New Alzheimer's Treatment Clears Plaques From Brains of Mice Within Hours

New nanoparticle treatment helps brain to clear toxic Alzheimer’s proteins in mice

meeboonstudio/Shutterstock.comAlzheimer’s is a disease that robs people of their memory, and scientists have long sought ways to stop or reverse its effects. But the blood-brain barrier – the brain’s protective shield – has been both a friend and a foe. While it keeps harmful substances out, it also blocks many treatments from getting in. Now researchers are trying a different approach. Rather than bypassing the barrier, they’re learning to work…

New Alzheimer's Treatment Clears Plaques From Brains of Mice Within Hours

Scientists have repaired a natural gateway into the brains of mice, allowing the clumps and tangles associated with Alzheimer's disease to be swept away. After just three drug injections, mice with certain genes that mimic Alzheimer's showed a reversal of several key pathological features. Within hours of the first injection, the animal brains showed a nearly 45 percent reduction in clumps of amyloid-beta plaques, a hallmark of Alzheimer's disea…
