16
Q

Is a focal damage minor?

A

Yes

17
Q

Patient presentation from focal damage to brain?

A

“presents like stroke”
localized or specific deficits

18
Q

Diffuse damage

A

Widespread damage that affects other parts of brain

19
Q

Patient presentation from diffuse damage to brain?

A

“presentation varies”
global deficits
prolonged vegetative state
involves many body systems/structures

20
Q

What happens in a diffuse axonal injury (DAI)?

A

Neural cells in brain are stretched to the point of tear, axons pulled away from cell body

21
Q

What causes a higher risk for dementia associated with DAI?

A

Deposition of tau and APP proteins (plaques and tangles)

22
Q

Most common causes of DAI?

A

Falls
MVA
Assault/Acts of Violence
Suicide attempt
Shaken Baby Syndrome

23
Q

What is a hallmark sign of a DAI (cellular level)?

A

“Retraction ball”
Axon draws back towards cell body

24
Q

Why is it bad to have high levels of calcium from TBI?

A

Calcium cascade leads to apoptosis (cell death!)

25
Q

Complication in axonal regeneration in CNS?

A

More scar tissue build (glial scar formation)
Oligodendrocytes are not as fast and efficient in healing process
Lack of clearance of debris

26
Q

Is axonal regeneration easier or harder in CNS vs PNS?

A

Harder in CNS
Easier in PNS

27
Q

What are the three components to Glasgow Coma Scale?

A

Eye Opening
Verbal Response
Motor Response

28
Q

How are mild TBI objectively diagnosed?

A

Acute Concussion Evaluation (ACE)
Sport Concussion Assessment Tool 5 (SCAT 5)

29
Q

What is Ranchos Los Amigos used for?

A

To assess how much assistance the individual will need to function on a daily basis (general assessment)
