Q Why does obsessive-compulsive disorder (OCD) develop?
A Dysregulation of serotonin and hyperactivity of the orbitofrontal-basal ganglia circuit are the primary causes. Genetics, stress, and environmental factors all interact.
Detailed Answer
Neurobiological Causes of OCD
Obsessive-compulsive disorder (OCD) is a psychiatric condition characterized by repetitive intrusive thoughts and compulsive behaviors, driven by serotonin system dysregulation and hyperactivity of the orbitofrontal-striatal-thalamic circuit.
- Serotonin Imbalance — The effectiveness of SSRIs (selective serotonin reuptake inhibitors) supports the central role of serotonin dysregulation.
- Neural Circuit Hyperactivity — The orbitofrontal cortex-caudate nucleus-thalamus loop becomes overactivated, causing danger signals to repeat without resolution.
- Genetic Factors — First-degree relatives have a 2–3 times higher risk of developing OCD compared to the general population.
- Environmental Stress — Severe trauma, chronic stress, and certain infections (PANDAS) can trigger or worsen symptoms.
Korean Medicine Clinic Perspective
In Korean medicine, the Spleen (脾臓) governs contemplation and rumination. Excessive worry and repetitive thinking deplete Spleen Qi (脾氣), and when combined with Liver Qi Stagnation (肝氣鬱結), the mind-spirit (心神) becomes destabilized — manifesting as obsessive symptoms.
