Diogenes Syndrome

 The compulsive hoarding of rubbish and seemingly random items is the main feature of Diogenes syndrome which is found mainly in the elderly and is associated with progressive dementia. Other characteristics include extreme self-neglect, apathy, social withdrawal, and a lack of shame.

The syndrome is a misnomer, as it is named after the Greek philosopher Diogenes of Sinope. Diogenes was a Cynic who, according to the philosophy he helped found, rejected the desire for wealth, power, and fame, choosing to live free from all possessions. He found virtue in poverty, slept in a large ceramic jar, and sought social interaction.
