CONCLUSION Conduction aphasia is a fluent aphasia,with good comprehension,poor repetition, paragrammatic errors,anomia,paraphasic,good recitation,and good reading aloud.While any type of paraphasia may be seen,the vast majority of substitutions involve phonemes resulting in literal( phonemic) paraphadic errors. The lesion usually involves the left inferior parietal lobule,especially the anterior supramarginal gyrus. Often the lesion is in the subcortical white matter,deep in the inferior parietal cortex,involving the arcuate fasciculus or the external capsule immediately below it-- both structures are connected to the temporal and frontal cortex.
