Definition

Post-Concussion Syndrome (PCS) is a complex syndrome where symptoms such as headache, dizziness, brain fog, decreased memory and concentration, sleep disorders, emotional instability, and sensitivity to light and noise persist for more than 2 weeks to 3 months following a mild Traumatic Brain Injury (mTBI). It is characterized by a gap where "tests are normal, yet symptoms are debilitating," as structural abnormalities are often not visible on CT or MRI.

Korean Medicine views this as a state where Qi around the brain is scattered and the circulation of Blood is blocked due to external impact—specifically, "abnormality of Brain Qi and disruption of Brain Blood." In the early stages, Blood Stasis (瘀血) and Qi Counterflow (氣逆) occur; over time, Deficiency of Qi and Blood (氣血虛弱) and Liver-Kidney Yin Deficiency (肝腎陰虛) accumulate, leading to chronicity. Therefore, PCS is not merely a "temporary shock" to the brain, but a state of delayed functional recovery in the brain-neck-vestibular-visual-autonomic nervous system network. Korean Medicine pattern identification (Bianzheng) serves as a language to distinguish the different stages and subtypes of this delayed recovery.

Core Integrative Proposition: Post-concussion syndrome involves a delay in functional recovery that is not visible on imaging. While modern medicine explains this through abnormalities in brain metabolism, axons, and the autonomic nervous system, Korean Medicine explains it through pattern identification stages such as Blood Stasis, Deficiency of Qi and Blood, Phlegm-Dampness, and instability of the Heart and Mind. Only by combining these two lenses can fundamental recovery from subjective symptoms be achieved and chronicity prevented.

What Patients Actually Experience

What Patients Actually Experience

People suffering from post-concussion syndrome often say, “The tests are normal, so why am I like this?” If no cerebral hemorrhage or fracture is seen on a CT or MRI after an accident, it is easy to receive reactions from those around them like, “It wasn’t even a major injury.” However, the head feels foggy, headaches are constant, and thoughts do not return to how they used to be. This gap is the core suffering of post-concussion syndrome.

Kim Min-jun (24, university student) still has a headache three weeks after a car accident. It feels as if there is a fog inside his head, and lecture content does not enter his mind. Friends ask, “Are you feeling better now?” but he is in the same state every day. When he tries to exercise, the headache worsens, making it difficult to attend classes the next day. He doesn’t know why his head keeps feeling foggy when the CT is normal.

Lee Ji-hye (42, freelance designer) experiences recurring migraines even two months after the accident. Symptoms return when her workload increases or when her physical strength drops while caring for her child. Her short-term memory has declined, causing her to forget meeting appointments or not remember where she saved files. Just when she thinks she might be okay, she feels pain again if she overexerts herself. Distrust regarding a full recovery builds up.

Park Seo-jun (35, IT developer) struggles with office lighting and monitor light. Even after just 30 minutes under fluorescent lights, it feels like his head is splitting, and small keyboard sounds or colleagues' conversations are extremely bothersome. Since overtime and screen exposure are essential for his job, going to work itself is painful. He is becoming increasingly isolated socially and is exhausted from explaining his condition.

Choi Ok-sun (68, housewife) feels the greatest fear after a fall. She is afraid to go outside for fear of falling again. Her heart pounds, and her neck is stiff and difficult to turn. Her fingertips are numb, and it is difficult to do housework as she used to. Hearing that recovery is slow due to her advanced age, she worries about becoming a burden to her family.

What they all commonly complain of is “invisible pain.” It is not caught by imaging tests, but it is a state where the functional recovery of the brain is incomplete. In Korean medicine, this is viewed as a state where the circulation of Qi and Blood around the brain is blocked (Blood Stasis, 瘀血), energy is disrupted due to the impact (Qi Reversal, 氣逆), and the spirit cannot find stability (Heart and Gallbladder Deficiency, 心膽虛弱). Although symptoms vary for each individual, they share the commonality that the recovery momentum of the brain and body has decreased following the trauma.

The point patients find most frustrating is hearing only that “it will get better with time.” Time helps, but for some people, symptoms become chronic or recur. In particular, if there is no appropriate recovery intervention in the early stages, headaches, dizziness, brain fog, sleep disorders, and emotional instability form a cycle and deepen. It is important to recognize that these are not simply “symptoms to be endured,” but a state requiring recovery of brain energy metabolism, blood flow, and neural networks.

