Hong Kong Researchers Pioneer Noninvasive ‘Acoustic’ Brain Interface for Parkinson’s

Researchers in Hong Kong have developed a noninvasive brain-computer interface that uses ultrasound to treat Parkinson’s disease and other neurological conditions, potentially bypassing the need for risky surgical implants.

Parkinson’s disease is the world’s second most common neurodegenerative disorder, and its prevalence is rising globally due to aging populations and environmental factors. Currently incurable, the disease relies on drugs and surgery to merely manage symptoms. The new “all-acoustic” system developed by a research team at the Hong Kong Polytechnic University modulates neural circuits using ultrasound waves — offering a novel avenue for treating Parkinson’s, depression and sleep disorders.
