Post-stroke convulsions are commonly caused by seizures secondary to cerebral infarction, and the elderly are the age at which cerebral infarction is most likely to occur and most likely to be combined with secondary epilepsy. The site of cerebral infarction has a significant effect on seizures, with cortical and subcortical infarcts, especially deep infarcts that ripple from the cortex to the subcortex, more likely to trigger seizures. Epilepsy can occur in different periods of cerebral infarction, and epilepsy in early cerebral infarction is mainly due to acute circulatory disorders, ischemia and hypoxia causing brain tissue edema and metabolic changes. Patients recover from this time relatively quickly, and generally do not need lifelong medication. If a patient has convulsions during the recovery period of cerebral infarction, secondary to epilepsy, at this time, seizures are caused by deposition of hemoglobin, ferritin and other substances. In this case, anti-epileptic drugs may be needed to prevent re-seizures. Commonly used anti-epileptic drugs include carbamazepine, oxcarbazepine, sodium valproate, etc. Specific treatment should be given at a specialist hospital under the guidance of a specialist and oral anti-epileptic drugs.