What I want to emphasize in this section is that post-concussion syndrome is not a “psychological problem” or “malingering.” Even subjective symptoms are linked to minute functional changes in the brain. Modern medicine explains this through ionic and metabolic disturbances, mitochondrial dysfunction, axonal and synaptic damage, and autonomic nervous system abnormalities. Korean medicine views the same phenomenon as a communication disorder of Qi, Blood, Nutritive (Ying), and Defensive (Wei) systems, and categorizes patterns based on individual symptoms. These two perspectives are merely different languages looking at the same person and are not mutually exclusive.

What patients actually experience is the process of those symptoms taking away their daily lives, rather than the symptoms themselves. Studying, working, childcare, social life, and even going out. There is a strong desire to return to their former selves. In that process, the lack of understanding from those around them and the uncertainty of treatment become the biggest barriers. An integrative medical approach starts from this point. Even if tests are normal, the patient’s body is demanding recovery, and the purpose of treatment is to assist that recovery.

The Lens of Modern Medicine

Concussion is a representative form of mild traumatic brain injury (mTBI) where structural rupture is not apparent. When an external impact is applied to the head, the brain is shaken microscopically within acceleration-deceleration and rotational forces. In this process, ion channels in the neuronal membrane temporarily collapse, disrupting the flow of K⁺, Na⁺, and Ca²⁺, and causing a surge in ATP demand. Simultaneously, mitochondrial function declines, oxidative stress and cytokines (TNF-α, IL-6) rise, and microscopic damage accumulates in axons and synapses. Even if not visible on imaging, the brain's energy and information circuits have entered a state of temporary shock.

A condition where these changes persist for more than 2 weeks to 3 months, manifesting as a complex of symptoms such as headache, dizziness, brain fog, decreased memory and concentration, sleep disorders, emotional instability, and sensitivity to light and noise, is called Post-Concussion Syndrome (PCS). Diagnosis is made clinically. A GCS score of 13–15, brief loss of consciousness, or pre- and post-traumatic amnesia serve as clues; CT and MRI are primarily used to exclude structural lesions such as hemorrhage or fractures. Although abnormalities in white matter microstructure or functional networks may be seen in advanced imaging (DTI, fMRI), most cases receive a "normal" finding in routine clinical practice. Assessment tools used include RPQ, SCAT5, ImPACT, KHIT-6, HIT-6, MoCA-K, and sleep scales.

Standard treatment is symptom-oriented. In the acute phase, physical and cognitive rest and a gradual return-to-activity protocol are recommended. For headaches, NSAIDs or triptans are used; for dizziness, vestibular rehabilitation therapy (VRT); for visual symptoms, oculomotor and visual processing training; for cognitive impairment, cognitive rehabilitation; and for emotional and sleep issues, CBT, sleep hygiene, SSRIs/SNRIs, and melatonin are employed. Multidisciplinary rehabilitation (neurology, rehabilitation medicine, clinical psychology, physical therapy, occupational therapy) is ideal, but coordination is often difficult in reality.

However, the limitations of modern medicine are also clear. There is no yet agreed-upon treatment protocol for chronic PCS. Most pharmacological and non-pharmacological therapies are limited to symptom relief and fail to reverse the pathophysiological cascade. Due to a lack of objective biomarkers or imaging markers, diagnosis and assessment of treatment response are difficult, and patients often express frustration with a one-size-fits-all approach due to high individual heterogeneity. In particular, being told that tests are normal can sound to the patient as if "my symptoms are not being recognized." This gap is precisely where integrative medicine and Korean medicine can contribute.

The Lens of Traditional Korean Medicine

Traditional Korean Medicine (TKM) views post-concussion sequelae as "a state where the brain (腦) is damaged due to the vibration of the head." The core pathology is that the Qi (氣) around the brain is scattered and Blood (血) becomes stagnant due to trauma, preventing the smooth supply of Qi, Blood, and nutrients to the brain. Areas that modern medicine refers to as "functional decline" are interpreted in TKM through pattern identification (辨證) such as Blood Stasis (瘀血), Qi and Blood Deficiency (氣血虛弱), Liver and Kidney Yin Deficiency (肝腎陰虛), Phlegm-Dampness (痰濕), and Mental Instability (心神不安). Subjective symptoms that remain even when clinical tests are normal are seen as signals that these residual patterns have not yet been resolved.

The TKM pathogenesis of post-concussion sequelae is not simple. When external impact blocks the communication of microvessels around the brain, Blood Stasis is created, which in turn decreases the circulation of Qi and Blood. When the supply of nutrients to the brain and surrounding muscles and nerves is cut off, pain and functional decline appear. Over time, a complex progression occurs where Heat (熱) may cluster with Blood Stasis, Qi and Blood may become deficient due to long-term exhaustion, Phlegm-Dampness may envelop the head, or the mind and spirit may become unstable. Because of this, the pattern identification for the initial and chronic phases differs, and the treatment principles change accordingly.

