Question: I've heard many time about Epileptic Aphasia but don't know what it is. Could somebody explain this to me? is it the name of a disease?? Can anyone give me some suggetionsor tell me some thing that you think neccesary to know what it is.Or can anyone be kindful to help me find some source of information??? I'm very curious in it.
Answer: An aphasia is a language deficit. For example, a patient can havetrouble speaking or expressing verbally the thoughts that he or she has-- i.e., Broca's aphasia -- or a patient can have trouble understandingor comprehending the speech that other people say to the patient --i.e., Wernicke's aphasia. Broca's Area -- named after Paul Broca, a French histologist, a tissuedoctor -- is a region in the front of the left temporal lobe of thebrain that becomes active when a person is talking -- above and in frontof the ear. The patient may be able to speak individual words fluentlybut sometimes the words are not put together grammatically in a sentenceand the sentence comes out garbled with the semantics of the sentencenot making sense-- this is sometimes referred to as Word Salad, becausethere are a lot of verbal ingredients that are all mixed up together. Wernicke's Area -- named after Karl Wernicke -- is a region in the lefttemporal lobe further back on the side of the left temporal lobe aboveand behind the left ear, and this area becomes active when a person islistening to the language spoken by other people. Broca's area and Wernicke's area have been studied as language areas ofthe brain for a long time. For example, there was a famous case studyof a person name Phineas Gage who was working on a railroad layingtracks -- long long ago. When he hit one of the spikes for the track,part of the metal spike flew up and hit him in the left side of his headand brain. He developed a language deficit - aphasia - because the partof his brain that was damaged by trauma just happened to be the part ofthe brain that controls language function. Doctors studied his brainand the location of the trauma that he sustained and they deduced thatthe part of his brain that was damaged was the language area thatcontrolled his speech.
