Focused Ultrasound Therapy

Focused 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 dementia. (Please note that Alzheimer’s disease is a specific type of dementia, and is covered under Alzheimer’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 a temporary loosening of the blood brain barrier, which may allow dementia to be treated without surgery. While significant work has been accomplished, there is still much to be done before this technology will be widely available.

The primary options for treatment of dementia include medication, but this is of limited effectiveness.

For certain patients, focused ultrasound might provide a more effective alternative to current treatment. 

Advantages:

  • Focused ultrasound can reach the desired target without damaging surrounding tissue.
  • It can be repeated, if necessary.

Clinical Trials

An existing clinical trial is treating patients with dementia that also have Parkinson’s disease.

Regulatory Approval and Reimbursement

Focused ultrasound treatment for dementia is not yet approved by regulatory bodies or covered by medical insurance companies.
