Mom and dad are 91 and married 71 yrs. Both have progressive and different forms of dementia. They lived rather independently with my sisters and my help until this past year. Dad having health issues and was just discharged from hospital to rehab. He's not doing well. They tell us he's in failure to thrive and and now has pneumonia. I don't think he has a good prognosis. Mom doesn't understand. She can't remember where he is and why. Every minute we have to explain to her. We see her failing now too. Have no idea how we should tell her or if we should. Do we continue to let her believe he's just in the hospital for ever even if he passes?? If he passes, she will probably lose the will to live and we'll lose her too. Thoughts???
