Search Existing Data Requests

The Knight ADRC has supported many investigators at Washington University and at other institutions over the years. We wish to avoid the situation where two investigators study the same research question to avoid duplication of effort and potential conflict. To determine if your topic has already been studied with our resources, please search our database. If you find that your topic or a related topic has been submitted, you may wish to contact the investigator to inquire about their 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 number (e.g. T1004), the full request has been submitted and is either approved, disapproved or in process. If an entry has no ID number, then it represents a submission that has not yet been reviewed. Search terms are applied across an entire requests application including variables not displayed below. A more specific, detailed search may yield better results depending upon your needs.

Investigator: Karin Meeker

Project Title: Alzheimer disease heterogeneity profiles in ethno-racial minorities

Date: [153]

Request ID: D2204

Aim 1: Determine AD brain volume heterogeneity profiles of neuroimaging markers (i.e., magnetic resonance imaging [MRI], resting-state functional connectivity [RS-FC]), cognition, and AD biomarkers (i.e., plasma amyloid and tau).

Aim 2: Assess group differences in heterogeneity profiles between Blacks and Non-Hispanic Whites.

Aim 3: Determine whether social determinants of health (SDOH; e.g., ADI) mediate group differences in heterogeneity profiles.

Aim 4:


Investigator: Brian Gordon

Project Title: Comparing biomarkers between Down Syndrome, Autosomal Dominant, and Late onset Alzheimer Disease

Date: [153]

Request ID: D2205

Aim 1: How do measures of tau pathology measured using PET compare among DS, ADAD, and LOAD?

Aim 2: Does the spread of tau pathology over time differ between cohorts?

Aim 3: How do the degree and spatial patterns of neurodegeneration compare between DS, ADAD, and LOAD?

Aim 4: How do biofluid profiles compare between DS, ADAD, and LOAD? We will expand upon our prior publication

Project Title: Predictors and Outcomes of Clinical Dementia Rating Reversion.

Date: [153]

Request ID: D2208

Aim 1: To understand the clinical significance of individuals who revert between cognitive normality and meeting the clinical diagnostic criteria for dementia on the Clinical Dementia Rating (CDR) score, coined “reversion.”

Aim 2: To examine if reversion is related to cognition, genetics, fluid biomarkers, and neuroimaging markers.

Aim 3: To examine if instances of reversion are a predictor of future stable CDR >0 and a clinical diagnosis of Alzheimer’s Disease (AD).

Aim 4:


Investigator: Janardan P. Pandey
