[|Human|] I had a blackout Wed. a week ago and fell head first going up the stairs of the metro station in Paris,(was not on the menu), hit my hesd, hurt my knees and ribcage and ended up in the hospital it was the second time in 6 months that i lost sudden consciosness & fell forward just to come to myself when hitting the floor. in this case the concrete. Had 6 stitches on the forehead, very fashenable in Paris.... My doctor here in sfo put me on a heart monitor for the rest of the month....I take Atenolol, 025mg for a long time. Should i ask for a Brain Scan to see if this was due a stroke??? thanks you
[|AI|]  Hello! Thank you for asking on Chat Doctor! Regarding your concern, I would like to explain that there are many causes of loss of conscience. The two most common reasons are : 1. A cardiac arrhythmia. I agree with your doctor about the heart monitor, to exclude this possibility. 2. Epilepsy seizures. To exclude this possibility it is necessary to consult with a neurologist for a careful physical examination and perform an EEG. A brain MRI may be needed to exclude possible intracranial causes like; a small stroke (vascular epilepsy), a tumor, etc. Hope to have been helpful! Best wishes,
