Ages 18 and older · All sexes · Healthy volunteers welcome
Full eligibility criteria
Inclusion Criteria: * Two living family members diagnosed with AD or other dementia with any age of onset * Biological samples available * Fresh blood, or * Immortalized lymphoblastic cell lines, or * 3-5 grams of frozen cerebral cortex; fixed samples are not accepted Please note: this study does not include genetic counseling; because no personal identifying information such as name or date of birth is attached to samples, results of individual tests are not available to participants or family members.

About the study
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.
