What do seizures mean after a stroke?
If you’ve had a stroke, you have an increased risk for having a seizure. A stroke causes your brain to become injured. The injury to your brain results in the formation of scar tissue, which affects the electrical activity in your brain. Disrupting the electrical activity can cause you to have a seizure.
