The dementia is progressing very fast in my husband. He is in a wheelchair now, his legs won't support him, he sleeps a lot during the day, sleeping at night most of the time, no bearing on his awake days, sometimes doesn't sleep those nights before. He is in a nursing home, meds he takes are Excelon pill and Namenda, plus Ativan and Buspar and Lasix for edema in feet and ankles. Bladder and bowels are totally incontinent now, totally dependent on others to dress him, clean him, he is confused about feeding himself, content for me to feed him. He doesn't talk, if he tries, the word doesn't make sense. He actually has no quality of life now. And hasn't for over a year when he was diagnosed with degenerative dementia. He takes his meds well now, and not combative as he was. I feel that is due to the dementia, not the meds.
There seems to be no rhyme or reason or logic for anything now.
I have also almost become addicted to audio books and enjoy them very much involved in the stories while in the car. 
Thank you for your response. I forgot to tell you that my husband is only 68, so at the age of 67, after the first CT scan, I was told the deterioration of his brain was far more advanced than it should be for someone his age. My husband was not in on that conversation. He never admitted anything was wrong, and only went to the Dr. for follow up to prove to everyone he was fine. Which, of course, proved that he wasn't. From May to July of '08. July I had to take him to the hospital emergency room, and from that time on, he has not been home, because of his violence and the security envirornment that he needed, first in assisted living and now nursing home.
The nursing home is an hour from where I live. I go every day. There have been days that I haven't gone, due to weather or on occasion when I didn't feel well, or very few, but a few times that I just couldn't face the day. His concept of time, however, is such that if I am not there, the next time that I am, he thinks is the day after the last time.
I do have support and encouragement from our 3 grown children. They come when they can, since they live in 3 different states, the closest 4 hours away. My church family is wonderful. But, I'm sure that by support, you mean a group for the disease. I am in contact with people that have gone through similar experience.
The care that my husband receives at the nursing home is just wonderful, that gives me a peace of mind, on the days that I'm not able to see him.
Isn't it strange that all the symptoms are pretty much alike, but no two people are exactly alike in how the disease affects them?
