QuestionAnswer
A 70-yr-old man has a stroke which causes him to have the following findings on neurological exam: right/left confusion and difficulty subtracting serial 7's. Where is the stroke and what other findings might he have on examination? Dominant parietal lobe: agraphia. Damage to the inferior parietal lobe of the dominant hemisphere results in the Gerstmann syndrome which includes right/left confusion, finger agnosia, acalculia and agraphia.
A patient with Wernicke's aphasia would have which one of the following findings on examination? A. Slow, nonfluent speech. B. Can understand a sentence but cannot repeat it. C. Has telegraphic speech. D. Cannot follow a command.
Explain functional defect in Wernicke's aphasia? Patients with Wernicke's or receptive aphasia cannot understand what is said to them. Their speech may be fluent but devoid of meaning.
A patient has the sudden onset of inability to talk. He understands what is said to him but can only say "if only" and "oh no." Where is the lesion? A. Left superior temporal gyrus. B. Left parietal lobe - angular gyrus of the parietal lobe. C. Left inferior frontal gyrus. D. Both the superior temporal gyrus and inferior frontal gyrus on the left.
Describe the clinical result of a lesion in Broca's area, where is it? A lesion in the dominant inferior frontal gyrus or Broca's area would result in an expressive aphasia where comprehension is preserved but speech output is impaired. The resulting speech is nonfluent, telegraphic and often minimal.
An example of apraxia is which one? A. can't name colors B. difficulty saying multisyllablistic words C. inability to show he can cut with imaginary scissors. D. difficulty with understanding the emotional & affective component of what is said to them C. Apraxia is the inability to perform a purposeful motor act on command. It can seen in lesions of the dominant parietal lobe.
A pt can repeat a 5-digit span forward and backward and is able to list 5 months backwards. He is unable to remember a list of four objects given to him five minutes previously. This type of memory problem would be found in a ds. affecting which lobe? Temporal lobe.
Frontal lobe has which basic functions? attention and working memory tasks
Testing gnosis and praxis are needed to functions of which lobe? Parietal lobe function
Tests that involve visual recognition tasks are needed to examine which lobe function? occipital lobe function.
When asked to draw a clock, a 64 yr-old crowds all the #s onto the R side with the #s trailing off below the lower border of the clock; drawing a face, she draws a profile of the R side of the face. Pt most likely has a lesion in what part of the brain? The patient is having trouble with visual spatial sensory tasks. She is neglecting the left side of space which indicates dysfunction of the right parietal lobe.
A pt having trouble recognizing visual objects would localize what brain area? R inferior temporal occipital association cortex.
Which lobe dysfunction would manifest itself in memory problems? Limbic lobe
Executive functions such as set generation, problem solving, and attention involve which part of the brain? The dorsal lateral frontal lobes
Pt with difficulty understanding the emotional and affective components of receptive language localizes which part of the brain? The nondominant superior temporal gyrus
A pt having problems with executive function, personality change and motivation suggests a lesion where? frontal lobe
Which brain area is important for emotional memory and reactions to fearful and stressful experiences? The amygdala
Autotopagnoisa is the inability to localize body parts of one's own body or those of another person. This type of deficit is seen with lesions of the ____? left posterior parietal lobe.
A 45-year-old man can identify colors and name objects but cannot recognize a familiar face. This deficit is _________ and is caused by a lesion in the _________ of the brain. Prosopagnosia; inferior occipital temporal cortex. this problem is usually caused by bilateral inferior occiptotemporal lesions.
A patient has difficulty spelling "world" backwards, listing months of the year backwards, and repeating a digit span backwards. This would indicate a problem with _______ memory from dysfunction of _______ area of the brain. Working; frontal cortex.
A patient cannot recognize familiar objects placed in her right hand when her eyes are closed but she has no trouble with her left hand. This is called _______ which is from a lesion in the _______ of the brain. Astereognosia; parietal cortex.
