Adults over 65
Infants under 12 months
Preschool children ages 3-5
School-age children and adolescents (Correct answer)

Correct answer: School-age children and adolescents

'Growing into deficit' describes school-age and adolescent TBI survivors who appear recovered early but show increasing deficits as developmental demands outpace their injured brain's capacity.

Question 2: Which professional setting most commonly employs CBIS-credentialed specialists outside of acute hospital care?

Urgent care centers
Primary care physician offices
Dental clinics
Long-term acute care and rehabilitation facilities (Correct answer)

Correct answer: Long-term acute care and rehabilitation facilities

Long-term acute care and inpatient rehabilitation facilities are among the most common employers of brain injury specialists beyond the acute hospital phase.

Question 3: What is cerebral autoregulation?

The brain's ability to generate new neurons after injury
The automatic adjustment of cerebral blood flow to maintain stable perfusion despite changes in systemic blood pressure (Correct answer)
The control of CSF production by the choroid plexus
The regulation of neurotransmitter reuptake at synapses

Correct answer: The automatic adjustment of cerebral blood flow to maintain stable perfusion despite changes in systemic blood pressure

Cerebral autoregulation is the mechanism by which cerebral blood vessels dilate or constrict to maintain relatively constant cerebral blood flow across a range of systemic blood pressures.

Question 4: Which behavioral rating scale is specifically designed to assess neurobehavioral symptoms commonly seen after TBI as reported by both clients and their significant others?

Behavior Rating Inventory of Executive Function (BRIEF)
Hamilton Anxiety Rating Scale (HARS)
Neurobehavioral Functioning Inventory (NFI) (Correct answer)
Beck Depression Inventory-II (BDI-II)

Correct answer: Neurobehavioral Functioning Inventory (NFI)

The NFI gathers self- and proxy-report data on depression, somatic complaints, memory, communication, aggression, and motor symptoms after TBI.

Question 5: The HELPS Brain Injury Screening Tool is used by brain injury specialists primarily to:

Determine readiness for vocational rehabilitation
Guide pharmacological management decisions
Screen for unidentified prior TBI in adults presenting with complex needs (Correct answer)
Assess current cognitive functioning in post-acute patients

Correct answer: Screen for unidentified prior TBI in adults presenting with complex needs

HELPS (Head injury, Employed before injury, Learning disability, Physical disability, Substance abuse) identifies undetected TBI history in populations with multiple vulnerabilities.

Question 6: A CBIS-certified occupational therapist transitions to a Veterans Affairs (VA) facility. How does the credential serve in this context?

It demonstrates TBI specialty knowledge highly relevant to the VA's large brain-injured veteran population (Correct answer)
It limits the therapist to civilian patient care only
It replaces the requirement for OT licensure in the VA system
It is not recognized within federal healthcare systems

Correct answer: It demonstrates TBI specialty knowledge highly relevant to the VA's large brain-injured veteran population

The VA serves a large population of veterans with TBI, making CBIS certification directly relevant and highly valued in VA employment contexts.

Question 7: When a TBI survivor with impulsivity consistently blurts out other members' confidential information, the facilitator should:

Ignore minor breaches to avoid stigmatizing impulsivity
Address confidentiality in the group, privately coach the member on impulse strategies, and consider individual sessions to supplement group work (Correct answer)
Ask other members to self-censor to protect against future breaches
Expel the member immediately

Correct answer: Address confidentiality in the group, privately coach the member on impulse strategies, and consider individual sessions to supplement group work

Addressing confidentiality at the group level and coaching the individual balances group safety with neurologically-informed support for impulsivity.

The BIAA is the leading national advocacy organization that provides educational resources, a national helpline, state affiliate connections, and support network access for brain injury survivors and their families.

Question 9: Which ethical principle is most relevant when a TBI survivor in crisis refuses a recommended safety intervention?

Beneficence always overrides autonomy in TBI populations
Staff preference determines the intervention when the survivor is unable to comply
Legal guardianship automatically removes all patient rights during crisis
Balancing respect for autonomy with duty to prevent harm requires individualized clinical judgment (Correct answer)

Correct answer: Balancing respect for autonomy with duty to prevent harm requires individualized clinical judgment

Ethical crisis intervention requires individualized judgment that weighs the survivor's autonomy against the professional duty to prevent harm.

