Stopping AED before EEG?

Hi, just as my title says. My surgeon has requested that I have an EEG, but I’m currently on 2000mg of Keppra a day and looking to increase by 1000mg.
Would I get a more accurate result by stopping Keppra prior to my test? I’m concerned that I get a false negative result due to my meds??
Any advice would be appreciated!

I don't think they look for it to be positive. Mine wasn't, but I obviously have them. They never recommended me coming off of my medications to take the test. They don't have to be positive to be diagnosed with seizures. Although, you do have to have more than one seizure to be diagnosed officially.
