Q

T/F.

No two TBIs are the same.

A

True

DTI shows that for both brain scans, white matter organization and fibers are much less dense a year later. But outcome looks different between both patients.

  • Patient A looks fuller at a year than it did 2-days post TBI
  • Patient B looks fuller at 2 days, then gets worse

Q

Per year, there are approximately ————- ER vistis, hospitalizations, and deaths each year. Why is this likely an underestimate of the real number of TBIs?

A

2.5 million

because many people are unaware that they have a TBI; also some people don’t have as good of access to care and are unable to go to the hospital/get treated for TBI (e.g., at-risk populations like people experiencing domestic violence)

severe: major damage to the brain, 24+ hours unconscious

TB severity is difficult to determine.

30
Q

What scale is often used to assess the severity of a TBI?

A

Glasgow Coma Scale

The more responsive you are, the more likely your injury is mild.

31
Q

The 3 primary domains assessed in the Glasgow Coma Scale are?

A
  • eye opening
  • verbal response
  • motor response
32
Q

How is the eye opening response measured in the Glasgow Coma Scale?

A

From 1 (severe) to 4 (mild)

eyes open…

  1. no eye opening response
  2. only in response to pressure/pain
  3. only in response to sound
  4. spontaneously
33
Q

How is the verbal response measured in the Glasgow Coma Scale?

A

1 (severe) to 5 (mild)
verbal response is…
1. no verbal response
2. make sounds
3. can say words
4. can speak but is confused
5. orientated

34
Q

How is the motor response measured in the Glasgow Coma Scale?

A

1 (severe) to 6 (mild)

motor response is…
1. no motor response
2. abnormal extension
3. abnormal flexion
4. will flex to withdraw from pain
5. moves in response to localized pain
6. obey commands

35
Q

T/F

You must lose consciousness in order to have a TBI.

A

False, you do not need to lose consciousness to have a mild TBI.

36
Q

Posttraumatic amnesia in TBI says what about the injury severity?

A

the less you are able to remember, the more severe the injury

37
Q

T/F

TBIs are visible on imaging scans.

A

False

Some are, but mild TBIs might not show up on an imaging scan. If it shows up it is probably more severe

38
Q

List 7 physical symptoms of TBI.

A
  • neck pain, headache, numbness
  • imbalance, clumsiness, dizziness
  • sensitivity to noise/light
  • nausea
  • fatigue
  • difficulty with sleep
  • visual impairments (including eye tracking)
39
Q

Explain how TBI might affect your cognitive functions.

A

TBI might have effect on:
- attention, including sustained attention
- memory: especially short-term and learning new info
- executive function: ability to complete goal-oriented behaviors
- processing speed: might know info, but takes longer to pick it from brain

40
Q

What aspects of executive function might be affected by TBI?

A
  • initiation/organization of activity
  • reasoning and problem solving
  • mental flexibility (shifting, multi-tasking)

EF deficits often mistaken for laziness; invisible

41
Q

People who experience a TBI might have communication difficulties including difficulty with:

A
  • rules/cues (both verbal and nonverbal) of social interactions
  • understanding what is being said
  • expressing themselves
42
Q

What symptoms might impact a person with TBI’s ability to understand speech and express themselves?

A

difficult understanding what is being said because of:
- slowed processing speed
- inattention
- difficulty “tracking” conversation

difficulties expressing selves because:
- word-finding difficulties
- poor organization of speech/thought
- struggle to stay on topic

43
Q

Name examples of communications difficulties related to a person with TBI’s issues with:
- rules/cues
- difficulty understanding
- difficulty expressing selves

A

Difficulty with rules/cues:
- might get too close to you (nonverbal)
- inability re “read between the lines” (verbal)

Difficulty w understanding:
- might be inattentive or distractable

Difficulty w expression:
- awkward pauses when preparing to respond
- feeling like they are being “put on the spot”

44
Q

List some emotional/behavioral symptoms a person with TBI might experience.

A
  • personality change
  • difficulty w emotional and behavioral self-regulation (motivation and control)
  • may appear emotionally “flat”
  • may be impulsive/disinhibited (speak without thinking)
  • lack of insight/self-awareness (lack of knowledge about their own emotional state; can’t identify which emotion they are feeling; person who was previously successful might not have cognitive capacity to keep doing job but they don’t realize it)
45
Q

Mental health is a ———– and ———– issue in TBI.

A
  • prevalent
  • persistent

People with TBI are 2.8x more likely to develop psychiatric disorder

46
Q

The consequences of poor mental health are severe for survivors of TBI. Explain.

A

People with TBI are…
- at high risk for suicidal ideation and tendencies after TBI
- make more frequent attempts than those without TBI
- at higher risk of dying by suicide

47
Q

What are the rates of psychiatric disorder so much higher in TBI?

A
  • effects of injury on brain chemistry, structure, functioning
  • psychological impact of accident/event
  • psychosocial effects of resulting diabilities
  • psychiatric disorders also might be pre-disposing risk factor for TBI
48
Q

How many people with TBI have a history of psychiatric disorder before their injury?

A

51%

49
Q

Why is it so important to recognize a TBI in an individual in order to improve mental health.

A
  • having a TBI may complicate treatment efforts for psychiatric disorders
  • “traditional” pscyh interventions may need additional considerations
50
Q

How do the effects of TBI impact brain chemistry, structure, and functioning?

A

limbic system affected = effect on emotional regulation

frontal lobes particularly susceptible to TBI and can affect social function

skull structures that are pointy/hold brain in place can shear the brain as it shakes within skull

51
Q

What traditional psych interventions may need additional consideration when a TBI is involved? Why?

A
  • psycho-pharmacological (medication considerations
  • psychotherapy (might engage with client differently, client may take longer to do things)
  • psychosocial interventions (group therapy or peer support might be more difficult for someone with TBI)
52
Q

TBI Recovery

Domains may resolve at different rates after TBI. ———– may take longer than other symptoms.

A

Cognition

53
Q

TBI Recovery

How long does it take most mild TBIs to recover?

A

within first 3-4 weeks

moderate, severe, and 10% of mild injuries require more time to recover and may become chronic issues

54
Q

Multiple TBIs have a ——— effect.

A

cumulative

want to avoid multiple injuries, especially in short time span

55
Q

People with mild TBIs bounce back much more quickly than moderate/severe injuries. Best chance of returning to normal.

A

(just a fact)

56
Q

What should you do acutely after mild brain injury?

A
  • plenty of rest and sleep
  • avoid physically or cognitively demanding tasks
  • don’t do too much too fast (gradual return)
  • do not “tough it out”
  • avoid alcohol and other substances
  • repeat concussions before brain has healed can be dangerous (be safe!)
57

A

True

58
Q

T/F

Mental health issues clear up quickly after TBI and are only relevant immediately following the injury.

False

59

True

60
Q

It is okay to resume all normal activities immediately after sustaining a TBI.