Pattern identification is subdivided according to an individual's symptom patterns, constitution, and stage. The table below summarizes the common pattern types encountered in post-concussion sequelae, their clinical characteristics, treatment principles, and modern research contexts.

The Blood Stasis Obstruction type is the most common underlying pattern from immediately after trauma through the chronic phase. When blood circulation around the brain is blocked due to trauma, pain and brain fog occur. If Heat is accompanied, it progresses to Blood-Heat Obstructing Collaterals, which can increase head discomfort, insomnia, and nausea. In such cases, prescriptions that combine cooling the blood (凉血), activating blood (活血), and unblocking collaterals (通絡) are considered. In “Clinical Research Trends on Traditional Chinese Medicine Treatment for Post-Concussion Syndrome - Focusing on CNKI Search” (J Int Korean Med, 2021), an analysis of 22 clinical studies confirmed that prescriptions related to Blood Stasis and Blood-Heat were widely used to improve headache, dizziness, nausea, and memory in PCS.

The Qi and Blood Deficiency type often develops due to long-term fatigue and stress during the post-accident recovery process. Patients complain, "I feel tired even though I haven't done anything." This is a state where Qi and Blood are exhausted and fail to supply energy to the brain; the approach focuses on tonifying Qi (補氣), nourishing Blood (養血), and strengthening the Spleen (健脾). Herbal Medicine for Traumatic Brain Injury: A Systematic Review and Meta-Analysis of RCTs and Limitations (Frontiers in Neurology, 2020) reported that herbal medicine is effective as an adjunctive therapy for improving functional outcomes and clinical symptoms after TBI with few side effects. However, it also pointed out that the level of evidence is limited due to study quality and prescription heterogeneity.

The Liver and Kidney Yin Deficiency type is often accompanied by dizziness, tinnitus, insomnia, and heat in the palms and soles. It occurs when the brain marrow (腦髓) and essence-yin (精陰) are damaged after trauma, failing to properly nourish the head. Formulas such as Cheonmagudeung-tang (Tianma Gouteng Yin), Yukmijihwang-hwan (Liuwei Dihuang Wan), and Jihwang-eumja (Dihuang Yinzi) are used with modifications based on the pattern. The Phlegm-Dampness Clouding the Top type is close to brain fog, characterized by a heavy, cloudy head and nausea. Formulas like Banhabakchulcheonma-tang (Banxia Baizhu Tianma Tang) and Ondam-tang (Wendan Tang) are used to dry Phlegm-Dampness and raise Clear Yang.

The Mental Instability type is a state where the Heart and Gallbladder (心膽) are weakened by the psychological shock of the trauma. Anxiety, insomnia, memory impairment, and emotional instability are prominent, and formulas such as Gammaekdaejo-tang (Ganmai Dazao Tang), Cheonwangbosim-dan (Tianwang Buxin Dan), and Sansoin-tang (Suanzaoren Tang) are utilized according to the pattern. This pattern is deeply connected to modern medicine's PTSD, anxiety, depression, and sleep disorders; TKM views this not as a simple psychiatric issue but as an imbalance of Qi, Blood, Nutritive (Ying), and Defensive (Wei) systems after trauma.

TKM treatment addresses these patterns individually or in combination. In actual clinical practice, Blood Stasis and Qi deficiency often coexist, or Mental Instability may overlap with Phlegm-Dampness. Therefore, even for the same diagnosis, the prescription and treatment process vary for each patient. This is the core of pattern-based personalized treatment.

Modern research is also gradually confirming the potential of TKM interventions. In Acupuncture Improves MRI Brain Microstructure with Postconcussion Symptoms in Mild TBI: A Randomized Controlled Trial (PubMed, 2025), after 14 sessions of acupuncture over 4 weeks, the PCS score in the verum group decreased by -5.2 ± 6.9 (P=.002), and improvements in white matter microstructure on MRI correlated with symptom improvement. The sham group only decreased by -1.2, and the waiting list by -0.3. This suggests that acupuncture may be linked to the recovery of brain microstructure beyond symptom relief. A meta-analysis in Acupuncture combined with hyperbaric oxygenation for TBI (Frontiers in Neurology, 2025) reported that the combination of acupuncture and hyperbaric oxygen therapy was more advantageous for functional recovery than hyperbaric oxygen therapy alone.

