Brain & Nervous System Specialists in Arizona

Barrow Neurological Institute in Phoenix is the largest neurosurgery program in the world by case volume. That distinction, measured in operations performed annually, sits inside a hospital in a state that most people associate with retirees and desert scenery rather than neuroscience. But Barrow's scale is a product of deliberate subspecialization over decades, and it has transformed Phoenix into a destination for complex neurological cases that patients once traveled to Cleveland or Boston to receive. Patients with brain tumors, complex vascular malformations, and spinal cord injuries are referred to Barrow from across the western United States and internationally. Arizona's neurology landscape extends well beyond one institution. Banner Sun Health Research Institute in Sun City operates the Brain and Body Donation Program, one of the largest longitudinal studies of neurodegenerative disease in the world, and its research has contributed to major advances in Alzheimer's detection and tau protein pathology. The state's large and growing population of adults over 65, concentrated in Sun City, Prescott, and Green Valley, creates sustained demand for dementia evaluation, Parkinson's management, and stroke care that shows no sign of abating. Rural neurology in Arizona depends almost entirely on telemedicine. When a stroke happens in Payson or Safford, the nearest in-person neurologist may be two hours away. Banner Health's telestroke network and similar programs connect rural emergency physicians to board-certified neurologists via real-time video, enabling the time-critical decision about tPA administration within the treatment window. Arizona's investment in this infrastructure has measurably shortened stroke response times in underserved counties, though the system still strains when rural hospitals lack the imaging capacity to support telestroke protocols.
