OCD: Patient Information Leaflet
Intrusive, unwanted thoughts (obsessions) that cause intense anxiety, temporarily relieved by repetitive behaviors or mental acts (compulsions).
What is Obsessive-Compulsive Disorder (OCD)?
Obsessive-Compulsive Disorder involves obsessions — recurrent, intrusive, unwanted thoughts, images, or urges that cause significant anxiety — and/or compulsions, repetitive behaviors or mental acts performed to reduce that anxiety or prevent a feared outcome. Common themes include contamination and cleaning, symmetry and ordering, fears of causing harm, and unwanted taboo or aggressive thoughts. Compulsions provide only brief relief, which paradoxically strengthens the cycle, making the obsessions return more strongly over time.
Common symptoms of Obsessive-Compulsive Disorder (OCD)
- Contamination obsessions (fear of germs, dirt, illness) with washing or cleaning compulsions
- Fear of causing harm to oneself or others, with checking compulsions (stoves, locks, re-reading)
- Need for symmetry or exactness, with ordering or arranging compulsions
- Unwanted taboo, violent, or sexual intrusive thoughts, often causing intense shame
- Mental compulsions such as silent counting, praying, or repeating phrases
- Excessive reassurance-seeking from others
- Significant time (often hours daily) spent on obsessions or compulsions
What causes Obsessive-Compulsive Disorder (OCD)?
OCD has a strong genetic component, with heritability estimates around 40–50%. It is understood as a disorder of the brain's error-detection and habit-formation circuitry, causing a persistent 'something is wrong' signal that compulsions temporarily silence. In a subset of children, a sudden onset of OCD symptoms following a streptococcal infection (PANDAS/PANS) points to an autoimmune-mediated mechanism, though this remains a specific and less common presentation.
Treatment options for Obsessive-Compulsive Disorder (OCD)
Exposure and Response Prevention (ERP), a specialized form of CBT, is the gold-standard psychotherapy for OCD and produces durable improvement for most patients. SSRIs are first-line medication but are typically needed at higher doses than used for depression. Combination treatment (ERP plus an SSRI) is generally recommended for moderate-to-severe OCD.
Self-help tips for Obsessive-Compulsive Disorder (OCD)
- Practice resisting compulsions gradually rather than all at once, following an ERP hierarchy
- Avoid seeking repeated reassurance from family or online sources, which reinforces the OCD cycle
- Track obsession/compulsion time to notice gradual improvement
- Maintain regular sleep and stress-management routines, since stress intensifies symptoms
- Involve family in understanding ERP so home life doesn't inadvertently accommodate rituals
What is the outlook (prognosis) for Obsessive-Compulsive Disorder (OCD)?
Without treatment, OCD tends to follow a chronic, waxing-and-waning course. With ERP and/or medication, the majority of people achieve substantial symptom reduction, and many achieve full remission, though a subset with severe or treatment-resistant OCD may need combination treatment or, rarely, more advanced interventions in specialist settings.
When to seek urgent help
Seek urgent psychiatric care if OCD is causing an inability to work, attend school, or leave the house, if compulsions are causing physical injury (e.g., skin damage from excessive washing), or if obsessions are accompanied by thoughts of self-harm or suicide.
