Is there a support group dealing with elderly for caregivers?

Tad, yes there are. I don't know what I would have done without my friends here for nearly three years now. And it took me a year to find this site.

Another option is the Alzheimer's Association in your area you can find a listing of meetings here:

Why yes, there is. As a matter of fact you are in it - it's right here.

Also check with your public library, local churches, and Community Ed.

The rehab where my mother was and the MC where my father was both had support groups, and you did not have to have a family member there to join. Call your local homes and see if they have anything! Also the area ageing agencys , ect.
