ABSTRACT
Verbal productions may be effortful but articulation and grammar are usually normal, particularly when the anterior speech area and the adjacent inferior motor cortex are spared. By contrast, effortful and laboured articulation may accompany cases of Mixed Transcortical Aphasia (MTCA) secondary to left perisylvian area damage. The syndrome of MTCA has been described in association with either cortical or subcortical lesions of the left hemisphere. The most common causes of MTCA from cortical damage are lesions that involve the anterior and posterior border-zone areas. Upon neurological examination, the patient showed right hemiparesis and features of MTCA together with alexia without homonymous hemianopia or agraphia (subangular alexia), impaired naming, and colour agnosia. Moreover, most studies on MTCA have approached the aphasie syndrome from a neuroanatomical perspective, whereas cases interpreted within the cognitive neuropsychological model are rare and some of them focused on the analysis of cognitive functions in other linguistic domains.
