OCD
OCD is not about being tidy: what it really is
“I’m a bit OCD” gets said lightly. The actual disorder is something else: an exhausting loop of doubts that will not switch off.
“I’m a bit OCD” is one of those phrases people throw around lightly. It gets used to explain that someone likes their desk aligned, that a crooked picture bothers them, or that they check their work twice before sending it.
The problem is that actual obsessive-compulsive disorder looks almost nothing like that. It is not a charming quirk or a tidy personality trait: it is a mental health condition that eats up hours of the day, causes intense distress, and is often lived in secret for years. And a great many people who have it do not even know that what happens to them has a name and a treatment.
What OCD actually is
Obsessive-compulsive disorder has two pieces that feed each other.
Obsessions are thoughts, images, or urges that show up uninvited, repeat, and cause distress. They are not ideas the person wants to have; on the contrary, they usually clash head-on with their values. That is exactly why they are so frightening.
Compulsions are what the person does to bring that distress down: washing, checking, ordering, counting, repeating a phrase, asking someone to confirm that everything is fine. They can be visible or purely mental —praying silently, going over a memory again and again to make sure nothing happened—.
The loop works like this: the obsession triggers distress, the compulsion relieves it for a while, and that relief teaches the brain that the compulsion “works.” Next time the doubt comes back stronger and asks for more. That is the trap: what soothes in the short term is exactly what sustains the problem in the long run.
Everyone has strange thoughts
This is probably the most liberating finding in all the research on OCD, and almost nobody knows it.
An international team interviewed university students across 15 cities in 13 countries spread over six continents. They asked whether, in the previous three months, they had experienced unwanted intrusive thoughts, images, or urges. Among the nearly 700 participants with no psychiatric diagnosis, over 94% said yes. At two sites the figure was 100%.
And there is an even more revealing detail. Back in 1978, a classic study asked 124 people with no psychiatric treatment whether they had thoughts or urges they found unacceptable: 84% said yes. Those thoughts were then compared with those of patients with clinical obsessions, and experienced judges were asked to guess which came from which group. They struggled to identify the patients’ ones.
That work left a conclusion that still holds: “normal” and clinical obsessions look very much alike in their content; where they differ is in frequency, duration, intensity, and the consequences they bring.
The conclusion matters: having an unpleasant intrusive thought does not mean you have OCD, and it says nothing about the kind of person you are. What makes the difference is not the thought itself, but how much importance is attached to it, how much distress it causes, and what is done to try to control it.
So why isn’t OCD “being tidy”?
Because order is barely one of its faces. When symptoms from thousands of patients are analyzed, several distinct clusters appear: the need for symmetry, contamination fears, hoarding, and taboo thoughts —aggressive, sexual, or religious in content—.
That last group produces the most silent suffering. Someone may have an intrusive image of harming a child they adore, an unbearable doubt about their sexual orientation, or a blasphemous thought right in the middle of mass. None of that means they want to do it, or that they are who they fear they are: in fact, the distress they feel is proof of the opposite. But the shame is so great that many people do not tell anyone —not their family, not their doctor— for years.
And when they finally do tell someone, the problem does not always end there. One study presented written clinical vignettes to 83 mental health providers across Latin America and asked for a diagnosis. More than half failed to recognize OCD when the obsessions were sexual in content (52.7% misdiagnosed); 42% also missed it for harm obsessions, and 34.7% for religious ones. The contamination vignette —textbook OCD— was missed only 11% of the time. Put plainly: the more taboo the content, the likelier it is that even the health system will fail to name it. This is not one country’s problem; internationally, OCD is described as an underdiagnosed and undertreated disorder.
In the international study, these were precisely the least reported intrusions and, at the same time, the hardest ones for people to get out of their heads. If you recognize yourself here: this is a known, well-described, treatable symptom, not a moral defect.
The doubt that will not switch off
If OCD had to be summed up in a single word, that word would be doubt. Not ordinary doubt, the kind resolved by one check. The other kind: the one still there after checking the door five times.
In that same six-continent study, doubting intrusions were the most common of all. And when decision-making has been studied in people with OCD —pooling data from more than 800 patients—, they are found to struggle more in situations where information is incomplete and there is no way to be entirely certain.
