<unk> , also known as senile squalor syndrome, is a disorder characterized by extreme self-neglect, domestic squalor, social withdrawal, apathy, compulsive hoarding of garbage or animals, plus lack of shame. Sufferers may also display symptoms of catatonia. The condition was first recognized in 1966 and designated<unk>  by Clark et al. The name derives from<unk>  of Sinope, an ancient Greek philosopher, a Cynic and an ultimate minimalist, who allegedly lived in a large jar in Athens. Not only did he not hoard, but he actually sought human company by venturing daily to the Agora. Therefore, this eponym is considered to be a misnomer. Other possible terms are senile breakdown, Plyushkin's Syndrome (after the Gogol character), social breakdown and senile squalor syndrome. Frontal lobe impairment may play a part in the causation (Orrell et al., 1989).
