I just joined here, but I have been a member of the Alzheimer's Association Message boards for a while now. There are so many great people on those boards (as i am sure there are here too) who have been so supportive and answered a lot of my very big questions. I am trying to find all the support I can get, and if you are like me you have to check this out. I know it may be wierd that my first post is like a banner ad for another message board, but I just want you all to know there is help out there.
So if you go to http://alzheimers.infopop.cc/eve you will reach that message board. I go to the Caregivers Forum, but there are other sections that many other members tend to hang out in.
Another great resource has been http://alz.org this is the Associations main webpage.
Hope you find it as helpful as I have.