Question 10: A CBIS specialist earned CE hours in a prior recertification cycle that exceeded the 20-hour minimum. Can these surplus hours be carried forward to the next cycle?

Yes, unlimited carry-forward is permitted
Yes, but only hours from ACBIS-hosted events
Yes, up to 10 hours may be carried forward
No, CE hours cannot be carried over to the next cycle (Correct answer)

Correct answer: No, CE hours cannot be carried over to the next cycle

CBIS recertification CE hours generally cannot be carried forward; each cycle requires independently meeting the minimum hour requirement.

Question 11: What does the term 'invisible disability' mean in the context of brain injury, and why is it important for family education?

Cognitive, emotional, and behavioral deficits that are not visually apparent but significantly impair functioning (Correct answer)
A disability that only affects internal organs with no outward signs
A legal classification for insurance reimbursement purposes
A disability that only manifests during sleep

Correct answer: Cognitive, emotional, and behavioral deficits that are not visually apparent but significantly impair functioning

Brain injury often produces cognitive, emotional, and behavioral changes that are not visible to others, which can lead to misunderstanding, reduced support, and social isolation for survivors.

Question 12: What does the Disability Rating Scale (DRS) primarily measure in brain injury rehabilitation?

Pain intensity and frequency
Overall level of disability from coma to community reintegration (Correct answer)
Neuroimaging findings correlated with behavior
Cognitive processing speed only

Correct answer: Overall level of disability from coma to community reintegration

The DRS tracks the full spectrum of recovery from coma through return to productive activity in the community.

Question 13: In a randomized controlled trial (RCT) studying TBI rehabilitation, what is the PRIMARY purpose of the control group?

To receive a placebo intervention
To reduce the overall sample size needed
To provide a comparison baseline against which treatment effects are measured (Correct answer)
To allow researchers to test multiple interventions simultaneously

Correct answer: To provide a comparison baseline against which treatment effects are measured

The control group provides a baseline comparison so researchers can attribute observed changes to the treatment rather than natural recovery or other factors.

Question 14: When a TBI patient's cultural norm involves avoiding direct eye contact with authority figures, a clinician should:

Interpret avoidance of eye contact as a sign of confusion or decreased arousal
Encourage the patient to maintain eye contact as part of social skills training
Recognize it as a culturally normative behavior and not pathologize it (Correct answer)
Note it as a potential neurological symptom in the chart

Correct answer: Recognize it as a culturally normative behavior and not pathologize it

Eye contact norms vary widely across cultures, and misinterpreting cultural behavior as a neurological symptom can lead to diagnostic errors.

Question 15: Which scenario BEST demonstrates intersectionality as relevant to TBI care?

A patient who speaks two languages and receives bilingual therapy
A patient who has both a TBI and a spinal cord injury
A TBI survivor who belongs to both a veterans' group and a disability advocacy organization
A Latina woman who is also low-income and uninsured, facing compounded barriers to TBI rehabilitation (Correct answer)

Correct answer: A Latina woman who is also low-income and uninsured, facing compounded barriers to TBI rehabilitation

Intersectionality recognizes that overlapping identities (race, gender, class) create compounded and unique experiences of disadvantage in healthcare.

Question 16: Which neurodevelopmental concept explains why adolescent TBI survivors are at heightened risk for impulsive decision-making compared to adults with equivalent injuries?

Limbic-prefrontal imbalance due to incomplete myelination (Correct answer)
Lower baseline cortisol in teens
Synaptic pruning completion in adolescence
Greater hippocampal neurogenesis in adults

Correct answer: Limbic-prefrontal imbalance due to incomplete myelination

The adolescent brain has a mature, reactive limbic system but an incompletely myelinated prefrontal cortex, creating a regulatory imbalance that TBI worsens.

Question 17: What is the primary goal of vocational rehabilitation services for TBI survivors in the US?

Certifying individuals as permanently unable to work
Helping individuals with TBI return to gainful employment consistent with their abilities and interests (Correct answer)
Providing lifetime attendant care in the home
Permanent disability income through SSDI benefits

Correct answer: Helping individuals with TBI return to gainful employment consistent with their abilities and interests

Vocational rehabilitation aims to maximize employment potential by providing assessment, training, job placement, and support services tailored to the TBI survivor's residual abilities.

Question 18: What is the format of the CBIS exam?

