Conduction aphasia was originally proposed to result from separation of the posterior language Hécaen H, Dell MB, Roger A: L’aphasie de conduction. Three patients with conduction aphasia are described; in addition to the distinctive language disorder, Hécaen H, Dell MB, Roger A: L’aphasie de conduction.

Later work and examination of brain structures, however, implicated the arcuate fasciculusa white matter bundle connecting the posterior temporoparietal junction with the frontal cortex.

Meynert also distinguished between the posterior and anterior language systems, leading Wernicke to localize the two regions. Meanwhile, Carl Wernicke described patients with receptive aphasiawho had damage to the left posterior superior temporal lobe, which he named “the area of word images”. Furthermore, there are reports of patients with severe disruption of the arcuate fasciculus who show no symptoms cohduction conduction aphasia although it is plausible that the contralateral hemisphere facilitated repetition in these cases.

“aphasie de conduction” in English

condutcion It was thought that this bundle transmitted information between Wernicke’s area responsible for language comprehension and Broca’s area responsible for language production. Traumatic brain injury and tumors can also lead to localized lesions, with potential to cause conduction aphasia.

Neck mass Cervical lymphadenopathy. M; Nadeau, S; Beversdorf, D. Conduction aphasiaalso called associative aphasiais a relatively rare form of aphasia.

Conduction aphasia is a relatively mild language impairment, and most patients return to day-to-day life. When this area is damaged, the patient experiences damage to the auditory-motor integration system. Create a personal account to register for email alerts with links to free full-text articles.

What brings you to the hospital? Conduction aphasia is caused by damage to the parietal lobe of the brain, especially in regards to the area associated with the left-hemisphere dominant dorsal stream network. Norman Geschwind proposed that damage to this bundle caused conduction aphasia; the characteristic deficits in auditory repetition were due to failed transmission of information between the two language centers.

Regardless of the role that the arcuate fasciculus plays in the disorder, the cortical component cannot be denied. This challenges the arcuate fasciculus theory, and it has been suggested that a cortical lesion, not a disconnection, is the crucial factor.

Three new cases in which the lesion does not lie in the arcuate fasciculus are reported, two in left-handed patients with left temporoparietal lesions and one in a righthanded patient with a right cpnduction infarct, a “crossed” aphasia.
