Thanks ladies! Yes, @primek, it also scared crap out of me when G P told me. I remember my dear great grandmother, she had totally lost the plot but was mid eighties, my mum is 79 and great. I came home and got back into fish oil and b vitamins, have a fairly healthy diet, lots of fruit, veg, fish and limuted red meat. Cholesterol used to be high but was okay on Tamoxifen, will have to monitor it now i have changed medication as that is another risk factor!! I have been quite accepting that life is different than it used to be but didn't really think i would be worried about cognitive decline just yet!! Oh well, onward and upward !!!
