Hoarding disorder, also known as disposophobia, is a mental health disorder defined by the excessive accumulation and reluctance to dispose of possessions. Other synonyms for hoarding disorder are cluttering, squaloring, and pack-ratting. It is a serious condition that can lead to dangerous living conditions, physical health issues, and social isolation. Hoarding disorder is not the same as collecting or being disorganized. It is a distinct disorder that requires professional intervention and support. Hoarders may need to work with mental health professionals, organizers, and support groups to combat the disorder and improve their quality of life.
