Which disorder involves persistent difficulty discarding possessions?

Hoarding Disorder is characterized by a persistent difficulty in discarding or parting with possessions, regardless of their actual value. This behavior is typically driven by a strong emotional attachment to the items, feelings of anxiety about getting rid of them, or beliefs that they might be needed in the future. Individuals with hoarding disorder often accumulate excessive amounts of items, leading to clutter that disrupts their living spaces and significantly impacts their quality of life.

In contrast, Body Dysmorphic Disorder involves preoccupation with perceived flaws in physical appearance, Trichotillomania refers to the compulsive urge to pull out one’s hair, and Excoriation Disorder is the compulsive picking at skin. While these conditions involve compulsive behaviors, none of them specifically pertain to the inability or difficulty in discarding possessions, which is the hallmark feature of Hoarding Disorder.
