What does right ACA stroke typically impair?

• A. left arm movement
• B. left leg movement
• C. both arms and legs
• D. speech clarity

Answer: (B)

A right ACA (anterior cerebral artery) stroke typically results in impairments on the contralateral side of the body, which in this case is the left side. The anterior cerebral artery mainly supplies blood to the medial frontal lobe and superior medial parietal lobe. This region is responsible for controlling movement and sensation in the lower extremities, particularly the legs. When there is an occlusion or impairment in blood flow from the right ACA, it affects the part of the brain responsible for voluntary movement of the left leg, leading to weakness or loss of movement in that area. This is why the response indicating the impairment of left leg movement following a right ACA stroke is considered accurate. Understanding the blood supply and functional areas of the brain is crucial in interpreting the effects of strokes accurately.
