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: Gregory Van Stavern, MD
Project Title: Ocular biomarkers in early and pre-clinical AD
Date: July 28, 2015
Request ID: S1508
Aim 1: Assess differences in OCT metrics between normals, pre-clinical AD and early AD subjects
Aim 2: Assess changes in retinal and optic nerve blood flow in pre-clinical and early AD
Aim 3: Measure subretinal protein degradation products using OCT and compare with brain ABeta

Investigator: Palmer, Janice L.
Project Title: A pilot study of measurement of temperature and sleep in older adults with dementia
Date: June 5, 2015
Request ID: S1507
Aim 1: To evaluate the tolerability, feasibility and fidelity of a measurement protocol of temperature at wrist (using iButton)
Aim 2: To evaluate sleep parameters including time to onset of sleep, percent time awake and asleep during the night, number of awakenings per night, length of awakenings at night using wrist actigraphy (MotionWatch)
Aim 3: To evaluate the recruitment and retention of 10 adults age 65 and above (2 with no dementia [CDR=0] and 8 with mild to severe dementia [CDR=1 or above]) in a study of the measurement of temperature and sleep.
Aim 4:

Investigator: Randall John Bateman, MD
Project Title: CNS Tau Kinetics in Healthy Aging and Alzheimer�s Disease
Date: April 28, 2015
Request ID: S1506
Aim 1: To measure physiological tau kinetics with the tau SILK method in the CSF of normal human participants.
Aim 2: To measure pathological tau kinetics with the tau SILK method in AD patients.
Aim 3: Differences between AD and controls will be assessed with kinetic models. We will address the question of whether tau kinetics in the CNS is altered in AD with either over-production or under-clearance.
Aim 4:

Investigator: Sarah Hartz
Project Title: Comparison of methods for return of results in Alzheimer’s studies
Date: April 24, 2015
Request ID: S1505
Aim 1: Evaluate whether returning imaging and genetic results to cognitively normal subjects by the telephone is inferior to returning results in person
Aim 2: Determine the cost to the study of returning results to cognitively normal subjects both in person and by telephone
Aim 3:
Aim 4:

Investigator: Tom Morris
Project Title: Remembering with a Partner in Old Age: Compensatory or Protective Effects of Collaboration in Cognitive Dysfunction
Date: April 23, 2015
Request ID: S1504
Aim 1: To determine whether remembering with a long term partner can compensate for memory dysfunction
Aim 2: To examine whether impaired individuals remember better in collaboration with their partner vs. remembering alone
Aim 3: To investigate the specific processes and cognitive support strategies that predict better collaborative recall
Aim 4:

Investigator: Angela Curl

Aim 1: Assess the diagnostic accuracy of five spatial navigation-related tasks
Aim 2: Assess the reliability of five spatial navigation-related tasks
Aim 3: Assess the validity of five spatial navigation-related tasks
Aim 4:

Investigator: John Morris
Project Title: Antecedent Biomarkers for AD; The Adult Children Study
Date: February 9, 2015
