Hi, sorry for the time wait, I generally spend most time on the UC forum. To the best of my knowledge, the disease can progress from the first noticable symptoms of forgeting words, etc. to not being able to speak in about 5-8 yrs. You can find out more by looking up Alzheimers on line. My Grandma went from normal to no speech and not being able to feed herself, incontenent etc. in about 8 yrs. She passed away a yr later at 88.
In my work place, in the passed 6 yrs, I've known one lady who could not find her room, but could talk, remember her kids etc. and was and is a wonderful happy laughing lady. Now she still smiles and laughs, which is rare for these people. She does not know her kids, can't feed herself, is incontenant and is blind. She cannot carry a conversation, but says words. I still love to see her, but my heart goes out to her daughters who visit. It's a hard thing to see your own mom like this.
Do not let any stares or quiet comments stop you from taking your Mom out in public. Trips out are wonderful, and who cares what others may think!!! We don't have much of that kind of discrimination here in Canada. Not that I've noticed. Where do you live? There are national American and Canadian Alzhiemer's Disease Centers that may be of help to you.
Best of luck Forget-me-not....Sassy
