Late Onset Alzheimer's Disease (LOAD)
September 16, 2022 updated by: Columbia University
The goal of this study is to is to focus on the genetic influences on Alzheimer's Disease (AD) risk.
The investigators are looking for families and/or individuals (affected or unaffected) of any ethic background (African American, Caucasian, and Hispanics) with a family history of AD and willing to participate.

Detailed Description
The purpose of this study is to focus on the genetic influences on Alzheimer's disease (AD) risk.
Specifically, the investigators hypothesize that one or more genes, other than the previously identified susceptibility gene apolipoprotein-E (APOE), or the 3 genes associated with early-onset familial AD, presenilin-1 (PS-1), presenilin-2 (PS-2) or B-amyloid precursor protein (APP), increase the risk of AD in families with multiple individuals affected with AD.
The investigators propose to test this hypothesis by performing genetic linkage analysis in order to detect the chromosomal location of genes that may increase the risk of Alzheimer's disease.
In addition, the investigators will study genes known to increase the risk of Alzheimer's disease and other related disorders such as early onset AD, Pick disease, corticobasal degeneration, progressive supranuclear palsy, and familial frontotemporal dementia with parkinsonism and Lewy Body Dementia.

Participation Criteria
Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Sampling Method
Probability Sample
Study Population
The investigators intend to recruit individuals from: 1) community-based studies; 2) the Alzheimer's Disease Research Center Memory Disorders Center; 3) the private offices of the study neurologists; 4) public recruitment; 5) referrals from the Alzheimer's Association; 6) referrals from the NCRAD; 7)previously unidentified members of existing families not previously recruited.
The investigators will also use advertisements such as radio, television and newspapers.
Description
Inclusion Criteria:
- Established diagnosis of definite or probable AD or have a diagnosis of a related neurodegenerative disorder such as Frontotemporal Dementia (FTD) or Lewy Body Dementia (LBD) (will also recruit sporadic FTD and LBD) cases.
- a living sibling with probable or possible AD;
- a third living relative affected with AD (onset age 50 or older) or unaffected (60 or older);
- participants in the proband's generation with an identified companion serving as an informant;
- participants who have capacity to consent or participants lacking capacity to consent with a surrogate/proxy in place to provide consent.
Exclusion Criteria:
- failure to identify an appropriate informant;
- uncertainty of the clinical diagnosis of Alzheimer's disease or other related disorder;
- discovery of additional diagnosis that could account for the clinical manifestations;
- unwillingness to participate;
- failure to identify a living sibling with AD or other related disorder (except in the cases of sporadic FTD and sporadic LBD);
- participants lacking the capacity to consent who do not have a surrogate or proxy or next of kin to provide consent.

Plan to Share Individual Participant Data (IPD)?
YES
IPD Plan Description
Data is stored in a secured database at Columbia University and de-identified data will be sent to the National Cell Repository for Alzheimer's disease.
DNA will be stored at the National Cell Repository for Alzheimer's disease (NCRAD) at Indiana University.
In addition to the blood sample, year of birth, family history of dementia, and diagnosis will be sent to NCRAD.
DNA and associated clinical and demographic data will be made available to qualified and approved researchers studying the genetics of AD, aging, and related disorders.
If the participant agrees, his/her de-identified samples and data will be made available to investigators studying the genetics of any human disease.
Identity of participants will not be shared with NCRAD or with any investigators.
IPD Sharing Time Frame
The data is currently available
IPD Sharing Access Criteria
When requesting samples to NCRAD the "Master Agreement for Transfer of Materials to NCRAD" and related Appendix A must be completed prior to the transfer of any samples.
The Master Material Transfer Agreement (MTA) agreement is between the Institutions and is not Investigator specific.
Therefore, if you think your Institution may already have a Master MTA in place with NCRAD.
