He's 87 and actually in good health physically. He works out 3 times a week and lifts weights. He has been blind for most of his life, but he went to school, worked etc. He's done everything but drive.
By family reports, he was always a hateful child even before he lost his sight.
As an adult, a father and husband, we saw a lot of that hate and anger but he would stop at a point. In the past year though he has become progressively almost not even human. He seems unaware of anyone else's feelings or needs.
He and my mom fight 24/7 and he grabs and shakes her.
I talked to his doctor who did a basic cognitive exam and he said everything is
fine. I've offered to find my dad someone to drive him around so he'll be more free. I've offered to take him on two trips to see his old friends. I've tried getting my mom to leave (she hates him but feels that leaving now is too
big a change)
I am at my wits end of how to make this situation better. I'm an only child and there is no other family.
