My grandfather suffered from dementia also. When my grand mother was around he seemed better but when she was gone he would get really bad, not even remembering his fondest memories, he would also get worse at night. My grandma passed away on the 26th of this month and I was moving my grandpa in my house and 2 days later he had a massive stroke, the worst the hospital had seen,major bleeding in the 3 chambers of the brain. He died from it on the 30th. It's crazy because he was seeing my grandma right before the stroke.He was also having moments of clarity where he actually remembered she died. I guess love knows no boundaries and as my 11 year old son put it,"now he can remember and he's with mama" I'm happy that they have this service to offer to families, to help them understand what people suffering with dementia go though. Kudos to you for posting this!Peace.
