The Many Faces of OCD

---

Introduction

Obsessive compulsive disorder (OCD) is a mental health condition characterized by persistent, intrusive thoughts, urges, or images that cause significant anxiety or distress ^[1].

Common obsessions include excessive fear of contamination, doubts, need for order or symmetry, aggressive or horrific thoughts, and unwanted disturbing ideas ^[1]. Those with OCD often engage in repetitive behaviors or mental rituals known as compulsions to alleviate their anxiety related to these intrusive thoughts ^[1].

This debilitating disorder can manifest in various forms and severities, from mild to disabling ^[1]. The article explores the different subtypes of OCD, including contamination OCD, harm OCD, symmetry and ordering OCD, and checking compulsions ^[2].

It delves into the specific symptoms, underlying causes, risk factors, and potential complications associated with each subtype, offering a comprehensive guide to this often misunderstood condition ^{[1] [2]}.

Trigger Warning: Please be advised that the following content includes definitions of certain types of OCD may be sensitive or triggering for individuals experiencing OCD (Obsessive-Compulsive Disorder).

Understanding OCD Subtypes

There are 18 different subtypes of OCD, including Checking OCD, Contamination OCD, Harm OCD, Symmetry and Order OCD, and others ^[3].

Each OCD subtype is characterized by specific obsessions and compulsions, but they all involve the same underlying mechanisms of OCD ^[3].

Main OCD Subtypes

1. Contamination OCD: Characterized by obsessions about dirt, germs, or contamination, and compulsions involving excessive washing/cleaning ^[4].
2. Harm OCD: Involves intrusive thoughts about harming oneself or others, and compulsions like checking to prevent harmful accidents ^[4].
3. Symmetry and Ordering OCD: Obsessions with symmetry, order, and arranging objects in a specific way, along with arranging/rearranging compulsions ^[4].
4. Checking OCD: Obsessive concerns about causing harm or making mistakes, leading to compulsive checking behaviors to gain certainty ^{[6] [8]}.
5. Hoarding OCD: Difficulty discarding items due to the perceived need to save them, leading to excessive accumulation of possessions ^[4].

Other OCD Subtypes

Other subtypes include relationship OCD, ‘just right’ OCD, false memory OCD, magical thinking OCD, and obsessions without visible compulsions ^[4]. OCD-related disorders like skin picking, hair pulling, and body dysmorphic disorder are also recognized ^[4].

Treatment Approach

Exposure and Response Prevention (ERP) therapy is considered the most effective treatment for all OCD subtypes ^{[3] [5]}. ERP involves gradually exposing the person to their obsessions while resisting compulsions, helping them learn to tolerate anxiety and uncertainty ^{[5] [6]}.

OCD Subtype	Common Obsessions	Common Compulsions
Checking OCD	Fears of harm, fire, mistakes, inappropriate behavior [6] [8]	Checking appliances, locks, work, children’s safety [6] [8]
Contamination OCD	Dirt, germs, illness [4]	Excessive cleaning, washing [4]
Harm OCD	Harming self/others, violent thoughts [4]	Checking on loved ones, avoiding triggers [4]
Symmetry/Order OCD	Need for order, symmetry [4]	Arranging, rearranging, counting [4]

Treatment typically involves a combination of ERP, cognitive-behavioral therapy, and sometimes medication, depending on the subtype and severity ^{[4] [5] [6] [8] [9]}.

Contamination OCD

Obsessions in Contamination OCD involve an extreme fear of becoming ‘contaminated’ by touching certain substances or items ^[10]. These obsessive fears can revolve around sticky residues, grease, dirt, bodily fluids, feces, urine, and the fear of being coughed or sneezed on ^[10].

Compulsions associated with Contamination OCD include:

1. Repeatedly washing and cleaning oneself (hands, showering, bathing) ^[10]
2. Avoiding public spaces ^[10]
3. Frequently changing or discarding clothes/items that have become ‘contaminated’ ^[10]

Treatment Approaches

Cognitive-Behavioral Therapy (CBT), specifically Exposure with Response Prevention (ERP) and Mindfulness-Based CBT, are effective treatments for Contamination OCD ^[10]. Intensive Outpatient (IOP) treatment programs can also be beneficial for those with severe anxiety related to Contamination OCD ^[10].

Some individuals with Contamination OCD fear spreading contamination to others, rather than just fearing becoming contaminated themselves ^[11]. A common subtype known as ‘Washers’ may wash their hands 50-200 times per day and spend hours showering, often causing skin damage ^[11].

