it has been estimated that more than 1.7 million individuals suffer a traumatic brain injury (tbi) each year. tbi causes secondary biochemical and metabolic changes which contribute to subsequent tissue damage and associated neuronal cell death. two early and delayed events occur after tbi, which results in neurological deficits. primary injury events include the mechanical damage that occur at...
