Breakthrough Alzheimer's drug reverses symptoms in mice
Scientists from Spain and China have developed a nanoparticle-based drug that actually reversed Alzheimer's symptoms in mice, according to a 2025 study published this week.
The treatment repairs the brain's protective barrier—often damaged in Alzheimer's—helping clear out harmful amyloid-beta proteins that build up and cause memory problems.
This could be a big step toward future treatments for people.
Drug restores blood flow, reduces inflammation
Mice given the new drug not only had fewer amyloid-beta proteins, but also showed major improvements in thinking and behavior—even older mice bounced back months after treatment.
The drug works by restoring healthy blood flow and reducing inflammation in the brain.
While it's early days and more research is needed before human trials, this research offers real hope for tackling Alzheimer's at its roots.
