3

What is the difference between literal and verbal paraphasias?

Verbal: word substitution
Literal: sound substitution

4

What are the components of auditory comprehension?

Single words

7

What are the symptoms of conduction aphasia?

Fluent speech

poor naming
poor repetition

8

What is conduction aphasia due to?

possibly a lesion in the arcuate fasiculus

9

What are the symptoms of wernicke's aphasia?

Fluent speech
Poor comprehension
Poor repetition

Can't point to the door, but when asked to go to the door (whole body command), he did it

10

What causes wernicke's aphasia?

Lesion in the posterior temporal lobe

Poor naming

22

What causes anomic aphasia?

Temporo/temporo-parietal lesion

23

How does alexia without agraphia occur?

Lesion that damages left occipital + posterior part of corpus collosum
Info has to get to angular gyrus from either occipital lobe, but in this case, it doesn't