Practical skills demonstration
Oral examination
Essay-based questions
Multiple-choice questions (Correct answer)

Correct answer: Multiple-choice questions

This format efficiently assesses a broad range of knowledge across various topics related to brain injury care. It allows for objective scoring and ensures consistent evaluation of candidates' understanding of the core curriculum.

Question 19: During TBI assessment, a positive Babinski sign (upgoing plantar reflex) indicates:

Upper motor neuron pathology (Correct answer)
Brainstem herniation
Cerebellar dysfunction
Peripheral nerve damage

Correct answer: Upper motor neuron pathology

An upgoing big toe in response to plantar stimulation (positive Babinski) is a sign of upper motor neuron dysfunction such as corticospinal tract injury.

Question 20: When treating post-traumatic depression in a TBI patient, SSRIs are preferred over tricyclic antidepressants primarily because TCAs:

Cause irreversible dopamine depletion
Have anticholinergic effects that worsen cognition and lower seizure threshold (Correct answer)
Are less effective for depressive symptoms
Cannot cross the blood-brain barrier after TBI

Correct answer: Have anticholinergic effects that worsen cognition and lower seizure threshold

TCAs have significant anticholinergic side effects that impair cognition and increase seizure risk, making SSRIs the safer first-line choice in TBI.

Question 21: During verbal de-escalation, which staff behavior is most likely to escalate rather than calm a TBI survivor in crisis?

Allowing silence and processing time
Standing at eye level with the individual
Crossing arms and using a commanding tone (Correct answer)
Maintaining a neutral facial expression

Correct answer: Crossing arms and using a commanding tone

Crossed arms and a commanding tone are perceived as threatening and authoritarian, which increases defensive aggression in distressed individuals.

Question 22: Why might ACBIS periodically update the content domains covered in CBIS continuing education requirements?

A late fee only, with no credential impact
A 30-day grace period with no penalty
Immediate permanent revocation
Automatic suspension of the credential (Correct answer)

Correct answer: Automatic suspension of the credential

Failure to meet recertification deadlines results in automatic suspension of the CBIS credential until requirements are fulfilled.

Question 24: How does post-TBI fatigue most significantly affect community reintegration?

It primarily causes physical weakness that limits mobility
It is only a side effect of TBI medications and resolves when drugs are changed
It limits the stamina for sustained activity, social participation, and work, often requiring activity pacing and environmental modifications (Correct answer)
It exclusively affects sleep at night without impacting daytime functioning

Correct answer: It limits the stamina for sustained activity, social participation, and work, often requiring activity pacing and environmental modifications

TBI-related fatigue is multidimensional (physical, cognitive, emotional) and is one of the most common barriers to returning to work and community roles, requiring pacing strategies and structured rest periods.

Question 25: According to resilience research, which factor is the strongest protective influence on long-term psychosocial outcomes after childhood TBI?

Consistent, warm family support and low family stress (Correct answer)
Male gender
High pre-injury IQ
Rural residence reducing social demands

Correct answer: Consistent, warm family support and low family stress

Family cohesion, warmth, and low stress consistently emerge as the strongest protective factors for psychosocial recovery after pediatric TBI.

Question 26: Which statement accurately reflects the global reach of the CBIS credential?

ACBIS actively promotes the CBIS internationally and some holders practice outside the US (Correct answer)
The CBIS is a European credential recently adopted by the US
International holders must re-examine annually due to differing brain injury laws
The CBIS is recognized exclusively in the United States and has no international presence

Correct answer: ACBIS actively promotes the CBIS internationally and some holders practice outside the US

While rooted in the US, ACBIS has extended its credentialing internationally, and professionals in other countries have earned the CBIS designation.

Question 27: What role does the CBIS credential play in advocacy for individuals with brain injuries?

It legally empowers holders to file insurance appeals on behalf of patients
It grants credential holders voting rights on state brain injury policy boards
It qualifies holders to testify as expert witnesses in TBI litigation
It demonstrates a trained, knowledgeable workforce committed to quality care (Correct answer)

Correct answer: It demonstrates a trained, knowledgeable workforce committed to quality care

A credentialed brain injury workforce demonstrates commitment to quality, which strengthens advocacy efforts for improved services and funding.

