Having a first seizure at 69 is more common than many people realize. At that age, the most frequent cause of new-onset seizures is a stroke, which can disrupt the brain's electrical activity.

Other possible causes in older adults can include:

- Brain injury or structural changes in the brain
- Tumors
- Infections or illness causing high fever
- Low blood sugar
- Unknown causes (called idiopathic seizures) It's worth knowing that having a single seizure doesn't automatically mean a person has epilepsy. A proper evaluation by a neurologist is the best next step to identify the cause and determine the right course of action.

If this has happened to you or someone you care about, getting medical attention quickly is really important — especially to rule out anything that needs urgent treatment.
