Clinical Vignette
Patient: "Mrs. C," 63-year-old retired postal worker, referred by adult protective services after a concerned neighbor reported that her home may be uninhabitable due to accumulated possessions.
Chief Concern: "There's nothing wrong with my home. I know where everything is. These are useful things that I might need someday. My neighbor has no right to call anyone — my things are MY business."
History of Present Illness: Mrs. C lives alone in a 3-bedroom home that she has owned for 30 years. APS investigation found every room stacked floor-to-ceiling with newspapers, magazines, empty containers, clothing, old mail, and miscellaneous household items. Only a narrow pathway exists from the front door to the kitchen and bathroom. Two bedrooms and the dining room are inaccessible. The kitchen stove and oven are unusable (covered in stacked items). She sleeps in a recliner because her bed is buried under possessions. The accumulation has progressed over 15 years, accelerating after her husband's death 8 years ago. She purchases 10-15 items weekly from thrift stores ('they might be useful'), saves all newspapers and junk mail ('I might read them'), and keeps all packaging ('the boxes are perfectly good'). She becomes acutely distressed at any suggestion of discarding items, describing 'a physical pain in my chest' at the thought of throwing anything away. She has declined help from her children, who have offered to clean. Fire department has cited the home as a fire hazard.
Past Psychiatric History: No prior psychiatric treatment. No prior OCD or anxiety symptoms beyond hoarding.
Family History: Father was 'a pack rat' (never diagnosed). No other psychiatric history.
Mental Status Exam: Cooperative but defensive about possessions. Speech organized. Mood 'fine — I just want to be left alone.' Affect becomes anxious and irritable when discarding is discussed. No psychotic symptoms. No depression. Insight poor: does not perceive the living situation as problematic. Judgment impaired regarding safety hazards.
Step 1: Hoarding Disorder DSM-5-TR Criteria
Criterion A: Persistent difficulty discarding or parting with possessions, regardless of their actual value.
Cannot discard newspapers, junk mail, empty containers, old clothing. Difficulty applies to items of no objective value. Physical distress when discarding is suggested. MET.
Criterion B: This difficulty is due to a perceived need to save the items and to distress associated with discarding them.
Saves items because 'I might need them' (perceived future utility). Experiences 'physical pain in my chest' when discarding is suggested (distress). Not due to indifference or laziness. MET.
Criterion C: The difficulty results in accumulation of possessions that congest and clutter active living areas and substantially compromise their intended use.
All rooms congested. 2 bedrooms and dining room inaccessible. Kitchen stove/oven unusable. Sleeps in recliner. Fire hazard citation. MET — SEVERE.
Criterion D: Clinically significant distress or impairment in functioning.
Home is a fire hazard. Cannot use essential areas (kitchen, bedrooms). Social isolation (embarrassment about home prevents visitors). APS involvement. MET.
Criterion E: Not attributable to another medical condition.
No dementia. No traumatic brain injury. Cognition intact. MET.
Criterion F: Not better explained by another mental disorder.
No OCD (no intrusive thoughts or rituals beyond saving). No depression (hoarding is not due to apathy). No psychosis. MET.
Step 2: Specifiers and Differential from OCD
| Feature | Hoarding Disorder | OCD (Hoarding Symptoms) | Collecting | This Patient |
|---|---|---|---|---|
| Motivation to save | Perceived utility, sentimental value, aesthetic value | To prevent feared consequence (contamination, harm) | Specific category, organized display | HD: 'might need them someday' |
| Distress about saving | Distress about DISCARDING only | Distress from intrusive OBSESSIONS | No distress about having or discarding | HD: distress only at discarding |
| Organization | Disorganized accumulation | May be organized (ritual-driven) | Carefully organized and displayed | HD: disorganized stacks |
| Ego-syntonic/dystonic | Ego-syntonic (values the possessions) | Ego-dystonic (unwanted urge to hoard) | Ego-syntonic (hobby) | HD: values possessions, defensive about them |
| Insight | Often poor | Usually good | Full insight | HD: poor insight — does not see the problem |
Specifiers
Insight specifier: Poor insight (does not perceive the living situation as problematic despite fire hazard citation and APS involvement). Acquisition specifier: With excessive acquisition (purchases 10-15 thrift store items weekly).
Diagnostic Formulation
Diagnostic Conclusion
Hoarding Disorder, with Excessive Acquisition, with Poor Insight (F42.3): All 6 DSM-5-TR criteria met. Fifteen-year progressive accumulation. Home uninhabitable (fire hazard, inaccessible rooms, unusable kitchen). Poor insight specifier. Excessive acquisition specifier. Treatment: CBT for hoarding (specialized protocol: sorting, discarding practice, cognitive restructuring of beliefs about possessions, acquisition reduction). SSRI may augment CBT. Treatment is complicated by poor insight and resistance.
Teaching Points
- Hoarding Disorder was separated from OCD in DSM-5 as an independent diagnosis. The neurobiological profiles differ: hoarding involves different brain circuits (anterior cingulate, insular cortex) than OCD (cortico-striato-thalamic loop), and hoarding responds poorly to standard OCD treatments.
- The excessive acquisition specifier is clinically important because treatment must address both the difficulty discarding AND the ongoing acquisition. Reducing inflow (curbing shopping, thrift store visits, free item accumulation) is as important as increasing outflow (discarding).
- Hoarding Disorder has significant public health implications: fire hazards, pest infestation, structural damage, unsanitary conditions, and fall risks. APS involvement and compulsory cleanouts are common but counterproductive without simultaneous psychiatric treatment: forced cleanouts reliably produce acute distress and are typically followed by re-accumulation.
- CBT for hoarding is a specialized protocol distinct from standard CBT or ERP. It includes: motivational interviewing (addressing ambivalence about change), cognitive restructuring (challenging beliefs about possessions), sorting/discarding practice (graduated exposure), and acquisition reduction (developing rules for purchasing).
- Poor insight in Hoarding Disorder is common and represents a significant treatment barrier. Unlike OCD (where most patients recognize their symptoms as excessive), many individuals with Hoarding Disorder genuinely do not perceive a problem. Motivational interviewing techniques are essential to build treatment engagement.
