It cleared amyloid plaques completely from the brain in some participants, who were then taken off the drug.

If true, this is genuinely exciting news. It’s not a complete “you’re cured” solution, but it’s better than anything in the past has been able to accomplish. It’d be more akin to cancer remission, where patients will need to be screened every few months to ensure more plaque isn’t starting. But in the interim, they don’t need to continue actively receiving treatments. Just like how cancer survivors go back for scans even after getting the all-clear, because the chances of the cancer returning some time in the future are extremely high.
