Dissimilar to the others, it occurs in the case that the lesion is present on the border between medial and posterior, or anterior and medial. If the lesion is in front, the patient is able to understand what is said but never speaks. If it’s at the back, it would be like Wernicke’s aphasia. If it’s located on both sides, it would be a transcortical mixed aphasia. Regardless of the type it is of, this is an aphasia in which repetition is perfectly preserved. Its communication with other networks is impaired, although it is only the language networks that is not impaired. That’s why repetition is preserved.
