"Alzheimer's Drug Successfully Penetrates Brain Barrier Using Sound Waves: Study"

A small study has shown that using focused ultrasound to open the blood-brain barrier is safe and may help Alzheimer's medications reach the brain more effectively. The study involved three patients who received monthly doses of the Alzheimer's drug aducanumab, with one hemisphere of their brains receiving the medication along with focused ultrasound. The treated hemisphere showed a 32% reduction in harmful amyloid beta plaques compared to the untreated hemisphere. While the technique shows promise, further research is needed to understand its long-term effects and potential side effects.
