Will Ancestral DNA Research Reveal Alzheimer’s?

As I read a post at Eye on DNA, Genetic Genealogy Mildly Hot, and how DNA is being used to trace ancestors and find distant relatives, I wondered if families would discover connections with Alzheimer’s.  A number of questions flitted through my mind:

*Would one find ancestors with dementia or Alzheimer’s in the family history?

*Will they find distant cousins who suffer from Alzheimer’s or have family members who do?

*If your family member (parent/spouse/aunt/uncle/grandparent/sibling) has Alzheimer’s, will you find a history of this disease as you use DNA to find ancestors?

*Will we find there’s a genetic or hereditary connection to Alzheimer’s?

Just some points to ponder.
