HOARDING DISORDER

SCF-RDOS INDICATION REGISTRY ENTRY

Classification

DEFINITION

HOARDING DISORDER is a condition characterized by persistent difficulty discarding or parting with possessions regardless of their actual value, resulting in excessive accumulation of items that congest living areas and substantially impair functioning, safety, health, or quality of life.

The core pathology is not simply collecting or saving objects. Rather, individuals experience intense distress associated with discarding possessions, excessive perceived need to save items, emotional attachment to objects, fear of losing important information or opportunities, and significant impairment in decision-making related to acquisition and disposal.

Within the SCF-RDOS framework, Hoarding Disorder is conceptualized as a possession-valuation and executive-regulation disorder involving dysfunction across decision-making systems, emotional-attachment networks, risk-evaluation pathways, executive-control mechanisms, ownership-processing circuits, and behavioral-organization architecture.

ETIOPATHOGENIC CORE

Primary Pathogenic Theme

Distorted valuation of possessions combined with impaired decision-making and excessive emotional attachment to objects leads to progressive accumulation, environmental clutter, and functional impairment.
