Flashcards in W21-L10: Disorders of Language Deck (13):
1

Aphasia

A disturbance in language as a result of brain damage

2

Describe the Hemispheric dominance

Right hemisphere for visuospatial function and left hemisphere for language

3

What does the superior division of the middle cerebral artery supply?

-Sensorimotor cortex
-Ventrolateral prefrontal cortex

4

What does the inferior division of the middle cerebral artery supply?

-Temporoparietal cortex
-Visual tracts

5

What are characteristics of non-fluent aphasia and what is it called?

-Anterior lesion
-Loss of grammatical (sequential) structure
-Intact selection of content
-Broca’s aphasia

6

What are characteristics of fluent aphasia and what is it called?

-Posterior lesion
-Impaired selection of content
-Intact grammatical (sequential) structure
-Wernicke’s aphasia

7

What is the Arcuate Fasciculus?

A hypothetical white matter tract that connects areas of language together (Broca's and Wernicke's)

8

What are the symptoms of the syndrome of wernicke's aphasia?

-Fluent jargonistic language output
-Impaired comprehension
-Right quadrantanopsia
-No motor weakness

9

What are the symptoms of the syndrome of Broca's aphasia?

-Non-fluent, highly effortful language output
-Telegrammatic
-Preserved comprehension
-Right face and arm weakness

10

What is conduction aphasia?

-Fluent aphasia, but more meaningful than Wernicke’s type
-Relatively intact basic auditory comprehension
-Poor repetition of words

11

What is the suspected lesion that causes conduction aphasia?

Lesion of the arcuate fasiculus tract

12

What is transcortical motor aphasia?

-Non-fluent aphasia
-Muteness at most severe
-Repetition is preserved

13

What are some mechanisms of recovery to aphasias?

-Contralateral transfer
-Ipsilateral re-organization
-reorganising into two hemispheres is better than reorganising into one
