Answer

Although clinically significant cerebral edema can occur after anterior circulation ischemic stroke, it is thought to be somewhat rare (10-20%). [1] Edema and herniation are the most common causes of early death in patients with hemispheric stroke.

Seizures occur in 2-23% of patients within the first days after ischemic stroke. [1] A fraction of patients who have experienced stroke develop chronic seizure disorders.
