Frequently Asked Questions about NCRAD


What Is the National Cell Repository for Alzheimer’s Disease?
The National Cell Repository for Alzheimer's Disease (NCRAD) is a resource facility funded by the National Institute on Aging. The purpose of the Repository is to provide important and critical resources to assist researchers in identifying the genetic factors (genes) contributing to Alzheimer’s disease and other types of dementia. To perform these important studies, scientists require genetic material (DNA) from individuals and families having multiple members diagnosed with Alzheimer’s disease or other types of dementia. Learn more about the genetics of Alzheimer's Disease.

Where Are We Located?
The National Cell Repository for Alzheimer's Disease is housed at Indiana University Medical Center in Indianapolis, Indiana. Even though we are located in Indiana, we work with families nationwide. It is not necessary for study participants to come to Indiana.

Who Can Participate?
We are looking for families with two or more blood related individuals who may be affected with memory loss or Alzheimer’s Disease (AD) and who are still living.

How Might Family Members Be Asked To Participate?

  1. Provide Family History Information. As part of a family’s participation in this study, you may be asked to provide family history information. You also may be contacted periodically for additional or updated family information.
  2. Provide a Blood Sample. The blood samples that we request are not used to test for a diagnosis of AD. These samples are used to obtain the genetic material, called DNA, that is used for research.
  3. Provide Documentation of Clinical History. Family members may be asked to sign medical release so that we can obtain documentation of serious memory loss or AD in the family. Some members may be asked to undergo physical and/or neurological examinations. These examinations may be performed in a clinical research center or an Alzheimer’s disease researcher may come to see the family member.
  4. Plan an Autopsy for Yourself or a Loved One. One other way that we can learn more about AD is through the careful examination of brain tissue of family members who have been diagnosed with AD. We can work with families to arrange an autopsy plan and we will help cover the costs associated with the autopsy.

Why Is This Project Important?
In order to identify the genes important in predicting who is likely to develop Alzheimer’s disease, researchers must perform genetic studies using DNA from individuals who have and have not developed Alzheimer’s disease. It can be extremely costly and time consuming to identify individuals and families with multiple members diagnosed with Alzheimer’s disease. To help researchers more rapidly unravel the mystery of Alzheimer’s disease, the NIA is working with 29 Alzheimer’s Disease Research Centers to identify 1,000 families with 2 or more living brothers or sisters diagnosed with Alzheimer’s disease.

Is Participation Ever Manditory?
Participation in the National Institute on Aging Alzheimer’s Disease Family Studies are totally voluntary. All individuals participating in the National Institute on Aging genetic studies must sign an Informed Consent form that gives permission for each individual to participate in this project. Family members are free to decline or discontinue participation at any time. There should be no cost to take part in the study. All information you provide will be kept confidential.
