A 58-year-old right-handed man suffers a stroke involving the left posterior inferior frontal gyrus. He speaks in short, effortful phrases with preserved comprehension but impaired repetition. This is characteristic of:

• A Broca's aphasia ✓
• B Global aphasia
• C Wernicke's aphasia
• D Conduction aphasia

Explanation

Broca's (motor/expressive) aphasia results from damage to the posterior inferior frontal gyrus of the dominant hemisphere. Speech is non-fluent and effortful, but comprehension is relatively preserved. Wernicke's aphasia features fluent but meaningless speech with poor comprehension due to posterior superior temporal gyrus damage.
