Sorry, but why does it matter which dementia??
because every one of them usually transpires totally differently, although everyone is unique and not two patients the same regardless of type of Dementia. However it is a good guideline to enable you to understand the illness. Read up on everything to do with his Dementia.
Have you got an Admiral Nurse in your area, if not you can telephone Dementia UK and they will answer every single question you have. Join a carers support group, get all your paperwork in order and ask for help. Specific help is best, people then know how they can support you. Live in your husbands world, that is all that is all he knows and you will never convince him otherwise. Never argue distract. Walk out of the room if you feel stressed or ready to blow, you will feel awful if you do. So many groups on line too including Talking Point on the Alzheimers Society, which is excellent. Good luck, it is not easy but I am sure you will do it with love.
