Hoarding disorder is characterized by an ongoing resistance to discarding one’s belongings, even those with no value, like junk mail, old newspapers, and materials that most people would consider to be garbage. Hoarders also hold on to personal possessions that they no longer use, either because they feel emotionally attached to these items or because they believe they will need them in the future.

People with this condition may give in to the urge to acquire excessive amounts of objects that fill up their living space. The accumulation of clutter and lack of order and cleanliness can cause health and safety risks within the home, but discarding items may cause the hoarder to feel significant distress. In this way, hoarding disorder can create social, professional, and functional problems that affect not only the individual but also the people around them.


According to DSM-5, the following symptoms are diagnostic of hoarding disorder:

  • There is a persistent difficulty discarding or parting with possessions, regardless of their value or lack thereof.
  • The difficulty in discarding possessions is due to distress associated with getting rid of them.
  • The difficulty in discarding possessions leads to the clutter of living spaces and compromises the use of living spaces.
  • The hoarding creates clinically significant distress or impairment in functioning, including the ability to maintain a safe space.

In some cases, the difficulty in discarding items is accompanied by excessive acquisition of items that are not needed or for which there is no available space.

A hoarder may be completely convinced that the hoarding-related activity—difficulty discarding items, excessive acquisition of items—is not problematic despite evidence to the contrary.

What is the difference between hoarding and collecting?

Unlike a collector, someone who accumulates related objects generally recognized as collectibles with some established value, a person with hoarding disorder gathers up random items and is overly attached to personal possessions that may not have any value whatsoever.

What are signs that I am in the presence of a hoarder?

Hoarders have many items, often in piles or stacks, and most of these items are of little or no objective value. In severe cases, almost every surface in an individual's home, including floors, furniture, counters, and other fixtures, will be covered in piles of clutter, leaving the hoarder only a narrow path clear for walking through the living space, which for the most part is no longer usable.

The cause of hoarding disorder has yet to be identified, although there are known risk factors. People who experience a traumatic event, have difficulty making decisions, or have a family member who hoards are at higher risk of developing the disorder. The majority of people with hoarding disorder also suffer some type of depressive or anxiety disorder.

The tendency to hoard often begins in adolescence and worsens as a person gets older.

Hoarding disorder is viewed as a type of obsessive-compulsive disorder, and many OCD disorders are closely linked to anxiety. None of the symptoms of hoarding disorder is due to any other mental health condition or medical problem. One study found that among the reasons people reported for their hoarding, avoiding waste was the most common.

Is hoarding related to laziness?

No. Laziness and messiness are not related to hoarding, which is a mental health disorder. People who hoard experience great anxiety and distress over their habits and tendencies.

Are hoarding and ADHD related?

ADHD is commonly associated with hoarding, and there is research suggesting that individuals who have ADHD may show an increased risk for hoarding. According to the NIH, some 20 percent of hoarders may meet symptom criteria for ADHD.


Hoarding may persist for a lifetime, but effective treatment can help reduce the need to hold on to unnecessary items; it can also improve decision-making, stress-reducing, and organizational skills.

The primary treatments used to relieve symptoms of hoarding disorder include cognitive-behavioral therapy (CBT) and antidepressant medication, such as selective serotonin reuptake inhibitors (SSRIs). One or the other, or both, may be employed. Early clinical trials suggest that compassion-focused therapy may be more effective than CBT alone.

Can a hoarder be motivated to clean up?

An individual cannot be forced to throw away clutter. Nor will he likely welcome help in discarding his hoarded items. He may well feel his boundaries are being crossed, and that he has the right to live any way he pleases.
