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.

Date of Request:3/16/2015

ID:DIAN-D1503

Aim 1:To compare the patterns of neuromorphometric changes throughout the predementia and dementia stages of dominantly inherited AD (diAD) and sporadic AD (sAD)

Title:to be decided

Date of Request:3/27/2015

ID:DIAN-D1504

Aim 1:exploration of data using the structural equation modeling

Title:Using DIAN to motivate statistical methods in aging and dementia research

Date of Request:6/11/2015
