Hoarding Disorder

What Is Hoarding Disorder?

Hoarding disorder is a chronic mental health condition officially classified in the Diagnostic and Statistical Manual of Mental Disorders, Fifth Edition (DSM-5). It is defined by a persistent difficulty discarding or parting with possessions, regardless of their actual monetary or sentimental value. This difficulty stems from a perceived need to save items and the distress associated with letting them go.

The accumulation of possessions eventually congests and clutters living areas to the point that their intended use is substantially compromised. In severe cases, rooms become entirely unusable, hallways are blocked, and the home can become a serious health and safety hazard for the occupant and their neighbors.

How Common Is Hoarding Disorder?

Research estimates that hoarding disorder affects approximately 2.5% of the adult population, which translates to roughly 6 to 8 million people in the United States alone. Prevalence increases with age, and the condition is nearly three times as common in adults over 55 compared to younger age groups. In Ohio, this means tens of thousands of households may be affected to varying degrees, from mild clutter to conditions that render a home uninhabitable.

Causes and Risk Factors

The exact causes of hoarding disorder are not fully understood, but research points to a combination of factors:

Genetics: Hoarding tends to run in families. Having a first-degree relative with hoarding behavior significantly increases the risk.
Brain function: Neuroimaging studies have identified differences in decision-making and emotional regulation areas of the brain in individuals with hoarding disorder.
Traumatic life events: Loss of a loved one, divorce, eviction, or financial hardship can trigger or worsen hoarding behaviors.
Co-occurring conditions: Depression, anxiety, ADHD, and PTSD frequently accompany hoarding disorder and can intensify symptoms.
Personality traits: Indecisiveness, perfectionism, avoidance, and difficulty categorizing or organizing possessions are commonly observed.

Relationship to OCD

Hoarding disorder was historically considered a subtype of obsessive-compulsive disorder (OCD). However, the DSM-5 reclassified it as its own distinct condition in 2013. While there is some overlap — both involve repetitive behaviors and anxiety — hoarding disorder has unique neurological patterns and does not respond to the same treatments as OCD in most cases. Only about 20% of individuals with hoarding disorder also meet the diagnostic criteria for OCD, confirming they are related but separate conditions.

Treatment Options

Hoarding disorder is treatable, though progress is often gradual. The most effective approaches include:

Cognitive Behavioral Therapy (CBT): The gold standard for hoarding treatment, CBT helps individuals examine the beliefs driving their hoarding behavior and develop healthier decision-making skills around possessions.
Medication: Selective serotonin reuptake inhibitors (SSRIs) may reduce symptoms in some individuals, particularly when depression or anxiety is a significant factor.
Support groups: Peer-led groups provide accountability and reduce the isolation many people with hoarding disorder experience.
Professional organizing and cleanup: Compassionate, non-judgmental cleanup services can address the physical environment while therapy addresses the underlying condition.

When Professional Cleanup Is Needed

Therapy alone cannot resolve the physical dangers of a hoarding environment. When clutter reaches a level that compromises safety — blocked exits, fire hazards, structural strain, or biohazard conditions — professional hoarding cleanup services become essential. Ohio families often find the best outcomes when cleanup and therapy happen in parallel, with the cleanup team working respectfully alongside the individual's treatment plan.
