Focused Ultrasound Therapy

Clinical Trials SquareFocused ultrasound is an early-stage, non-invasive, therapeutic technology with the potential to improve the quality of life and decrease the cost of care for patients with Huntington’s disease. This novel technology focuses beams of ultrasound energy precisely and accurately on targets deep in the brain without damaging surrounding normal tissue. Where the beams converge, the ultrasound produces precise ablation (thermal destruction of tissue) enabling non-invasive treatment of the movement disorders associated with Huntington’s disease. It is important to note that this does not treat the underlying genetic cause of Huntington’s disease. However, it can lessen the severity of the motor symptoms which can be very debilitating.

For certain patients, focused ultrasound could provide a non-invasive alternative to medications that would enable symptom relief without the medication-induced side effects.

Clinical Trials

A clinical trial is assessing the use of focused ultrasound to treat the movement disorders in patients with Huntington’s disease. Please note that this trial is only open to residents of Canada.

Regulatory Approval and Reimbursement

Focused ultrasound treatment for Huntington’s disease is not yet approved by regulatory bodies or covered by medical insurance companies.

Preclinical Laboratory Studies

Preclinical studies are investigating focused ultrasound’s potential to treat the underlying genetic cause of Huntington’s. Focused ultrasound can temporarily open the blood-brain barrier (BBB) to improve the delivery of genes, stem cells, or other neuroprotective and/or neurorestorative drugs that could potentially be important in treating Huntington’s.
