Mental Compulsions: The OCD Symptoms Most People Miss

Erica Ricciardi, MA, NCC, LPC

When most people think about Obsessive-Compulsive Disorder (OCD), they imagine visible behaviors: excessive hand washing, checking locks repeatedly, or arranging objects in a specific order. While these can certainly be part of OCD, they only tell part of the story.

Many people with OCD struggle with mental compulsions—internal rituals that happen entirely inside the mind. Because they are invisible to others, and sometimes even difficult for the person experiencing them to identify, mental compulsions are often misunderstood or overlooked. Yet for many individuals with OCD, they are the primary way the disorder operates.

Understanding mental compulsions can be an important step toward recognizing OCD and getting the right treatment.

What Are Mental Compulsions?

Mental compulsions are covert rituals performed in the mind to reduce anxiety caused by intrusive thoughts.

People with OCD experience unwanted thoughts, images, or urges (called obsessions) that feel distressing, disturbing, or completely inconsistent with their values. In response, they perform compulsions in an attempt to neutralize the anxiety or gain certainty that the feared outcome won’t happen.

While some compulsions are behavioral and observable, others happen internally.

Mental compulsions may include:

• Replaying conversations or events repeatedly to analyze what happened

• Silently reassuring yourself that everything is okay

• Mentally reviewing memories to check for evidence

• Repeating phrases, prayers, or mantras in your head

• Trying to “cancel out” a bad thought with a good thought

• Mentally checking whether you really meant a thought or if it says something about who you are

  
  

Because these processes happen internally, they can be easily mistaken for overthinking, rumination, or anxiety, rather than recognized as part of OCD.

Common Types of Mental Compulsions

Mental Reviewing

Mental reviewing involves repeatedly going over a memory or situation to make sure nothing bad happened.

Someone might replay a conversation dozens of times to check if they said something offensive, inappropriate, or harmful. Others may mentally review their day trying to confirm they didn’t accidentally hurt someone or make a mistake.

The problem is that the brain never reaches a satisfying answer, so the reviewing continues.

Seeking Mental Reassurance

Many people with OCD attempt to calm themselves by internally reassuring their fears.

Examples might include:

• “I would never do that.”

• “I’m a good person.”

• “That thought doesn’t mean anything.”

  
  

While reassurance can temporarily reduce anxiety, it actually strengthens the OCD cycle by teaching the brain that the intrusive thought was dangerous enough to require a response.

Mental Checking

Mental checking involves searching the mind for certainty.

Someone might ask themselves questions like:

• Did I mean that thought?

• Did I feel something when I saw that person?

• What if that memory means something about me?

  
  

They may repeatedly scan their thoughts, feelings, or memories trying to confirm that everything is “safe.”

Unfortunately, this internal checking tends to create more doubt instead of resolving it.

Neutralizing Thoughts

Some individuals try to cancel out intrusive thoughts with other thoughts.

For example:

• Thinking a positive thought to replace a disturbing one

• Repeating a phrase until it “feels right”

• Mentally undoing an image with a different image

• 
  

This process is often driven by a belief that thoughts themselves can cause harm—a cognitive distortion known as thought-action fusion.

Why Mental Compulsions Are Hard to Recognize

Mental compulsions are often missed for several reasons.

First, they are invisible. Unlike washing hands or checking locks, there is no outward sign that a ritual is happening.

Second, many mental compulsions resemble everyday thinking patterns like analyzing or problem solving. The difference is that with OCD, the thinking becomes repetitive, urgent, and impossible to resolve.

Finally, people experiencing mental compulsions often feel ashamed of their intrusive thoughts. Because of this, they may keep the struggle entirely private.

The Role of Mental Compulsions in the OCD Cycle

Mental compulsions follow the same cycle as behavioral ones:

1. Intrusive thought appears (“What if I hurt someone?”)

2. Anxiety increases

3. The person performs a mental compulsion (reviewing, reassurance, checking)

4. Anxiety temporarily decreases

5. The brain learns that the thought was dangerous

6. The intrusive thought returns even stronger

   
   

Over time, this cycle can become exhausting and overwhelming.

Ironically, the strategies meant to reduce anxiety are actually what keep OCD alive.

How OCD Treatment Addresses Mental Compulsions

One of the most effective treatments for OCD is Exposure and Response Prevention (ERP).

ERP works by helping individuals gradually face intrusive thoughts and the uncertainty they bring—without performing compulsions, including mental ones.

Instead of trying to analyze, neutralize, or gain certainty about the thought, the goal becomes learning to allow the thought to exist without responding to it.

With practice, the brain learns that intrusive thoughts are uncomfortable but not dangerous, and the urge to perform compulsions begins to weaken.

Final Thoughts

Mental compulsions are one of the most misunderstood aspects of OCD. Because they happen internally, many people live with them for years without realizing that what they’re experiencing is part of a treatable condition.

If you find yourself caught in cycles of mental reviewing, reassurance, or checking, you are not alone—and support is available.

OCD is not about the thoughts you have. It’s about the relationship you’re forced to have with them.

And with the right treatment, that relationship can change.
