Aphasia is classified as a language disorder caused by damage to the temporal lobe or damage higher up in the frontal lobe. It causes problems with receptive and expressive functions. Aphasia is damage in understanding and establishing complex, meaningful elements of language. It causes problems with words and word order making difficulties in reading and writing. There are many ways to test that Mr. McGeorge has symptoms that would lead me to believe that the damage that was taken on him was located in the three different areas.
The Broca's area is the section of the human brain, which is located in the lower front gyrus of the frontal lobe of the cerebral cortex, which is involved in language processing, such as speech, in production and understanding. Broca's aphasia is noticeable that involves a lack of ability to demonstrate coherent language, including spoken, written and signed forms. Patients suffering from Broca's aphasia are able to use the organs of speech, the articulators, to demonstrate sounds and even single words, but they cannot demonstrate sentences or express thoughts. Often, patients will find one word or a short string of words and repeat them over and over in an attempt to communicate thoughts, and may sometimes be successful in communicating, but they will not be able to grammatically express themselves. Similarly they can draw, but are not capable of writing coherent speeches. The key is that they can understand speech, and often can form ideas to communicate, but they cannot put words together to communicate those ideas. It is involved in assessing the grammar and structure of speech while listening. Speech is transported from the auditory area to Wernicke's area for evaluation of the significance of content words, then to Broca's area for analysis of grammar. The area is named after Paul Pierre Broca, who first described it in 1861, who observed the effects of damage and conducted a post mortem examination. It is connected to Wernicke's area by a neural pathway called the arcuate fasciculus.
