Once again, the Food and Drug Administration made a surprise move regarding an experimental medicine from Biogen — and Wall Street is reacting with a mix of skepticism and uncertainty about not only the prospects for the drug, but other issues concerning the agency, drug developers, and patients.

There is also uncertainty about FDA machinations and the broader implications for tackling central nervous system diseases.
