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 mood disorder, more technically described as “Unspecified Mood (Affective) disorder”. This novel technology focuses beams of ultrasound 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 neuromodulation of the targeted tissue, which alters the reactivity of stimuli and enables a positive shift in mood. While significant work has been accomplished, there is still much to be done before this technology will be widely available.
Advantages
The primary options for treatment of mood disorder include medication.
Focused ultrasound is non-invasive, so it does not carry added concerns like surgical wound healing or infection. It can reach the desired target without damaging surrounding tissue, and it can be repeated, if necessary.
Clinical Trials
A clinical trial in California that was treating patients with mood disorders has been completed.
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 treatment for mood disorders is not yet approved by regulatory bodies or covered by medical insurance companies.
