Dr. James Brorson is an expert in the evaluation and treatment of stroke, transient ischemic attack, and cerebrovascular disease. He diagnoses and treats patients with common and unusual causes of cerebrovascular disease--including hypertension, atherosclerosis, carotid artery stenosis, cardioembolic stroke, arterial dissection, and moyamoya disease.Working with colleagues in the sections of neurosurgery, vascular surgery, neuroradiology, and cardiology, Dr. Brorson uses an interdisciplinary approach to decision making and planning therapies to prevent stroke, and evaluating emerging treatments for cerebrovascular disease. He currently participates in clinical trials evaluation balloon angioplasty and stenting for carotid artery disease and percutaneous closure of patent foramen ovale (PFO) for stroke prevention.Dr. Brorson's research efforts focus on understanding why some neurons of the brain seem more vulnerable to degenerative diseases of the nervous system than others. He is …looking at particular mechanisms that may modulate the sensitivity of nerve cells to injury from lack of oxygen or cellular injury, with the aim to understand how neurons can be protected in neurodegenerative diseases.
