Modern medicine defines obsessive-compulsive disorder as a mental disorder related to brain dysfunction. In particular, hyperactivation of the brain's corticostriatal-thalamocortical loop is identified as a core cause. This loop is involved in shaping thoughts, actions, and habits. In individuals with obsessive-compulsive disorder, specific thoughts repeat abnormally, or compulsive behaviors meant to relieve anxiety solidify into fixed patterns. An imbalance of neurotransmitters such as serotonin, dopamine, and GABA also plays an important role. Serotonin, in particular, is deeply involved in regulating anxiety and impulses as well as mood, sleep, and appetite. Because dysfunction in the serotonergic system is frequently observed in individuals with obsessive-compulsive disorder, selective serotonin reuptake inhibitor medications are primarily used.
How, then, can Donguibogam's concepts of stabilizing the heart and Shenmen (HT7) be understood in modern medical terms? Multiple studies suggest that acupuncture treatment, particularly stimulation of Shenmen (HT7), may positively influence changes in brain function. Stimulating Shenmen (HT7) can help support autonomic nervous system balance by increasing parasympathetic nervous system activity. The autonomic nervous system connects directly to the stress response and plays an important role in regulating feelings of anxiety. When the parasympathetic nervous system is activated, heart rate decreases, blood pressure stabilizes, and the body shifts into a rest-and-digest state, reducing anxiety.
Furthermore, research indicates that stimulating Shenmen (HT7) may suppress hyperactivation of the amygdala, which processes anxiety and fear, and enhance the function of the prefrontal cortex, which plays a central role in emotional regulation. In terms of neurotransmitters, acupuncture treatment is thought to contribute to mood improvement and anxiety relief by modulating the secretion of various neurotransmitters such as serotonin, norepinephrine, and endorphins. Even beyond obsessive-compulsive disorder, studies involving individuals with anxiety disorder or depression have reported cases where acupuncture treatment induced structural and functional changes in the brain with positive outcomes. In this way, this single small point called Shenmen (HT7) influences the vast network of the body and mind, offering scientific grounding for gradually easing the hold of obsessive thoughts and compulsive behaviors.
