Obsessive Compulsive Disorder Treatment and Symptoms

Different Types of OCD

What Type of Disorder Is OCD?

Obsessive-Compulsive Disorder (OCD) is classified as an anxiety disorder.

People with Obsessive-Compulsive Disorder (OCD) experience distressing, unwanted thoughts that drive them to perform repetitive and ritualistic actions to reduce the anxiety triggered by these thoughts.

Are There Different Types of OCD?

OCD is a very complex disorder that can manifest itself in various ways. There are different types of OCD, but some people may not fall into just one category.

It’s important to note that while the specific obsessions and compulsions may vary, the underlying mechanism of anxiety and obsession-driven behaviors is in all types.


How Many Types of OCD Are There?

OCD generally falls into four different categories, but some people categorize it into 7 or even 13 different categories.

Categories range from common OCD themes such as contamination OCD, which often leads to cleaning compulsively, to more specific themes such as scrupulosity, which centers around moral and religious obsessions.

Some types manifest differently than others. For example, “Pure O” OCD is centered almost entirely on mental obsessions, and less on behaviors.


What Are the Different Types of OCD?

The four most common types of obsessive-compulsive disorder include cleaning/contamination OCD, order/symmetry OCD, harm OCD, and hoarding OCD.

Types of OCD_02 4 Common Types of OCD

Here is a more thorough breakdown of these four types and how they appear in daily life:

  1. Cleaning/Contamination OCD
    This type involves obsessive fears of germs, dirt, or contamination, which lead individuals to engage in compulsive cleaning or avoidance behaviors.
  2. Order/Symmetry OCD
    People with this subtype have obsessions related to achieving perfection, symmetry, or exactness. Compulsions often involve arranging and organizing items to meet these standards.
  3. Harm OCD
    Individuals with harm OCD experience distressing thoughts or fears about causing harm to themselves or others. Compulsions may include checking behaviors to make sure nothing bad has happened.
  4. Hoarding OCD
    Hoarding involves difficulty discarding possessions, even when they have no practical value. This can lead to excessive clutter and a reluctance to part with items.


What Is the Most Common Type of OCD?

Contamination OCD is the most commonly seen subtype of OCD.


Can You Have Multiple Types of OCD?

Yes, OCD is a complex disorder, and individuals with OCD may experience symptoms that don’t fall under simply one type of OCD.

Many people with OCD experience symptoms of multiple types of OCD. They also often experience related disorders and mental illnesses that can make it difficult to pin down a diagnosis at first.

What Part of the Brain Is Triggered by OCD?

Studies suggest that the prefrontal cortex, basal ganglia, and thalamus are all triggered by OCD.

Contamination OCD with Washing/Cleaning Compulsions

What Is Contamination OCD?

Contamination OCD is a type of OCD that involves the fear of contamination, contaminating others, or spreading germs.

People who have Contamination OCD often have very upsetting thoughts about germs or dirt, even in situations that most people wouldn’t worry about. These thoughts make them feel extremely anxious and uncomfortable.

Obsessions and compulsions may include:

Obsessions: Fear of germs, dirt, or other contaminants.

Compulsions: Excessive hand-washing, showering, or cleaning objects.


What Causes Contamination OCD?

The causes of OCD, including contamination OCD, are unknown. However, factors like brain chemistry, genetics, and learned experiences may play a role.

Types of OCD_03 Factors in OCD Inline Image

How to Beat Contamination OCD?

One of the most common treatment approaches for contamination OCD is exposure and response prevention (ERP) therapy.

In ERP therapy, an individual with contamination OCD gradually faces their fears. Then, they will actively try not to engage in their compulsion.

For example, a person who is nervous about the contamination of a doorknob may gradually try to touch it without washing their hands immediately after. As they get better, they will be able to delay the time between touching the doorknob and washing their hands to help loosen the power of their compulsion.


How to Treat Contamination OCD at Home?

