Hoarding disorder involves the accumulation of things coupled with an inability to part from possessions to the point that an individual’s living space is no longer functional and has become hazardous. Assorted belongings, clutter and trash pile up on tables, countertops, furniture, and beds. Stoves, sinks, bathtubs, and even toilets may become unusable. Movement might be restricted to narrow pathways through piles on the floors. In some cases, multiple animals are involved. Fecal matter, mold, and rodents may be ignored by the individual with a hoarding disorder. People can lose housing and important relationships because of their hoarding behaviors but they either cannot stop the behavior or have little to no insight to the risks and consequences of their behavior. Hoarding disorder is a disturbing condition that may look like self-neglect because the individual who is hoarding does so at their own peril. Approximately 75% of individuals with hoarding disorder also have an anxiety or mood disorder. It is not considered a hoarding disorder if the situation is caused by a neurocognitive disorder such as dementia.
