title: Language and visuospatial impairment in a case of crossed aphasia.
abstract: Crossed aphasia in dextrals (CAD) constitutes an interesting model for understanding the lateralisation and interaction of language with other cognitive functions in the brain. The authors present a study of a right-handed patient with Wernicke's aphasia following a right hemisphere cerebrovascular accident, who also had impairment in visuospatial skills. Although the patient presented a remarkable improvement in language symptoms on longitudinal follow-up, the combination of linguistic, visuospatial, and attentional impairments ultimately resulted in a persisting inability to perform complex tasks. The study of mild residual disturbances can improve our understanding of the interaction of language with other cognitive functions, going some way towards explaining the particular features found in CAD.