There is also research on herbal ingredients. In Effect of a Boswellia and Ginger Mixture on Memory Dysfunction of mTBI Patients (BMC/PMC, 2022), a mixture of Boswellia and Ginger was effective in improving memory impairment after mild TBI. In a double-blind RCT, Boswellia serrata extract cognitive benefits in TBI (Brain Injury, 2022) showed that K-Vie™ (Boswellia) resulted in significant improvements in cognitive assessments such as RAVLT, DSST, and TMT-B. In Korea, improvements in MMSE-K, MoCA-K, and Mini-Memory Test were reported in cases of headache and memory impairment after TBI treated with modified Seogakjihwang-tang for 60 days.

The mechanisms of action in TKM intersect with modern pathophysiology at several points. These include antioxidant and anti-inflammatory effects, mitochondrial protection, regulation of BDNF-Akt/GSK-3β signaling, and improvement of cerebral blood flow and autonomic balance. This demonstrates that TKM does not simply suppress symptoms but can act to regulate the secondary injury cascade remaining after trauma and help the brain restore its self-healing capacity.

However, TKM treatment is not a panacea. Acute cerebral hemorrhage, fractures, and decreased consciousness must be evaluated by modern medicine first. TKM provides value in recovering functional decline and residual symptoms after structural abnormalities have been ruled out. An integrative medical approach involves using both lenses together according to the stage and symptoms, rather than thinking of Western and Korean medicine separately.

Integration — Where Two Lenses Meet

Modern medicine views concussion sequelae as a "state where no structural abnormalities exist, but function fails to recover." Korean medicine views the same state as a "condition where Qi (氣) is scattered and Blood (血) is obstructed, preventing smooth nutritional supply to the brain." The two lenses illuminate different layers of the same person. Modern medicine addresses damage and recovery at the cellular, molecular, and circuit levels, while Korean medicine addresses how that damage manifests in the individual's overall Qi and Blood, Ying-Wei (nutritive and defensive Qi), and Zang-Fu (organ) functions.

The table below connects the primary mechanisms identified by modern medicine with the pattern identification (辨證) of Korean medicine at a granular level. This mapping is not a simple comparison but serves as a tool for clinical reasoning, indicating that "this patient's symptoms appear at the intersection of this mechanism and this pattern."

The core of this mapping is its ability to answer the patient's question: "Why am I suffering when the tests are normal?" While CT or MRI may not show structural ruptures in the brain, functional damage to microvessels, axons, ion channels, mitochondria, and autonomic networks is real. Korean medicine captures this through the language of pattern identification: "Blood Stasis, Qi Deficiency, Yin Deficiency, Phlegm-Dampness, and Unsettled Heart-Spirit." In other words, it reads damage that objective imaging cannot see through subjective symptoms, pulse, tongue (舌), and abdominal diagnosis (腹診).

From an integrated perspective, concussion sequelae progress through a flow of "Injury → Inflammation/Metabolic Disturbance → Residual Blood Stasis/Qi and Blood Depletion → Zang-Fu Dysfunction → Symptom Fixation." Immediately after trauma, Blood Stasis and Heat (熱) are central; as time passes, Qi and Blood Deficiency and Yin Deficiency (陰虛) are added. When the condition becomes chronic, Phlegm-Dampness (痰濕) and Unsettled Heart-Spirit intervene, complicating the symptoms. Understanding this flow allows for strategies such as clearing Heat and Blood Stasis in the early stage, supplementing Qi and Blood in the middle stage, and drying Phlegm-Dampness and stabilizing the Heart-Spirit in the chronic stage.

Furthermore, even with the same trauma, the pattern identification varies according to the individual's constitution, age, and comorbidities. In young, active patients, Stagnant Heat Obstructing Collaterals and Hyperactivity of Liver Yang tend to be prominent; in middle-aged women, Qi and Blood Deficiency and Unsettled Heart-Spirit; and in the elderly, Qi Deficiency with Blood Stasis and Liver-Kidney Yin Deficiency. This is the meaning of pattern-based personalization emphasized in Korean medicine. It is an approach that identifies which mechanism or pattern stage the individual's current state is in and induces recovery from that point, rather than standardized symptom suppression.

Synergy is created in this way when combining modern medicine and Korean medicine. Modern medicine rules out acute danger signs, retrains functional circuits through vestibular, visual, and cognitive rehabilitation, and stabilizes symptoms with emotional or sleep medications when necessary. Korean medicine adds Qi and Blood circulation, antioxidant, anti-inflammatory, and autonomic regulation to improve the brain's innate recovery environment. The two are not in competition but are responsible for different layers of the same recovery process.

