If a patient with cerebral infarction suffers from convulsions, life expectancy will not be affected if treatment is timely. If the symptoms are more serious, they may be life-threatening, but it is not certain how long the patient can live. If a patient with cerebral infarction has convulsions, it may be caused by low calcium, and the symptoms can be relieved after timely treatment with calcium supplementation, which does not affect the life expectancy. If it is caused by secondary epilepsy, antiepileptic drugs can be given to treat the symptoms, and if the antiepileptic drug treatment is well controlled, it will not affect the life expectancy. If the secondary epilepsy is a grand mal seizure, and the response to drug treatment is poor, it is easy to develop into epileptic status epilepticus, which can be life-threatening at any time if it cannot be effectively controlled. How long a patient with cerebral infarction lives with convulsions is related to the cause of the convulsions, the severity of the disease, and the treatment, and cannot be generalized. It is recommended that patients seek medical treatment in a timely manner to avoid the worsening of symptoms and the emergence of danger.
