Why is focused ultrasound important for Alzheimer's?
The treatment being tested, known as focused ultrasound, opens up the blood-brain barrier, the semipermeable membrane that surrounds blood vessels in the brain. This barrier is necessary to keep out germs, but it also prevents potential Alzheimer's drugs from reaching the brain. “This is one reason why we think past medication treatments for Alzheimer's have not been effective,” says neurosurgeon Ali Rezai, director of the Rockefeller Neuroscience Institute at the WVU School of Medicine.

One theory is that the ultrasound triggers an immune response, which leads the brain to clear out the plaques and tangles as waste. “I explain it to people as, ‘We opened Judi's attic door and her immune system looked up and saw all these cobwebs and decided to grab some Swiffers and clean them all out,'” Mark says.
