What is OCD?
Obsessive-Compulsive Disorder (OCD) is a mental health disorder that affects approximately 2-3% of the world's population. It is characterized by the presence of obsessions — intrusive, repetitive, and unwanted thoughts, images, or impulses — and compulsions — repetitive behaviors or mental acts that the person feels driven to perform to neutralize the anxiety generated by the obsessions.
OCD is not "being very tidy" or "wanting things clean." It is a disorder that can be deeply disabling, consuming hours of the day in rituals and generating intense emotional suffering.
The OCD cycle
OCD operates as a self-reinforcing cycle:
1. Obsession (intrusive thought)
An unwanted thought arises that generates intense distress. For example: "Did I turn off the gas?" or "I might harm someone."
2. Anxiety
The thought generates an intense wave of anxiety. The person feels they must do something to neutralize the perceived danger.
3. Compulsion (ritual)
The person performs a behavior or mental act to reduce the anxiety: checking the gas 20 times, washing their hands repeatedly, or repeating a phrase mentally.
4. Temporary relief
The compulsion provides brief relief, but it reinforces the cycle. The brain learns that the compulsion is necessary, causing the obsessions to come back even stronger.
The most common types of obsessions
Contamination obsessions
Intense fear of contaminating yourself or contaminating others. Includes fear of germs, chemicals, body fluids, or illnesses. Associated compulsions include washing your hands excessively, avoiding touching "contaminated" objects, or compulsive cleaning.
Checking obsessions
Fear that something terrible will happen because you didn't check well enough. Checking doors, gas, appliances, that you haven't run someone over with the car... Despite checking multiple times, doubt persists.
Symmetry and order obsessions
An intense need for things to be "right" or "perfect." It is not an aesthetic preference, but an internal urgency that, if not satisfied, generates distress that is hard to bear.
Intrusive thoughts of harm
Unwanted thoughts about harming a loved one. These generate the most shame and isolation, since the person fears that these thoughts reflect their real desires (they don't).
Existential obsessions
Repetitive philosophical questions about reality, consciousness, or the meaning of life that turn into inescapable mental loops.
Myths about OCD
- "OCD is being very clean" — False. Contamination OCD is just one subtype, and cleaning is not for pleasure but out of fear
- "Everyone is a bit OCD" — False. Clinical OCD involves significant suffering and functional interference
- "If you have bad thoughts, you're a bad person" — False. Obsessions are ego-dystonic: they go against the person's values
- "OCD is cured with willpower" — False. It is a neurobiological disorder that requires professional treatment
OCD treatment
Exposure and Response Prevention (ERP)
ERP is the treatment of choice for OCD, with efficacy rates of 60-80%. It consists of gradually exposing yourself to situations that generate obsessions without performing the compulsion. In this way, the brain learns that anxiety naturally decreases without the need for the ritual.
Cognitive therapy
Complements ERP by working on dysfunctional beliefs that sustain OCD, such as overestimation of danger, inflated responsibility, or intolerance of uncertainty.
Pharmacological treatment
Selective serotonin reuptake inhibitors (SSRIs) are the first-line medications. They are often combined with psychological therapy for better results, especially in moderate to severe cases.
Practical tips for living with OCD
- Name the OCD: "This isn't me, it's the OCD talking"
- Don't fight the thoughts: trying to suppress them makes them stronger
- Accept uncertainty: life involves uncertainty, and this is tolerable
- Look for a therapist specialized in OCD: not all professionals have specific training in ERP
- Be patient: recovery is not linear, there will be ups and downs
