My OH was diagnosed almost 2 years ago, and I wondered the same. It seemed important to me at the time to know 'what stage he was at' -but, do you know - it isn't important.
Learning to cope with your feelings and his life is what is important - and getting the right help. If you don't ask for it, you won't get it, and it is very varied, some more useful than others.
Get yourself a Carers Assessment - if you have not done so. I didn't think I was bothered at first - but it has been the best thing I have done. They are skilled people and pick up on what you say and come up with innovative ideas.
I was bemoaning the fact that I will shortly have a grandchild born over 400 miles away and my partners dementia would mean I would not be able to see my new grandson. The lady doing the assessment, asked if I skyped and I said my computer was old, and did not - she emailed me this week saying I was getting funding to by a new one - how brilliant, because I could never have afforded one.
So back to your original question - the 7 stages of dementia are very rough, people go through them at different rates, and they affect people very differently.
I have found it easier to think ( simplistically) that there are 3 stages - that the early stages lead to diagnosis, then its middle stage when they are still functioning, but not well and cannot do money, read books, follow a film, converse reasonably, and later stage when they need 24/7 care that is beyond what a family member can provide at home.
I am sure other people on here will have some alternative ideas. but Good Luck[/QUOTE
So pleased that you are getting a new computer, well done. Xxx
