What Is Diogenes Syndrome? Hint: Geriatrics Question

Diogenes syndrome is a behavioral disorder of the elderly. It was first defined by a study published in The Lancet in 1975: "acute illness and extreme self-neglect, patients lived in dirty, untidy homes and had a filthy personal appearance about which they showed no shame. An acute presentation with falls or collapse was common."

The name of the syndrome comes from the Greek philosopher Diogenes who believed in self-control and simple living. I am still not completely sure how the syndrome description and the philosopher are connected...

Diogenes once wandered through the streets of Athens with a torch in full daylight, searching for an honest man.

When Alexander the Great met Diogenes, he asked if there was any favor he might do for him. Diogenes replied, "“Move a little, you a’re standing in my sun." Alexander still declared, "If I were not Alexander, I would be Diogenes." (Wikipedia)

I just added a short description of the syndrome to the Wikipedia article about Diogenes. You can also help to make the largest encyclopedia in the world better.
