I am learning that I have increased my short term memory loss since I was last hospitalized over a year ago. I wonder if I have sustained brain damage because I am so forgetful nowadays. When I was in a drug-induced coma, can it cause brain damage? Or if found unconscious at the scene, could I have already experience with lack of oxygen to the brain? I'm trying hard to accept this fact and I find it disturbing and curious at the same time cuz I want to learn more about loss of memory after a coma. Does anyone know what I'm talking about?
