Mixed transcortical aphasia. On relative sparing of phonological short-term store in a case.
A case of Mixed Transcortical Aphasia is reported. The patient showed completely impaired verbal comprehension and speech production, with preservation of automatic speaking and singing; repetition was relatively spared. A detailed study of word and nonword repetition is reported, in order to demonstrate that the patient's residual repetition ability is based on relative sparing of short-term phonological store.
