Define TBI-ANSWER-Blow jolt or penetrating injury to the head that disrupts brain function Severity ranges from mild of brief change in mental status to severe prolonged changes Can cause behavior, emotional, and personality disturbances Epidemiology of TBI-ANSWER-15–24yr at time of injury Greatest risk 10 or 74 Causes –50% MVA –25% Falls –15% assault –10% Sports What is the MOI of TBI-ANSWER-External force hitting head hard enough to cause brain movement with and without skull fracture –Brain tissue makes direct contact with an object (Acceleration injuries, penetrating objects, blast injuries) Primary Damage from TBI-ANSWER-Contusions Hematomas DAI Penetrating objects Blast injuries Describe contusions of the brain-ANSWER-Bruise or bleeding on the brain – collecting in extracellular matrix from bursting of capillaries Occipital blows are more likely to cause contusions May be associated with lacerations in areas in which the cranial vault is irregular (anterior lobe, under temporal or frontal lobe) What cranial nerves can be damaged in a TBI-ANSWER-Optic Vestibulocochlear Oculomotor Abducens Facial Describe an epidural hematoma-ANSWER-Between Duramater and skull Usually seen in adults Skull fracture common I/M lucideness Can result in death Describe a subdural hematoma-ANSWER-Between Duramater and soft tissue of the brain Acceleration/deceleration injuries –Bridging veins to the superior sagital sinus are torn Weakness, lethargy can become life threatening Symptoms from slow bleed may not be present for weeks What is DAI-ANSWER-Shearing of the axons –Different areas of the brain have different densities causing unequal acceleration, deceleration and rotation Most common MOI causing mod–severe TBI May cause coma May cause abnormal posturing of extremities and autonomic dyfunction Describe Penetrating injuries (low vs high velocity)-ANSWER-Low velocity objects damage tissue they directly contact
