i became unconscious on a Sunday evening and wasn't found until Monday afternoon apparently with vomit around my mouth and nostrils. later that day I was ventilated for 10 days. my question is "is it possible I have some brain damage?" (lack of oxygen) and how do I go about finding out? I have repeatedly told my gp that my brain doesn't 'feel' right, my personality has changed, my short term memory is very poor etc and I'm not as mentally quick as I used to be or sociable. its like one half of my brain no longer communicates with the other half. I'm not physically affected only mentally/intellectually. Most frustrating. This happened July 2014.
