I have been on medication for seizure for about 10 years now. Had brain fog years ago which led me to neurologist. She did EEG and interpretation was "abnormal eeg study due to the presence of epileptiform discharges exacerbated by hyperventilation. I have never had any symptoms at all related to seizures except brain fog. It did not come and go quickly, I would feel like i was in a fog for months with a few times where I felt fine. My question is 1- Are epileptiform discharges seizures? 2- I have been on lamictal for years on and off, last 3 years straight. Do epileptiform discharges need to be treated? I have never had a typical seizure. Never lost consciousness in my life for any reason, never spaced out and forgot where i was.
