Diogenes syndrome, also known as senile squalor syndrome or hoarding disorder, is a disorder with extreme self-neglect, hoarding of garbage or animals, domestic squalor, social withdrawal, apathy, and a lack of insight into the problem and the need for help. People with Diogenes syndrome may also display symptoms of catatonia (a lack of movement and a lack of communication, often also with agitation, confusion, and restlessness).
