Serious Complications Linked To An Embolic Stroke

Seizures

Over one-fifth of all patients who survive a stroke will experience one or more seizures. A seizure is a medical event where there is irregular and abnormal electrical activity in a patient's brain that causes specific symptoms. Some individuals describe what is going on in the brain during a seizure to be similar to an electrical storm with disorganized electrical activity. Common behaviors that occur in individuals who experience a post-stroke seizure are body convulsions and spasms. Post-stroke seizures usually happen sometime within the first few weeks following a stroke. Patients who have had an embolic stroke are at an increased risk of having seizures because regular electrical activity in the brain is unable to occur in the presence of scar tissue. The tissue injury that occurs in an individual's brain when they have an embolic stroke can cause the body to form scar tissue in the affected part of the brain. Scar tissue can interrupt the healthy electrical activity in the individual's brain, and this can trigger a seizure.