Effective treatment for Contamination OCD involves Exposure and Response Prevention (ERP) therapy, where people gradually face their fears while resisting compulsions ^[11]. Medication like Selective Serotonin Reuptake Inhibitors (SSRIs) can also be helpful in treating Contamination OCD ^[11].

Treatment	Description
Exposure and Response Prevention (ERP)	Gradually facing fears while resisting compulsions [11]
Cognitive Behavioral Therapy (CBT)	Addressing thought patterns and behaviors [10]
Medication (SSRIs, Tricyclics)	Alleviating symptoms through medication [11] [12]
Deep Transcranial Magnetic Stimulation (Deep TMS)	Non-invasive FDA-cleared treatment [12]

Fears in Contamination OCD can stem from realistic concerns like illness or toxic materials, or from magical thinking like beliefs that names, thoughts, or locations can cause contamination ^[12]. Treatments for Contamination OCD include medications like SSRIs and older tricyclic antidepressants, as well as psychotherapy like Exposure and Response Prevention (ERP) and Cognitive Behavioral Therapy (CBT) ^[12].

Harm OCD

Harm OCD is a subtype of obsessive-compulsive disorder (OCD) focused on fears about being harmed or harming oneself or others ^[13]. People with Harm OCD experience intrusive, unwanted thoughts, images, or urges about harm, which they view as an indication of a desire to act, fueling their anxiety ^[13].

Obsessions and Compulsions

1. Obsessions:
   • Images of harming a child ^[13]
   • Urges to self-harm ^[13]
   • Thoughts about driving off a bridge or causing a hit-and-run ^[13]
2. Compulsions:
   • Visible compulsions like removing sharp objects ^[13]
   • Invisible mental compulsions like repeatedly thinking ‘I love my wife’ to counteract an intrusive thought ^[13]
   • Avoiding one’s child out of fear of harming them ^[13]
   • Locking up kitchen knives ^[13]
   • Repeatedly asking for reassurance ^[13]

Harm OCD can manifest through both visible compulsions (like removing sharp objects) and invisible mental compulsions (like repeatedly thinking ‘I love my wife’ to counteract an intrusive thought) ^[13]. Obsessions lead to compulsions, which then make the obsessions even more frequent and intense, creating a vicious cycle ^[13].

Intrusive Thoughts and Ego-Dystonic Nature

Intrusive thoughts in Harm OCD are ego-dystonic, meaning they contradict the person’s values and beliefs, and people with Harm OCD are actually less likely to act on these thoughts than someone who doesn’t have them ^[13]. People with Harm OCD worry that just having the violent thought means they will act on it, even though most people have these types of thoughts occasionally ^[14].

Intrusive Thoughts	Compulsions
Harming loved ones	Hiding dangerous objects
Committing mass murder	Reviewing actions for harm caused
Self-harm	Constantly questioning capability to hurt others
Sexual assault	Seeking reassurance, avoidance, checking behaviors

Treatment Approaches

Exposure and Response Prevention (ERP) therapy is the most effective treatment for Harm OCD, helping the person gradually face their fears and learn to tolerate the anxiety without engaging in compulsions ^{[13] [14] [15]}. Cognitive-behavioral therapy (CBT) with an emphasis on exposure and response prevention (ERP) is also an effective treatment approach ^[15].

Symmetry and Order OCD

Prevalence and Clinical Profile

Symmetry-related obsessions and compulsions are highly prevalent in individuals with obsessive-compulsive disorder (OCD). Approximately 46.6% of OCD patients in a study sample reported primary symmetry-related symptoms ^[16].

Patients with primary symmetry symptoms exhibited significantly higher OCD severity scores, longer illness duration, and greater psychiatric comorbidity, including increased rates of obsessive-compulsive personality disorder (OCPD) and posttraumatic stress disorder (PTSD) ^[16].

Genetic Associations

Interestingly, genetic analysis found a significant association between primary symmetry symptoms and the ANKK1 rs1800497 A2A2 (CC) genotype in Caucasian OCD patients ^[16]. This genotype has been linked to increased dopamine D2 receptor density in the striatum, a brain region involved in reward and movement ^[16]. The authors suggest that primary symmetry symptoms in OCD may represent a distinct clinical and psychobiological profile, potentially reflecting increased striatal dopaminergic activity ^[16].

