I came on here about a year ago worried after my doctor tested my memory and found the results poor. I have continued to struggle with things over the course of the year suffering from confusion, increasing forgetfullness, having problems holding a conversation as I cant always remember words. I have had numerous blood tests. At one point my B12 was low and the doc thought this might have been the cause, but B12 levels have returned to normal. I had a CT bran scan in September and various xrays to rule out other courses. I am on medication for PTSD and this was thought to have been a possible cause. I am male and 56 years old and today was told that my most recent MMSE test scored at 20 and was causing my GP concern for someone of my age and educational background. ( I was a mature student and gained my Honors degree 1st class in 2003 and now struggle to even read the newspaper.) I have to have another chest x ray and more blood tests but I am getting really worried about this and find it hard to talk to anyone about it. Can anyone give me some positive slants on all this ?
