerebral infarction, traumatic brain injury, secondary brain injury, it is likely that seizures will occur. Epilepsy treatment whether recurrence can not be generalized and, it is recommended that epilepsy patients in the physician’s guidance to reduce or stop the drug.
