The brain is an astonishingly complex organ. Injury to the brain in the form of traumatic brain injury (TBI) can cause learning and memory problems in the short-term and dementia in the long-term. Over 1.7 million individuals experience TBI in the United States every year. Unfortunately, there are currently only symptomatic treatments for TBIs. We talked to Dr. Susanna Rosi, Associate Professor at UCSF, about her research into new treatments for TBIs.
