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: Everyday Memory in Aging and Alzheimer’s Disease
Date: December 21, 2021 at 5:28 pm
Request ID: S1702
Aim 1: Test the hypothesis that age and biomarkers for AD neuropathology are associated with impairments in the ability to notice and remember changes.
Aim 2: Use an experimental approach to test one potential mechanism: reduced fidelity of medial temporal activity patterns leading to impaired detection of discrepancy.
Aim 3: Attempt to remediate age- and AD-related memory deficits by enhancing elders� encoding of new events in relation to related previous events with a cuing procedure.
Aim 4:
Investigator: Jason Hassenstab

Request ID: S1606
Aim 1: To discover, optimize, standardize, and validate clinical trial measures and biomarkers used in AD research
Aim 2: To capture rates of decline on cognitive, global and functional tests and the rate of conversion to MCI or dementia due to AD.
Aim 3: Determine the longitudinal extent and rate of amyloid and tau deposition in PET Scans and longitudinal change of cerebral tau correlated and compared with other changes in cognition and biomarkers
Aim 4: Determine which clinical, cognitive and biomarker and imaging capture detection of treatment effects and measure cognitive decline for all groups with a focus on biomarkers and Tau.
