Hi Debbie...

Your question got me to thinking so I went on a little search...

I found a couple of sites that talk about genetic testing and diagnosis for Alzheimer's.

Alzheimer's Society -- Canada

Medline Plus
http://www.nlm.nih.gov/medlineplus/e...%20and%20tests


Alzheimer's Association -- United States

Hope this helps...

Abbie
