Multiple Choice

Which aphasia is described as non-fluent with preserved repetition, according to certain cortical patterns?

Non-fluent speech with preserved repetition indicates a pattern where the ability to initiate and produce spontaneous speech is disrupted, but the system for repeating phrases remains intact. This points to transcortical motor aphasia. The lesion is typically anterior to Broca’s area or in the supplementary motor area, disrupt­ing speech initiation while sparing the neural pathways that support repetition, so repeating what is heard can be preserved or easily cued. Think about the other syndromes: fluent aphasias with poor comprehension (like Wernicke’s) aren’t non-fluent; global aphasia is non-fluent with severe deficits across language modalities including repetition; transcortical sensory aphasia is fluent with preserved repetition but impaired comprehension. The described combination best fits transcortical motor aphasia.
