Fluent speech but nonsensical understanding is typical of which aphasia?

• A. Aphasia
• B. Broca's aphasia
• C. Wernicke's aphasia
• D. Dysarthria

Answer: (C)

Fluent speech with nonsensical understanding is typical of Wernicke's aphasia. In this pattern, speech comes out smoothly and with normal rate and grammar, but comprehension is severely impaired, so what is said often makes little sense and may include wrong or invented words. Patients may not realize their mistakes, and their speech can be filled with semantic errors or jargon, reflecting a disruption in language processing in the left posterior temporal lobe. In contrast, Broca's aphasia presents with nonfluent, effortful speech but relatively preserved comprehension, and dysarthria involves motor speech problems rather than a language comprehension deficit.
