My husband has vascular dementia and rapidly declining. What I find so hard is the difference just a few hours can make. This morning he couldn't walk, talk , eat or drink. He made no sense at all and was shaking all over. I called the g.p. but by the time she came after lunch he was coming out of it and saying a few simple words and walking a little. I feel I shouldn't call for help but it's frightening as I'm on my own with him most of the time. Does anyone else have so many changes in the same day? If so, how do you cope?
