Bizarre Humor a Symptom?

"Developing a bizarre sense of humor is an early sign of dementia." Health News

Interesting!  Especially, according to this online article, if the humor is slap stick.  My loved one did seem to develop more and more a slap stick sense of humor, but I am not sure if he always had that.  It was, at least, more pronounced before the dementia got him in its clutches and destroyed all sense of humor.  The reason for considering symptoms besides loss of memory is that we can diagnose dementia earlier and perhaps stall its progression longer.
