A left middle cerebral artery stroke in a typically right-handed person would most likely cause which combination?

• A. Right-sided weakness with aphasia.
• B. Left-sided weakness with neglect.
• C. Right-sided sensory loss only.
• D. Bilateral facial weakness.

Answer: (C)

In a stroke that affects the left middle cerebral artery territory in a person who is typically right‑handed, language functions are usually located in the left hemisphere. The left MCA also supplies the lateral aspects of the frontal and parietal lobes that control movement and sensation for the right side of the body. So damage here commonly produces a combination of right‑sided motor weakness or paralysis and sensory loss, along with aphasia if the language centers are involved. The classic and most likely presentation is right‑sided weakness with aphasia, reflecting both contralateral motor/sensory involvement and disruption of language areas in the dominant hemisphere. A pure sensory loss on the right without motor or language changes is less typical for a dominant left MCA stroke, and left‑sided weakness with neglect points toward a non‑dominant (usually right) hemisphere stroke. Bilateral facial weakness would suggest a broader or different localization beyond a typical unilateral MCA event. So the scenario that best fits a left MCA stroke in a right‑handed person is right‑sided weakness combined with aphasia, though individual presentations can vary depending on the exact extent and location of the infarct.
