Existential OCD (Obsessive-Compulsive Disorder) is a subtype of OCD that revolves around deep, philosophical questions about life, existence, and the universe. People with this condition often experience intrusive, unsettling thoughts about existence that lead to compulsive behaviors, mental rumination, and overwhelming anxiety. Understanding the causes of existential OCD requires exploring psychological, neurological, and environmental factors.
In this article, we’ll dive into what causes existential OCD, focusing on the biological, cognitive, and environmental contributors that can play a role in the development of this condition.
What is Existential OCD?
Before we explore the causes, it’s essential to understand what existential OCD entails. While traditional OCD might involve fears of contamination or order, existential OCD focuses on questions like:
“What is the purpose of life?”
“What happens after death?”
“Do I really exist, or is this reality an illusion?”
These thoughts go beyond normal philosophical reflection. People with existential OCD become stuck in these questions, unable to find peace or certainty, leading to distress and compulsive mental checking or seeking reassurance.
The Role of Brain Chemistry
At the core of OCD, including existential OCD, lies a disruption in brain chemistry. Neurotransmitters, particularly serotonin, play a crucial role in regulating mood and anxiety. In people with OCD, serotonin transmission is often dysregulated, causing the brain to get “stuck” in a loop of intrusive thoughts and compulsive behaviors.
The Serotonin Hypothesis
Studies have shown that individuals with OCD have an imbalance in serotonin levels. Serotonin helps regulate mood and is essential in stopping unwanted thoughts. When serotonin doesn’t function properly, obsessive thoughts—like existential questions—become more persistent, leading to compulsive behaviors meant to reduce the distress caused by these thoughts.
Other Neurological Factors
Overactivity in the Basal Ganglia and Cortico-Striato-Thalamo-Cortical Circuit (CSTC): Brain imaging studies reveal that people with OCD often have increased activity in certain brain regions. The CSTC loop, responsible for regulating thoughts and actions, malfunctions, making it harder for people to “move on” from intrusive thoughts, like those seen in existential OCD.
Dopamine Dysregulation: Another neurotransmitter, dopamine, is often linked to compulsive behaviors in OCD. Some researchers believe dopamine imbalance contributes to the compulsions individuals perform to neutralize their obsessive thoughts.
Cognitive Distortions and Thought Patterns
OCD is often described as a “thought disorder” where intrusive thoughts dominate the mental space. In existential OCD, these thoughts revolve around existential questions that are often unanswerable, leading to feelings of uncertainty. This sense of uncertainty can be particularly hard for people with OCD, as they typically crave control and certainty.
Cognitive Distortions:
Black-and-White Thinking: People with existential OCD may struggle with “all-or-nothing” thinking. For instance, they may feel that if they can’t find a definitive answer to their existential questions, their entire life has no meaning.
Catastrophizing: Those with this condition may jump to worst-case scenarios, such as thinking that not knowing the purpose of life means they will never be happy or at peace.
Intolerance of Uncertainty: Existential OCD thrives on an individual’s inability to tolerate uncertainty. Since philosophical questions often have no clear-cut answers, people with existential OCD become trapped in a cycle of searching for certainty where none exists.
Overestimation of Threat
In OCD, people often overestimate the consequences of their thoughts. In existential OCD, individuals may believe that not finding the “right” answer to a question like “Why am I here?” could lead to profound consequences in their personal life or emotional well-being. This overestimation keeps them stuck in obsessive thinking patterns.

Environmental and Genetic Factors
While brain chemistry and cognitive distortions are central to understanding existential OCD, environmental and genetic factors can also play a significant role in its development.
Family History and Genetics
Research suggests that OCD can run in families. If you have a close family member with OCD, your risk of developing the disorder, including existential OCD, increases. While there is no single “OCD gene,” genetic susceptibility, combined with environmental triggers, can make an individual more prone to developing OCD.
Childhood Experiences
Certain childhood experiences, such as trauma or significant life changes, can act as triggers for existential OCD. People who grew up in highly critical or religious environments, where deep questions about life and existence were constantly posed, may develop a heightened sense of anxiety around these topics later in life.
Stress and Life Transitions
Major life changes—such as graduating, losing a loved one, or experiencing an identity crisis—can trigger existential OCD. These situations make individuals more vulnerable to existential questions, and the obsessive-compulsive cycle takes hold as they seek answers or try to quell their anxiety through rituals or mental checking.
Philosophical and Existential Sensitivity
One unique aspect of existential OCD is the philosophical sensitivity seen in individuals with this condition. People who are naturally inclined to question life’s deeper meanings might be more susceptible to existential OCD. When combined with anxiety and an obsessive-compulsive thinking style, this sensitivity can spiral into a constant need for answers that don’t exist.
Philosophical Perfectionism
Many individuals with existential OCD seek perfect answers to their philosophical questions. They may believe that if they find the “right” answer, their anxiety will disappear. This need for perfectionism drives them deeper into rumination, making it hard for them to accept the ambiguity that often comes with philosophical questions.
Psychological Triggers and External Influences
External stimuli can also trigger existential OCD. These triggers may include:
Reading or hearing about existential themes in philosophy, religion, or science.
Media exposure to movies or books that deal with topics like death, the meaning of life, or the universe.
Conversations with others about existential questions that stir up uncertainty or anxiety.
When triggered, people with existential OCD may seek reassurance from others, return to their obsessive questioning, or perform mental rituals to find peace. Unfortunately, this only reinforces the cycle of obsession and compulsion.
Cultural and Religious Factors
Religion and culture can also contribute to the development of existential OCD. People raised in highly religious households may feel pressured to find meaning or follow specific existential guidelines, leading to intense anxiety when they can’t meet these expectations.
For example, someone raised with strict beliefs about life after death may struggle with doubt, leading to compulsive mental checking about whether they are following the “right” path to guarantee a positive afterlife. In such cases, existential OCD may manifest as a combination of religious and philosophical fears.
Conclusion: A Complex Interaction of Factors
In summary, the causes of existential OCD are a combination of genetic, neurological, cognitive, environmental, and psychological factors. Brain chemistry plays a significant role in the development of OCD, particularly in serotonin and dopamine regulation. Cognitive distortions, such as black-and-white thinking and intolerance of uncertainty, contribute to obsessive thinking about existential questions. Life experiences, genetic predisposition, and philosophical sensitivity can also shape the way existential OCD develops in an individual.
If you or someone you know is struggling with existential OCD, it’s important to seek help from a mental health professional. Cognitive-behavioral therapy (CBT), specifically Exposure and Response Prevention (ERP), has been proven to be highly effective in treating OCD. Understanding the causes of existential OCD is the first step toward breaking the cycle of obsessive thoughts and regaining control over one’s mind.
