asphasia

Question 1

Wernicke’s aphasia presentation

Answer 1

receptive

“word salad” - sentences that make no sense, speech remain fluent

Question 2

wernickes asphasia anatomy

Answer 2

superior temporal gyrus

-> supplied by inferior division of left MCA

wernickes area forms speech before sending to brocas area

Question 3

Broca’s asphasia presentation

Answer 3

expressive

speech is non-fluent, laboured + halting
- repetition is impaired

Question 4

brocas aphasia anatomy

Answer 4

lesion of the inferior frontalgyrus
- > supplied by superior division of left MCA

Question 5

comprehension in wernickes vs brocas aphasia

Answer 5

wernickes = impaired comprehension

brocas = normal comprehension

conduction = normal comprehension

Question 6

wernickes - expressive or receptivee?

Answer 6

wernickes = receptive

brocas = expressive (makes sense)

Question 7

conduction asphasia

Answer 7

classically due to a stroke affecting arcuate fasiculus
–> the connection between Wernickes + Brocas area

Question 8

conduction asphasia presentation

Answer 8

speech is fluent but repition is poor
- aware of errors they are making

comprehension = normal

Question 9

global asphasia

Answer 9

large lesion affecting all 3 areas
- wernickes
- brocas
- arcuate fasiculus

can only communicate with gestures

Question 10

if speech is fluent (but not making sense) how do you distinguish between diagnoses

Answer 10

is comprehension intact?

intact = conduction (arcuate fasiculus)

impaired = wernickes

Question 11

if speech is non-fluent (laboured, halting) how do you distinguish between diagnoses

Answer 11

is comprehension intact?

intact = broca’s

impaired = global asphasia!
