Conduction Aphasia

[MudPhud20XX]

So FC explains conduction aphasia as below:

"Conduction aphasia damage to arcuate fasciculus (connection between Wernicke’s and Broca’s area) results in patient’s inability to repeat words but an intact ability to comprehend with fluent speech"

So I get that fluency and comprehension are intact since both Wernicke's and Broca's are fine.

However, how do you explain the inability to repeat words? Why does damage in arcuate fasciculu impairs one's ability to repeat words?

Also, why particular phrases such as "No ifs, ands, or buts?"

this is in wiki. But its a good review. It is untestable as to why for the USMLE because we dont know for sure. if we dont know it aint on it.

The idea is that there is disconnection between monitoring of language. so they get close to what they can say but not exactly. if they have to do it over and over these errors become insurmountable. it may be due to cortical lesioning or arcuate fasciculus...but really its a whole brain issue.

No ifs, ands, or buts is just a standardized phrase that you can have patient's repeat, the key words be standardized--that's how neurologists can validate these tests across different patients. There's nothing magical about that phrase otherwise.
