Ultrasound enhances brain's waste removal for disease research.

Researchers have developed a noninvasive, nonpharmaceutical method to enhance the glymphatic transport in the brain, known as focused ultrasound combined with circulating microbubbles (FUSMB), which amplifies the effects of ultrasound waves on blood vessels, facilitating the removal of metabolic waste and distribution of nutrients. This breakthrough could open new avenues for studying brain diseases and functions. It also holds promise in mitigating neurodegenerative diseases like Alzheimer’s and Parkinson’s by enhancing waste clearance in the brain.
