Hoarding disorder is a psychological disorder that may present on its own, or as a symptom of another disorder such as obsessive-compulsive personality disorder (OCPD), obsessive-compulsive disorder (OCD), attention-deficit/hyperactivity disorder (ADHD) and depression. Hoarding disorder is defined by a chronic difficulty discarding or parting with possessions because of a perceived need to save them, regardless of their value. Hoarding manifests itself as the patient accumulates a large amount of what most people would consider junk, and has a tremendous impact on health quality of life.
