LOAD Informed Consent
We sincerely appreciate your interest in our research. This study is funded by the National Institute on Aging (NIA) to help researchers find genes that increase the risk for Alzheimer’s disease (AD). This webpage will provide you with the information and instructions you will need to determine if this study is right for you and your family. If If you have any questions at any time, feel free to contact us at email@example.com or toll-free at 1-800-526-2839.
What is the Purpose of This Study?
Alzheimer's disease is the most common neurodegenerative disorder of the elderly affecting an estimated five million Americans. Genetic factors contribute to the risk for disease with heritability estimates ranging from 57% to 79%. More than a decade ago, the ε4 variant of APOE was identified and remains the most consistently replicated genetic variant influencing the risk of late onset Alzheimer's disease. A segregation analysis suggests there may be four additional genes influencing the age-at-onset of Alzheimer's disease. In 2007 there were 968 association studies in 398 candidate genes reported, but none replicated consistently. There are many reasons for the lack of consistency, but one important reason for the lack of progress is the insufficient number of well characterized families and patients available to the entire scientific community.
Its goal is to identify and recruit families with two or more siblings with the late-onset form of Alzheimer's disease and a cohort of unrelated, non-demented controls similar in age and ethnic background, and to make the samples, the clinical and genotyping data and preliminary analyses available to qualified investigators world-wide. This genotyping represents the largest collection of families ever assembled with Alzheimer's disease combining the NIA-LOAD Genetics Initiative Multiplex Family Study, the National Centralized Repository for Alzheimer's Disease and Related Dementias (NCRAD) with additional controls from the University of Kentucky. These genotyping results will serve as a focal point for future research that will identify all of the remaining genetic variants in Alzheimer's disease.
Therefore, LOAD is looking for families with living siblings with Alzheimer’s disease. These family members will need to provide a blood sample and medical records.
In order to determine if you are eligible for the NIA-LOAD study, you will need to complete a few simple steps.
