Search DIAN Data Resource Requests

In order to avoid the situation where two investigators study the same research question, please search our database to determine if your topic has already been studied. If you find that your topic or a related topic has already been submitted, you may wish to contact the investigator to inquire about his/her findings to determine how you might proceed. You may wish to collaborate or modify your request to avoid overlap. The results below reflect requests made since online requests have been accepted. As such, not all fields will have data as certain information, such as aims, were not collected until recently. If an entry has been assigned an ID # (e.g. DIAN-D1004), the full request has been submitted and is either approved, disapproved or in process.

Title:Preclinical familial and late-onset Alzheimer’s disease brain changes

Date of Request:10/17/2012

Status:IA

ID:DIAN-D1209




Aim 1:Determine which sMRI, rs-fMRI, and DTI brain measures together best distinguish FAD mutation non-carriers from FAD mutation carriers within 10 years from their estimated age of disease onset.




Aim 2:Identify which sMRI, rs-fMRI, and DTI brain measures change faster over three years in FAD mutation carriers within 10 years from their estimated age of disease onset compared with age-matched FAD mutation non-carriers.




Aim 3:Discover whether Aim 1 effects are seen in higher AD risk ADNI adults (based on CSF Aβ42 levels and memory scores) versus lower risk ADNI adults (based on CSF Aβ42 levels), and whether the measures predict cognitive decline over 3 years.
