Can anyone give me some info on the memory test? My dad has had alzheimers for the last few years & he goes to see a dementia dr every 6 months or so. He has been on the same tablet since diagnosis & his results have been stable sitting about 25/24. We were advised that the tablets usually stop working from about a year to 18 months & since about June we have seen a big decline with his memory, communication and reading ( its actually been quite scary seeing how quickly it has happened)! He went for his review last week and scored 17. My mum knew he was getting worse but I dont think she quite expected that much of a change & he had no idea at all that he was worse & was absolutely devestated when the dr told him the results! What I was wondering is does anyone have an idea of the scale. Would 17 be classed still as early stages alzheimers & how low do people in late stages get? My mum never thought to ask the dr these questions as the pair of them were just in shock! The dr is changing my dad from the tablets & on to the patches. Can anyone tell me how people have got on with these? Thanks for your help!
