What Is OCD?

OCD is characterised by a cycle of obsessions and compulsions that feels impossible to break. Obsessions are unwanted, distressing thoughts, images, or urges that repeatedly enter your mind. Compulsions are behaviours or mental acts you feel driven to perform in response to obsessions or according to rigid rules.

The key feature of OCD is that these obsessions and compulsions are time-consuming (taking more than one hour per day) or cause significant distress and impairment in your daily functioning. People with OCD usually recognise that their obsessions and compulsions are excessive or unreasonable, but they feel unable to stop them.

OCD is not about being neat, organised, or particular about cleanliness, as it's often portrayed in popular culture. It's a serious mental health condition that can be debilitating without proper treatment. The good news is that OCD is highly treatable with the right approach.

Understanding Obsessions

Obsessions are intrusive thoughts, images, or urges that cause significant anxiety or distress. They're unwanted and feel foreign to your personality - you don't want to have these thoughts, but they keep coming anyway.

Common Types of Obsessions

Contamination Obsessions

• Germs and illness - Fear of getting sick from touching contaminated objects
• Bodily fluids - Disgust or fear of blood, urine, saliva, or other bodily substances
• Chemicals - Fear of exposure to cleaning products, pesticides, or other chemicals
• Environmental contaminants - Worry about asbestos, radiation, or toxic substances

Harm Obsessions

• Harming others - Unwanted thoughts about hurting family members, friends, or strangers
• Harming yourself - Intrusive thoughts about self-injury or suicide
• Accidental harm - Worry that you might accidentally cause harm (like hitting someone with your car)
• Violent images - Disturbing mental pictures of violence or accidents

Sexual Obsessions

• Inappropriate sexual thoughts - Unwanted sexual thoughts about children, family members, or religious figures
• Sexual orientation concerns - Doubting your sexual orientation despite having no genuine uncertainty
• Sexual behaviour worries - Fear of acting inappropriately in sexual situations

• Blasphemous thoughts - Unwanted thoughts about God, religious figures, or sacred things
• Moral concerns - Excessive worry about being a bad person or doing something wrong

• Repetitive - The same thoughts occur over and over
• Time-consuming - They take up significant mental energy and time

Understanding Compulsions

Compulsions are repetitive behaviours or mental acts that you feel driven to perform in response to obsessions or according to rigid rules. They're aimed at reducing anxiety or preventing some dreaded event, but they're either excessive or not realistically connected to what they're meant to prevent.

Common Types of Compulsions

Cleaning and Washing Compulsions

• Hand washing - Washing hands repeatedly, often until they're raw
• Showering rituals - Taking extremely long showers or showering multiple times per day
• Cleaning objects - Repeatedly cleaning items like phones, keys, or doorknobs

• Rigid - Must be done in a very specific way
• Time-consuming - Take up significant time each day
• Anxiety-driven - Performed to reduce anxiety or prevent feared outcomes
• Temporary relief - May provide brief relief, but anxiety returns quickly

The OCD Cycle

OCD follows a predictable cycle that keeps the condition going:

1. Trigger

Something in your environment or a random thought triggers an obsession.

2. Obsession

The unwanted, intrusive thought, image, or urge enters your mind and causes anxiety.

3. Anxiety

The obsession creates intense anxiety, guilt, disgust, or other uncomfortable emotions.

4. Compulsion

You perform a behaviour or mental act to reduce the anxiety or prevent the feared outcome.

5. Temporary Relief

The compulsion provides brief relief from the anxiety.

6. Reinforcement

Because the compulsion reduced anxiety, your brain learns that compulsions "work," making you more likely to do them again.

7. Return of Obsession

The relief is temporary, and the obsession returns, often stronger than before.

This cycle continues and often gets worse over time without treatment. The compulsions that initially provided relief become less effective, leading to more elaborate or frequent rituals.

