I had died, and did not have oxygen my brain to what I am told is six minutes. I, within the same day, had 14 seizures, cardiac arrest, and flatlined twice. The brain scans came back clear (this was 3 years ago), but I think I have brain damage, and am unsure. My main focus was on the oxygen deprivation part. Do you think it could be possible? And if so, how could I check? Without, like, a questionnaire, as I do not remember much of myself beforehand to compare myself to.
