√ This week we went over speech disorders. Aphasia falls under the speech disorders category. There are two types of aphasia: Broca’s and Wernicke’s (Heilman, 2002, p. 11).
√ There are many language symptoms of Broca’s aphasia. The difference between naming objects and using grammatical terms is a trademark of Broca’s apahsia. Mr. Ford was a patient that experienced this type of aphasia. This type of aphasia includes patterns of speech that mostly are made up of content words. Also people with this aphasia convey nouns in their singular form and their verbs in their most uncomplicated form. Another issue that those with Broca’s aphasia have is a hard time beginning an utterance. Speech that is more intellectual also isn’t very common (DiNapoli, 2012, p. 48).
When talking about Wernicke’s aphasia there are also many language symptoms. Those suffering from Wernicke’s aphasia have no problem with speech, but their speech isn’t fluent and doesn’t make sense (DiNapoli, 2012, p.52). Mr. Gorgan experienced psychotic speech (DiNapoli, 2012, p. 53). If the lesion that caused this aphasia wasn’t entirely eliminated, output might slowly improve. On the other hand, if this lesion has been eliminated, the patient will more than likely not be able to talk like they once did ever again, no matter how much therapy they receive or treatment (DiNapoli, 2012, p. 54). When Grogan was told to identify objects around him, he was only successful with those most familiar to him (DiNapoli, 2012, p. 55).
When referring to Broca’s aphasia, patients are usually right-handed, and typically have a frail right arm. In studying his patients, he proved that the left hemisphere is influential for reconciling language in people who are right-handed (Heilman, 2002, p. 13). The capability to speak is affected in Broca’s aphasia, whereas comprehending speech is not (Heilman, 2002, p. 12).
The other type of aphasia talked about was Wernicke’s aphasia. Unlike Broca’s aphasia, in Wernicke’s aphasia, sensory information journeys from a particular organ to a transmitting station known as the thalamus. After arriving at the thalamus, it’s sent to the cerebral cortex. In short, Wernicke’s area is responsible for remembering how words sound (Heilman, 2002, p. 15).
Broca proved that the brain’s anterior areas which are critical for planning sounds of speech and the left hemisphere is influential in mediating language in people that are right-handed (Heilman, 2002, p. 13). During studies, it was also found that the frontal part of the left hemisphere is critical for producing speech used in conversation, and the frontal parts of the right hemisphere might be needed for singing and automatic speech. When a CT scan was done of an Orthodox Jew, the scan showed that the patient had a stroke that impacted the frontal portion of his right hemisphere (Heilman, 2002, p. 14). So, the typical brain lesion sites that precipitate Broca’s aphasia are when damage is done to the left frontal lobe...
