Which aphasia is characterized by fluent speech with severely impaired comprehension and naming?

Fluent speech with severely impaired comprehension and naming points to Wernicke's aphasia. In this type, speech flows smoothly and grammatically, but the content is often meaningless or filled with paraphasias, and understanding spoken language is severely compromised. Naming ability is also poor, and patients may be unaware of their deficits. Repetition is typically impaired as well because the underlying language comprehension is disrupted. This pattern is distinct from other aphasias. Global aphasia would produce nonfluent, markedly impaired speech along with comprehension and naming problems. Transcortical sensory aphasia can look similar in fluency and comprehension, but repetition is preserved. Conduction aphasia features fluent speech with relatively good comprehension but notably poor repetition, not severe comprehension impairment. The characteristic combination here—fluent speech with poor comprehension and naming—most closely matches Wernicke's aphasia, usually stemming from damage to the left posterior superior temporal gyrus.
