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:Subjective memory complaints in prodromal familial Alzheimer’s disease and its association with amyloid burden in the brain

Date of Request:1/21/2013

Status:A

ID:DIAN-D1301




Aim 1:Find out whether presymptomatic FAD mutation carriers (CDR=0) with subjective memory complaints show a higher percentage and degree of pathological (positive) amyloid load in the brain (precuneus) measured by PIB-PET than those without subjective memory complaints.




Aim 2:Find out the time relation between subjective memory complaints and estimated years from symptom onset respectively development of clear deficits in cognitive tests (e.g., pathological logical memory test), MCI and dementia.




Aim 3:Find out the time relation between subjective memory complaints and development of pathological (positive) amyloid load in the brain (precuneus) measured by PIB-PET.
