Focused Ultrasound Therapy
Focused ultrasound is a noninvasive therapeutic technology with the potential to improve the quality of life and decrease the cost of care for patients with depression. This novel technology focuses beams of ultrasonic energy precisely and accurately on targets deep in the brain without damaging surrounding normal tissue.
How it Works
Where the beams converge, focused ultrasound produces thermal ablation, meaning that the targeted tissue is heated and destroyed where the beams converge. Additional research is using neuromodulation, where lower intensity focused ultrasound is used to alter the activity of targets to improve depression.
Advantages
Current treatments for depression include medications, electroconvulsive therapy, surgery (radiofrequency or laser ablation, deep brain stimulation), or stereotactic radiosurgery (gamma knife, linear accelerator), all of which have limitations and side effects.
Focused ultrasound has the potential to provide an alternative to invasive surgery or radiosurgery via precise thermal ablation, or to augment drug therapy.
Focused ultrasound is noninvasive – no incisions, holes in the skull, electrodes in the brain – and therefore has reduced risk for infection and blood clots. It also enables precise targeting and minimizes damage to non-targeted, healthy brain. Focused ultrasound can also be a complement to drug therapy, enabling enhanced delivery of therapies into the brain via temporary opening of the blood-brain barrier.
Clinical Trials
A clinical trial in Tulsa Oklahoma is using low intensity focused ultrasound to improve the communications in the brain for patients with treatment resistant depression.
A clinical trial in Utah is using low intensity focused ultrasound to treat patients with depression.
A clinical trial in South Carolina is using low intensity focused ultrasound to treat patients with treatment resistant depression.
A clinical trial in Ontario, Canada is using the next generation dome helmet to treat patients with treatment resistant depression.
A clinical trial in France is using low intensity focused ultrasound to treat patients with treatment resistant depression.
A clinical trial in Rhode Island is using neuromodulation to the amygdala to treat depression.
A clinical trial in Los Angeles is treating depression. This trial is recruiting patients by invitation.
The Foundation updates these pages regularly, but with the increasing number of clinical trials, we want to be sure that our audience has the latest information available. Therefore, we also added the website search information for the above trials. If you click here, it will take you to the latest information available from https://www.clinicaltrials.gov/.

Regulatory Approval and Reimbursement
Focused ultrasound is only approved by for the treatment of depression in Korea. Outside of the South Korean National Health Insurance System, we are not aware of this treatment reimbursed by any other medical insurance providers.
