Fluent Aphasia with preserved comprehension and impaired repetition is
**Core Concept**
Fluent Aphasia, also known as Wernicke's Aphasia, is a type of aphasia characterized by difficulties with language comprehension and production, despite the presence of fluent speech. This condition is often associated with damage to the posterior superior temporal gyrus (Wernicke's area) in the left hemisphere of the brain. The preservation of comprehension and impaired repetition in Fluent Aphasia is a distinctive clinical feature.
**Why the Correct Answer is Right**
In Fluent Aphasia, patients often exhibit a remarkable ability to produce long, grammatically correct sentences, but with little to no semantic meaning. This is due to the disconnection between Wernicke's area, responsible for language comprehension, and Broca's area, responsible for language production. As a result, patients may repeat words or phrases without understanding their meaning, a phenomenon known as "parrot-like" repetition. The preservation of comprehension is thought to be due to the relatively intact left posterior inferior temporal gyrus, which is involved in semantic processing.
**Why Each Wrong Option is Incorrect**
**Option A:** This option is incorrect because Fluent Aphasia is characterized by impaired comprehension, not preserved comprehension.
**Option B:** This option is incorrect because Anomic Aphasia is a type of aphasia characterized by difficulties with naming objects and people, not fluent speech with impaired repetition.
**Option C:** This option is incorrect because Broca's Aphasia is a type of aphasia characterized by non-fluent speech and preserved comprehension, not fluent speech with impaired repetition.
**Clinical Pearl / High-Yield Fact**
Fluent Aphasia is often associated with agrammatism, which is the use of grammatically correct sentences with little to no semantic meaning. This can be remembered using the mnemonic "Wernicke's Area: Words without Meaning".
**Correct Answer:** D. Fluent Aphasia with preserved comprehension and impaired repetition is a characteristic of Wernicke's Aphasia.
