Dr. Kummer’s research program is focused on understanding the mechanisms underlying neuronal trauma and degeneration during and following acute brain injury. Dr. Kummer carries out this research both in the laboratory, and in the Neurointensive Care Unit, where he is an attending. Brain injury is a leading cause of death and disability in the United States. Sudden brain injury usually takes one of two forms: traumatic or vascular. Traumatic brain injury occurs when the head receives a sudden external impact, possibly from an improvised explosive device, a car windshield, or even a barreling linebacker. Victims of such events may develop brain trauma near the site of impact, such as brain contusions, as well as ripple effects that damage the brain diffusely. Diffuse injury most importantly damages the axons that make up the brain’s wiring. Vascular brain injury takes the form of vascular blockage, causing strokes, and the far more deadly vascular rupture, which causes brain hemorrhages. Although an enlarging bleed causes obvious injury to adjacent brain, very little is known about the diffuse brain injury that likely underlies persistent coma and long-term cognitive and emotional impairment after brain hemorrhage. New results from Dr. Kummer’s group suggest that axon injury, so crucial in traumatic brain injury, also occurs during hemorrhagic brain injury. Dr. Kummer’s research is aimed at exploring this connection through the use of advanced brain imaging and neuromonitoring techniques available both in the laboratory and in the clinical setting.
