Constantly Checking and Repeating: Could It Be Obsessive-Compulsive Disorder? A Korean Medicine Approach

Modern medicine examines the Donguibogam concept of the spirit in greater detail through neuroscience and psychology. Obsessive-compulsive disorder is not merely a problem of having a sensitive personality; it is understood as an illness caused by a complex interplay of regional brain dysfunction and neurotransmitter imbalances. It is akin to a car's brake system failing, causing the vehicle to speed ahead without being able to stop where intended. The core brain regions involved are the basal ganglia and the connected frontal cortex areas. Within the frontal cortex, the orbitofrontal cortex and the anterior cingulate cortex play crucial roles in deciding whether to initiate or halt actions, detecting errors or dangers, and regulating anxiety. In individuals with obsessive-compulsive disorder, these areas are known to show hyperactivation or abnormal connectivity. For instance, the orbitofrontal cortex determines that a stimulus is important and prompts a response; in obsessive-compulsive disorder, this evaluation becomes excessive, triggering obsessive thoughts that even minor stimuli are dangerous or must be repeated. Furthermore, imbalances in the neurotransmitter serotonin are deeply connected to obsessive-compulsive disorder. Serotonin is an essential substance involved in regulating mood, sleep, appetite, and anxiety, and many individuals with obsessive-compulsive disorder exhibit dysfunction in the cerebral serotonergic system. This is precisely why medications currently used for obsessive-compulsive disorder primarily work by inhibiting serotonin reabsorption to elevate serotonin concentrations in the brain. Additionally, hyperactivation of the amygdala, often called the brain's fear circuit, is closely tied to the anxiety of obsessive-compulsive disorder. The amygdala detects threats and generates fear responses. Individuals with obsessive-compulsive disorder frequently experience excessive anxiety or fear even toward ordinary stimuli, repeatedly engaging in compulsive behavior to relieve this distress. For instance, handwashing becomes a repetitive act to escape the obsessive thought of contamination. While this behavior temporarily alleviates anxiety, it ends up reinforcing the obsessive loop over the long term. In conclusion, modern medicine views obsessive-compulsive disorder as a brain disorder arising from a combination of genetic factors, neurobiological factors, and environmental stressors. Based on this understanding, patients receive relief through various approaches, including pharmacotherapy with selective serotonin reuptake inhibitor antidepressants and cognitive behavioral therapy, particularly exposure and response prevention therapy. Obsessive-compulsive disorder is an illness difficult to overcome through willpower alone, so if you find yourself wondering while reading this, do not hesitate to seek professional help. I support you in regaining firm control of your brain's brakes.
