PoAs can only be set up will the person living with dementia has mental capacity so it is a good idea to get themselves up early but not to activate them till necessary.
You could suggest that you both do them as you never know what's round the corner for either of you.
As far as driving is concerned, it is his reactions to the unexpected that might cause a problem - a child running into the road for instance. And, the DVLA will have to be informed if he gets a diagnosis.
I suggested LPA for both of us when the Bodach was first showing signs of ‘forgetfulness’. The lawyer came to the house ( on a good day), and was happy to start proceedings, however, when the Memory Clinic where the Bodach had gone for assessment were contacted, they said he did not have capacity, so it was just set up for me.
Our bank accounts etc were in joint names, so no issues there, and I was able to make decisions about his medical care, like a DNR and palliative care only ( he had cancer), though I have heard of people who have had problems because of a lack of LPA.
