Individuals who experience hoarding related to OCD may have distressing feelings about discarding items. It can drive compulsive saving behaviors that they recognize as excessive.

Obsessive-compulsive disorder (OCD) involves recurring, unwanted thoughts or obsessions that drive repetitive behaviors or mental acts or compulsions, in an attempt to reduce distress. Mental health professionals’ understanding of OCD has changed significantly over time.

The latest edition of the Diagnostic and Statistical Manual (DSM-5) now groups OCD together with hoarding disorder under “Obsessive-compulsive and related disorders (OCRDs).”

Hoarding together with OCD is not an official diagnosis. Instead, it describes when obsessive thoughts and compulsive responses characteristic of OCD primarily drive hoarding behaviors. Hoarding disorder is a separate condition within the OCRD category.

The National Health Service (NHS) in the UK states that hoarding may stem from an underlying condition such as OCD. The DSM-5 reclassified hoarding disorder in 2013, and thus health professionals must correctly assess whether a person’s hoarding issues stems from OCD, or it is hoarding disorder within itself. A person may receive a diagnosis of hoarding disorder if the hoarding has no better explanation by a different mental health condition, such as OCD.

What is OCD?

OCD affects approximately 1 to 3% of the population. It is a mental health condition recognized for recurring, unwanted thoughts or obsessions, and repetitive behaviors or mental acts or compulsions that individuals feel driven to perform. The obsessions cause significant anxiety or distress, while compulsions are attempts to reduce this distress or prevent feared outcomes.

Common OCD themes include contamination fears, concerns about harm or safety, a need for symmetry or order, and forbidden or taboo thoughts. The disorder affects people of all ages and can significantly interfere with daily activities, relationships, and overall functioning when left untreated.

Hoarding OCD presents with several characteristic signs and symptoms:

  • Obsessive thoughts related to possessions: Persistent worries about discarding something important or future need for items. People may fear making the wrong decision when throwing things away.
  • Compulsive saving behaviors: People cannot discard items despite recognizing excess accumulation, and acquire unnecessary items due to obsessive thoughts. They may repeatedly check through discarded items and spend excessive time organizing or reorganizing possessions.
  • Physical environment changes: Individuals accumulate items that compromise living spaces and cause difficulty accessing furniture, appliances, or rooms. Blocked exits can cause safety and fire hazards.
  • Emotional and behavioral indicators: People become significantly distressed when attempting to discard items and avoid cleaning or organizing due to overwhelming feelings. They may experience social isolation due to embarrassment about their living conditions.

People should seek professional help when hoarding behaviors significantly impact daily life, safety, or relationships. They should contact a healthcare professional if they experience:

  • Safety and health risks: Fire hazards, blocked exits, or structural damage from accumulated items that limit access to essential areas like kitchens, bathrooms, or sleeping areas. Additional concerns include pest infestations, mold growth, or other unsanitary conditions threatening physical health.
  • Daily life impact: Interference with work performance, personal relationships, or basic self-care activities. Professional help is also warranted when family members or friends express concern about living conditions, or when individuals experience severe anxiety, depression, or panic attacks related to their possessions.
  • Legal consequences: Receiving eviction notices, housing code violations, or involvement from social services or other authorities due to living conditions.

The development of hoarding OCD involves multiple interconnected factors:

  • Genetic factors: Research suggests hoarding behaviors run in families, with genetic variations affecting brain areas involved in decision making and emotional regulation.
  • Neurobiological factors: Brain imaging reveals differences in areas responsible for decision making and executive functioning, contributing to difficulty discarding items and organizing possessions.
  • Psychological factors: Traumatic experiences, such as significant losses, may trigger hoarding as a coping mechanism. Attachment issues and beliefs about the importance of possessions also contribute to development.
  • Environmental influences: Childhood experiences with poverty, deprivation, or family hoarding increase vulnerability. Stressful life events can trigger or worsen symptoms.
  • Cognitive factors: Thinking patterns like perfectionism, indecisiveness, and excessive beliefs about responsibility maintain hoarding behaviors in OCD.

Diagnosing hoarding OCD requires a comprehensive evaluation by qualified mental health professionals who can distinguish between hoarding disorder and hoarding behaviors driven by OCD.

There is no singular, specific test for hoarding OCD. Therefore, clinicians use various mental health screening tools and standardized assessments to evaluate the severity of OCD symptoms and hoarding behaviors. They assess how these symptoms impact daily functioning, relationships, and living conditions.

Understanding whether the hoarding stems from OCD obsessions or is a separate hoarding disorder is crucial, as it affects treatment planning.

Effective treatment for hoarding OCD typically combines multiple therapeutic approaches:

  • Cognitive behavioral therapy (CBT): CBT can address OCD symptoms and hoarding behaviors. Treatment focuses on challenging obsessive thoughts about possessions, developing decision making skills, and gradually reducing compulsive saving behaviors.
  • Exposure and response prevention (ERP): This evidence-based OCD treatment involves gradual exposure to anxiety-provoking situations such as discarding items while preventing compulsive responses. ERP helps individuals learn to tolerate distress without engaging in hoarding behaviors.
  • Medications: Selective serotonin reuptake inhibitors (SSRIs) are first-line medications for OCD and may help reduce obsessive thoughts and compulsive behaviors related to hoarding.
  • Specialized hoarding interventions: Treatment may include practical skills training for organizing, categorization, and decision making about possessions. Some individuals benefit from in-home sessions where therapists provide support during actual sorting and discarding activities.
  • Family therapy: Including family members in treatment can provide essential support and help address relationship issues that may contribute to or result from hoarding behaviors.

People with hoarding OCD should ask their doctor or a mental health professional to help connect them with appropriate support resources and treatment options.

Individuals can also find support throughthe International OCD Foundation, which offers educational resources, treatment provider directories, and support group information for hoarding-related concerns.

Additionally, the National Alliance on Mental Illness (NAMI) provides education, support groups, and advocacy for people with mental health conditions and their families. NAMI offers local chapters nationwide that host support meetings and educational programs.

Hoarding OCD is a complex condition where obsessive thoughts about possessions drive compulsive saving behaviors that significantly impact individuals’ lives. Unlike hoarding disorder, individuals with hoarding OCD typically recognize the issues with their behaviors but feel trapped by anxiety when trying to discard items.

The condition requires a professional diagnosis to distinguish it from other mental health conditions. Effective treatment may combine cognitive behavioral therapy (CBT), exposure and response prevention, and medication to address obsessive-compulsive symptoms and hoarding behaviors.
