Which aphasia is labeled as mixed transcortical/isolation aphasia?

Mixed transcortical/isolation aphasia describes a pattern where the language cortex is effectively cut off from the surrounding language networks by damage in watershed regions. This leads to very limited spontaneous speech and poor comprehension, but repetition remains relatively preserved because the repetition circuitry (the pathways connecting Broca’s and Wernicke’s areas) is spared. In short, you see severe language production and understanding problems with intact repetition, which is the hallmark of this isolation-type transcortical syndrome. This differs from other aphasias where repetition is impaired or where language output and comprehension are both severely disrupted, helping to identify the mixed transcortical (isolation) profile.
