E776691

aphasia language disorder neurogenic communication disorder

Conduction aphasia is a language disorder typically caused by damage to the arcuate fasciculus, characterized by relatively fluent speech and good comprehension but marked difficulty repeating words or phrases and frequent phonemic paraphasias.