Question 28: A CBIS professional observes that a patient's behavior changes significantly depending on the environment and the assessor. This variability is MOST likely attributable to:

Poor test-taking motivation
Neurological inconsistency consistent with TBI-related fatigue and context sensitivity (Correct answer)
Fabrication of symptoms
Borderline personality disorder

Correct answer: Neurological inconsistency consistent with TBI-related fatigue and context sensitivity

TBI patients commonly show performance variability due to fatigue, overstimulation, and context sensitivity, which reflects genuine neurological dysfunction.

Question 29: Which aspect of Vygotsky's theory is most applicable when designing rehabilitation tasks for a TBI survivor with executive function deficits?

Formal operational thinking
Zone of Proximal Development (Correct answer)

Question 31: Hyperbaric oxygen therapy (HBOT) for TBI is currently considered:

Contraindicated due to increased ICP risk
Experimental with insufficient evidence to recommend routinely (Correct answer)
Standard of care for moderate TBI
First-line treatment for post-concussion syndrome

Correct answer: Experimental with insufficient evidence to recommend routinely

Current evidence does not support HBOT as a routine TBI treatment; clinical trials have shown mixed results and it remains investigational.

Question 32: Which legal document is most important for families to understand when a brain injury survivor cannot make independent decisions?

A no-contact order issued by a court
A durable power of attorney or guardianship document authorizing decision-making (Correct answer)
A standard employment contract
A living will for end-of-life preferences only

Correct answer: A durable power of attorney or guardianship document authorizing decision-making

A durable power of attorney or guardianship designation legally authorizes a family member to make medical, financial, or personal decisions on behalf of an incapacitated brain injury survivor.

Occipital lobe at the impact site
Cerebellum
Frontal and temporal poles at the contrecoup site (Correct answer)
Parietal lobes bilaterally

Correct answer: Frontal and temporal poles at the contrecoup site

A blow to the occiput commonly produces contrecoup damage to the frontal and temporal poles, which are particularly vulnerable due to irregular skull surfaces.

Question 44: Which cranial nerve is most commonly injured in basilar skull fractures involving the anterior fossa, leading to anosmia?

Cranial nerve II (optic)
Cranial nerve III (oculomotor)
Cranial nerve I (olfactory) (Correct answer)
Cranial nerve VII (facial)

Correct answer: Cranial nerve I (olfactory)

Barthel Index
Montreal Cognitive Assessment (MoCA)

Correct answer: Awareness Questionnaire (AQ)

The Awareness Questionnaire (AQ) compares patient self-ratings to clinician and significant-other ratings to quantify unawareness of deficits.

Question 47: A CBIS practitioner is assessing a patient for hemispatial neglect. Which bedside test is most commonly used?

Digit Span test
Wisconsin Card Sorting Test
Line bisection and cancellation tasks (Correct answer)
Trail Making Test

Correct answer: Line bisection and cancellation tasks

Line bisection and cancellation tasks are standard bedside assessments for hemispatial neglect, revealing inattention to one side of space.

Question 48: A CBIS specialist observes that a survivor's challenging behavior escalates when family members are present. This pattern is most likely explained by:

Worsening neurological status
Organic disinhibition independent of social context
Conditioned emotional responses tied to family attachment dynamics (Correct answer)
Medication non-compliance

Correct answer: Conditioned emotional responses tied to family attachment dynamics

Attachment-based conditioned emotional responses can cause behavior to escalate specifically with emotionally significant others, reflecting learned relational patterns.

Question 49: Which developmental milestone is considered a prerequisite for effective use of compensatory memory strategies in TBI rehabilitation?

Centration
Conservation
Object permanence
Metacognition (Correct answer)

Correct answer: Metacognition

Metacognition—awareness of one's own cognitive processes—is necessary for a survivor to recognize memory deficits and consistently apply compensatory strategies.

Question 50: When a TBI survivor struggles to understand sarcasm and nonliteral language, this deficit is best categorized as impairment in:

Theory of Mind (Correct answer)
Procedural memory
Semantic memory
Phonological processing

Correct answer: Theory of Mind

Theory of Mind enables understanding of others' mental states and nonliteral communication; TBI commonly disrupts this social-cognitive ability.

Question 51: According to attachment theory, a TBI survivor who becomes excessively clingy and fears abandonment during recovery most likely had which premorbid attachment style?

Anxious-preoccupied attachment (Correct answer)
Secure attachment
Disorganized attachment
Avoidant attachment

Correct answer: Anxious-preoccupied attachment

Anxious-preoccupied attachment involves fear of abandonment and excessive dependence on others, which TBI-related vulnerability can intensify.