Causes and Risk Factors

Biological Factors

• Genetics - Having family members with OCD increases your risk
• Brain structure - Differences in brain circuits involving the orbitofrontal cortex, anterior cingulate cortex, and striatum
• Neurotransmitters - Imbalances in serotonin and other brain chemicals
• Brain function - Overactivity in certain brain regions involved in error detection and habit formation

Psychological Factors

• Thought patterns - Tendency to overestimate threat and responsibility
• Intolerance of uncertainty - Difficulty tolerating doubt or ambiguity
• Perfectionism - Setting unrealistically high standards
• Thought-action fusion - Believing that having a thought is as bad as acting on it
• Inflated responsibility - Feeling overly responsible for preventing harm

Environmental Factors

• Stressful life events - Trauma, major life changes, or ongoing stress
• Childhood experiences - Strict parenting, trauma, or early responsibility for others' safety
• Infections - Some cases may be triggered by streptococcal infections (PANDAS)
• Substance use - Certain drugs may trigger or worsen OCD symptoms

Risk Factors

• Age - Often begins in childhood, adolescence, or early adulthood
• Gender - Affects men and women equally, but may begin earlier in males
• Family history - Having relatives with OCD or other mental health conditions
• Other mental health conditions - Having anxiety, depression, or tic disorders

• Taboo thoughts - Often involves sexual, violent, or religious obsessions
• Misunderstood - Often misdiagnosed because compulsions aren't visible

Treatment

OCD is highly treatable, and most people can achieve significant improvement with proper treatment.

Cognitive Behavioural Therapy (CBT)

Exposure and Response Prevention (ERP)

• Gold standard treatment - Most effective therapy for OCD
• Gradual exposure - Slowly facing feared situations or thoughts
• Response prevention - Resisting the urge to perform compulsions
• Hierarchy - Starting with easier exposures and working up to harder ones
• Habituation - Learning that anxiety decreases naturally without compulsions

Cognitive Therapy

• Identifying thinking errors - Recognising unhelpful thought patterns
• Challenging beliefs - Questioning the accuracy of OCD thoughts
• Developing balanced thinking - Creating more realistic and helpful thoughts
• Reducing responsibility - Learning that you're not responsible for preventing all harm

Medications

Selective Serotonin Reuptake Inhibitors (SSRIs)

• Fluoxetine (Prozac) - FDA-approved for OCD
• Sertraline (Zoloft) - FDA-approved for OCD
• Paroxetine (Paxil) - FDA-approved for OCD
• Fluvoxamine (Luvox) - Specifically approved for OCD
• Higher doses - OCD often requires higher doses than depression

Tricyclic Antidepressants

• Clomipramine (Anafranil) - First medication proven effective for OCD
• Side effects - More side effects than SSRIs but very effective for some people

Atypical Antipsychotics

• Augmentation - Sometimes added to SSRIs for treatment-resistant OCD
• Aripiprazole (Abilify) - Most commonly used for OCD augmentation
• Risperidone (Risperdal) - Sometimes used for severe OCD

Combination Treatment

• ERP plus medication - Often more effective than either treatment alone
• Comprehensive approach - Addresses both behavioural and biological aspects
• Individual needs - Treatment plan tailored to your specific symptoms

Other Treatments

• Acceptance and Commitment Therapy (ACT) - Learning to accept unwanted thoughts
• Mindfulness-based treatments - Developing awareness and acceptance of thoughts
• Family therapy - Helping family members support recovery
• Support groups - Connecting with others who have OCD

Living with OCD

Daily Management

• Practice ERP - Continue exposure exercises even after therapy ends
• Resist compulsions - Use strategies learned in therapy to resist rituals
• Manage stress - Stress can worsen OCD symptoms
• Maintain routines - Structure can help, but avoid rigid rituals
• Stay connected - Maintain relationships and social activities

Family and Relationships

• Educate loved ones - Help family and friends understand OCD
• Avoid accommodation - Family shouldn't participate in or enable compulsions
• Set boundaries - Limit reassurance-seeking and checking behaviours
• Support recovery - Encourage treatment and celebrate progress

Work and School

• Accommodations - May qualify for workplace or academic accommodations
• Manage perfectionism - Learn to accept "good enough" rather than perfect
• Time management - Plan extra time for tasks that trigger OCD
• Seek support - Use employee assistance programs or student counselling services

Setbacks and Relapse

• Normal part of recovery - Setbacks don't mean treatment has failed
• Identify triggers - Recognise what situations worsen your symptoms
• Return to basics - Go back to ERP exercises and coping strategies
• Seek help - Contact your therapist if symptoms worsen significantly
