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: Ganesh Babulal
Project Title: Daily Cognitive Performance and Variability in Predicting Naturalistic Driving Behavior
Date: August 23, 2022
Request ID: D2217
Aim 1: To determine if mean level differences in cognition or variability in daily cognitive performance, as measured with the Ambulatory Research in Cognition (ARC) study, mediate differences in driving behavior associated with amyloid pathology.
Aim 2: Examine whether daily cognitive performance on ARC correlates with driving behavior on the same day
Aim 3: Evaluate whether changes in driving behavior are associated with differences in cognition (mean performance and variability) measured with ARC
Aim 4:

Project Title: Vascular Contributions to Dementia and Genetic Risk Factors for Alzheimer disease
Date: August 23, 2022
Request ID: S1701
Aim 1: Evaluate longitudinally biomarkers of BBB breakdown (i.e., sPDGFRβ, CypA-MMP9 pathway, Qalb, fibrinogen) by serial CSF analysis in relation to serial Aβ and tau AD biomarker (CSF, PET) changes and cognitive decline.
Aim 2: Evaluate longitudinally BBB permeability by serial DCE-MRI measurements in relation to CSF biomarkers of BBB breakdown, Aβ and tau AD biomarker (CSF, PET) changes and cognitive decline.
Aim 3: Examine longitudinally BBB breakdown by serial DCE-MRI measurements in relation to serial CBF pCASL-MRI measurements, Aβ and tau AD biomarker (CSF, PET) changes and cognitive decline.
Aim 4: Evaluate regional BBB integrity (DCE-MRI) in relation to change in structural and functional connectivity and cognitive decline over time.
