Modulation of Hippocampal Circuitry and Memory Function With Focused Ultrasound in Amnestic MCI
open to eligible people ages 50-90
This study is a proof of concept/proof of mechanism study addressing the hypothesis that Low Intensity Focused Ultrasound Pulsation (LIFUP) targeting the entorhinal cortex can (A) successfully target and increase activity in the entorhinal cortex and functionally connected brain regions (B) improve connectivity of memory networks (C) improve memory for information (D) have a dose-dependent effect on memory and brain activity. A secondary objective is to determine the relationship between blood-based AD biomarkers and LIFUP treatment outcomes, and the relationship between magnitude of HC volume decline and LIFUP treatment outcomes.

Blood Brain Barrier Dysfunction and Postoperative Neurocognitive Disorders
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.

Postoperative Neurocognitive Disorders
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.

Innovative Support for Patients With SARS-COV2 Infections (COVID-19) Registry (INSPIRE)
Sorry, in progress, not accepting new patients
The Innovative Support for Patients with SARS COV-2 Infections Registry (INSPIRE) study is a CDC-funded COVID-19 project to understand the long-term health outcomes in recently tested adults, both negative and positive, who have suspected COVID symptoms at the time of their test. Participants will complete short online surveys every 3 months for 18 months, share information about their health using a secure web-based platform, and are compensated for their time.
