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: Pathways of Stress and Support: How Social Determinants Influence Dementia Outcomes in Black Americans
Date: June 4, 2026 at 9:50 pm
Request ID: D2637
Aim 1: To identify SDOH (i.e., access to transportation, financial security, healthcare experiences, & discrimination) and the association with dementia severity.
Aim 2: Test whether social connectedness (i.e., lower reports of social isolation, activity, & community safety) moderates the association between SDOH (i.e., access to transportation, financial security, healthcare experiences, & discrimination) and dementia severity.

Project Title: Development and validation of the Alzheimer Dynamic Instability Score (ADIS): a biological markers and risk factors approach to detect critical transitions in Alzheimer’s diseases
Date: June 3, 2026 at 1:30 pm
Request ID:
Aim 1: To develop the Alzheimer Dynamic Instability Score (ADIS) as a composite measure of resilience loss and dynamic instability. We will construct ADIS by integrating longitudinal measures of variability, deterioration velocity, acceleration of decline, cross-domain coupling, and biomarker burden
Aim 2: We will evaluate whether ADIS progressively increases from cognitively normal (CN) individuals to mild cognitive impairment (MCI) and Alzheimer’s disease dementia (AD), supporting its validity as a marker of disease-related instability.
Aim 3: Using longitudinal data, we will test whether elevated ADIS values predict conversion from MCI to AD dementia and accelerated cognitive decline over time.
Aim 4: We will compare the predictive performance of ADIS against established biomarkers (pTau217, NfL, GFAP, hippocampal volume, MMSE, CDR-SB) and determine whether incorporation of ADIS into machine-learning models improves risk stratification and early detection of tipping-point–like transitions.
