Cognitive Impairment clinical trials at UC Health
5 in progress, 2 open to new patients
“Research evaluating memory and thinking ability”
open to eligible people ages 18 years and up
Prospective trial of low frequency deep brain stimulation of the ventral subthalamic nucleus to improve cognitive performance in patients with advanced Parkinson's disease. All study participants have undergone DBS implantation surgery as part of their routine care for motor manifestations of Parkinson's disease. In this study, a temporary low frequency period of stimulation will be applied to determine its effects on cognition.

“Helping caregivers care for people with dementia”
open to eligible people ages 21 years and up
The purpose of this study is to develop and implement a culturally-appropriate intervention to reduce stress in Vietnamese dementia caregivers. A pilot intervention will be done to test the feasibility and acceptability of the intervention in a community setting. This will be done by randomly assigning a family triad (primary caregiver, secondary caregiver, and their care recipient) into an active intervention or a control condition and monitoring findings at baseline, post-intervention, and at three months.The intervention will consist of multiple components -enhanced psycho-education that includes discussion of Alzheimer's Disease (AD) and cultural impacts on beliefs about dementia and caregiving, management of problem behaviors, facilitation of support seeking, and mindful Tai Chi. A secondary caregiver who the primary caregiver identifies as providing him/her with the most support will be invited to join all components, but the intervention will be flexible depending on caregivers' needs/preferences. The care recipient is not required to join the sessions but will be able to if he/she or the family wishes. During the intervention, community partners will provide respite care for the care recipient.

Hippocampus and medial temporal lobe (MTL)-dependent memory is impacted by a wide range of psychiatric and neurologic conditions. These cognitive limitations often result in limited functional abilities for patients. Currently available pharmacologic and behavioral treatments are somewhat controversial and have minimal evidence-based effectiveness. Recently, deep brain stimulation was used to modulate MTL activity and subsequently improve memory performance. However, such implantable devices require neurosurgery with major associated health risk. At present, there are no publications reporting non-invasive neurostimulation targeting MTL regions to improve memory. The central hypothesis of this project is that non-invasive, low intensity focused ultrasound pulsation (LIFUP) can selectively increase regional MTL activity and thus be used as a cognitive neural prosthetic capable of improving memory performance. The aims of this study focus on whether LIFUP can increased blood oxygen level dependent (BOLD) activation in the entorhinal cortex and functionally associated regions, whether this increased activation is greater using short train or long train LIFUP parameters, and whether this LIFUP-induced activation, when applied during learning, results in improved memory.
Memantine Hydrochloride and Whole-Brain Radiotherapy With or Without Hippocampal Avoidance in Reducing Neurocognitive Decline in Patients With Brain Metastases
Sorry, in progress, not accepting new patients
This randomized phase III trial compares memantine hydrochloride and whole-brain radiotherapy with or without hippocampal avoidance in reducing neurocognitive decline in patients with cancer that has spread from the primary site (place where it started) to the brain. Whole brain radiotherapy (WBRT) is the most common treatment for brain metastasis. Unfortunately, the majority of patients with brain metastases experience cognitive (such as learning and memory) deterioration after WBRT. Memantine hydrochloride may enhance cognitive function by binding to and inhibiting channels of receptors located in the central nervous system. Radiation therapy uses high energy x-rays to kill tumor cells and shrink tumors. Using radiation techniques, such as intensity modulated radiotherapy to avoid the hippocampal region during WBRT, may reduce the radiation dose to the hippocampus and help limit the radiation-induced cognitive decline. It is not yet known whether giving memantine hydrochloride and WBRT with or without hippocampal avoidance works better in reducing neurocognitive decline in patients with brain metastases.

This study aimed to pilot test a non-pharmacological (behavioral) treatment program targeting improved cognition through improving 24-h sleep-wake cycle in people with mild cognitive impairment (MCI) or mild Alzheimer's disease. A treatment program incorporating bright light therapy and a modified cognitive behavioral therapy for insomnia will be developed to address 24-hour patterns of sleep. We will then pilot test its feasibility and explore its preliminary effects on improving sleep/napping and cognition in patients with MCI or mild Alzheimer's disease.
