Mild traumatic brain injury (TBI) is the most common type of brain injury. Post-mild TBI disability could stem from cognitive, physical, psychological and social dysfunction which resulted in significant disability and unemployment. Cognitive impairment post traumatic brain injury is due to the disruption of brain vascular bed and microstructural damage. Currently, there is no specific therapy for individual with mild TBI. Neuropsychological assessment and early management immediately after mild traumatic brain injury have been shown to reduce long term cognitive disability. In-vitro and in-vivo studies showed a better recovery of cognitive function after administration of exogenous lactate in traumatic brain injury.
