[DC Comics] The Lasso of Truth bypasses mind-wiping, brainwashing, and delusions to find the truth as the subject knows it. However, it can’t make the subject say things they don’t know. With that in mind, how would it work on someone with severe psychosis, or late-stage dementia?

As you said, it bypasses delusions.  


It doesn't provide information, but it removes any barriers keeping them from seeing reality. That includes delusions and dementia- for as long as they are in the lasso, they can see the truth.
