•Motor speech area of Broca
- inferior frontal gyrus between the anterior & ascending rami & the ascending & posterior rami of lateral sulcus
- important on the left (majority)
- paralysis of speech (expressive aphasia)
- retain the ability to think the words they wish to say, can write the words & understand their meaning
- speech is produced with great effort & poor articulation, in brief utterances & word errors
- comprehension preserved
Broca's aphasia is sometimes called disfluent aphasia or agrammatic aphasia. It is named after Pierre-Paul Broca (1824-1880), a French surgeon and anthropologist who first described the syndrome and its association with injuries to a specific region of the brain.
Agrammatism typically involves laboured speech, and a lack of use of syntax in speech production and comprehension (although patients who present with agrammatic production may not necessarily have agrammatic comprehension).
well, for a moment, imagine u hv expressive aphasia..
An example of agrammatic speech:
Ah ... Monday ... ah, Dad and Paul Haney [himself] and Dad ... hospital. Two .. .ah, doctors ... and ah ... thirty minutes .. .and yes ... ah ... hospital. And, er, Wednesday ... nine o'clock. And er Thursday, ten o'clock .. .doctors. Two doctors ... and ah ... teeth. Yeah, ... fine.
The second classical aphasic syndrome is named after the German neurologist Carl Wernicke (1848-1905).
Wernicke's aphasia is sometimes called sensory aphasia or fluent aphasia.
The speech of a Wernicke's patient is often a normally-intoned stream of grammatical markers, pronouns, prepositions, articles and auxiliaries, with difficulty in recalling correct content words, especially nouns (anomia). Words may be meaningless neologisms (paraphasia).
The patient in the passage below is trying to describe a picture of a child taking a cookie.
C.B. Uh, well this is the ... the /dodu/ of this. This and this and this and this. These things going in there like that. This is /sen/ things here. This one here, these two things here. And the other one here, back in this one, this one /gesh/ look at this one.
Examiner Yeah, what's happening there?
C.B. I can't tell you what that is, but I know what it is, but I don't now where it is. But I don't know what's under. I know it's you couldn't say it's ... I couldn't say what it is. I couldn't say what that is. This shu-- that should be right in here. That's very bad in there. Anyway, this one here, and that, and that's it. This is the getting in here and that's the getting around here, and that, and that's it. This is getting in here and that's the getting around here, this one and one with this one. And this one, and that's it, isn't it? I don't know what else you'd want.
Wernicke's patients seem to suffer from much greater disorders of thought than Broca's patients, but even so, Broca's is expressive aphasia.. they are unable to express themselves fluently.. (tension,ok bcoz u cant say it out wut's inside..) so they are said to be unhappier than Wernicke's patients, who are often blissfully unaware that nothing they say makes any sense at all,(receptive aphasia) and whose higher-level thinking processes are often as haphazard as their language is.
*well, either Broca or Wernicke.. bersyukur sy ada speech area.. utk memahami dan difahami..
p/s: nen.. i think u wernicke lah.. =p
