Differential effects of left and right cerebral vascular accidents on language competency

While language facility was once considered to be the sole province of the “dominant” left hemisphere, clinical and experimental findings suggest the right hemisphere plays an equally important role in many language tasks.

Description
Summary:While language facility was once considered to be the sole province of the “dominant” left hemisphere, clinical and experimental findings suggest the right hemisphere plays an equally important role in many language tasks. To elucidate differential hemispheric language processes, Right Hemisphere Language Battery and Western Aphasia Battery data from left (LHD) and right (RHD) hemisphere cerebral vascular accident (CVA) patients and controls were subjected to multivariate discriminant analysis. The highly significant group differences and overall 95% classification rate obtained confirms the utility of the dependent measures in differential diagnosis. Results suggest CVA patients experience disparate language deficits, with the LHD group experiencing concordant-convergent language deficits and the RHD group displaying discordant–divergent deficits that interfere with the receptive and expressive language skills necessary for successful social discourse.
