What Causes OCD?

Obsessive-compulsive disorder (OCD) is a complex mental health disorder that causes persistent, unwanted thoughts (obsessions) and repetitive behaviors (compulsions). But what leads to this distressing disorder? This blog aims to delve into the causes of OCD, providing a clearer understanding of its origins and risk factors.

OCD: A Brief Overview

Individuals with OCD often find themselves trapped in a cycle of obsessions and compulsions. Obsessions are intrusive and unwanted thoughts, images, sensations, or urges that cause severe physical and psychological distress or anxiety. Some common obsessions include fear of germs or contamination, unwanted or taboo thoughts, and wanting to do or arrange things in the “perfect order.”

Compulsions are behaviors or mental acts that a person may feel driven to perform, often in response to an obsession. These can include excessive cleaning or handwashing, arranging things in a specific order, repeatedly checking on things, such as whether the doors and windows are locked or if the oven is off, or compulsive counting/repeating certain words over and over.

It’s important to note that everyone has unwanted or intrusive thoughts at times, and many people double-check things like their stove or door and windows just to be sure everything is in order. However, if these thoughts and behaviors occur frequently and interfere with your daily life, responsibilities, and relationships, it may be a sign that you have OCD.

Causes Of OCD


A significant body of research suggests that genetics play a crucial role in the development of OCD. Studies have found that individuals with a first-degree relative (such as a parent or sibling) who has OCD are at a higher risk of developing the disorder.

Twin studies have revealed that genetic predisposition increases the risk of developing OCD by 47 to 58 percent. However, not everyone with a family history of OCD will develop the condition, and not everyone with OCD has a family history of the condition, indicating that other factors are also at play.

Brain Structure & Function

Differences in brain structure and function have also been linked to OCD. Certain areas of the brain, including the frontal cortex and subcortical structures, appear to function differently in people with OCD.

These differences may affect the way an individual processes information, potentially leading to obsessive thoughts and compulsive behaviors. Another factor that has been implicated as a potential cause for OCD development is altered brain chemistry, with serotonin and dopamine being the main culprits.

Environmental Factors & Life Events

Life events and environmental factors can also contribute to the development of OCD. Traumatic or stressful events, such as physical or sexual abuse, neglect, or other forms of trauma, may trigger the onset of OCD, particularly in individuals who are genetically predisposed to the disorder. Additionally, certain societal or familial beliefs or behaviors can exacerbate OCD symptoms.

Co-Occurring Mental Health Conditions

OCD frequently co-occurs with other mental health disorders, such as depression, anxiety disorders, and tic disorders. These conditions may not cause OCD, but they are associated with changes in brain chemistry and/or structure which could hinder normal functioning and increase susceptibility to OCD.

Ketamine Infusions & OCD

Emerging research has shown that ketamine, a powerful anesthetic and pain reliever, can also provide rapid and robust relief for individuals battling with OCD. Traditionally used in anesthesia, ketamine is now being explored as a novel treatment for various mental health disorders, including depression, anxiety, PTSD, and notably, OCD.

Ketamine works differently from conventional OCD medications. While traditional drugs often target the serotonin or dopamine pathways, ketamine acts on the glutamate system – a different chemical messenger in the brain.

By blocking a particular receptor in the glutamate pathway known as the N-methyl-D-aspartate (NMDA) receptor, ketamine promotes the formation of new neural connections, enhancing the brain’s flexibility and capacity to control mood and thought patterns.

This new approach may provide relief for individuals who have not responded well to traditional OCD treatments, which primarily focus on serotonin reuptake inhibitors (SSRIs) and cognitive-behavioral therapy (CBT).

Several clinical studies have shown that ketamine can quickly reduce the severity of OCD symptoms, often within hours of administration. Furthermore, its effects can last for a week or longer, providing significant respite from the persistent cycle of obsessions and compulsions.

It’s important to note, however, that while ketamine treatment can offer substantial relief, it is not a cure for OCD and should be part of a comprehensive treatment plan including therapies like CBT.
