Wernicke's Aphasia


A bit about the history of Wernicke’s Aphasia: In 1874, Carl Wernicke, a junior assistant in a German hospital, discovered that damage in part of the left temporal cortex produced certain kind of language impairment. Damage in Wernicke's area produces this disorder.  He called this disorder sensory aphasia, which became known as Wernicke's aphasia.
                                               

 Damage in Wernicke’s area produces Wernicke’s aphasia, also known as fluent aphasia. A patient with Wernicke’s Aphasia does not appear to have any difficulty articulating speech, but may be paraphasic. However, comprehension of speech is impaired and sometimes as much as single words are not comprehended.

People with Wernicke’s Aphasia speak fluently but have much trouble finding the names of objects and a lot of times they make up names. When having found the words, they say them in an order which isn’t understandable. Their writing ability can also be illegible. In some cases, people with this disorder don’t understand the spoken language.
This is a video of someone showing symptoms of Wernicke's Aphasia.
 
We can imagine how extremely difficult and frustrating it must be for these people to live this way. They can speak fluently, yet anything they say makes no sense. Also, hearing someone talk to them but not being able to comprehend what they are saying. It is almost as if these people don’t have the ability to talk.

For this disorder, there are no surgical or medical procedures to treat it. The only treatment available for patients with this disorder is speech and language therapy. Some patients happen to recover completely without any forms of treatment.

  1. Pretty interesting how a small area of the brain can limit a person's main communication tool, speech. After watching the video, I realized how fortunate I am to be able to express my ideas through speech. To my understanding, patients with Fluent Aphasia have trouble naming objects, imagine how hard it would be to ask for water and not be able to say the word "water"... Both Broca's aphasia and Wernicke's aphasia are language disorders that affect people in their daily lives.

  2. That is very interesting, by any chance would damage to wernicke’s area impair other forms of communication or is it speech and comprehension in general, for example if someone had damage to wernicke’s area would they be able to learn sign language and use it without a problem, or would they struggle with it just as they do with the language they speak?
