ANSWERS AND EXPLANATIONS

---

A) is associated with infarction of the brainstem

This answer is incorrect.

Diffuse myocardial damage can occur after stroke, without any apparent primary cardiac cause. A study comparing the MRIs of 50 such patients with 50 control patients showed that the right posterior, superior, and medial insula and the right inferior parietal lobule were involved more often in the strokes associated with myocardial damage.  (See References)
