I need help with my brother

Hey guys, I’ll go straight to the point. I think my brother is schizotypal or has some other disorder in this spectrum. He denies it, won’t see a doctor, and believes that he knows things others don’t know, being the “normal” or even “gifted” one, while all others are just “blind and dumb”.
Those who have this condition, how did you know? When did you realize? Did you do something about it? Is it possible that he really has no idea that he’s sick?
I wonder how could I help him, but I’m out of ideas and he keeps denying it, getting defensive and we always end up in loud arguments about some nonsense, for example conspiracy theories or the “the doomsday is coming” talk.
He can’t live a normal life, because what’s the point of even trying when the world will surely end soon (he’s predicting it every time we speak for about 8 years now…)