Question 52: Which of the following is the PRIMARY purpose of the Comprehensive Trail Making Test (CTMT) in TBI assessment?

Screening for major depression
Measuring visual acuity
Evaluating executive function, attention, and processing speed (Correct answer)
Assessing language fluency

Correct answer: Evaluating executive function, attention, and processing speed

The CTMT assesses executive function, visual search, mental flexibility, and processing speed by requiring patients to connect numbered or mixed sequences.

Question 53: A TBI survivor raised in a collectivist culture places family decision-making above personal autonomy in rehabilitation choices. A CBIS specialist should:

Document it as psychosocial dependence
Override family influence to promote patient independence
Refer to psychiatry for autonomy deficits
Recognize this as a cultural value and incorporate family into shared decision-making (Correct answer)

Correct answer: Recognize this as a cultural value and incorporate family into shared decision-making

Cultural competence requires recognizing that collectivist values are normative for many cultures, and rehabilitation should accommodate family-centered decision-making.

Question 54: A patient sustains a TBI and develops unequal pupils (anisocoria) with one pupil dilated and non-reactive. This is most concerning for:

Transtentorial (uncal) herniation compressing CN III (Correct answer)
Subdural hygroma
Diffuse axonal injury
Pontine hemorrhage

Correct answer: Transtentorial (uncal) herniation compressing CN III

A fixed dilated pupil following TBI typically indicates uncal herniation compressing the ipsilateral oculomotor nerve (CN III).

Question 55: How can families best support neuroplasticity and cognitive recovery in a brain injury survivor at home?

Providing consistent, repetitive practice of functional tasks within a structured routine (Correct answer)
Avoiding all cognitive challenges to prevent frustration
Allowing the survivor to set entirely unstructured daily schedules
Encouraging complete bed rest and minimal stimulation indefinitely

Correct answer: Providing consistent, repetitive practice of functional tasks within a structured routine

Consistent, repetitive practice of meaningful functional tasks harnesses neuroplasticity by reinforcing neural pathways, while structured routines reduce cognitive fatigue and build independence.

Question 56: What is neuroplasticity in the context of TBI rehabilitation?

Pharmacological enhancement of neurotransmitter activity post-injury
The brain's susceptibility to repeated injury after an initial TBI
The brain's ability to reorganize neural connections and compensate for damaged areas through experience and therapy (Correct answer)
The inflammatory response of glial cells following brain trauma

Correct answer: The brain's ability to reorganize neural connections and compensate for damaged areas through experience and therapy

Neuroplasticity refers to the brain's capacity to form new synaptic connections and reorganize existing pathways, which is the neurological foundation for functional recovery through rehabilitation.

Question 57: A TBI survivor with intact motor function but poor task planning would most benefit from which occupational therapy approach?

Proprioceptive neuromuscular facilitation (PNF)
Kinesio taping
Neurodevelopmental treatment (NDT)
Dynamic Interactional Model (DIM) (Correct answer)

Correct answer: Dynamic Interactional Model (DIM)

The Dynamic Interactional Model addresses cognitive processing strategies during functional tasks, making it ideal for planning and organizational deficits.

Question 58: What is the recommended resource for preparing for the CBIS exam?

Relying on the official study guide maximizes preparation effectiveness and increases the likelihood of success.

Question 59: Post-TBI behavioral disinhibition in a 30-year-old male most likely reflects injury to which brain region involved in adult behavioral regulation?

Prefrontal cortex (Correct answer)
Primary somatosensory cortex
Occipital lobe
Cerebellum

Correct answer: Prefrontal cortex

The prefrontal cortex governs impulse control, social judgment, and behavioral inhibition, and is frequently damaged in TBI causing disinhibition.

Question 60: The Orientation Log (O-Log) is primarily used to monitor which phase of TBI recovery?

Post-traumatic amnesia (PTA) resolution (Correct answer)
Vocational readiness
Long-term community reintegration
Chronic pain management

Correct answer: Post-traumatic amnesia (PTA) resolution

The O-Log is a brief daily measure of orientation used to track emergence from post-traumatic amnesia during inpatient rehabilitation.

Question 61: A CBIS specialist administers the Disability Rating Scale (DRS). Which domain is NOT assessed by the DRS?

