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

14

What is PTA range for mild TBI?

less than 1 day
