I.e. 'Posterior cortical atrophy' my sight is badly affected and any stress makes it much worse! At the same time it also makes most of what's happened over the last few years suddenly seems to just click into place although it's only fairly recently that it's affected me more when going somewhere different, i.e. Supermarket. I can't read prices or even recognise the picture that shows you what it is! For a while I was ok at home,but not anymore. Just trying too type this causes my sight to merge into a blurry blob. Know one seems to know much about it was only recognised in the eighties some think it's a sort of extra to the Alzheimer's,but truth be known they don't really have a clue. Looking on the bright side I may continue to know exactly what is happening to me, just as I always have done and it's more likely that the end may be because of something like Pneumonia than the Alzheimer's! That possibility cheers me somewhat as I feared the effect of not knowing my family and friends would devastate them and cause much sadness. I will just soldier on as best I can.
