Brief Title ICMJE | Low Intensity Focused Ultrasound for Mild Cognitive Impairment and Mild Alzheimer's Disease | ||||||||
Official Title ICMJE | Modulation of Hippocampal Circuitry and Memory Function With Focused Ultrasound in Amnestic MCI | ||||||||
Brief Summary | The goal of this study is to investigate whether Low Intensity Focused Ultrasound Pulsation (LIFUP) targeting a part of the brain involved in memory will have an affect on brain activity and whether it may improve memory in people with Mild Cognitive Impairment and Mild Alzheimer's Disease. The main questions the study seeks to answer are:
Participants in this study will complete MRIs and memory testing, and receive Low Intensity Focused Ultrasound to a part of their brain involved in memory (the entorhinal cortex). |
||||||||
Detailed Description | This is a proof of concept trial of Low Intensity Focused Ultrasound Pulsation (LIFUP) targeting the entorhinal cortex in patients with amnestic MCI and Mild Alzheimer's Disease. Participation in the study will entail one Zoom intake session, three in-person sessions and three remote Zoom follow-up sessions over the course of about five weeks. The in-person sessions will take about 5 hours for the first and 3 hours for the following two. The Zoom intake session will take 1-2 hours, and the Zoom follow-up sessions will take about 2 hours each. Participants will be asked to complete questionnaires and tests of learning and memory, have their blood drawn, undergo painless ultrasound stimulation to a part of their brain related to memory, and complete MRI scans of their brain. LIFUP will be administered inside of the MRI scanner, so that we can measure changes in brain activity in real-time. At the start of the study, you will be randomly assigned to one of four different groups that determines the amount of LIFUP stimulation you will receive. You have an equal chance of being assigned to each group. Participants in one of the three active stimulation groups will receive either 1 dose, 2 doses, or 3 doses of LIFUP at their second in-person session, and will receive the same dose again at their third in-person session. Participants in the placebo group will receive no LIFUP stimulation at either MRI/LIFUP session (in-person visits 2 and 3). However, if at the end of our study, the treatment has been shown to be effective, and you were a placebo subject, we will offer you a free session using the most effective dose. |

Study Design ICMJE | Allocation: Randomized Intervention Model: Parallel Assignment Intervention Model Description: Subjects are randomly assigned to one of four treatment dosage conditions: 0, 1, 2 or 3 treatments at each MRI-LIFUP session. After 2 weeks, a second dose is administered with the same dosage level for each subject. Memory assessment occurs once at baseline and remotely after each treatment at the onset of the optimal time window (48 hours) for LIFUP-induced change based on prior data. Finally, after 2 weeks, memory is again assessed. Alternate forms are used for the primary outcome measures to avoid practice effects. Masking: Double (Participant, Outcomes Assessor)Masking Description: Participants and the participants' caregivers will be blinded to arm assignment. Additionally, the person administering memory testing will be blinded to assignment. Primary Purpose: Treatment
