Researchers just pulled off something wild: they used specially designed nanoparticles to actually reverse Alzheimer’s symptoms in mice—like, memory came back and brain plaques shrank. Instead of only targeting neurons, they fixed the brain’s protective barrier and helped clear out toxic proteins. It’s not a human cure yet, but this could totally change how we think about treating dementia. Imagine if brains could heal, not just decline! #Health #BodyHealth #Alzheimers
