The purpose of the Alzheimer's Disease Genetics Study is to identify the genes that are responsible for causing Alzheimer's Disease (AD). One of the ways in which the risk factor genes for late onset AD can be investigated is by identifying and collecting genetic material from families with multiple members diagnosed with AD or dementia.

Population

Families with two or more members with Alzheimer's disease or dementia

Brief Title

Alzheimer's Disease Genetics Study

Official Title

National Centralized Repository for Alzheimer's Disease and Related Dementias (NCRAD)

Brief Summary

The purpose of the Alzheimer's Disease Genetics Study is to identify the genes that are <br /> responsible for causing Alzheimer's Disease (AD). One of the ways in which the risk factor <br /> genes for late onset AD can be investigated is by identifying and collecting genetic material <br /> from families with multiple members diagnosed with AD or dementia.

Detailed Description

The purpose of the Alzheimer's Disease Genetics Study is to help identify the genes that may
be responsible for causing Alzheimer's Disease (AD) by collecting genetic material from
families with multiple members diagnosed with AD. Qualifying families will have two living
blood-related individuals who have been diagnosed with or are showing symptoms of AD or
dementia. Local study sites are located all over the United States, and arrangements may be
made for eligible families who do not live near a participating site. The biological samples
and data from these families will be made available to qualified researchers, who must sign a
Materials Transfer Agreement (MTA) in order to protect the privacy rights of study
participants before receiving samples and data.

Outcome Measures

Outcome measures are the tests that investigators perform to prove whether or not a treatment being tested in a clinical trial is having any effect.
