A new drug that protects the blood-brain barrier in mice could totally shake up how we treat Alzheimer’s! Instead of just targeting amyloid plaques (which hasn’t worked that well), this one blocks a specific immune enzyme linked to brain inflammation. The wild part? Mice kept their memory and brain function even after brain injury. It’s early days, but this could mean a whole new way to fight dementia is on the horizon. Fingers crossed for more breakthroughs! #Alzheimers #BrainHealth #ScienceNews #Health
