how can you test verbal fluency?
|
the FAS test (F's, A's, and S's). normal is somewhere between 30 and 60. Less than 12 is bad news.
ANimal naming test. normal is 18 to 22. |
|
|
what are some important broadman's areas for speech?
|
broca's area: 44 and 45 in the inferior frontal gyrus.
the primary auditory cortex is 41 and 42, and it's in the temporal operculum. wernike's area is in the superior temporal gyrus and is 21. 39 and 40 are supramarginal gyrus and angular gyrus. |
|
|
describe the speech from broca's vs. wernike's lesions:
|
broca's speech is broken up. comprehension is great. repetition and naming are bad.
wernike's speech is fluent but empty. everything else that depends on comprehension is bad (naming, repetition, etc). so they both have poor naming and repetition. broca's has comprehension, wernike doesn't. but wernike can form fluent words, broca's can't. broca's = 44 45 wernike's = 22 primary auditory cortex = 41/42 |

what's going on with middle cerebral artery problems?
|
if proximal or distal M1 (first segment):
contralateral body problem (likely face and upper limb). if it's on the left side, can loose all ability to understand and repeat (total aphasia). if on right side, have disconnection symptoms and agnosia. if it's m2, could be inferior or superior. superior feeds broca's area (broca's aphasia), inferior feeds wernike's area. if superior, also have eye deviation towards side of infarct. also can end up with face/arm problems. note that because the inferior goes backwards, you're more likely to have visual field deficits. |
|
|
talk a little more about MCA m2 inferior division symptoms:
|
because this is wernike's aphasia, they may be able to speak just fine, but they make no sense and have no comprehension - so they can seem crazy. if it's on the right side, see inattention and neglect if on the right side.
|
|
|
anterior cerebral artery language symptoms?
|
less common, but they tend to repeat everybody's sentences. = echolia.
|
|
|
what's apraxia and how do you test for it?
|
inability to do learned actions that's not accounted for by motor deficits, strength, coordination, comprehension.
this is "use a tool" problems. |
|
|
what's neglect, and where does it usually show up?
|
can be physical or visual. almost always happens on the left side as a result of right-sided brain issues.
neglect can be tested for by putting a remote control next to someone's left hand, telling them to grab it, and grabbing it with the right. visually, it has to be separated from visual field deficits. |
|
|
what's the hallmark of posterior cerebral artery problems?
|
visual field deficits, since its big job is to feed the occipital lobes. note that the right side sees things on the left side of both eyes, and the reverese on the right side.
called honomymous hemianopinia. gets better in 50% of patients. |
|
|
what is alexia without agraphia?
|
left posterior cerebral artery lesion usually causes.
screws up the splenium of the corpus calossum and the left visual center. so, visual information only comes into the right half of the brain. this info can't be sent to wernike and broca's area. so, can't read. but can still write 'cause all the frontal lobe/muscle control areas are fine. |
|
|
what do you typically test for with speech?
|
VCR NRW.
verbal fluency (fas test, etc) comprehension (larger and larger words) repetition (larger and alrger) naming reading writing. |
