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: Jennifer Molano

Project Title: The Effect of Alzheimer’s Disease Biomarkers and Sleep on Cognitive Performance

Date: [153]

Request ID: D1402

Aim 1: CSF levels of Aβ42, tau, ptau181, tau/Aβ42, and ptau181/Aβ42 indicating AD pathology will be associated with worse psychometric performance on tests of memory and/or executive functioning among cognitively normal adults, both cross-sectionally and longitudinally.

Aim 2: Sleep efficiency will be an effect modifier on psychometric scores, with worse sleep efficiency correlating with worse psychometric performance on tests of memory and/or executive functioning cross-sectionally and longitudinally, after accounting for any effect of CSF AD biomarkers. termine if
