Seizures are also more likely after a hemorrhagic stroke, a stroke caused by bleeding in the brain, according to the National Stroke Association. Such seizures commonly occur within 24 hours after a stroke and affect about 5 percent of individuals who have suffered a stroke. Stroke survivors, however, can experience seizures anytime during the first few weeks after a stroke. A stroke is the most common cause of seizures in older individuals.

There are over 40 different types of seizures, states the National Stroke Association. They involve symptoms such as tingling sensations, going blank for a few moments, shaking or trembling, spasms or convulsions, and losing consciousness. They are a sign of some type of brain damage and are caused by disorganized electrical activity in the brain.
