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.
These patients had lesions in the anterior perisylvian region now known as Broca’s areaand produced halting and labored speech, lacking in function words and grammar.

For example, when prompted with “bagger”, a patient may respond with, “gabber”.
Three patients with conduction aphasia are described; in addition to the distinctive language disorder, two of them had severe ideomotor apraxia alhasie the other was entirely free of apraxia. Patients are still able to comprehend speech because the lesion does not disrupt the ventral stream pathway. The brain damage causing conduction aphasia is often from a strokewhich can produce both localized and widespread damage.

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

Based on these findings and a review of the literature, we would propose the following: Topics related to Conduction aphasia. Regardless of the role that the arcuate fasciculus plays in the disorder, the cortical component cannot be denied.
Several standardized test batteries exist for diagnosing and classifying aphasias.

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 re of such a disconnection, but the syndrome has been reported in cases in which the abnormality involved the dominant Wernicke’s area.
They will also be aware of their errors, and will show significant difficulty correcting them. Create a aphasue personal account to make a comment, download free article PDFs, sign conxuction for alerts and more.

Traditionally, it has been believed that conduction aphasia was the result of a connduction in the arcuate fasciculusa deep, white matter bundle connecting the posterior temporoparietal junction with the frontal cortex.
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.
This challenges the arcuate comduction theory, and it has been suggested that a cortical lesion, not a disconnection, is the crucial factor.

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.
Wernicke predicted the existence of conduction aphasia in his landmark monograph, Der Aphasische Symptomenkompleks: While atypical, these cases offer evidence that disconnection of the circuit linking language comprehension to motor speech output, not damage to a specific cortical region, underlies the syndrome of conduction aphasia.

Later work and examination of brain structures, however, implicated the arcuate fasciculusa white matter bundle connecting the posterior temporoparietal junction with the frontal cortex. Now, I want you to say some words after me. Get free access to newly published articles.
