Translational Traumatic Brain Injury Laboratory
Traumatic brain injury (TBI) is a neurodegenerative disease that is induced by forces applied to the brain, and is a common consequence of motor vehicle accidents, slips and falls, and sports and military injuries. TBI is a leading cause of death and morbidity worldwide, and there is no intervention known to improve long-term outcomes in TBI patients. The overall objective of the translational TBI laboratory is to improve our understanding and treatment of this devastating condition. Research projects involve studying the underlying pathophysiological mechanisms of TBI, TBI biomarkers, and potential treatments by utilizing a translational research approach that incorporates both animal models and patients.
A particular research interest is mild TBI (mTBI), often referred to as concussion. Concussion accounts for the large majority of TBI cases, and is now recognized as a serious medical and societal issue. Of particular concern are individuals at high risk of suffering multiple mTBIs, such as athletes and soldiers, since emerging evidence suggests that repeated mTBIs are associated with long-term neurological consequences and neurodegenerative disease. Unfortunately, it is not known why these long-term effects occur or how they can be prevented. We are currently conducting studies in amatuer and professional athletes, as well as in internationally unique animal models, to provide insight into questions surrounding concussions.
TBI is also associated with the onset of other neurodegenerative diseases including epilepsy, motor neuron disease/amyotrophic lateral sclerosis, and polytrauma. However, the causes and pathophysiological mechanisms of these common conditions, as well as their relationship with TBI, are not well known, nor are there effective interventions for these debilitating diseases. Consequently, there is a great need for these serious medical concerns to be addressed. We have a number of research projects related to the ongoing study of these issues.
