One psychological disorder that can result from the inability of an internal mechanism to perform its function is obsessive-compulsive disorder (OCD). OCD is characterized by the presence of intrusive and persistent thoughts, images, or impulses (known as obsessions) that cause significant distress and anxiety, and the use of repetitive behaviors or mental acts (known as compulsions) to neutralize or reduce the anxiety caused by the obsessions.

In OCD, the internal mechanism that is not functioning properly is a person’s ability to suppress intrusive, unwanted, or distressing thoughts or to resist engaging in compulsive behaviors or mental acts. Normally, our brains have a system of checks and balances that allow us to filter out irrelevant or unpleasant thoughts and to control our impulses and behaviors based on what is appropriate or necessary in a particular situation. However, in people with OCD, this system may be disrupted or malfunctioning, causing them to experience persistent and distressing obsessions that they cannot control or eliminate, and to perform compulsive behaviors or mental acts that are difficult to resist or give up.

For example, a person with OCD may have obsessions about contamination or germs, leading them to frequently wash their hands or clean their surroundings to reduce their anxiety. However, this compulsive behavior only provides temporary relief, and the anxiety and distress caused by the obsessions tend to return or worsen over time. Similarly, someone with intrusive thoughts about harming themselves or others may engage in mental rituals or checking behaviors to reduce the anxiety caused by these thoughts, but this may only reinforce their fears and increase their sense of responsibility for preventing harm.

Treatment for OCD typically involves a combination of medication, such as selective serotonin reuptake inhibitors (SSRIs), and cognitive-behavioral therapy (CBT), which focuses on changing negative thought patterns and breaking the cycle of obsessions and compulsions.
