Definition

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-- (From Adams et al, Principles of Neurology, 6th ed, p482; Brain & Bannister, Clinical Neurology, 7th ed, p142; Kandel et al, Principles of Neural Science, 3d ed, p848)-----------
