TBI TBI Cognitive & Behavioral Outcomes 3

Question 1

Chronic Traumatic Encephalopathy (CTE) is a progressive neurodegenerative condition associated with which risk factor?

Accepted Answer

Repetitive head impacts over time (multiple concussions)

Answer

CTE is linked to cumulative repetitive head trauma — particularly in contact sports and military service — rather than a single TBI event.

Question 2

Which population has shown the greatest risk of developing dementia following TBI?

Accepted Answer

Older adults and those with moderate-to-severe TBI, especially with loss of consciousness

Answer

Epidemiological studies show that older adults and those with more severe TBI have significantly elevated lifetime risk of developing dementia.

Question 3

Which standardized neuropsychological assessment battery is commonly used to evaluate cognitive outcomes after TBI?

Accepted Answer

Repeatable Battery for Assessment of Neuropsychological Status (RBANS)

Answer

RBANS assesses immediate/delayed memory, language, visuospatial skills, and attention — domains commonly impaired after TBI.

Question 4

Impaired self-awareness (anosognosia) after TBI is most associated with damage to which brain region?

Accepted Answer

Right prefrontal and parietal cortex

Answer

Anosognosia — lack of awareness of one's deficits — is most associated with right hemisphere and prefrontal cortical damage.

Question 5

Return-to-work outcomes after TBI are most strongly predicted by which factors?

Accepted Answer

Injury severity, cognitive function, pre-injury employment, and psychological adjustment

Answer

Multiple factors including TBI severity, residual cognitive deficits, pre-injury work status, and coping ability together predict return-to-work success.
