NEUROLOGY - STROKE

Question 1

A 62-year-old male presents with sudden-onset right-sided weakness and sensory loss. He has difficulty speaking and understanding language. On examination, there is right-sided facial droop and weakness of the right arm and leg. There is also sensory loss on the right side of the body. The most likely stroke subtype is:
A) TACI
B) LACI
C) POCI
D) PACI

Answer 1

A) TACI

Explanation: The patient’s symptoms include right-sided weakness, sensory loss, and language difficulties, suggesting a large infarction involving the entire territory of the anterior cerebral circulation, which is characteristic of TACI.

Question 2

A 56-year-old female presents with sudden-onset weakness in the left arm and leg. She has no other neurological symptoms. On examination, there is isolated weakness in the left side of the body, without any sensory loss or language difficulties. The most likely stroke subtype is:
A) TACI
B) LACI
C) POCI
D) PACI

Answer 2

B) LACI

Explanation: The patient’s symptoms of isolated weakness on one side of the body without sensory loss or language difficulties are consistent with a small, deep infarct, characteristic of LACI.

Question 3

A 70-year-old male presents with sudden-onset dizziness, double vision, and difficulty coordinating movements. On examination, there is nystagmus, impaired coordination, and bilateral weakness of the face and limbs. The most likely stroke subtype is:
A) TACI
B) LACI
C) POCI
D) PACI

Answer 3

C) POCI

Explanation: The patient’s symptoms of dizziness, double vision, and coordination difficulties, along with bilateral weakness of the face and limbs, suggest an infarction in the posterior circulation, specifically the brainstem. This is characteristic of POCI.

Question 4

A 45-year-old female presents with sudden-onset right-sided weakness and mild difficulty speaking. On examination, there is right-sided facial weakness and mild weakness of the right arm and leg. There is no sensory loss. The most likely stroke subtype is:
A) TACI
B) LACI
C) POCI
D) PACI

Answer 4

D) PACI

Explanation: The patient’s symptoms of right-sided weakness and mild speech difficulty, without sensory loss, suggest a partial infarction of the anterior cerebral circulation. This is characteristic of PACI.

Question 5

A 68-year-old male presents with sudden-onset dizziness, difficulty swallowing, and slurred speech. On examination, there is dysarthria, dysphagia, and impaired coordination. There are no motor or sensory deficits. The most likely stroke subtype is:
A) TACI
B) LACI
C) POCI
D) PACI

Answer 5

C) POCI

Explanation: The patient’s symptoms of dizziness, difficulty swallowing, slurred speech, and impaired coordination suggest an infarction in the posterior circulation, particularly affecting the cerebellum. This is characteristic of POCI.

Question 6

A 50-year-old male presents with sudden-onset right-sided weakness and sensory loss. On examination, there is weakness of the right arm and leg, along with sensory loss on the right side of the body. There are no language difficulties. The most likely stroke subtype is:
A) TACI
B) LACI
C) POCI
D) PACI

Answer 6

B) LACI

Explanation: The patient’s symptoms of right-sided weakness and sensory loss without language difficulties are consistent with a small, deep infarct, characteristic of LACI.

Question 7

A 60-year-old female presents with sudden-onset left-sided weakness and numbness. On examination, there is weakness of the left arm and leg, along with numbness on the left side of the body. She also experiences difficulty with coordination and balance. The most likely stroke subtype is:
A) TACI
B) LACI
C) POCI
D) PACI

Answer 7

D) PACI

Explanation: The patient’s symptoms of left-sided weakness, numbness, and difficulty with coordination and balance suggest a partial infarction of the anterior cerebral circulation, characteristic of PACI.

Question 8

A 72-year-old male presents with sudden-onset severe headache, nausea, and vomiting. On examination, there are no focal neurological deficits. A CT scan reveals subarachnoid hemorrhage. The most likely cause of the patient’s symptoms is:
A) Ischemic stroke
B) Hemorrhagic stroke
C) Transient ischemic attack (TIA)
D) Migraine with aura

Answer 8

B) Hemorrhagic stroke

Explanation: The sudden-onset severe headache, nausea, vomiting, and presence of subarachnoid hemorrhage on CT scan indicate a hemorrhagic stroke, which is characterized by bleeding in the brain.

Question 9

A 55-year-old male presents with sudden-onset vertigo, nausea, and difficulty walking. On examination, there is horizontal nystagmus, impaired coordination, and unsteady gait. The most likely stroke subtype is:
A) TACI
B) LACI
C) POCI
D) PACI

Answer 9

C) POCI

Explanation: The patient’s symptoms of vertigo, impaired coordination, unsteady gait, and horizontal nystagmus suggest an infarction in the posterior circulation, particularly affecting the cerebellum. This is characteristic of POCI.

Question 10

A 65-year-old female presents with sudden-onset left-sided weakness and numbness. On examination, there is weakness of the left arm and leg, along with numbness on the left side of the body. She also experiences difficulty speaking and understanding language. The most likely stroke subtype is:
A) TACI
B) LACI
C) POCI
D) PACI

Answer 10

A) TACI

Explanation: The patient’s symptoms of left-sided weakness, numbness, and language difficulties suggest a large infarction involving the entire territory of the anterior cerebral circulation, characteristic of TACI.
