A new ultrasound “helmet” could provide a non-surgical alternative for treating neurological conditions, including Parkinson’s disease, depression, Tourette syndrome, Alzheimer’s, and chronic pain.
The device can target brain regions 1,000 times smaller than conventional ultrasound, potentially replacing deep brain stimulation (DBS), which requires invasive electrode implants. A study in Nature Communications demonstrated the helmet’s ability to focus on regions 30 times smaller than previous deep-brain ultrasound systems.
Researchers tested the system on seven volunteers, directing ultrasound waves to the lateral geniculate nucleus, a visual processing region, achieving highly precise results. Modulating the area produced lasting effects in the visual cortex, suggesting similar benefits could be possible for motor control regions in Parkinson’s patients.
Developed over a decade by teams at Oxford University and University College London, the helmet integrates with MRI scanners and is designed for patient comfort. Future versions may use AI to allow home use without MRI guidance. The developers aim to refine it into a practical clinical tool that could complement or replace invasive brain implants.
