People with Alzheimer's who start off with worse symptoms and less amyloid in their brain might actually see more amyloid build-up after a special ultrasound treatment opens up the barrier in their brain.

Similar Assertions

Some Alzheimer's patients had a special ultrasound treatment to open part of their brain, and in most of them, brain scans showed less of a harmful protein linked to the disease.

If someone with Alzheimer's has more ups and downs in their memory test scores early on, they might end up with more amyloid buildup in the brain after getting a special ultrasound treatment that opens the blood-brain barrier multiple times.

Doing three brain treatments using focused ultrasound in Alzheimer's patients, two months apart, seems safe and doable, with no serious side effects seen right after the procedures.
