Which type of fluent aphasia might involve higher than normal words per minute (WPM)?

Transcortical sensory aphasia is characterized by fluent speech with relatively normal articulation and significantly higher than normal words per minute (WPM). Individuals with this type of aphasia can produce long, verbose sentences; however, the content may lack meaningful coherence or relevance. They often exhibit good sentence structure but struggle with understanding spoken language and may repeat phrases or sentences without grasping their meaning.

This ability to generate speech rapidly contrasts with other types of aphasia. For instance, Broca's aphasia is marked by non-fluent speech with a reduced WPM due to difficulties in speech production, while global aphasia involves severe impairments in all aspects of language, leading to very limited verbal output. Mixed transcortical motor aphasia, although it can have some fluent elements, also includes significant difficulties with initiating speech and may not consistently demonstrate an increased WPM like transcortical sensory aphasia does. Thus, transcortical sensory aphasia stands out for its capacity for fluent, albeit sometimes nonsensical, speech patterns.
