There's a new online Alzheimer's disease support group at www.mdjunction.com/alzheimers-disease. It looks like a very good site with a lot of help. I'll be posting the link on the sidebar, as well.
Also, www.aplaceformom.com is packed with experts, articles and advice on finding care centers in your area. There are people from all over the country to help. Just choose your location. They have a community of caregivers blogging, as well.
Do visit both of these fine sites and see if they have what you are looking for.
