Compare and contrast the symptoms noted in Broca's aphasia and in Wernicke's aphasia.
What will be an ideal response?
Broca's aphasia entails difficulty in speech articulation, word choice (anomia), and using grammar (agrammatism). A person suffering from Broca's aphasia is better able to comprehend speech than to produce speech. In contrast, Wernicke's aphasia is characterized by fluent speech that is meaningless, and this form of aphasia-unlike Broca's-is characterized by poor speech comprehension. In addition, a person with Wernicke's aphasia seems unaware of his or her speech deficits. Broca's aphasia is produced by damage to tissue in and around Broca's area, whereas Wernicke's is produced by damage to the superior temporal lobe of the left hemisphere.
