The Barrow Neurological Institute is proud of its reputation as a medical research facility and is home to some of the most sophisticated research programs outside of an academic setting in the Southwestern United States. Researchers in the Barrow Neurosurgery Research Center are devoted to learning more about the causes of and treatments for a wide range of disorders, such as stroke, aneurysms, spinal cord injury, and hydrocephalus. Our research has led to treatments that are being used around the world. Within the Department are neurosurgeons who subspecialize in cerebrovascular and skull base, functional and stereotactic, pediatric, spine, tumor, and endovascular neurosurgery.
Physicians, scientists, and expert clinical staff come together with a commitment to developing new techniques for the prevention, diagnosis, treatment, and rehabilitation of neurological illnesses and injuries. The leadership of internationally respected physicians keeps Barrow at the forefront of neuroscience. The compassionate expertise of its extensive staff of nurses, technologists, therapists and support personnel is evident in every aspect of care provided.
Our mission is to advance the knowledge and practice of medicine in neuroscience through basic and clinical research, education of medical professionals, and innovation in clinical techniques and technology.
