All of the people who posted here are intelligent and their only concern is for the people they are caring for. To get a diagnosis, you'll have to go through many doctors I'm afraid. I would start with a geriatric doctor first, and make sure you "click" with them. Alz patients lose weight to begin with when the onset of their symptoms worsen; it's a hard time for them and there is no medical reason behind it. They're just scared. Period. Who would want to eat when this is happening???
Yes, they become our children. It's amazing how that works; my mother forgot my name and face, but never failed to recognize my voice. Recognize the connections you have with the person you're caring for, as this could mean the difference between a good day or a bad one, and someday it might mean the difference between life and death. Yes, I have been there.
Of course, the diagnosis is for us, and not them, as there is nothing you can do with it. And yes, still there is no sure way except post mortem. Check caregiving websites and childproof your home, as shuffling is also a huge part of the disease. Mumbling is key, as they will have bouts of trouble communicating. They isolate themselves, and do not like change in any manner. Taking them outside of their comfort zone is a challenge to not take lightly. Keep in mind that the connection from the brain to the body is broken or static, and so every day things confuse them. The best way to handle it is to think of them like a child, but give them as much control over their lives as possible. I think we all agree that their best interest is our only concern. The first thing you can do is help them live in dignity and and the last is to die with loved ones by their side. Sad but true.
Driver's Licenses: Boy, this is a tough one, as it's taking their independence away and it really hurts their pride. The only way to have it pulled is from a doctors note stating they are unable or unfit. If you cannot communicate with the doctor, find another one. Letting a loved one out on the road endangers everyone (duh). I did this with my father; it was really tough, but we didn't have to deal with an accident or someone dying because of it - thankfully. I did follow him one day and confirmed my worst nightmares; he once was the best driver I had ever known. On the other side, ensure they have access to cabs or buses (with supervision when the time comes), so that they still have some control. Your connection with your doctor is extremely important; many have a god complex, but a good one will work FOR YOU and not against. You have enough problems as it is right?
And yes, this website is great. No one judges and there are many who have walked in your shoes. We commend you and have lots of advice to get you through the dark days ahead. Someday it will come to an end, and it will be a shock for you, the caregiver, to have your life changed overnight. No one can prepare you for it, but when it's over and done, you'll remember those moments that made it all worthwhile. I call it the magic moments. They kept me going...
It might help to remember that when you fell you can't go on any longer, imagine us standing by your side giving our support and cheering you on. You are the unsung hero's, as a hero doesn't think of themselves first and they do it because it's the right thing to do.
