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:Psychosis in dominantly inherited Alzheimer’s disease

Date of Request:07/08/2019




Aim 1:To determine the frequency of psychosis in DIAN family members, and to explore associations between psychosis and different genotypes




Aim 2:To examine the relationship between neuropsychiatric symptoms and estimated years to and from cognitive symptom onse




Aim 3:3. To determine if there is a relationship, and any potential interaction, between psychotic symptoms and previously reported risk/modifier alleles (5HT2A receptor polymorphism, SNPs in RP11-541P9.3, ApoE status) and environmental risk factors (e.g. history of substance abuse)




Aim 44. To explore associations between neuropsychiatric symptoms and fluid, imaging and cognitive biomarkers of disease

Title:Longitudinal tau PET in dominantly inherited Alzheimer’s disease

Date of Request:07/04/2019




Aim 1:a) to understand the role tau PET imaging can play as a marker of early Alzheimer’s disease for clinical diagnostic purposes and also as a biomarker in trials of individuals with autosomal dominantly inherited forms of Alzheimer’s disease (ADAD)




Aim 2:b) to optimize static and dynamic methods of tau PET analysis in order to achieve better longitudinal consistency and reduce sources of within-subject variability




Aim 3:c) to improve understanding of when and where tau deposition occurs, and how these relationships change over time;




Aim 4d) to determine the relationship between changes in tau deposition and changes related to neurodegeneration and cognitive decline; and
