ADHD symptoms are described as persistent difficulties in attention regulation, impulsivity, hyperactivity, emotional control, and executive function. These attention regulation problems may affect academic performance, occupational functioning, relationships, sleep regulation, and daily organization.
This article explains ADHD-related difficulties from both modern neuroscience and Korean Medicine Neuropsychiatry perspectives, focusing on brain circuits, neurotransmitters, autonomic balance, and Korean medicine pathophysiology.
Overview of ADHD Symptoms
Attention-deficit/hyperactivity disorder is a neurodevelopmental condition characterized by persistent patterns of inattention, impulsivity, and hyperactivity that interfere with daily functioning. ADHD symptoms are understood as cognitive and behavioral manifestations involving impaired attention regulation, executive function, emotional control, and behavioral inhibition.
Modern medicine explains ADHD as a disorder involving dysfunction within the prefrontal cortex, basal ganglia, striatum, and fronto-striatal circuits. In Korean medicine, the condition is understood as a disturbance of qi regulation, heart-liver imbalance, qi-blood deficiency, and yin deficiency affecting mental focus and emotional regulation.
Korean Medicine Neuropsychiatry investigates these symptoms through an integrated framework that connects nervous system regulation, autonomic balance, stress response, and Korean medicine concepts. The Korean Society of Oriental Neuropsychiatry studies these interactions as part of an academic approach to Korean medicine-based neuropsychiatric explanation.
Clinical Features of ADHD Symptoms
ADHD symptoms are associated with inattention, distractibility, forgetfulness, poor task persistence, impulsive decision-making, and emotional dysregulation. Inattention may appear as difficulty completing tasks, losing important items, overlooking details, or struggling to follow conversations.
Hyperactivity may be expressed as restlessness, excessive movement, difficulty remaining seated, or a constant sense of internal agitation. In adults, hyperactivity is often described as mental restlessness rather than visible motor activity.
Impulsivity is considered to be a difficulty in behavioral inhibition. It may appear as interrupting others, making rapid decisions, emotional outbursts, impulsive spending, or difficulty delaying gratification.

Neurobiological Causes of ADHD Symptoms
These symptoms may be explained by altered dopamine and norepinephrine neurotransmission. Dopamine is associated with motivation, reward processing, and attention allocation, while norepinephrine is associated with alertness, working memory, and cognitive control.
The prefrontal cortex is involved in executive function, planning, inhibition, and working memory. The basal ganglia, striatum, and fronto-striatal circuits are associated with behavioral regulation, reward sensitivity, and sustained attention.
Attention deficit manifestations are considered to be related to delayed maturation or functional dysregulation of these neural circuits. Stress, sleep disruption, family environment, academic pressure, and emotional burden may intensify symptom severity.
Physiological Changes Related to ADHD Symptoms
Behavioral regulation difficulties are associated with autonomic nervous system imbalance, stress-response dysregulation, and altered arousal regulation. Increased sympathetic activation may contribute to restlessness, irritability, sleep disturbance, and emotional reactivity.
Reduced parasympathetic recovery may make it difficult to calm the body after stress. This physiological pattern may be linked to chronic fatigue, poor sleep quality, sensory sensitivity, and reduced emotional resilience.
Korean Medicine Pathophysiology of ADHD Symptoms
Qi-Blood Deficiency and Attention Regulation
Qi-blood deficiency is understood as insufficient nourishment of the mind and nervous system. This pattern may be associated with poor concentration, forgetfulness, fatigue, and reduced mental endurance.
Yin Deficiency and Restlessness
Yin deficiency is described as a reduced stabilizing and restorative function of the body. It may be linked to sleep disturbance, internal restlessness, emotional sensitivity, and difficulty calming mental activity.
Liver Qi Stagnation and Emotional Dysregulation
Liver qi stagnation is associated with emotional frustration, irritability, impulsivity, and irregular attention regulation. From an integrated perspective, this pattern may correspond to stress-related autonomic instability and emotional dysregulation.
Phlegm Accumulation and Cognitive Clarity
Phlegm accumulation is understood as a functional obstruction that may reduce mental clarity. It may be associated with distractibility, mental fog, cognitive inconsistency, and unstable attention.
Treatment Perspective for ADHD Symptoms
From the perspective of Korean Medicine Neuropsychiatry, treatment is understood as a process of restoring regulatory balance within the nervous system, emotional system, and physiological stress-response network.
ADHD symptoms are approached through nervous system regulation, autonomic balance, sleep stabilization, emotional regulation, and gradual recovery of attentional consistency. This perspective integrates modern neuroscience with Korean medicine concepts such as qi-blood deficiency, yin deficiency, liver qi stagnation, and phlegm accumulation.

Summary of ADHD Symptoms
ADHD symptoms are described as multidimensional manifestations involving executive dysfunction, dopamine and norepinephrine regulation, fronto-striatal circuit changes, autonomic imbalance, and stress-response vulnerability.
In Korean medicine, the condition is understood through qi-blood deficiency, yin deficiency, liver qi stagnation, and phlegm accumulation. These patterns are associated with attention regulation, emotional stability, sleep rhythm, and physiological resilience.
Korean Medicine Neuropsychiatry integrates neuroscience and Korean medicine pathophysiology to explain attention regulation problems, while the Korean Society of Oriental Neuropsychiatry studies these mechanisms through an academic framework involving brain function, autonomic regulation, emotional control, and traditional medical theory.