This explains something that looks incomprehensible from the outside: it is not that the person cannot remember whether they turned off the gas. It is that remembering is not enough to feel safe. That is why telling someone with OCD to “stop worrying,” or reassuring them over and over that everything is fine, does not help: it feeds the same loop.
It is not a matter of character
OCD affects between 2% and 3% of people over their lifetime, and it does not appear because someone is weak, dramatic, or poorly raised.
Hereditary factors carry substantial weight, though they do not explain everything. And when brain images from more than three thousand people —with and without OCD— are compared, measurable differences show up in a specific brain circuit: the one connecting the cortex with deep structures, which, when it works inefficiently, has been linked to intrusive thoughts and anxiety.
An honest caveat: those differences appear on average, comparing large groups. There is no scan or lab test today that diagnoses OCD; the diagnosis is made by a professional through clinical interview. What those studies do show is that OCD has a real biological basis — it is not a choice or a quirk.
Does OCD get worse over the years?
It is one of the most distressing questions, and the data are reassuring.
A Spanish team followed a group of patients with OCD and a group without the disorder for more than ten years, measuring cognitive performance at the start and at the end. At baseline, patients performed below the others. Ten years later both groups had changed in similar ways: the initial differences stayed stable, with no progressive decline specific to OCD. Over that same period, moreover, the severity of obsessive-compulsive symptoms and of depression had gone down.
Untreated, OCD tends to be chronic and to take up more and more space in a person’s life. But it is not a condition that “destroys” the mind as time passes, and with treatment the outlook improves.
OCD is treatable
This is the part most people do not know: OCD is among the disorders with the best-studied treatments.
There is a specific form of cognitive behavioral therapy, called exposure and response prevention, designed precisely to break the obsession-compulsion loop. And there is medication with solid evidence, always prescribed and adjusted by a doctor. Studies comparing both options show that combining therapy with medication tends to give better results than medication alone, and that the improvement holds at follow-up.
Two honest warnings. First: this therapy is done alongside a trained professional, not on your own with a video from the internet —poorly applied, it can increase distress—. Second: getting treated does not mean intrusive thoughts disappear forever. It means they stop being in charge.
If you are going through a really hard time
OCD can become overwhelming, especially alongside depression. If thoughts of harming yourself appear, do not face them alone: in Peru you can call Línea 113, option 5 (mental health), run by the Ministry of Health, free and available 24 hours. In an emergency, call 106 (SAMU) or go to the emergency room.
When to seek help
The line between a habit and a disorder is not drawn by the content of the thought, but by how much time it takes from you and how much you suffer. An evaluation is worth it if:
- checking, washing, or mental rituals take up more than an hour of your day;
- you are avoiding places, people, or situations so as not to trigger the distress;
- there are thoughts that shame you so much you have never told anyone;
- your work, your studies, or your relationships are suffering;
- someone close to you has become tangled in your rituals — confirming things for you, checking on your behalf—.
One important clarification: if you like order, you are meticulous at work, and none of it causes you distress or eats your time, that is not OCD. That is simply how you are, and it is perfectly fine.
If you recognize yourself in this, a first evaluation is the best starting point. At my practice in Miraflores (Lima) and via video consultation I evaluate obsessive-compulsive disorder with an evidence-based approach. I see patients in Spanish and English and provide a receipt for insurance reimbursement.

Is being very tidy or perfectionist the same as OCD?
No. Order and perfectionism only become part of a disorder when they cause intense distress, consume a lot of time, or interfere with your life. If you like having everything in its place and it does not make you suffer, it is not OCD.
I have horrible thoughts I do not want to have. Does that make me dangerous?
No. Unpleasant intrusive thoughts are extremely common among people with no psychiatric diagnosis at all, and in OCD they are precisely the ones that clash most with the person’s values. The distress you feel points in the opposite direction from what you fear. It is a known, treatable symptom and worth raising in consultation.
Can OCD be cured?
It is usually a chronic condition, but it responds well to treatment: symptoms can be reduced substantially and you can win back the time and freedom OCD was taking. The goal is not to never have an intrusive thought again, but for it to stop governing your day.
Does it help to reassure my family member that everything is fine?
In the moment it relieves, but over time it feeds the loop: the person learns they need that reassurance in order to feel calm. It is one of the points worked on in treatment, with the family included.
