Neurocognitive Disorders clinical trials at UC Health
3 research studies open to eligible people
open to eligible people ages 65-75
Postoperative neurocognitive disorders (PND), which include postoperative delirium and both acute and longlasting neurocognitive deficits, are a significant public health problem, leading to a cascade of deleterious complications. Older adults are particularly at-risk of developing PND both in the short and long term. Although age is consistently reported as an important risk factor, the exact pathophysiology of PND remains poorly understood, but may include postsurgery-compromised blood brain barrier (BBB) function. This project proposes that perioperative BBB dysfunction is associated with measurable brain morphologic findings in cognitive control areas that can be discovered with non-invasive magnetic resonance imaging (MRI). Patients scheduled for surgery with an age range of 65-75 years of age, will participate in brain diffusion-weighted pseudo-continuous arterial spin labeling (DW-pCASL) and diffusion tensor imaging (DTI), cognitive assessments, and evaluation of a BBB marker from blood (at baseline, at two weeks, and at six months after surgery). All patients will have a brain scan (MRI) within before surgery and two weeks and six months after surgery. During this visit cognitive function will be assessed. Patients will also be asked to participate in a blood draw.
open to eligible people ages 18 years and up
This study will use a digital platform to longitudinally track comprehensive information including patient self-report as well as data that describe the process and outcome of care in the electronic medical record (EMR) of a large representative sample of patients under investigation for SARSCOV2. The objective is to generate knowledge rapidly using digital tools and collaborative sciences to produce real-time data, analysis, and reporting compared to more traditional approaches. An additional goal is to promote an open science approach whereby scientists, with proper approvals and in line with the permissions granted by the participants, have the opportunity to work with data in ways that protects individual privacy but promotes rapid dissemination and implementation of knowledge.

open to eligible people ages 40-75
The purpose of this study is to examine the mechanisms of brain injury contributing to postoperative neurocognitive disorders (PNCD) in an at-risk population (obstructive sleep apnea (OSA)) undergoing surgery. The investigators will enroll 50 OSA patients scheduled for surgery. All patients will have a brain scan (fMRI) within five days before surgery and two days and six months after surgery. During this visit cognitive function will be assessed using the Wide Range Assessment of Memory and Learning (WRAML2) and Montreal Cognitive Assessment (MoCA) tests. Patients will also be asked to participate in a blood draw during the first 2 visits for fMRI (within five days of surgery and two days after surgery). The Confusion Assessment Method (CAM-S) test, will be used to examine postoperative delirium.
