1

what is aphasia?

disturbance in language as a results of brain damage

2

language versus speech

language produced via:
1. speech
2. writing

3

3 causes of aphasia:

1. acute:stroke
2. insidious: dementia
3. paroxysmal: seizures/migraines

4

Paul Broca started the move towards?

lateralization

5

% of ppl who are left lateralized?

95% right handers
70% left handers

6

does right hemisphere have any role in language?

Yes.
Prosody
paralinguistic aspects

7

2 divisions of MCA?

superior
inferior

8

inferior MCA supplies?

1. temporoparietal cortex
2. visual tracts

9

superior MCA supplies?

1. sensorimotor cortex
2. ventrolateral prefrontal cortex

10

2 parts of language system is?

1. production
2. selection

11

Non fluent aphasia is problem with? what kind of lesion?

anterior lesion:
prob with production/grammar/structure

12

Broca's aphasia called?

non-fluent aphasia

13

Wernicke's aphasia called?

fluent aphasia

14

fluent aphasia is impaired where? with what?

posterior lesion
impaired selection of content

15

2 areas of in Broca important in language: Pars...

1. pars triangularis
2. pars opercularis

16

2 gyri that have temporoparietal assication neocortex with Wernicke's area?

1. supramarginal gyrus
2. anglar gyrus

17

what is the arcuate fasciculus tract for?

link Wernicke's to premotor and Broca's

18

Wernicke's aphasia language output include what 2 things?

1. neologisms
2. paraphasic errors

19

Wernicke's aphasia motor and comprehension is?

no motor impairment
impaired comprehension

20

what happens if you get Wernicke's aphasia affecting visual tracts?

could have right quadrantanopsia

21

Broca's Aphasia: describe

Non-fuent
highly effortful speech

22

Broca's Aphasia comprehension and muscles?

preserved comprehension
right face and arm weakness

23

What is conduction aphasia?

fluent aphasia better thn Wernicke's
poor repetition of words

24

what is transcortical motor aphasia?

non-fluent
repetition is preserved
muteness if severe.

25

2 big mechanisms of recovery:

1. contralateral transfer
2. ipsilateral re-organization

26

examples of contralateral transfer?

young age:
1. stroke
2. hemispherectomy

27

examples of ipsilateral reorganization? when?

adults
1. stroke
2. focal developmental anomaly

28

which is better long term recovery? reorganization ipsilateral? or contralateral?

both is best

29

Uvula towards or away from lesion?

away from lesion

30

sticking out tongue: is weak side towards or away from lesion?

towards lesion
