What it is

Levetiracetam is an inexpensive prescription drug for seizures. A Northwestern team found it slows how neurons recycle parts of themselves, steering them away from making amyloid-beta 42, the form that clumps into plaques. It worked in mice and in human cells, and the researchers say it would have to start years before symptoms.
