Hello
@Acelen and welcome to the forum
Dementia is a general diagnosis and Alzheimers is just one form of it, but there are lots of other types of dementia - vascular dementia, Lewy body dementia and frontotemporal dementia are all other common types of dementia
I think that what you are actually asking though, is does dementia always progress? And Im afraid that it does. Sometimes it progresses very slowly and sometimes it progresses quickly, but whichever type of dementia you have, it cant be cured or halted.
So the answer is to plan ahead. Organise your Power of Attorney and your will.
Do you have someone (a spouse or family member) who you trust and can follow their advice when things start to become more difficult?
Apart from this, enjoy things that you can still do and be prepared to do other things that maybe you hadnt previously considered
