How common is this in adults? And what does it mean that I have this? As a 37 year old female, this just showed up in a sleep study. I have one neurologist telling me it could mean I'm having seizures that I don't know I'm having and that I should get an EEG done. I have another one telling me that it just means that I have benign abnormal EEG activity and that even if I get the EEG done it will just confirm that I have this activity but not that I'm having seizures. I have not had any seizures to my knowledge. I'm trying to figure out whether I should get the EEG done or not. In trying to look up information on the web it is all about children and I can't find any pertinent information for me. Can you help?
