GUARANTEED PASS/ALREADY GRADED A
a trauma induced alteration in mental status (confusion and
amnesia lasting seconds to minutes) that may or may not
involve LOC and does not have focal neurological signs is called
a-ANSWER-mild traumatmic brain injury
What duration of LOC defines severe TBI-ANSWER->12 hours
In addition to LOC, what other characteristics define a severe
TBI-ANSWER-radiographic signs of injury to brain, skull, or
intracranial blood vessels
What 2 population groups are most at risk for severe TBI-
ANSWER-15–24 yeras old men OR 75 y/o men or women
1|P a g e
,Describe head trauma due to direct force-ANSWER-direct
mechanical force (coup) disrupts underlying brain tissue
(parenchyma) causign cell death by necrosis, as well as
inflammatory changes AS WELL AS contrecoup injury which
occurs as a result of the brain hitting the opposit inner surface
of the skull
Which part of the brain is typically injuryed by contrecoup
injuries-ANSWER-temporal and frontal lobes
Damage to the temporal and frontal lobes due to contrecoup
injury generally lead to what type of deficits-ANSWER-memory
and personality change
Which type of trauma rarely leads to countercoup injuries-
ANSWER-frontal trauma
trauma to long subcortical white matter acons as well as
cytoskeletal elements and fatal intracellular influx of calcium is
called what-ANSWER-diffuse axonal injury
2|P a g e
, What is the only method of imaging is able to show DAI-
ANSWER-diffusion tensor imaging (DTI)
What types of injury can result from head trauma? (5)-
ANSWER-direct force, diifuse axonal shearing, intracerebral
bleeding, bleeding within the skull, and foregin object
penetration
Describe the head trauma caused by intracerebral bleeding-
ANSWER-intraparenchymal bleeding nad diffuse cerebral
edema increasing ICP which can lead to transtentorial
herniation
innermost translucent vascualr membrane adhering to cerebral
gyri-ANSWER-pia mater
space between pia and arachnoid mater-ANSWER-
