What does Roderick say is wrong with Usher?

I'm thinking that you mean what the narrator said was wrong with Roderick. The narrator describes Roderick as sickly with thin lips and liquid eyes. Roderick pretty much looks like he is going to take face plant and die at any moment. Roderick suffers from mental anxieties (caused by the house or his sister or just being creepy) He can't stand the light or sound. Roderick Usher is in pretty dismal condition.
