Symptom scales to diagnose and manage concussion can be subjective
According to the (CDC), between 1.6 and 3.8 million athletes will experience a sports-related mild traumatic brain injury (mTBI) or concussion each year. Despite increased public awareness, clinical guidelines still rely on subjective symptom scales to diagnose and manage concussions. Furthermore, there are currently no biological tests to diagnose mTBI.
Biomarkers found in saliva may distinguish mTBI and parallel symptom recovery
Research we are conducting in collaboration with Penn State College of Medicine and SUNY Upstate Medical University, aims to change that. By analyzing brain-derived biomarkers found in saliva, we have developed a novel diagnostic test for concussion. These biomarkers can confirm mTBI when run through our proprietary artificial intelligence platform.
Results of this research have been published in the journals JAMA Pediatrics, the International Journal of Molecular Sciences, and Clinical Translational Medicine. In addition, we were recently awarded a $2.3 million grant from the NIH* to further the development of this saliva-based test.
