Dr. Diringer is the Director of the Neurology-Neurosurgery Intensive Care Unit and Head of the Neurological Critical Care Section.

Dr. Diringer is a fellow of the American Heart Association (Stroke) and the American College of Critical Care Medicine. He has been repeatedly listed as one of the “Best Doctor’s in America” and “Best Doctor’s in St. Louis.” In 2004 Dr. Diringer was installed as the president of the Neurocritical Care Society.

The Neurology/Neurosurgery Intensive Care Unit serves as our “clinical laboratory.” It is the only unit of its type in the U.S. with on-site PET scanning facilities. The goal of our research efforts is to improve the quality of care delivered to critically ill patients with neurological and neurosurgical disease by focusing on the impact of therapeutic regimes on cerebrovascular hemodynamics and metabolism. It is our hope to settle some of the major controversies presently surrounding the treatment of our patients. These include such therapies as hyperventilation, manipulating blood pressure and the use of osmotic agents.
