No drug for Alzheimer’s disease does anything but treat symptoms of the degenerative ailment. The first medicine that can do more will be an enormous breakthrough.

Biogen Inc. thinks it has that drug in aducanumab. It’s a treatment the company previously announced was a failure in March, but in a highly unusual move, it is trying to resurrect the medicine and gambling that it can win Food and Drug Administration approval.
