Cerebral lesions may alter the capability of bilingual subjects to separate their languages and use each language in appropriate contexts. Patients who show pathological mixing intermingle different within a single utterance. By contrast, patients affected by switching alternate across utterances (a self contained segment speech that stands on its own conveys independent meaning). Cases have been reported after left temporoparietal lobe. information neural loci involved is scarce. In this paper description given for first time patient with lesion anterior cingulate frontal lobe—also marginally involving right area—who presented between absence any other linguistic impairment. Thus, unlike typically occurs aphasia, be mechanisms.
