Convulsions are a post-infarction comorbidity and are divided into acute phase convulsions and stable phase convulsions. Some patients have only one convulsion and may not have further seizures; some patients have frequent convulsions. According to the condition, its treatment is as follows: 1. If the patient has only one convulsion: observation can be carried out without immediate medication and timely prevention is required; 2. If the patient has multiple convulsions: antiepileptic drugs can be considered to avoid new injuries caused by convulsive seizures; 3. Active treatment of the primary stroke requires antiepileptic treatment. The length of treatment is related to the severity of brain symptoms and the number of EEG epileptic waves.
