Science Buddies: "Ask an Expert"

Hello!
My classmates and I have been assigned to create a science fair project for our local science fair. I am very interested in Alzheimer's Disease. I would like to know if Alzheimer's Disease can be detected before somebody gets it? Can some sort of home kits be created to test whether a person has Alzheimer's Disease?
I would appreciate any responses or suggestions. Thank you for taking your time and reading my post.
