My 93 year old grandparents have been married for 72 years. A couple of years ago my grandmothers health started to decline and she has moderate dementia. My grandfather had been in excellent health. my grandfather was killed in a car accident last month. My grandma's whole world revolved around him. She has started saying that she thinks Grandpa left her - like packed up his stuff and abandoned her - possibly for another woman. Normally when grandma slips into her "alternate realities", we just meet her where she is and let it go. But this delusion is hurting her - breaking her heart. We have tried gently reminding her that he was killed - and she'll just say "I just can't realize that." does anyone have any suggestions how we should approach this issue when she brings it up?
