[Psychosocial approach to Diogenes syndrome].

Abnormal hoarding of random items in the home associated with severe self-neglect and neglect of one's environment, Diogenes syndrome is transnosographic. It can affect all social classes, people without any diagnosed mental health condition or patients with psychosis or dementia, over 60s and young people. It is conveyed by self-exclusion at home, a "poor precarity" which leads to a loss of the ability to trust others and ask for help.
