My father has ALS. He's72, diagnosed Jan, 2013. this week went to a nursing home and starting hospice. What has made it more challenging is my mother, 77, is heading to moderate/severe Alzheimer stage. They've been married 53 years, lived together until mid-July. Mother is now at memory care facility. She doesn't understand he has fatal disease and isn't going to improve. She has sympathy for him for short time then gets upset with him for "bad adttidude". It breaks my heart to have to "split" them up. How do we handle the question around her visiting my father and seeing the changes, versus holding the truth of the situation from her in regards to her husband? I am at a loss. My Father is very depressed and he can't seem to make decision himself about to see her or not. I'm not looking for the perfect answer, but wondering if anyone with familiarity with BOTH of these diseases has any words that just might help with these decisions. Maybe it just doesn't matter either way..
