When EEG test results are not that normal what does that mean?

Question

And can it prevent you from driving

Answer 1

It means you need to ask your Doctor what t do about it before you die from a heart attack!

Answer 2

 can it prevent you from driving? Depends on the state, some are automatic while others are self report. 

Abnormal, not normal, covers a lot of ground by the way and it does not always mean something seriously is wrong.

Answer 3

Yes it can prevent you from driving. It means that there is some issue with your brain and further investigation would be required to see exactly what the issue is and how it may affect you.
