Good, but I'd mention the Tower of Ecthelion rather than the throne room, as that was were Denethor was said to have wrestled with Sauron, and where he began to lose it.

And Denethor was fairly coherent, even to the end. His madness was rather one of pessimism. He believed that there could be no victory against Mordor, and therefore stopped fighting against Sauron and committed suicide. No babbling, but yes, loss of hope.