Cognitive ability for self-care
Level of functioning
Arousability
Language function (Correct answer)

Correct answer: Language function

The DRS measures arousability, cognitive ability for self-care, dependability level of functioning, and employability—not language function specifically.

Question 62: Which self-care strategy is most important to recommend to family caregivers of brain injury survivors?

Maintaining personal health, social connections, and using available support systems (Correct answer)
Avoiding communication with the rehabilitation team to remain independent
Sacrificing all personal needs to maximize time spent caregiving
Discontinuing all personal activities until the survivor is fully independent

Correct answer: Maintaining personal health, social connections, and using available support systems

Caregivers who maintain their own health, relationships, and support networks sustain caregiving capacity longer and experience less burnout, ultimately benefiting the survivor as well.

Question 63: A CBIS specialist notes that a client's scores on attention tasks decline sharply in noisy environments compared to quiet settings. This finding most likely reflects:

Improvement in baseline cognitive function
A medication side effect unrelated to brain injury
Reduced cognitive reserve under environmental demand (Correct answer)
Malingering or symptom exaggeration

Correct answer: Reduced cognitive reserve under environmental demand

Increased environmental demands expose limitations in cognitive reserve common after TBI, particularly in attention and processing speed.

Question 64: What is the primary purpose of the CBIS certification program?

To validate professional competence and knowledge in the field (Correct answer)
To limit the number of professionals
To replace academic degrees
To generate revenue for the certifying organization

Correct answer: To validate professional competence and knowledge in the field

The CBIS certification validates that professionals have demonstrated the knowledge and skills required for competent practice.

Question 65: Which environmental modification best supports crisis prevention in a TBI rehabilitation setting?

Using fluorescent lighting to maintain circadian rhythm
Scheduling all therapy in the afternoon when staff is most available
Increasing ambient noise to stimulate alertness
Reducing visual clutter and overstimulation (Correct answer)

Correct answer: Reducing visual clutter and overstimulation

Reducing sensory overstimulation decreases the likelihood of behavioral dysregulation in TBI survivors.

Question 66: What does 'independent living' mean in TBI rehabilitation, and which federal program supports it?

Living alone without any disability-related services
Living in the community with self-determined supports; promoted through the Independent Living Program under the Rehabilitation Act (Correct answer)
Residing in an assisted living facility without family involvement
Returning to pre-injury employment without accommodations

Correct answer: Living in the community with self-determined supports; promoted through the Independent Living Program under the Rehabilitation Act

Independent living emphasizes consumer control and self-determination in managing one's life in the community, supported by Centers for Independent Living (CILs) funded under Title VII of the Rehabilitation Act.

Question 67: Post-traumatic amnesia (PTA) duration is most strongly predictive of which outcome variable?

Likelihood of seizure development
Long-term functional and vocational outcome (Correct answer)
Rate of motor recovery in rehabilitation
Mortality risk in the acute phase

Correct answer: Long-term functional and vocational outcome

PTA duration is one of the strongest predictors of long-term functional outcome, including return to work and independent living.

Question 68: Which factor most significantly limits the generalizability of skills learned during TBI rehabilitation to real-world settings?

Transfer-appropriate processing failure (context dependency) (Correct answer)
Inadequate caregiver training
Premorbid low IQ
Insufficient session frequency

Correct answer: Transfer-appropriate processing failure (context dependency)

Skills are most easily retrieved in the context in which they were learned; training in clinical settings may not transfer to community environments without deliberate generalization strategies.

Question 69: A patient exhibits difficulty recognizing familiar faces despite intact visual acuity. This presentation is most consistent with damage to which brain region?

Left hemisphere Broca's area
Primary visual cortex in the occipital lobe
Right fusiform face area in the temporal lobe (Correct answer)
Anterior cingulate cortex

Correct answer: Right fusiform face area in the temporal lobe

Prosopagnosia (inability to recognize faces) is associated with bilateral or right fusiform gyrus damage in the temporal lobe.

Question 70: A patient with TBI demonstrates intact recall of events before the injury but cannot form new memories. This pattern is classified as:

Transient global amnesia
Retrograde amnesia only
Both retrograde and anterograde amnesia
Anterograde amnesia only (Correct answer)

Correct answer: Anterograde amnesia only

Anterograde amnesia is the inability to form new memories after the injury, while pre-injury memories remain intact.
