It depends on your family history.
If your brother is currently hearing, then it's likely that he won't become deaf later in life... unless you have a family history of it happening.
I was born hearing. I became deaf because of neglect. If I had a kid, it would likely be hearing.
I got sick. I wasn't given proper medical attention. I became deaf.Ahh how come?? How did you became deaf because of neglect what?? Do you mean an ear infection?
