I am having regular injections but my memory is terrible or things just don't seem to be registering in my head. I have been back to the doctors the 1st doctor said it was my age (which is 56) and said it had no connection to my B12 deficiency and no matter what I said it didn't make any difference. He looked at me as if I was making a fuss over nothing On my last visit I had a memory test and passed but its not that kind of memory failure. e.g my Grandson was showing me his t-shirt with a fire engine on it which said nee-naw and I just couldn't connect and had no idea what he was talking about when it is something he says all the time and whilst this may seem amusing it happens everyday and is worrying. I was knitting which I do on a regular basis and suddenly forgot how to knit for a few seconds. I do not know what to say to my doctor next. Where do I go from here?
