A new ultrasound “helmet” may provide a non-invasive alternative to deep brain stimulation (DBS) for Parkinson’s and other neurological conditions, a study shows.
The device can target brain regions 1,000 times smaller than conventional ultrasound, potentially treating Parkinson’s tremors without surgery. It could also help with Alzheimer’s, depression, Tourette syndrome, chronic pain, and addiction. Unlike DBS, which requires electrodes to be implanted deep in the brain, the helmet delivers precise mechanical pulses externally.
Developed over a decade by teams at Oxford University and University College London, the helmet fits inside an MRI scanner and uses 256 sources to direct ultrasound waves with high accuracy. In tests on seven volunteers, it successfully targeted a region the size of a grain of rice in the visual pathway, producing measurable effects in the connected brain areas.
“This proof of concept represents a fundamental neuroscience milestone,” said Prof Elsa Fouragnan of Plymouth University. The research team aims to expand testing to brain regions linked to Parkinson’s, stroke recovery, schizophrenia, pain, and depression.
Future improvements may incorporate AI, allowing patients to use the helmet at home without MRI guidance, with the ultimate goal of creating a practical clinical tool that could complement or replace invasive brain implants.