Characteristics and Symptoms

1. Obsessions:
   • Urge to arrange and order things in a symmetrical way ^[17]
   • Need for balance and a feeling of incompleteness when things are not ‘just right’ ^[17]
2. Compulsions:
   • Arranging and ordering items to meet the need for ‘just right’ or ‘perfection’ ^[17]
   • ‘Evening up’ behaviors, such as adjusting objects to achieve symmetry ^[17]
   • Avoidance of situations that could trigger asymmetry ^[17]

Symmetry OCD can be all-consuming, making it difficult to focus and function in daily life, impacting work, school, relationships, and social activities ^[17].

Treatment Approach

Exposure and Response Prevention (ERP) therapy is considered the first-line treatment for Symmetry OCD, as it helps break the cycle of obsessions and compulsions ^[17]. ERP involves gradually exposing the individual to their obsessions while resisting the urge to engage in compulsions, ultimately leading to a reduction in anxiety and distress.

Comorbidities and Seeking Help

Individuals with Symmetry OCD may also experience other OCD subtypes like Harm OCD, Relationship OCD, etc. ^[18]. Seeking treatment from an OCD specialist as soon as possible is crucial for managing Symmetry OCD and improving overall quality of life ^[18].

Checking OCD

Characteristics and Symptoms

Checking OCD is characterized by persistent and intrusive thoughts, doubts, or fears related to potential harm or mistakes ^{[6] [8]}. These obsessions often revolve around:

1. Fear of causing harm to oneself or others (e.g., leaving the stove on, causing a fire) ^{[6] [8]}
2. Doubts about having completed tasks correctly (e.g., locking doors, turning off appliances) ^{[6] [8]}
3. Concerns about inappropriate behavior (e.g., shouting obscenities in public) ^{[6] [8]}

To alleviate the anxiety caused by these obsessions, individuals with Checking OCD engage in compulsive checking behaviors, such as:

• Repeatedly checking locks, appliances, or work ^{[6] [8]}
• Retracing steps or actions to ensure they were performed correctly ^{[6] [8]}
• Seeking reassurance from others about the completion of tasks or the absence of harm ^{[6] [8]}

Impacts and Comorbidities

Checking OCD can significantly impair daily functioning, as the compulsions can be time-consuming and interfere with work, social activities, and personal relationships ^{[6] [8]}. It is also common for individuals with Checking OCD to experience comorbid conditions, such as:

• Other OCD subtypes (e.g., contamination OCD, harm OCD) ^{[6] [8]}
• Anxiety disorders (e.g., generalized anxiety disorder, social anxiety disorder) ^{[6] [8]}
• Depressive disorders ^{[6] [8]}

Treatment Approaches

Exposure and Response Prevention (ERP)

ERP is considered the gold standard treatment for Checking OCD ^{[6] [8]}. It involves gradually exposing the individual to their obsessions while preventing them from engaging in compulsive checking behaviors. This process helps them learn to tolerate the anxiety associated with their obsessions and break the cycle of compulsions.

Cognitive Behavioral Therapy (CBT)

CBT can be used in conjunction with ERP to address the cognitive distortions and irrational beliefs that fuel the obsessions in Checking OCD ^{[6] [8]}. CBT techniques, such as cognitive restructuring and mindfulness, can help individuals challenge their intrusive thoughts and develop more adaptive coping strategies.

Treatment Approach	Description
Exposure and Response Prevention (ERP)	Gradually exposing the individual to their obsessions while preventing compulsions [6] [8]
Cognitive Behavioral Therapy (CBT)	Addressing cognitive distortions and irrational beliefs [6] [8]

It is important to note that the most effective treatment for Checking OCD often involves a combination of ERP, CBT, and medication (if necessary), tailored to the individual’s specific needs and severity of symptoms ^{[6] [8]}.

Conclusion

In summary, Obsessive Compulsive Disorder (OCD) encompasses a wide range of subtypes, each with its unique set of obsessions and compulsions. From contamination fears and excessive cleaning rituals to intrusive thoughts of harm and relentless checking behaviors, the manifestations of OCD can vary greatly. Understanding these nuances is crucial for proper diagnosis and effective treatment tailored to the individual’s specific needs.

While the journey to recovery can be challenging, seeking professional help from OCD specialists and engaging in evidence-based treatments like Exposure and Response Prevention (ERP) therapy can make a significant difference. By gradually confronting fears and resisting compulsions, individuals with OCD can regain control over their lives and experience improved overall well-being. With the right support and determination, managing OCD becomes an attainable goal.
