What is the question asking? Why do you have Aphasia? I'm not sure what the relationship here is. Or are you suggesting you're good at math but not good at language?

I feel weird answering even if I infer the right question because it feels tautological. If you have Wernicke's Aphasia does it not create the possibility that I already have but your condition resulted in misunderstanding. Given the condition does it not create a high probability that a response will similarly be misunderstood? Is not Anosognosia quite common?

Maybe I'm really misunderstanding but honestly I'm not sure what you're asking
