Your doctor will take a detailed history from you and observers to help determine if you have
epilepsy. The history may include questions about:
- Your past medical history
- Family medical history
- Any and all medications you take
- How were you feeling before the seizure?
- How old were you at the onset of the condition?
- Was there any warning?
- What did the seizure look like, or what were you told it looked like?
- Were there any symptoms after the seizure?
- How long did the seizure last?
- How many seizures have you had before?
- After the seizure, did paralysis, twitches, confusion, slowed responsiveness, urine incontinence, or tongue biting occur?
Your doctor may perform a physical exam. Special attention will be given to your nervous system. Tests will be taken to see if you might have epilepsy, and if so, what type of seizures you have.
