Hoarding disorder — structured clinical viva

This is severe hoarding disorder with excessive acquisition phenotype likely, animal-hoarding features, and environmental emergency risk (blocked exit). Fair-to-poor insight is common and does not convert the case into schizophrenia by default. Animal welfare and fire safety sit alongside psychiatric care — not after it.[1][2][6]

Diagnosis and differential

State DSM-5-TR OCRD criteria for HD: difficulty discarding, clutter compromising living areas, distress/impairment, exclusions. Discriminate OCD-related saving (contamination/harm/symmetry logic), squalor (filth/self-neglect cluster — may coexist), ADHD executive clutter, and organic late-onset if cognitive red flags appear. Animal accumulation with inadequate care is animal hoarding — welfare reporting is mandatory teaching, not optional kindness.[1][2][6]

Risk hierarchy

1. Life safety: clear egress, fire load, smoke alarms, medical squalor complications.
2. Dependent humans if any; animal welfare.
3. Housing/eviction trajectory and carer burden.
4. Mood/suicidality comorbidity.
   Harm-reduction can start immediately while engagement for CBT builds.[2][6][7]

Capacity

Decision-specific: he may retain capacity for some choices (accepting fire-officer pathway clearance) and lack it for others. Assess understanding, appreciation, reasoning, communication for each decision. Guardianship/adult safeguarding pathways are jurisdiction-specific; least restrictive options first.[2][6]

Treatment

Specialised CBT for HD: skills, graded discarding, non-acquisition, cognitive work, home sessions — supported by waitlist RCT and meta-analysis.[3][4] Medication: treat depression/ADHD/OCD as indicated; cite open-label paroxetine (and venlafaxine XR) as limited adjunctive signals — not OCD-level certainty.[5]

Forced cleanout demand

Empathise with family burden. Explain that surprise total cleanout without therapy often causes reaccumulation and rupture. Prefer collaborative partial clearance of high-risk zones, fire service partnership, and simultaneous CBT engagement. Emergency clearance if imminent life threat, with a follow-up care plan locked in.[2][3][7]
