1

Define Aphasia

Disorder of language

2

Non fluent aphasia

Broca's

3

Fluent aphasia

Wernicke's

4

what type is conductive aphasia?

Fluent, good comprehension but poor repetition

5

what type is transcortical aphasia?

non fluent, no spontaneous language but good repetition

6

if there is a resection of the corpus callosum visual information of the which visual field cannot be NAMED?

Left visual field (as it is processed by the right cortex)

7

98% of the population have language on their ----- hemisphere

left

8

What artery supplies both broca's and wernicke's area?

Middle Cerebral Artery

9

What division of the MCA supplies Broca's area?

Superior

10

What division of the MCA supplies Wernicke's area?

Inferior

11

What is the arcuate fasciculus?

hypothetical white matter tract linking Broca's and Wernicke's areas

12

Describe Broca's Aphasia?

no fluid sentences, meaning present, content if there.
PATIENT tends to show right face and arm weakness

13

Describe Wernicke's Aphasia?

fluid sentences, no meaning, impaired selection of content, neologism paraphrasic errors. limited or impaired comprehension
PATIENT shows disturbances in visual fields

14

What are the two possible mechanisms to deal with damage to the language centres?

Contralateral Transfer
Ipsilateral Reorganisation

15

Contralateral Transfer happens in the context of

hemispherectomy (recovery only if very young thanks to plasticity)

16

Ipsilateral Reorganisation happens in the context of

due to developmental abnormality/stroke

17

How is better outcome for the patient achieved?

If both happen at both sides:
Contralateral Transfer
Ipsilateral Reorganisation
