Alzheimer's Disease Genetics Study
This study collects blood or tissue samples from families with several members who have Alzheimer's or another dementia. Researchers want to find genes that influence late-onset Alzheimer's. No drug or treatment is being given. It is a genetics collection effort, so no phase applies. Details are limited so far.
