Cognitive Outcomes After Mild Traumatic Brain Injury

Mild traumatic brain injuries (mTBIs) may lead to adverse cognitive and neuropsychiatric outcomes. The pathways that lead to adverse cognitive outcomes remain to be scientifically elucidated. A prospective cohort study of 656 participants enrolled in the Transforming Research and Clinical Knowledge in TBI (TRACK-TBI) study found that at one year, 13.5% of participants with mTBI had poor cognitive outcome compared to 4.5% of controls, highlighting the need for better understanding of the mechanisms leading to poor cognitive and functional outcomes after mTBIs and interventions to optimize cognitive recovery.
