I got the impression that he deeply believed everything he said...which I could tell about twenty minutes into the debate that he was telling you things that just weren’t truthful or factual.

One thing which is typical for people with incipient and moderate dementia is the covering of memory loss by confabulation. Confabulation means essentially that the person fills in the blank spots in his defective memory with made up "facts" and "memories." It is common in late stage alcoholism as well as other forms of progressive dementia.
