Nanostructure-Assisted Ultrasound Shows Potential for Parkinson's Treatment

Researchers at The Hong Kong Polytechnic University have developed a new, less invasive treatment for Parkinson's disease using low-intensity ultrasound combined with hollow silica nanostructures. This method achieves chronic, localized brain stimulation by targeting specific areas like the motor cortex and subthalamic nucleus, offering a potential alternative to surgery or inconsistent medication.

Unlike previous nanoparticle approaches that lacked stability, these nanostructures persisted in mouse models for over nine weeks while remaining responsive to ultrasound. This breakthrough allows for repeated, precise stimulation of neuronal populations without genetic modification or intracranial administration, marking a significant advancement in non-invasive neuromodulation for movement-related neurological disorders.
