Conduction Aphasia

A type of fluent aphasia characterized by an impaired ability to repeat one and two word phrases, despite retained comprehension. This condition is associated with dominant hemisphere lesions involving the arcuate fasciculus (a white matter projection between Broca's and Wernicke's areas) and adjacent structures. Like patients with Wernicke aphasia (APHASIA, WERNICKE), patients with conduction aphasia are fluent but commit paraphasic errors during attempts at written and oral forms of communication.

Drugs and Biologics

Drugs and Important Biological Agents (IBA) related to Conduction Aphasia:

1.	Glucose (Dextrose)FDA LinkGeneric 01/01/1989 - "Cerebral glucose metabolism in Wernicke's, Broca's, and conduction aphasia." 03/01/1988 - "Ten patients with conduction aphasia were studied with computed tomography and 18-F-fluorodeoxyglucose positron emission tomography to examine glucose metabolism. "
2.	XenonIBA 06/01/1991 - "In order to investigate functional cortical reorganization during recovery from conduction aphasia, regional cerebral blood flows (rCBF) were measured by the two-dimensional 133 Xenon inhalation method in ten stroke patients. "
3.	Temazepam (Nocturne)FDA LinkGeneric 09/01/2009 - "Additional topics of discussion include the functional organization of the planum temporale for spatial hearing and speech-related sensory-motor processes, the anatomical and functional basis of a form of acquired language disorder, conduction aphasia, the neural basis of vocabulary development, and sentence-level/grammatical processing."
4.	Sodium Glutamate (Accent)IBA 11/01/2013 - "Less frequent subtypes (total n=40; 6.7%) included transcortical aphasia (n=11), Wernicke aphasia (n=10), conduction aphasia (n=7), aphemia (n=3), semantic aphasia (n=3), crossed aphasia (n=3), pure word deafness (n=2), and foreign accent syndrome (n=1). "
5.	MetrizamideFDA Link 03/01/1988 - "Conduction aphasia following metrizamide myelography."
6.	APTIBA 01/01/2006 - "Wake Forest, NC: Lash & Associates.; APT-II], when applied in the context of a multiple baseline ABA design, would improve the attention abilities of RW, a patient with mild conduction aphasia and concomitant attention and working memory deficits. "

Therapies and Procedures

1.	Artificial Respiration (Mechanical Ventilation) 12/01/2002 - "Once these complications were corrected, he was weaned from mechanical ventilation and the following neurological signs were observed: temporal and spacial disorientation, aphasia, ophthalmoplegia with divergent strabismus and later conduction aphasia, amnesia and confabulation. "
2.	Injections 09/01/1997 - "In the six patients with temporoparietal AVM, anesthetic injections into vessels in the lower division of the middle cerebral artery (MCA) not feeding the AVM (e.g., the left angular artery) produced a wide range of language function--from conduction aphasia to dense Wernicke's syndromes.
