This is the real deal, not “we cured Alzheimer’s in mice for the thousandth time”.
That said, it only slows the disease a bit, so it’s not that meaningful for patients yet. But, given that three years ago we didn’t have ANY disease-modifying drugs, I still find that very encouraging.
Now, the big question of course is, if we give this before symptoms happen (amyloid deposits start ten+ years before clinical symptoms), does it prevent the disease? But this will have to wait for a few more years.
