There are many factors that affect the survival of adults with epilepsy, closely related to the type of epilepsy, seizure frequency, and duration of the disease, and cannot be generalized. In most cases, as long as epilepsy is well controlled it generally does not affect life expectancy. However, persistent status epilepticus can cause death in patients with frequent seizures, non-recovery of consciousness between seizures, or convulsions lasting more than half an hour, which are very critical and may endanger the patient’s life. If treatment is not timely, the patient may suffer respiratory and cardiac arrest at any time. In addition, the survival of patients with epilepsy depends on whether comorbidities will develop. There is also a risk to life if the seizure process leads to aspiration pneumonia, fractures, etc. To avoid persistent seizures, patients need a continuous, full course of medication and must not stop taking it on their own to prevent adverse consequences.
