Word salad and echolalia appear to be the preferred speech patterns
These are symptoms of Schizophrenia which are related to disorganized speech and this client is an example of that.
He is making up words like "keg" and "hoopanize";
He doesn't form sentences that make sense(word salad), in a moment is talking about eggs and the other about kicking a leg;
He is rhyming a lot (eggs, meg, keg, leg...) and it's repeating the same sound(echolalia).
