I have been having very random black-outs for the past year or so. I have went to two different neurologists and had MRI s and x-rays completed and everything came back normal. My blackouts last for a very short period of time and I remain conscious, but I am not sure of where or who I am. I had a broken tooth a few years back and the roots of my tooth are still in my jaw and I was wondering if it is possible that this could be causing my blackout? Thank you.
Your complaints are not described in detail to arrive at a particular diagnosis. But according to me if you are having these blackouts with amnesia of episodes and are of adult or elderly age then a possibility of Transient Global amnesia may be kept. TGA is usually due to atherosclerotic vasculature with impairment of blood supply to hippocampal region transiently. Second possibility may be of pre-syncope which requires presence of palpitation, sweating, light-headedness, visual blurring, feeling of give away and relation to standing posture. Third possibility may be of absence seizure which is more common in childhood and can be diagnosed by EEG study. In my opinion, broken tooth may not cause blackouts. Hope your problem gets an early diagnosis, and you get well soon.
