For months I've had olfactory hallucinations of ammonia after running (not every run but most). Within the last month, I've noticed on 3 separate occurrences the same smell while not running. The last occurance before the hallucination I had a bit of vertigo as well. I've seen a neurologist, my eeg was normal (however I had quire a bit of twitching during the strobe portion) and my MRI was normal. The neurologist thinks I'm having simple partial seizures in the temporal lobe and I'm seeing him next week to discuss medicine. I'm concerned with the fact that the olfactory hallucinations seem to be getting more frequent. Is this common with simple partial epilepsy?
