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: Improving everyday memory in healthy aging and early AD
Date: [293]
Request ID: S2102
Aim 1: Test whether and how attention to event segmentation improves elders� memory for everyday activity at delays from minutes to weeks.
Aim 2: Test the hypothesis that effective event segmentation improves the resolution of elders� posterior/medial memory representations.
Aim 3: Test whether the mechanisms and consequences of segmentation improvement are maintained or impaired by early symptomatic Alzheimer�s disease.

Investigator: Catherine Roe and Ganesh Babulal
Project Title: Naturalistic driving as a functional neurobehavioral marker of preclinical and symptomatic Alzheimer disease (AD)
Date: [293]
Request ID: S2101
Aim 1: Use established cerebrospinal fluid (CSF) and imaging biomarkers to define preclinical AD and test the ability of the DRIVES to distinguish persons with and without preclinical AD among cognitively normal older adults, and assess the ability of the system to predict the future onset of dementia.
Aim 2: Test the ability of the DRIVES data to distinguish cognitively normal persons from those with dementia cross-sectionally, and to examine driving behavior over time for both groups.
Aim 3: Determine whether the DRIVES data, combined with cognitive, health, and functional data from older adults, can improve prediction of incident cognitive impairment and dementia.
Aim 4:
Investigator: Sarah Hartz (MPI Jessica Mozersky)

Project Title: Neuroinflammatory and Alzheimer’s Disease Imaging Biomarkers in Obesity
Date: [293]
Request ID: S1904
Aim 1: Aim 1: To determine the presence of neurodegeneration in MAOO compared to MNOO and control (normal BMI < 25) groups amongst cognitively normal participants in the Knight ADRC. We will define minimum criteria for MAOO of BMI 25 and HbA1c of 5.7, MNOO with BMI 25 and HbA1c < 5.7%
