Hoarding disorder is something that many people have become familiar with through reality TV shows, but the real-life impact of this condition goes much deeper than what we see on screen.

It’s not just about being messy or holding onto too many things; it’s a serious mental health issue that affects a person’s daily life. So, what exactly is hoarding disorder, and why do some people develop it?

Let’s take a closer look.

What is Hoarding Disorder?

Hoarding disorder happens when someone finds it extremely difficult to part with their possessions, even items that may seem small, worthless, or unnecessary to others. This isn’t the same as collecting, where people carefully choose and display items in an organized way.

For those with hoarding disorder, the items pile up, often in a disorganized manner, and start to interfere with basic activities like moving around the house, cooking, or cleaning. Over time, this can seriously affect their quality of life.

What Causes Hoarding Disorder?

There’s no single cause of hoarding disorder, but researchers believe it’s likely caused by a combination of genetic factors, brain differences, and life experiences. Let’s break these down.

Genetics: A Family Connection

Hoarding disorder often runs in families, suggesting that genetics might play a role. A 2014 study in the American Journal of Psychiatry found that people with close relatives who have hoarding disorder are more likely to develop the condition themselves.

However, genetics isn’t the only factor. Just because someone has family members with hoarding disorder doesn’t mean they will automatically develop it. It’s similar to how having a family history of certain illnesses, like heart disease, increases your risk but doesn’t guarantee it.

Brain Differences: How the Mind Processes Stuff

People with hoarding disorder seem to think and feel differently about their possessions compared to others.

Brain imaging studies have shown that certain areas of the brain, especially those involved in decision-making and emotional regulation, become highly active when people with hoarding disorder are asked to throw things away.

A 2013 study published in Archives of General Psychiatry found that hoarders struggle with decision-making and organizing their belongings.

For them, getting rid of things can be extremely stressful and anxiety-provoking, which makes it harder to keep their living spaces clean and organized.

Life Experiences: The Role of Trauma

For some people, life events can trigger hoarding behavior. Traumatic experiences like the loss of a loved one, a divorce, or financial hardship may lead someone to hoard as a way to cope with difficult emotions. In these cases, possessions provide a sense of comfort and safety, almost like an emotional shield.

Additionally, people who grow up in cluttered or chaotic homes may be more likely to develop hoarding disorder later in life. A 2011 study published in The Journal of Clinical Psychiatry found that people exposed to hoarding behavior during childhood were more prone to developing similar habits as adults.

Putting the Pieces Together

Hoarding disorder is complicated. It’s not just about being overly attached to things or lacking organizational skills. Instead, it involves a combination of genetic predisposition, differences in how the brain works, and personal experiences.

Understanding the causes of hoarding disorder is like solving a puzzle—each piece, whether it’s genetic, brain-related, or environmental, contributes to the bigger picture.

While there is still much to learn about why people develop hoarding disorder, researchers are making progress. The more we uncover about the condition, the better we can develop treatments to help those who struggle with it.

Getting Help

If you or someone you know is dealing with hoarding disorder, reaching out to a mental health professional is a great first step.

Therapy can help people with hoarding disorder manage their behavior, make decisions about their possessions, and reduce the anxiety they feel when letting things go. Remember, seeking help is a sign of strength, and there are strategies and support systems available to make life easier for those affected by hoarding disorder.
