Translation for ‘aphasie de conduction’ in the free French-English dictionary and many other English translations. 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.

An Introduction to Neurogenic Communication Disorders, 6e. To Freud and Goldstein, conduction aphasia was thus cnduction result of a central, core language breakdown; Goldstein labeled the disorder central aphasia. Wernicke was influenced by Theodor Meynerthis mentor, who postulated that aphasias were due to perisylvian lesions.
The arcuate fasciculus has been the most frequently suggested site of such a disconnection, but the syndrome has been reported in cases in which the abnormality involved the dominant Wernicke’s area. Lesions in this area that damage the sensorimotor dorsal stream suggest that the sensory system aid in motor speech.
Intonation and articulation will also be preserved. Wernicke predicted the existence of conduction aphasia in his landmark monograph, Der Aphasische Symptomenkompleks: This recognition is due to preserved auditory error detection mechanisms.

What brings you to the hospital? He did not explicitly predict the repetition deficit, but did note that, unlike those with Wernicke’s aphasia, conduction aphasics would be able to comprehend speech properly, and intriguingly, would be able to hear and understand their own speech errors, leading to frustration and self-correction.
The brain damage causing conduction aphasia is often from a strokewhich can produce aphasid localized and widespread damage. However, recent reviews and research have cast doubt on the singular role of the arcuate fasciculus and the model of spoken language in general [ citation needed condjction.

Conduction aphasia – Wikipedia
Furthermore, there are reports of patients with severe disruption of the arcuate fasciculus who show no symptoms of conduction aphasia although it is plausible that the contralateral hemisphere facilitated repetition in these cases.
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.

Psychology the science of behaviour 4th ed. Neck mass Cervical lymphadenopathy. This results in disruption to the delayed auditory feedback network, causing the individual to have difficulty correcting themselves on speech repetition tasks. Norman Geschwind proposed that damage to this bundle caused conduction aphasia; the conductiln deficits in auditory repetition were due to failed transmission of information between the two language centers.

Shallice and Warrington were able to differentiate two variants of this constellation: Traditionally, it has been believed that conduction aphasia was the result of a lesion in the arcuate fasciculusa deep, white matter bundle connecting the posterior temporoparietal junction with the frontal cortex. Later work and examination of brain structures, however, implicated the arcuate fasciculusa white matter bundle connecting the posterior temporoparietal junction with the frontal cortex.

Aphasie de conduction par trouble phonémique – EM|consulte
Wernicke, and later Lichtheim and others, theorized that a disconnect between these two regions caused patients to fail to monitor speech and limited their ability to transfer information between comprehension and production functions, thus leading to paraphasic errors and a deficit in repetition of auditory input.
They will also be aware of their errors, and will show significant confuction correcting them. Postmortem examination revealed that the two patients with apraxia had entirely suprasylvian lesions involving the white matter deep to the parietal operculum, while the nonapraxic subject had suffered total destruction of the Wernicke area.

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 temporoparietal infarct, a “crossed” aphasia.
From Wikipedia, the free encyclopedia. These authors suggested an exclusive deficit of auditory-verbal short-term memory in repetition conduction aphasia whereas the other variant was assumed to reflect disrupted phonological encoding mechanism, afflicting dr tasks such as repetition, reading and naming in a similar manner.
