Subject: Re: What does "Borderline Epileptic EEG" mean? I've just had a verbal (telephone) report on my EEG from the neurologist. I have some abnormalities and the EEG was borderline epileptic. Unfortunately he didn't have time to go into details (and I was more concerned with whether he was going to let me go flying!), but said he'd like to do a sleep EEG as a follow up. As it will be at least a couple of weeks before my GP gets the written report, I'm left puzzling over what he meant by "borderline epileptic". Any thoughts, please? Stuart
the changes on an EEg which suggest the presence of epilepsy are sharp waves. Sometines these waves are simply not large enough , sharp enough, or the typical shape to be absolutely sure that they represent an abnormality. On the other hand it is not possible to simply ignore them. In this case the EEg is termed borderline and a repeat EEg is advised. Sleep or sleep deprivation tends to enhance epileptic changes in the EEG making the test more sensitive and specific.
