Obsessive compulsive disorder
it is very often not about cleaning
OCD is unwanted intrusive thoughts causing intense distress, and repetitive acts done to relieve that distress. It is widely misunderstood as a preference for tidiness. In reality it is a disabling anxiety condition, the average delay before people seek help is around a decade, and it responds well to a specific therapy.
Please seek help promptly if
- you are having thoughts of harming yourself or ending your life
- compulsions are taking many hours a day or you cannot leave the house
- you are unable to eat, drink or sleep because of rituals
- you have skin damage from washing, or physical harm from compulsions
- someone close to you is seriously worried about you
If you are having thoughts of harming yourself or ending your life, help is available now. Call 999 or go to an emergency department if you have already harmed yourself or feel unable to stay safe. Otherwise call Samaritans free on 116 123 at any hour, text SHOUT to 85258, or call NHS 111 and select the mental health option.
How it works
An obsession is an unwanted, intrusive thought, image or urge that causes intense anxiety. A compulsion is something done to neutralise it — a physical act or a mental one. The compulsion works briefly, which is exactly why the cycle strengthens: each time you perform it, your brain learns that the danger was real and the ritual prevented it.
The themes people do not mention
- Contamination — the well-known one, with washing and cleaning
- Checking — locks, appliances, that you have not harmed someone
- Harm obsessions — intrusive thoughts of hurting someone you love, or of losing control. These are the opposite of intent, and they are distressing precisely because they are abhorrent to you
- Sexual or 'taboo' intrusive thoughts, including thoughts about children, which cause enormous shame and are the least likely to be disclosed
- Religious or blasphemous obsessions (scrupulosity)
- Symmetry and 'just right' feelings
- Relationship or health obsessions
Intrusive thoughts are not intentions
Almost everyone has intrusive thoughts — a fleeting urge to swerve the car, an unwanted violent or sexual image. Most people dismiss them. In OCD they stick, and the distress they cause is misread as evidence that they mean something. They do not. People with harm OCD are not dangerous; people with taboo intrusive thoughts have no desire to act on them. Disclosing these thoughts to a clinician does not result in you being reported or your children removed — it results in the correct treatment. The shame is the main reason people suffer for years.
Mental compulsions count
Not all compulsions are visible. Mental reviewing, counting, praying, mentally checking whether you did something, arguing with the thought, or seeking reassurance are all compulsions, and they maintain OCD just as effectively as handwashing. People with purely mental compulsions are often told they do not have OCD, which is wrong.
Why reassurance backfires
Asking 'are you sure I locked it?' or 'do you think I'm a bad person?' relieves anxiety briefly, so the brain requires more of it next time. Reassurance-seeking is itself a compulsion. This is difficult for families, who naturally want to help — and the most helpful thing they can do is agree in advance, kindly, to stop providing it. Accommodation by family is one of the strongest predictors of poor outcome.
Treatment
- Exposure and response prevention (ERP) is the treatment. It means deliberately facing the trigger and not performing the compulsion, so anxiety rises and then falls on its own. It is uncomfortable, it works, and generic counselling or talking therapy does not.
- SSRIs are effective, generally at higher doses and for longer than in depression — often 12 weeks before full benefit. Many people are undertreated on a depression-level dose.
- Combining ERP and medication works better than either alone for moderate to severe OCD.
- Continue medication for at least a year after improvement to prevent relapse.
- Specialist services exist for severe or treatment-resistant OCD.
