Deep Brain Stimulation clinical trials at University of California Health
3 in progress, 2 open to eligible people
open to eligible people ages 55 years and up
The purpose of the proposed study is to determine the feasibility of brief brain stimulation, using a device called Low Intensity Focused Ultrasound Pulsation (LIFUP), for persons with mild cognitive impairment (MCI) or mild (early-stage) Alzheimer's disease (AD). As a secondary aim, the investigators will explore whether this brief intervention is associated with improvements in cognitive functioning immediately and one week following the intervention. Subjects will be randomly assigned to one of two experimental groups: either the LIFUP administration will be designed to increase the activity of neurons in a certain part of the brain or decrease the activity of neurons. The investigators will study up to 8 subjects with MCI or mild AD. Initially, subjects will undergo a screening assessment with a study physician to determine medical and psychiatric history, establish AD diagnosis, and undergo a blood draw, if standard recent labs for dementia and EKG are unavailable. Subjects that meet criteria and agree to participate in the study will undergo a follow-up visit. In the baseline measurement visit, participants will first undergo neuropsychological testing. Participants will be randomly assigned to one of two LIFUP pulsing paradigms. Participants will then be administered four successive LIFUP treatments while the participants are in a functional magnetic resonance imaging (MRI). Sixty minutes following the administration, participants will undergo a second neuropsychological test. A final follow-up assessment will be administered at one week.

The study's aim is to better understand motivation and value-based decision making in Parkinson's patients through neurophysiology using Medtronic's Percept PC DBS device.
Sorry, in progress, not accepting new patients
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.
