Both my stepmother and my father were diagnosed with 'memory problems' 6 years ago. My stepmother passed away 18 months ago. Dad has vascular dementia, and is living in sheltered accommodation 'independently'. I got some new glasses a couple of years ago - they cost £200. Shortly after I got them, they completely disappeared, and I had to go back to my old ones while I searched for the new ones. After about 6 months of searching, I gave up and went and ordered another pair. A couple of months after that, I was at the Chinese restaurant with my parents. When we were handed the menu, my stepmother said 'I don't know what's wrong with these glasses - they're completely useless!' I said "Really? Let me try them!" Of course they were my old disappeared glasses, all bent up, but I could see perfectly through them! I got my Dad a multi-coloured 'thread' to string his glasses round his neck. If they get lost they show up, but they do tend to collect food at meal times on the lenses! Dad has just started to suffer delusions. Today he thinks that he is going to be made King, and he doesn't want the responsibility.