If a person is diagnosed with contamination OCD, it is best to receive professional help and not try to treat yourself.

However, there are things a person can do outside of therapy that may help them manage symptoms and triggers of contamination OCD.

Managing stress and practicing healthy habits such as getting physical exercise, eating a balanced diet, and getting good rest can help a person minimize triggers and ruminations that worsen the symptoms of OCD.

How to Help Someone With Contamination OCD?

If a loved one may have contamination OCD, it is best to connect with professional help to get a proper diagnosis and guidance on how you can help them.

Going through therapy for contamination OCD can be challenging in everyday life, and having someone there who encourages and supports them can make all the difference. You can also attend support groups with them so that they can build a network of people who understand what they’re going through.

Checking OCD

What Is Checking OCD?

Checking OCD is a form of OCD that involves checking and rechecking things to feel less afraid that something bad will happen.

These rituals are used to reduce feelings of uncertainty that can feel unbearable.

Some obsessions and compulsions with this type may include:

Obsessions: Fear of something bad happening, experiencing intrusive thoughts that they are not doing something that prevents harm, fear that they lost something.

Compulsions: Repetitively checking if they turned off appliances, repeatedly making sure things are locked, closely inspecting things.

Types of OCD_05 Common Cmpulsions for Checking OCD Inline Image

What Triggers Checking OCD?

Everyone’s triggers can be different. However checking OCD is often triggered by a fear that something bad will happen to themselves or another person if they don’t check and recheck what they are worried about.

Some triggers may include fearing that they accidentally left the oven on or forgot to change the batteries in the smoke detector.


What Does OCD Checking Feel Like?

A person with OCD checking may often feel anxious, worried, or stressed that something terrible is going to happen if they don’t engage in their compulsions.

These ruminations can feel inescapable, which can make the sufferer isolate themselves from other people. They also may experience intrusive thoughts and different symptoms of anxiety.

Types of OCD_06 Rumination Thought Processing Inline Image

Why Is OCD Checking Bad?

OCD checking is unhelpful because it impacts a person’s ability to function in daily life, which can destroy their confidence.

OCD checking also leads to more compulsive behaviors that can take up a lot of a person’s life energy. This can also make it difficult for them to have healthy social lives and careers if their checking compulsions are severe.


How Do You Stop OCD Checking?

Cognitive behavioral therapy (CBT), like exposure and response prevention therapy, can help a person learn to challenge their thoughts and not give in to their compulsions.

Speaking to a professional in the psychiatry and psychology field can help them to find the specific resources they need to break the cycle of obsessive and compulsive checking.


Is Checking OCD Curable?

OCD is not curable, but it is treatable.

Obsessive-Compulsive Disorder (OCD) is considered a chronic condition, which means that it typically does not have a complete “cure.” However, with appropriate treatment, many individuals with OCD can significantly reduce their symptoms, manage the condition effectively, and lead fulfilling lives.

Types of OCD_07 What OCD Treatment Can Do Inline Image

Does OCD Go Away if You Ignore It?

OCD does not just go away on its own. Often by trying to ignore OCD, obsessions can become stronger, which can cause a cycle of distress and worsening symptoms.

OCD is a mental health condition that almost always requires professional treatment.

How Common Is Harm OCD?

Sometimes people with harm OCD are embarrassed or afraid to tell others about their experiences, so it is also likely underreported.

The four most common types of OCD include contamination OCD, harm OCD, symmetry or order OCD, and hoarding OCD.

Contamination OCD is characterized by an obsessive fear of becoming contaminated, especially with disease or illness.

The biggest variable in OCD treatment is unique to each person, so there is no specific type that is consistently more challenging than others.

However, types like purely obsessional OCD can be difficult to treat since there isn’t a compulsion to navigate.

OCD is a complex disorder, so treatment should be unique and personalized to each individual.

The cause of ROCD is unknown, but trauma may be a factor that contributes to the development of ROCD.
