I also think dementia suffers still feel emotions, Lyn. What they lose is the ability to express them as dementia progresses. Then I did read about this somewhere, that they stay with them until the end.Oh yes Loo! It takes some practice and trial and error-and some times it doesn't work-BUT it's worth having a go It's all to do with the emotions that Dementia sufferer's still feel-I think anyway.
Even as dementia progresses there can be moments of surprise when an emotion is expressed, be it briefly then gone again.
No, hvml, it isn't always easy but then nothing is with dementia. I'm so pleased that you feel less helpless. Try not to get too down when certain things don't seem to work, you just never know when they will and when not.
Here's hoping the walks in the fresh air to help your Dad to sleep better.
