TBI & CTE Flashcards
When does a TBI occur?
when a force to the head causes neuropathologic damage and impairment of brain function
What are the two types of TBI?
- mild
- severe
what TBI is also named a concussion?
mild
What is a CTE?
- a progressive neurodegenerative disorder usually caused by repetitive head trauma
T or F: tbi decreases the risk of developing CTE
false, it increases chance
What is the leading cause of death and disability in individuals less than 44 years old?
TBI
What gender has more TBIs?
men
What is the leading cause of TBIs?
falls
t or f: majority of TBIs result in death
false
What is the term for penetration from the outside resulting in focal damage like a gunshot wound?
open head injury
What is a closed head injury?
- no open wound with damage resulting in diffuse damage to multiple parts of the brain with shearing or tearing

- things that occur after impact
What is the term for the deformation of the brain as it hits inside of the skull that can cause the white matter to stretch , compress & twist?
diffuse axonal injury
What are 4 secondary injuries that can occur in TBI?
- edema
- ischemia
- hemorrhage
- seizures
What is an edema?
when there is swelling in the brain that can result in increased intracranial pressure
When do CTE symptoms usually arise?
- middle age, around 40s
- onset after retirement
- disease gets worse with age
t or f: people with CTE have tau protein just like ppl with AD
true
t or f: CTE doesn’t have amyloid plaques
true
Where does the tau deposition occur in CTE?
- depths of cortical sulci & near blood vessels
Who was the highest concussion rate in football?
- skill positions, aka high-intensity impact players
Who in football has highest risk of CTE?
linemen
