Question 1

Which of the following best describes the difference between acquired brain injury (ABI) and neurodegenerative disease?

Accepted Answer

ABI refers to sudden, focal or acute events causing localized damage, while neurodegenerative diseases involve gradual, progressive decline of neural tissue.

Question 2

A patient presents with sudden paralysis and speech problems. CT scan reveals a blockage in the middle cerebral artery (MCA). Which symptom is most likely to occur?

Accepted Answer

Aphasia and weakness of the face/arm (if left side affected)

Question 3

Which equation best represents the relationship between cerebral blood flow ($$CBF$$), cerebral perfusion pressure ($$CPP$$), and cerebrovascular resistance ($$CVR$$)?

Accepted Answer

$$CBF = \frac{CPP}{CVR}$$

Question 4

Which of the following is NOT a common cause of non-traumatic brain injury?

Accepted Answer

Motor vehicle accident

Question 5

A transient ischemic attack (TIA) is best described as:

Accepted Answer

A short-term, reversible blockage of blood flow to the brain, with symptoms resolving within 24 hours

Question 6

Which artery supplies the medial frontal and parietal lobes of the brain?

Accepted Answer

Anterior cerebral artery (ACA)

Question 7

A hemorrhagic stroke is most commonly caused by which of the following?

Accepted Answer

Chronic hypertension

Question 8

Which of the following best explains why the Circle of Willis is important for cerebral blood flow?

Accepted Answer

It is a circular network that ensures constant blood flow even if one artery is blocked.

Question 9

Which neuropsychological deficit is most likely after a stroke affecting the left hemisphere's middle cerebral artery?

Accepted Answer

Aphasia (language impairment)

Question 10

Which of the following statements about CT scans is TRUE?

Accepted Answer

CT scans are the first imaging tool used in emergency situations to detect stroke and trauma.

Question 11

A patient suffers a subarachnoid hemorrhage. Which space is affected?

Accepted Answer

Between the arachnoid mater and pia mater

Question 12

Which of the following is a key difference between thrombotic and embolic ischemic strokes?

Accepted Answer

Thrombotic strokes are caused by clots that develop in the brain's blood vessels, while embolic strokes are caused by clots that travel from elsewhere in the body.

Question 13

Which of the following arteries supplies the occipital lobe and inferior temporal regions?

Accepted Answer

Posterior cerebral artery (PCA)

Question 14

Which symptom is most likely if the anterior cerebral artery (ACA) is blocked?

Accepted Answer

Contralateral weakness (especially leg), personality or executive changes

Question 15

Which of the following best describes the role of neuropsychology in brain injury rehabilitation?

Accepted Answer

Neuropsychologists study patterns to localize brain function and design rehabilitation plans.

Question 16

Which of the following is a common neuropsychological deficit after stroke?

Accepted Answer

Impairments in speech, memory, reasoning, or emotional regulation depending on the region affected

Question 17

Which of the following is TRUE regarding the treatment window for ischemic stroke with tissue plasminogen activator (tPA)?

Accepted Answer

tPA is most effective if given within 4.5 hours after symptoms begin.

Question 18

Which of the following best describes an aneurysm?

Accepted Answer

A weakened area in the wall of a blood vessel that can bulge or balloon out

Question 19

Which of the following is a key consequence of a hemorrhagic stroke?

Accepted Answer

Pressure on nearby tissue and reduced blood flow beyond the hemorrhage

Question 20

Which of the following is the most common type of stroke?

Accepted Answer

Ischemic stroke
