Hoarding disorder is characterised by a significant accumulation of possessions, accompanied by extreme difficulty in discarding these possessions. This can result in significant impairment to the person’s daily life, such as not being able to bathe or cook at home or not being able to sleep in a bed.
The possessions accumulated can be any type of object. Often, people accumulate large quantities of papers/paperwork/books, clothes, recycling (e.g., empty containers), items that remind them of other people or times in their life, or items they intend to repair or sell. For someone suffering hoarding disorder it is very distressing to discard such items.
Hoarding disorder is estimated to affect 2-5% of the population. People are sometimes reluctant to ask for help as they fear that their possessions will be forcibly removed or that they will face legal proceedings or eviction. People are often ashamed and are isolated from family and friends.
People with hoarding problems often have other psychological difficulties, such as social anxiety and/or depression, and physical health problems, such as fibromyalgia or diabetes.
Hoarding disorder was diagnosed as part of Obsessive Compulsive Disorder (OCD) or Obsessive Compulsive Personality Disorder (OCPD) until 2013 when it was reclassified as a separate problem.
