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.

Project Title: Longitudinal Changes in Medial Temporal Lobe Functional Connectivity and Localised Tau Burden Among Older Adults
Date: December 18, 2024 at 10:47 am
Request ID: D2449
Aim 1: To explore whether longitudinal static and dynamic functional connectivity changes occur within sub-regions of the medial temporal lobe.
Aim 2: To measure whether these changes are associated with localised medial temporal lobe tau burden.
Aim 3: To determine whether medial temporal lobe functional connectivity and/or medial temporal lobe tau burden is associated with cognitive performance, and whether these relationships are modulated by cortical amyloid status and/or cognitive status.
Aim 4: (Supplementary) To explore participants’ Braak staging profiles, as to determine whether some participants do not adhere to the typical Braak staging spatial spread patterns of tau.
