Flashcards in Traumatic Brain Injury Deck (14):
- Application of external physical forces to brain that produce immediately apparent physiological disruption of brain function and/or structure; some kind of functional disability results
4 examples of traumatically induced physiological disruptions of brain function
- loss of consciousness
- posttraumatic amnesia
- alteration in mental state
- focal neurologic deficits
TBI is leading cause of what 3 things?
Coma, trauma-related disability, brain damage in kids/YA's
What are the two types of TBI?
Closed - acceleration/deceleration
Open - perforation of skull, dura mater
What motion to the brain can really damage it?
Translation, rotation, and angular acceleration
(not related as much to compression and linear motion as you might think)
What type of damage can strain and shear forces to brain produce?
Regardless of where the injury occurs on the head, which lobes of the brain are most commonly affected?
Anterior, frontal, and temporal lobes
In diffuse (multifocal) axonal injury, what part of brain is most affected?
Upper brainstem, white matter of cerebrum (parasaggital), corpus callosum, gray-white junctions of cerebral cortex
TBI can lead to what kind of cascade?
What qualifies a TBI as severe?
What qualifies a TBI as moderate?
What qualifies a TBI as mild?
What is LOC range for mild TBI?
