If there was one thing I wish I had anticipated as I learned about the progression of Alzheimer's. it would have been regards falls. I chose to learn in my own way. My wife had a number of falls before I realised that she lost her 'spatial awareness': meaning she lost the ability to judge distances and heights. On reflection had I been more aware, I may have prevented the fall that landed her in hospital. Everything after that, was down hill. Now I'm more acutely aware what it must be like to suffer so. In the past few days after my recent falls, I suffer with double vision. Yesterday my GP arranged an urgent appointment at A&E for me. After five hours I'm told my eyes are OK and was given glasses to wear, with a patch on one lens. Now I know the scary feeling of seeing two of everything. I'm told to expect it to get better and attend a special appointment in three weeks time. To type this I have to be close up to the screen. Now I have some idea of what it like in a world where people and objects move up and down in twos and can't judge distances.
