When a person is born deaf, what language do they think in?

I know they eventually learn how to read and understand other human beings, but what happens until then/what would happen if they simply never did?

To elaborate even further on the first two responses.  People think in pictures, mental images.  We don't begin to assign words to those images until we learn language.  People also have basic needs such as food and water.  In that case we are not thinking in images but rather based on instinct.  We then assign words to those needs.
