The cause of hoarding disorder is unknown. Although many patients report a family history of hoarding, genetic studies have pointed toward several different genes. Numerous psychological theories concerning the etiology of hoarding disorder point to characteristics often displayed by hoarders, including difficulty initiating and completing tasks, excessive sentimental attachment to possessions, indecisiveness, and impaired memory confidence. In late-onset hoarding, traumatic life events may act as precipitants.
Hoarding disorder has a significantly greater prevalence among males than among females.
