Your last NeuroBrief: Diet and dementia, another rejected Alzheimer’s therapy, positive ASD news, and the nefarious molecule behind most brain disorders

A neurological tug-of-war is taking place between patients, physicians, and the FDA. The agency (or its committees) keeps rejecting Alzheimer’s therapies (for good reason), but patients and physicians keep sounding the alarm (also for good reason), claiming that any therapy that poses even a modest benefit is sorely needed for a condition that affects millions….

Controversy around Biogen’s novel Alzheimer’s treatment. Plus, a surprising verdict for cannabis and pain control, and a new cancer drug pulls double duty for MS patients
