Mixed transcortical aphasia is the least common of the three transcortical aphasias (behind transcortical motor aphasia and transcortical sensory aphasia, respectively). This type of aphasia can also be referred to as "Isolation Aphasia". This type of aphasia is a result of damage that isolates the language areas (Broca’s, Wernicke’s, and the arcuate fasiculus) from other brain regions. Broca’s, Wernicke’s, and the arcuate fasiculus are left intact; however, they are isolated from other brain regions.
