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: An Investigation of the Relationships Between Brain Structure and Attentional Control
Date: December 21, 2021 at 5:18 pm
Request ID: D1516
Aim 1: To identify brain regions that support successful attentional control processes by examining the relationships between brain structure and performance on attentional control tasks.
Aim 2: To investigate the brain structural changes that lead to attentional control impairments in Alzheimer�s Disease.
Aim 3: To examine whether brain structure at least partially mediates the relationships between AD risk and attentional control.

Date: December 21, 2021 at 5:18 pm
Request ID: D1511
Aim 1: Examine results from a psychometric battery of cognitive tests for patients with no evidience of clinical dementia
