Rakez Kayed, PhD, associate professor of Neurology, and Bridget Hawkins, PhD assistant professor of Anesthesiology, have filled an important gap in understanding the link between traumatic brain injury and neurodegenerative disorders such as Alzheimer’s disease. Previously, UTMB researchers found a toxic form of tau protein that increases after a traumatic brain injury and may contribute to development of chronic traumatic encephalopathy, a condition experienced by many professional athletes and military personnel.
