Flashcards in Traumatic Brain Injury Deck (14):
1
Define TBI.
- 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
2
4 examples of traumatically induced physiological disruptions of brain function
- loss of consciousness
- posttraumatic amnesia
- alteration in mental state
- focal neurologic deficits
3
TBI is leading cause of what 3 things?
Coma, trauma-related disability, brain damage in kids/YA's
4
What are the two types of TBI?
Closed - acceleration/deceleration
Open - perforation of skull, dura mater
5
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)
6
What type of damage can strain and shear forces to brain produce?
Traumatic axonopathy
7
Regardless of where the injury occurs on the head, which lobes of the brain are most commonly affected?
Anterior, frontal, and temporal lobes
8
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
9
TBI can lead to what kind of cascade?
cytotoxic cascade
10
What qualifies a TBI as severe?
GCS: 3-8
11
What qualifies a TBI as moderate?
GCS: 9-12
12
What qualifies a TBI as mild?
GCS 13-15
13
What is LOC range for mild TBI?
less than 30 minutes
