 And it is common practice amongst neurologists to say if those things are fine, there's no reason for cognitive testing. But when a situation shows itself that says, hmm, that looks bad, there's two ways you can do it. You can go back and start with the MRIs and the spinals and everything else, or you can take a cognitive test, which then would ask, and if something came up, you know, like, oh boy, he's missing something here, then you go back to the testing. And he does not want to open that door.
