Trial summary

Objective: Preliminary studies show that low intensity focused ultrasound (LIFU), a new type of non invasive brain stimulation, may be able to reach deep structures of the brain involved with depression and anxiety, that remain inaccessible using current forms of non-invasive brain stimulation with precision.

About this study

Objective: Preliminary studies show that low intensity focused ultrasound (LIFU), a new type of non invasive brain stimulation, may be able to reach deep structures of the brain involved with depression and anxiety, that remain inaccessible using current forms of non-invasive brain stimulation with precision. In this study, the investigators will test if this technique can be used to change brain activity in areas that are connected to depression and anxiety symptoms. The primary objectives of this study are to test the safety and tolerability of LIFU, evaluate the feasibility of using LIFU to reduce brain activity, and evaluate the feasibility of simultaneous fMRI-LIFU. If the results of this study are positive, what the investigators learn will serve as a strong foundation for the future development of innovative treatments for a variety of psychiatric disorders.

Research Procedures: 25 veterans will be recruited. Visits will take place at the VA Providence Healthcare System. During some visits, healthy and patient participants may undergo clinical and research neuroimaging, neuropsychological testing, complete questionnaires, and participate in clinical/neurological assessments. Healthy veterans will not receive LIFU and will only attend 2 study visits. Patients are expected to attend up to 8 visits over 6 weeks. However, some may require up to 6 extended follow-ups after visits 5 or 8, in which case they would attend a total of 11 or 14 visits over 6 months. Two patient visits will include the LIFU application, following FDA safety guidelines. Patients will be assigned either to an experiment in which LIFU stimulation will be delivered immediately prior to a task or to an experiment in which stimulation will be delivered during the task. Within each experiment, patients will be assigned to first receive either LIFU stimulation to the study target or anatomical control. Study staff, but not participants will know which location is being targeted in case safety concerns arise. Safety assessments will be conducted at follow-up visits. A clinician will be available during LIFU administration /follow-up visits. Assuming no injury or other concerns are present, patients will then repeat this process again, receiving stimulation targeting other brain area not previously selected.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Incidence of LIFU-related adverse events as assessed by clinical MRI

    MRI safety and monitoring will be determined through the review of clinical MRIs. The clinical MRI will be used to detect possible LIFU-induced injury including edema or other injury and microvascular damage. While the investigators believe hyperacute injury to be unlikely, scans at 24 hours and 1-week will be used to monitor for later evolving injury. If injury is detected on any participant at any stage of the study, the investigators will halt all study procedures.

    Measured: up to 6 months post LIFU

  2. Incidence of LIFU-related adverse events as assessed by neurological examinations

    Neurological exams will be used to detect any possible LIFU-induced neurological changes.

    Measured: up to 6 months post LIFU

  3. Incidence of LIFU-related adverse events as assessed by neuropsychological testing

    The investigators will evaluate safety using standardized neuropsychological tests at baseline, 24 hours, and 1-week post LIFU. The Repeatable Battery for the Assessment of Neurocognitive Status (RBANS) will be used to measure attention, language, visuospatial/construction, immediate, and delayed memory and to measure any possible LIFU-induced changes across these domains.

    Measured: up to 6 months post LIFU

  4. Perfusion Arterial Spin Labeling (ASL) fMRI Signal throughout Brain

    Perfusion ASL fMRI data will be collected before and after sonication. Analyses will assess the statistical relationship between ASL signal throughout the brain pre and post sonication.

    Measured: change from baseline to following sonication

  5. BOLD fMRI Signal

    BOLD data will be collected before, during, and following LIFU sonication. Analyses will assess any changes in BOLD signal in the brain following sonication.

    Measured: change from baseline to following sonication

  6. Resting state functional connectivity

    Resting state data will be collecting before, during, and following LIFU sonication. Analyses will assess any functional connectivity changes in the brain following sonication.

    Measured: change from baseline to following sonication
