Researchers reveal TBI findings at conference
At the American Institute for Medical and Biological Engineering conference February 20th two researchers revealed data on their individual studies and findings related to detecting traumatic brain injuries. Marilyn Kraus, associate professor of psychiatry and neurology at the University of Illinois at Chicago, talked about how using Diffusion Sensor Imaging to look at white brain matter, differences appeared that correspond with cognitive and behavioral issues. She Concluded, that if the white brain matter is studied closely it could help differentiate between PTSD and mild TBI symptoms. While using the Diffusion Sensor Imaging she found that scans of people with mild TBI were “significantly different” from normal scans. The differences could also point to future problems, such as epilepsy or dementia. The second is David Hovda, professor of surgery at the University of California. He reported that a closer look at brain activity showed that those presenting with brain injuries burn lactate for energy as their metabolic rate declines. This suggests that perhaps a metabolic therapy through an IV might be important for treating brain injuries. A normal brain uses glucose for energy. “Fuel is dictated by the needs of the tissue, not by what we think it needs,” Hovda said. “TBI victims tend to come in hyperglycemic, so doctors tend to keep insulin levels low. We may need to look at it differently.” Both researchers present potentially valuable detection and treatment options for patients with a traumatic brain injury.
