"There is evidence of a 'clinical void,' with clinicians on one side and people with MS and other conditions on the other that doesn't usually exist regarding therapies that people with MS are using," said Allen C. Bowling, MD, PhD, director of the NeuroHealth Institute and clinical professor of neurology at the University of Colorado, in Aurora. His [...]
