Summary

This study tests a one-time microsurgery that connects lymphatic vessels in the neck to veins, aiming to improve drainage of waste proteins from the brain. Fifty-nine people with severe Alzheimer's will receive the surgery plus standard medication. Researchers will measure changes in cognitive function and brain scans over 12 months to see if the procedure is safe and effective.

What this could mean

Our plain-language read of the trial. This is informational only — not medical advice or a prediction.

Active substance

Deep Cervical Lymphovenous Anastomosis (a microsurgical procedure to connect lymphatic vessels to neck veins)

What this could lead to

If successful, this could offer a new way to slow cognitive decline in severe Alzheimer's by helping the brain clear toxic proteins.

What could go wrong

This is a very early, small study with no control group, so results may not be reliable. Surgery carries risks like infection or anesthesia complications, and the benefit is unproven.
