Aphasia, Conduction

Ledningsafasi

Svensk definition

En form av talrubbning förknippad med störning i den dominanta hjärnhalvan orsakad av avbrott på nervsträngen mellan Brocas och Wernickes areor. Taluppfattningsförmågan är normal, men den drabbade förväxlar ord och återger fraser felaktigt (parafrasi).

Engelsk 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.
