Glasglow Coma Scale
Give this one a try later!
Is used to evaluate the severity of TBI. The lower the score, the more severe
the injury and the worse the prognosis
Stage 11 of CTE
Give this one a try later!
Characterized by perivascular p-tau neurofibrillary tangles
Primary injury
,Give this one a try later!
Injuries that directly injure the brain that can cause neural damage, glial
injury, shearing and rotation forces.
Intracerebral hematoma
Give this one a try later!
Occurs when the intracranial bleed occurs directly into the cerebrum (brain
tissue). Commonly occur in the temporal and frontal lobe. It compresses
the brain tissue and cause an increase in intracranial pressure because is an
expanding mass.
Closed (blunt) head injury
Give this one a try later!
The most common focal injury . It occurs when the head hits a hard,
immobile surface or when a rapidily moving object strikes the head like a
baseball bat. The dura remains intact & the cranial contents do not come in
contact with the environment. This injury will likely cause a concussion.
Population at the highest risk for TBI
Give this one a try later!
, Children under 4, adolescents 15-19y/o, and adults 65 and olders. Most
common in men.
Clinical manifestations of subdural hematoma
Give this one a try later!
Headache, drowsiness, restlessness, slowed cognition and confusion.
Symptoms will progress loss of consciousness, respiratory changes and
pupils dilation as ICP increases. All hematoma can compress the brain
tissues, increase ICP, and if not resolved can result in brain herniation
PCS
Give this one a try later!
It occurs in about 80% of ppl with mild and moderate TBI. Women are at
higher risk. Older ones are even at more risks.
