1

Define agnosia

inability to perceive/understand the import of sensory stimuli despite intact sensory mechanisms. perception devoid of meaning.

2

define anosagnosia

inability to recognize own neurological deficit.

3

define apraxia

inability to perform learned actions despite intact motor functions

4

define receptive aphasia

inability to understand. characteristic of Wernicke's

5

define expressive aphasia

inability to express via speech. characteristic of Broca's

6

define global aphasia

inability to comprehend, produce, repeat speech.

7

define alexia

visual agnosia. inability to read.

8

define agraphia

inability to write. Akin to expressive aphasia

9

define disinhibition

frontal lobe lesion accompanied by inappropriateness, etc

10

define dysnomia

anomia, difficulty naming items

11

define paraphasia

well-articulated but incorrect words. includes neologisms, semantic paraphasia, phonemic paraphasia

12

Language: bilateral or unilateral?

uni.

13

attention to the non-dominant world: bilateral or unilateral?

uni

14

somatic sensation: bilateral or unilateral?

uni

15

vision: bilateral or unilateral?

uni

16

voluntary motor function: bilateral or unilateral?

uni

17

hearing: bilateral or unilateral?

bi (Heschel's gyrus)

18

short term memory: bilateral or unilateral?

bi (medial temopral lobe)

19

frontal lobe functions (mood, behavior, emotional control, motivation, exec function): bilateral or unilateral?

bi

20

long-term memory: bilateral or unilateral?

diffuse (both)

21

visuospatial function: bilateral or unilateral?

bi. parietal lobe

22

aphasia is lateralized where?

to the dominant hemisphere

23

patients with Broca's, Wernicke's, global and conductive aphasias will be unable to do what?

repeat complex phrases

24

Broca's area infarction results in what?

very reduced speech, repetition and naming. intact aud and visual language comprehension (reading). frustration.

25

Wernicke's area infarction results in what?

output that is active but nonsensical, inability to comprehend language. inability to repeat and name things. not frustrated.

26

conduction aphasia is due to a lesion where?

arcuate fasciculus.

27

define conduction aphasia

reasonably normal expression and comprehension, but impaired repetition of simple and complex phrases.
Inability to repeat due to interruption of the arcuate fasciculus. Fluent, but with paraphasias. Comprehension may be OK.

28

damage to the dominant occipital lobe and splenium of the corpus callosum yields what?

alexia without agraphia. can write but can't read what they're written

29

immediate recall occurs where?

frontal lobe

30

short term memory occurs where?

hippocampus
