Hoarding Disorder

Hoarding disorder

Verified by World Mental Healthcare Association

Hoarding disorder (HD) is a mental health condition in which a person experiences a compulsive urge to acquire and accumulate material possessions, along with difficulty in discarding excessive clutter.

What Is Hoarding Disorder?

Hoarding disorder (HD) is a mental disorder 1 characterized by the urge to save and acquire new items, difficulty discarding current possessions, and excessive household clutter. It is popularly considered a subtype of obsessive-compulsive disorder and is also known as compulsive hoarding disorder. However, experts contend that it should be regarded as a separate disorder with its own unique set of symptoms. 

People with this condition display cognitive distortions related to hoarding along with behavior that is often disruptive to their daily life. They are in a constant cycle of acquiring things (regardless of actual value or use) and piling them in living areas; such an enduring behavior pattern can compromise their general hygiene and well-being as well as that of the people around them.

If we take a closer look into the psychology of hoarding, it appears that people with this disorder are likely to derive most of their self-worth from material possessions.

The last two decades have seen a steady rise in the number of hoarding disorder cases. Research affirms that 2–14% 2 of the global population suffers from symptoms of compulsive hoarding.

The overall prevalence 3 of this disorder is higher in men (than women) 1, the elderly population, and people with certain psychiatric disorders (like obsessive-compulsive disorder, stress disorders, etc.). However, the personal nature of hoarding and the stigma attached to mental healthcare treatment prevents people from seeking medical attention.

Hoarding vs Collecting

Case Example

Mr. Shetty (a 60-year-old man) was in the habit of storing unnecessary things such as newspapers and magazines dating back years, empty containers of toiletries, and old worn-out clothes and accessories.

Although his hoard had become more visible over the years, it seemed that he had been “collecting” things for decades. His garage was overflowing with spare parts of cars he didn’t have anymore and cartons full of numerous cords, defunct phones, old gadgets, and a bunch of other unusable items.

He got quite upset when his son or daughter cleared up his stuff. Sometimes, this would trigger him to hoard more things in rebellion. He seemed to derive a sense of comfort from all of his objects; “These are marks of my existence,” he would say. “They are proof that I have lived a worthy life.” He certainly did not believe that he may have a problem.

Mr. Shetty’s hoarding behavior had begun a few months after the death of his father, about 25 years ago. Since then, he was obsessed with holding on to material possessions, afraid that there would be nothing to show for him when he left the world.

Case Analysis

It is evident from the excerpt above that Mr. Shetty was experiencing difficulty in parting with his possessions and had been accumulating excess things that would clutter his living area.

These symptoms present a classic case of hoarding disorder with a lack of insight. Mr. Shetty’s sense of identity was indubitably linked to everything he had ever owned.

2. Neurocognition

Premature cognitive aging and executive dysfunction, among other cognitive domains are linked to the risk of hoarding disorder.

3. Personality traits
