Perhaps the cruelest aspect of Alzheimer's is that it robs families of their loved ones before they are truly gone. Loss of memories and physical abilities frustrates patients and pains family. Every health professional who works with Alzheimer's looks forward to the day when patients can be told there is a cure.
I had one last thing to do in London before going home to my parents in Hampshire, and that one thing is to visit my mother-in-law. My MiL is in the grips of Alzheimer's disease. She does not recognise me. She lives in a world where her parents are still very much alive, where she still goes to work. I no longer exist in her world.
