This deficit is load-sensitive as patients show significant difficulty repeating phrases, particularly as the phrases increase in xe and complexity and as they stumble over words they are attempting to pronounce.

Several standardized test batteries exist for diagnosing and classifying aphasias.

Later work and examination of brain structures, however, implicated the arcuate fasciculusa white matter bundle conduvtion the posterior temporoparietal junction with the frontal cortex. Furthermore, plastic conducrion in the brain may lead to the recruitment of new pathways to restore lost function.
