After sustaining a CVA, what is the most likely location of the lesion in Ms. Williams, given her symptoms?

• A. Left posterior superior temporal gyrus
• B. Left inferior frontal gyrus
• C. Left superior frontal gyrus
• D. Left inferior parietal gyrus

Answer: (A)

The left posterior superior temporal gyrus is a critical area for language comprehension and processing, particularly relevant in the context of a cerebrovascular accident (CVA). Damage to this region can lead to symptoms associated with language deficits, such as difficulties in understanding spoken language (receptive language deficits) and potentially aspects of expressive language depending on the extent of the lesion. In patients who have experienced a CVA, particularly when symptoms align with those of receptive aphasia, the left posterior superior temporal gyrus is often implicated due to its role in the Wernicke’s area of the brain. This area is responsible for the comprehension of language and helps in the processing of auditory information related to language. Therefore, when a CVA occurs in this region, it is likely to manifest in the individual's difficulty with grasping the meaning of words and sentences while being able to produce fluent but nonsensical speech. The other locations mentioned may contribute to various speech and language deficits, but do not specifically align with the symptoms typically seen when the posterior superior temporal gyrus is affected. The left inferior frontal gyrus (Broca’s area) is primarily linked to expressive language and motor speech production. The left superior frontal gyrus is involved in higher cognitive functions and does not
