December 12, 2023 updated by: Sanmai Technologies PBC dba Sanmai

The Effects of Noninvasive Brain Stimulation on Mental States, Behavior, and Electrophysiology

The purpose of the study is to test the effects of brief, low-intensity transcranial focused ultrasound (TUS) on electrophysiological, behavioral, and cognitive markers related to anxiety disorders.

Study Overview

Status

Status

Indicates the current recruitment status or the expanded access status.
Recruiting

Conditions

Conditions

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

Detailed Description

We will test the effects of TUS on self-reported and clinical anxiety states in healthy participants and in those with diagnosed anxiety disorders. Participants in these studies will receive pulsed TUS to the brain regions of interest. We will test whether multiple doses of TUS lead to larger reductions in mental states related to anxiety in comparison to a single dose of TUS.

Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4. Not Applicable is used to describe trials without FDA-defined phases, including trials of devices or behavioral interventions.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Ages Eligible for Study

  • Adult
  • Older Adult

Accepts Healthy Volunteers

Yes

Description

Inclusion Criteria:

  • 18-65 years of age, as verified via photo identification with date of birth.
  • Should be an English speaker, as indicated by being able to read and comprehend the consent form.
  • Experiment 2 : Participants will be included for a past diagnosis of anxiety within the past year.

Exclusion Criteria:

  • Smokes or uses tobacco products or any form of nicotine excessively
  • History of head injury with loss of consciousness for more than 5 min
  • Uncorrected hearing or vision impairment, including color blindness
  • Currently have or history of brain or mental illness judged likely to interfere with testing, including drug and/or alcohol dependence
  • History of epilepsy
  • Brain tumors
  • Takes medications or drugs judged likely to change brain activity, including psychoactive drugs, stimulants, benzodiazepines, and/or others
  • Factors that may lead to poor EEG or fNIRS recordings (e.g., hairstyle)
  • Inadequate sleep
  • Drug, alcohol or prescription drug intoxication, dependence or addiction
  • Pregnancy, or becoming pregnant during the course of the study
  • Mild cognitive impairment or impaired decision making
  • History of migraines

Arms and Interventions

Participant Group / Arm

Participant Group / Arm

A group or subgroup of participants in a clinical trial that receives a specific intervention/treatment, or no intervention, according to the trial's protocol.
Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.
Experimental: Experiment 1
The study will consist of 2 groups. A: no current diagnosis of anxiety or other psychological disorders. B: Current diagnosis of anxiety disorder. Results will be analyzed within and between groups. Participants will answer standardized questionnaires and other similar validated psychological scales. An ultrasound transducer will be placed on their head aimed at the brain region of interest. EEG data will be collected throughout the process. After this process, participants will answer a set of post experiment questions.
Device: Gen0b
The ultrasound will be administered to the brain region of interest.
Experimental: Experiment 2a
Current diagnosis of anxiety disorder is required. Participants will receive an MRI. Participants will answer standardized questionnaires and other similar validated psychological scales. An ultrasound transducer will be placed on their head aimed at the brain region of interest. EEG data will be collected throughout the process. After this process, participants will answer a set of post experiment questions
Device: Gen0b
The ultrasound will be administered to the brain region of interest.
Experimental: Experiment 2b
Experiment 2b will expand on Experiment 2a protocol with multiple visits. Each visit will consist of the same activities as Experiment 2a.
Device: Gen0b
The ultrasound will be administered to the brain region of interest.
