OCD is often mistaken for tidiness or perfectionism. Clinically it is quite different: unwanted thoughts that cause real distress, and rituals performed to relieve it — a loop that grows untreated, and responds to a specific form of therapy.

What is OCD?
OCD involves unwanted intrusive thoughts (obsessions) and repetitive behaviours or mental rituals (compulsions) performed to ease anxiety. The relief is temporary, which is why the cycle repeats and strengthens. Obsessions are often disturbing and the opposite of your actual values — fears of contamination or harm, or thoughts of a violent, religious or sexual nature. Having them does not mean you want to act on them.
Compulsions are not always visible. Mental rituals — repeating phrases, counting, seeking reassurance — are as much a part of OCD as handwashing, and are often missed because nobody else can see them.
What causes OCD?
OCD arises from genetic vulnerability combined with differences in how brain circuits regulate doubt and threat detection. It is not caused by upbringing, personality weakness or anything you have done — worth stating plainly, as self-blame is common. Contributing factors include:
- A family history of OCD or related conditions
- Differences in brain circuits governing threat detection and doubt
- Onset or worsening during periods of significant stress
- Onset around major life transitions, including pregnancy and childbirth
- Co-occurring anxiety, depression or tic disorders

Common symptoms
Symptoms vary between people, and you do not need to recognise all of these to benefit from an assessment.
- Intrusive, unwanted thoughts or images
- Excessive fear of contamination or harm
- Repeated checking (locks, appliances, etc.)
- Need for symmetry or things “just right”
- Repetitive counting, washing, or arranging
- Rituals that consume significant time (an hour or more daily)
When to seek help
Seek care if intrusive thoughts or repetitive actions consume significant time or disrupt daily functioning.
How OCD is diagnosed
OCD is diagnosed clinically. The assessment establishes what the obsessions are, what compulsions follow, how much time they consume, and how much they interfere with daily life. It also distinguishes OCD from generalised and health anxiety, because the treatment differs. No referral is needed to book.
Many people delay help for years because their obsessions feel shameful to say aloud. Dr Kritika Surana is familiar with the full range OCD produces; describing them will not be met with alarm.

Treatment options
OCD responds well to treatment, but to specific treatment. General counselling and reassurance can make things worse, because reassurance-seeking functions as a compulsion and maintains the cycle.
Exposure and response prevention (ERP). The psychological treatment with the strongest evidence in OCD. It means deliberately approaching what triggers the obsession while not performing the compulsion, so the anxiety falls on its own. Done gradually, at a pace agreed with you, it teaches the brain that the feared outcome does not follow — and that the compulsion was never what prevented it.

Medication. Certain antidepressants are effective in OCD, often at higher doses and for longer than in depression. They typically take eight to twelve weeks to show full benefit, which is explained at the outset so early lack of change is not mistaken for failure.
Family guidance. Families are often drawn into rituals, giving reassurance or accommodating avoidance with the best intentions — which maintains the condition. Where you want them involved, they are shown how to step back supportively.
What recovery looks like
The realistic goal is not that intrusive thoughts disappear — they occur in almost everyone. What changes is the significance attached to them and the compulsion to respond. Progress in ERP is measured in what you can now do rather than how you feel, and can feel harder before it feels easier.
Where medication is used, it is continued well after improvement, because relapse rates on early discontinuation are high. Many people learn to spot the pattern and apply ERP principles themselves if symptoms creep back.

How Trio Mindspace can help
Dr Kritika Surana offers thorough assessments and personalised care plans — often integrating therapy (such as ERP-based approaches) and medication management.

Every plan begins with a full assessment rather than an assumption. Dr Kritika Surana will explain what she thinks is happening, set out the options, and agree the approach with you before anything starts. You can read more about her background and approach, or see all conditions treated at the clinic.
Frequently asked questions
No. This is one of the most distressing misconceptions about OCD. Intrusive thoughts are unwanted and are experienced as alien to your values — that distress is precisely why they cause anxiety. People with OCD are not more likely to act on them.
Exposure and Response Prevention involves gradually and deliberately approaching what triggers the obsession while resisting the compulsion that usually follows. Done at a manageable pace with clinical guidance, it teaches the anxiety to settle on its own. It is one of the best-evidenced treatments for OCD.
OCD is usually described as highly manageable rather than cured outright. With ERP-based therapy and, where appropriate, medication, many people reduce their symptoms to the point where OCD no longer dictates their day.
Preference for order is not distressing. OCD is: the thoughts are unwanted, the rituals feel compulsory rather than chosen, and the time they consume interferes with work, relationships and rest.
No. Intrusive thoughts in OCD are distressing precisely because they conflict with your values — that is what makes them intrusive. People with OCD are not more likely to act on them; the distress and the compulsive checking come from fearing they might. This is one of the most common and most frightening features of the condition, and it is well recognised clinically.
No. Contamination fears are one presentation, but OCD also involves fears of harm, of having made a terrible mistake, of blasphemy, of unwanted sexual or violent thoughts, and a need for symmetry or 'just right' feelings. Many compulsions are mental and completely invisible to others.
Perfectionism is a trait — high standards, sometimes inconvenient, but not usually distressing in itself. OCD involves unwanted intrusive thoughts that cause genuine distress, and compulsions performed to relieve that distress, which consume significant time and interfere with daily life. The distinguishing features are the distress and the loss of control, not the standards.
Reassurance works exactly like any other compulsion: it relieves anxiety briefly, which teaches the brain that the anxiety was dangerous and needed neutralising. The need for reassurance then returns, usually stronger. Treatment involves gradually reducing reassurance-seeking, which is why families are given guidance on how to respond.
