Among children with moderate to severe traumatic brain injury, some experience long-term brain degeneration following injury. However, not all children that experience traumatic brain injury (TBI) have progressive cognitive decline, and CT scans do not reliably predict the likelihood for recovery. UCLA researchers discovered a biomarker for children with traumatic brain injury that detects which individuals might be at risk for ongoing cognitive decline. Researchers measured speed of brain signals passing from one hemisphere of the brain to the other, finding that children that experience ongoing cognitive decline show slower brain signals between hemispheres. This biomarker has the potential to prevent further cognitive decline among children.
