Cause And Effect Of Brroca's Aphasia

841 Words 4 Pages
Aphasia is a condition that enables a person to comprehend and express language caused by a dysfunction in the brain. Through language people communicate their inner thoughts, desire, intention, and motivations. They also understand what others have to say, ask questions, give commands, listen, speak, read and write. But when there is damage in the left hemisphere of the brain this is impossible. Broca’s aphasia is a speech disorder that results from damage to the Broca’s area in the left frontal lobe of the brain (Myers, 2011). Broca established that the section of the brain called the inferior frontal gyrus is most responsible for speech conveyance, and the Broca’s area lies within the border region of the inferior gyrus (Keller, Crow, Foundas, …show more content…
An example that illustrates how the information pathway can malfunction is when reading aloud, the message from the passage goes into the visual sensory area, then it’s transformed in auditory signals by the anterior gyrus, processed by the Wernicke’s area, and lastly received by the Broca’s area which it instructs the motor cortex how to form speech pronunciation. If the Broca’s area and the surrounding tissues are damaged then they cannot be coordinated and therefore speech is not produced (Meyer, 2011, Keller et al., 2009). Speech is not formed from just one single spot in the brain, but different words and definitions can be stored in numerous places (Forgie, 2008). Patients that have damaged the left frontal lobe of the brain can still manage to learn and comprehend language all over again but this time with the right side of the brain. With the right therapy patients well learn little by little to re- train the left side of the brain if there isn’t much damage on that side of the brain. Otherwise the right side must take over and start from …show more content…
Melodic Intonation Therapy will be given in short, frequent session that can last at least 30 to 60 minutes. These sessions will last about 3 to 6 weeks. During the MIT session the patient will be encouraged to hum, and then sing words or phrases that the patient finds hard to call, while also tapping out a rhythm. This will increase the number of words the patient can recall because the part of the brain we use to recall song lyrics and music is different from the part of the brain we use to recall language. This therapy uses intonation patters that help increase the length of phrases and sentence. The dependence on the intonation will decrease over the time period. The participant will be able to then recall large amounts of phrases and sentences on their own. Though out the sessions the patient’s progress will be recorded to see how far and how much has been
