Brain Lateralization

Broca's Aphasia

The video above is a demonstration of a patient with damage in the Broca's area of the brain. As you can see, it is extremely difficult and even almost impossible for this patient to "speak his mind".

Language is an essential and complex tool for communication among human beings.  Imagine how frustrating and difficult it would be to  not be able to say what you are thinking???  How difficult it would be to express your ideas??

The Broca's area contains motor neurons and is located in the frontal part of the left hemisphere.  This area is associated with the production of language. In 1861, Paul Broca, a french surgeon, identified the Broca's area and found that damage to this small area of the brain impairs language production.

Broca's Aphasia is characterized as a consequence of injury to the brain caused mostly  by a stroke.  Other causes come from head trauma, brain tumors, or infection.This condition limits speech output, vocabulary access, and writing.
Affected people omit prepositions, pronouns, conjunctions, helping verbs, quantifiers, tenses and number endings. People with Broca's Aphasia rely solely on nouns and verbs to communicate.  This condition is also known as Nonfluent Aphasia because of the halting and effortful quality of speech.  It is important to know that damage to the Broca's area does not impair intelligence and it can affect people of all ages.  According to the National Aphasia Association, over 1,000,000 Americans live with aphasia every day.

  2. That is a really good thing that it doesn’t affect intelligence. Is there any form of therapy or anything that can be done to help fix this problem, or is it something that you have to live with for life? When you say it affects language production, does that mean that if someone with broca’s aphasia learned sign language they would still have problems communicating?

  3. I can't even imagine the frustration in not being able to communicate with someone, when I read articles like these it makes me realize how much everyday tasks we take for granted. And whats even worse is this is most likely caused by a stroke so people who could speak can no longer speak, it would be absolute torture knowing what you used to be able to do and can't anymore.
