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: Comparative Deep Learning Analysis of Familial and Sporadic Alzheimer’s Disease
Date: August 15, 2025 at 2:37 pm
Request ID: D2535
Aim 1: Develop a foundation model (merging with the other data generated by the Crary lab).
Aim 2: Use supervised convolutional neural networks (CNNs) to classify images based on disease group and genotype, using regions of interest enriched for known pathological features (e.g., amyloid plaques, neurofibrillary tangles).
Aim 3: Apply multiple instance learning (e.g., CLAM) to detect latent features that distinguish familial and sporadic AD without relying on annotations (unsupervised), and interpret attention maps to identify novel morphologic signals.

Request ID:
Aim 1: Quantify the combined and interactive effect of APOE genotype, AD-PRS, and CRS on age of symptom onset in ADAD mutation carriers. We hypothesize that higher cumulative genetic and clinical risk burden will predict earlier symptom onset, beyond the effects of monogenic mutations alone.
