Conversation: The conversation between human and AI assistant.
[|Human|] i blacked out while driving.  i have no memory from after getting on the road up until, an officer tapping on my window.  then i was in the hospital, with the worst headache i have ever had and i was very nautious.  someone said they thought i was having a seizure.  anyway to know for sure?  all tests were clear.
[|AI|]  The problem with seizure is that the tests may all come out to be normal and yet you may have the condition. There is no absolute way of knowing positively whether you have had a seizure or not, unless it was observed by someone. The description of the seizure is the best way to diagnose it. Alternate way of testing for seizure, which you may have not done because it is infrequently found, is video EEG. Here you are monitored in a room for 24 hours or as per the protocol of the testing center. During this period, your EEG is recorded continuously. The chances of getting a finding are raised. However this may also be negative.I hope that answers you best of luck Chat Doctor.
