I just want to share with you a story:
There is a gentleman I know .. a sweet, gentle loving man. He's in a Dementia specific wing in a nursing home. He wouldn't hurt a fly, but he often seeks out a carer and claims he's lost.
Well, tonight he sought me out. I explained to him very carefully that his wife knows he's staying in the nursing home, and I explained to him that he's 90 years old (shock .. but I'm only 85!! No honey, your 90... OMG .. where did 5 years go?) and that he's got SOOOO many memories his brain has run out of space, so he can't remember the more recent stuff.
It helped CALM him. Then he said "you know, I think my Dad went like that too" and I said "Then you have both lived long and full-filling lives" and he chuckled. He was concerned about his wife, but I let him know she's safe and she knows where he is and wants him to stay there. I explained to him that he was taking his med's wrong, going for walks and getting lost and how scary it was for everybody and how safe he is now. He was really happy with that and went and sat down in a chair. No sooner did he sit down, that he bounced back up and came straight back to me ... with the EXACT. . . word for word questions .. "Why am I here? and Where am I?" .. amazing .. absolutely amazing ... so we went through the conversation AGAIN ... (bit faster this time LOL) .... .and off he went to bed. Within 20 minutes he was back saying "I've had a dream and it couldn't possibly be true" and I asked what and he said "something about Short Term Memory loss?"
Something sunk in LOL.
he is one of the ODD ones suffering this disease that you CAN do reality therapy with. There is another gentleman I know, that you can't, under any circumstances even GO in that direction.
THIS is the learning curve .. learning what you can and can't say .. THAT'S the hard bit ....
Glad I didn't upset you
