SAN FRANCISCO--(BUSINESS WIRE)--In a new study published today by NeuroInsights and the Neurotechnology Industry Organization, nine metropolitan regions around the world are leading the way in innovating treatments for the largest unmet medical market, brain-related illness. By developing the necessary infrastructure to discover and develop neurotechnology - drugs, medical devices, biologics, cell-based therapeutics, and diagnostics for the brain and nervous system, these regions are helping spur local economies while fighting many of the most vexing medical problems of modern times, such as Alzheimer’s disease, depression, obesity, stroke, epilepsy and chronic pain.
