Furthermore, plastic changes in the brain may lead to the recruitment of new pathways to restore lost function. As aphasias and other language disorders are frequently due to stroke, their symptoms can change and evolve over a;hasie, or simply disappear. Aphasias Stroke Parietal lobe. This challenges the arcuate fasciculus theory, and it apnasie been suggested that a cortical lesion, not a disconnection, is the crucial factor. Get free access to newly published articles.

Lesions of spinal cord and brain. However, patients recognize their paraphasias and errors and will try to correct them, with multiple attempts often necessary for success.

Conduction aphasia

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 confrontation tasks such as repetition, reading and naming in a similar manner.

However, chronic conduction aphasia is possible, without transformation to other aphasias. Later work and examination of brain structures, however, implicated the arcuate fasciculusa white matter bundle connecting the posterior temporoparietal junction with the frontal cortex.

They had a severe deficit in auditory comprehension. The brain damage causing conduction aphasia is often from a strokewhich can produce both localized and widespread damage. Lesions in this area that damage the sensorimotor dorsal stream suggest that the sensory system aid in motor speech. Regardless sphasie the role that the arcuate fasciculus plays in the disorder, the cortical component aphasiw be denied. Current Neurology and Neuroscience Reports.

There have been no known autopsy cases in which conduction aphasia was shown to be the result of a focused arcuate fasciculus lesion. Sigmund Freud would argue in that the old framework was inaccurate; the entire perisylvian area, from the posterior to the anterior regions, were equivalent in facilitating speech function.

These patients could speak fluently, but their speech lacked meaning. Speech will often contain paraphasic errors: This hypothesis fits well with the Wernicke-Geschwind model of language, which compartmentalizes and localizes speech comprehension and production.

They are fully capable of understanding what they are hearing, but fail to encode phonological information for production.

“aphasie de conduction” in English

Left-hemisphere damage involving auditory regions often result in speech deficits. Recent research has pointed to a different explanation for conduction aphasia, similar to Wernicke’s, which is based on newer models suggesting language is facilitated by “cortically based, anatomically distributed, modular networks. Several standardized test batteries exist for diagnosing and classifying aphasias. Create a free personal account to make a comment, download free article PDFs, sign up for alerts and more.
