Wernickes Aphasia

This video is from the same study as the video above (Brocas Aphasia). As you can tell, while the subject is speaking a great deal more than the man in the first video, it is much more difficult to follow the conversation.


How does comprehension vary between those with Brocas Aphasia and those with Wernickes Aphasia? What other types of aphasia are there, and what are their main symptoms?