Ultimately, the goal of integration is to shift from "suppressing symptoms" to "restoring the internal environment so the brain can recover on its own." This is the direction of fundamental recovery pursued by Baekrokdam Korean Medicine Clinic.

Integrated Pathophysiological Flowchart

Integrative Medicine Treatment Approach

The integrative medicine treatment approach begins with two principles. First, post-concussion syndrome is not a single disease but a multidimensional problem involving the brain, neck, vestibular system, vision, emotions, and sleep; therefore, modern medicine and Korean medicine should share the burden based on their respective strengths. Second, Korean medicine aims not only to suppress symptoms but also to restore the body's self-healing power through the circulation of Qi and Blood (氣血) and the recovery of brain function. Under these principles, treatment decisions are made by distinguishing between when modern medicine takes the lead and when Korean medicine provides supplementation, depending on the timing, severity, and red flags of the symptoms.

1. Referral Junction: When and Which Lens Takes Priority

In the acute phase, the priority is for modern medicine to prevent secondary brain damage and create a safe recovery window. During this period, Korean medicine plays a supportive role in aiding cerebral blood flow, inflammation, and sleep without providing excessive stimulation. As the condition transitions into the chronic phase, Korean medicine pattern identification gains more prominent value. In particular, patients who are told their imaging tests are normal need an explanation for "why it still hurts" and a recovery path; this is where Korean medicine shows strength in patient empathy and treatment design.

2. Korean Medicine Treatment by Pattern Identification: Beyond Symptom Suppression to Fundamental Recovery

Korean medicine treatment for post-concussion syndrome involves categorizing patterns (identification) based on the timing and primary symptoms, then combining appropriate prescriptions, acupuncture/moxibustion, and manual therapies. The core is to resolve Blood Stasis (瘀血), replenish Qi and Blood (氣血), and help ensure a smooth supply of nutrients to the brain.

• Blood Stasis Obstruction (瘀血阻滯) / Blood Heat Obstructing the Collaterals (瘀熱阻絡): This applies when there is a stabbing headache persisting from the early stages to the chronic phase, pain that worsens at night, a dark complexion, or purple spots (瘀點) on the tongue. Clinically, this is linked to cerebral blood flow disorders, microvascular damage, and oxidative inflammatory states. Prescriptions such as Yanghyeol-tongnak-tang (涼血通絡湯) or Seogak-jihwang-tang (犀角地黃湯) are used to cool the heat and unblock the blood vessels, while acupuncture combines cranial/cervical acupoints with distal needling.
• Qi and Blood Deficiency (氣血虛弱): This occurs when fatigue is extreme, symptoms recur with even slight overexertion, memory and concentration are decreased, and appetite or digestion is weak. It is common in chronic or recurrent patients. This corresponds to mitochondrial dysfunction and energy metabolism disorders in modern medicine. Prescriptions like Boyang-hwan-o-tang (補陽還五湯), Gwibi-tang (歸脾湯), or Paljin-tang (八진湯) are used to tonify Qi and Blood and supply nutrients to the brain.
• Liver and Kidney Yin Deficiency (肝腎陰虛): This is accompanied by dizziness, tinnitus, insomnia, night sweats (盜汗), heat in the palms and soles, and irritability. It is linked to neurological hypersensitivity and autonomic imbalance after a concussion. Prescriptions like Cheonma-gu-eum-tang (天麻鉤藤湯), Yukmi-jihwang-hwan (六味地黃丸), or Jihwang-eum-ja (地黃飮子) are used to replenish Liver and Kidney Yin and stabilize the brain.
• Phlegm-Dampness Clouding the Upper Orifices (痰濕上蒙): This applies when the head feels heavy and foggy, accompanied by nausea, vomiting, and a general feeling of heaviness in the body. It is viewed as a state where brain fog overlaps with vestibular and digestive dysfunction. Prescriptions like Banha-baekchul-cheonma-tang (半夏白朮天麻湯) or Ondam-tang (溫膽湯) are used to resolve phlegm-dampness and raise the "Clear Yang" (清陽).
• Unsettled Heart-Spirit (心神不安): This involves anxiety, insomnia, palpitations, emotional instability, and being easily startled by small sounds. Post-traumatic stress responses and sleep disorders are the primary pathways. Prescriptions like Gammaek-daejo-tang (甘麥大棗湯), Cheonwang-bosim-dan (天王補心丹), or Sanjoin-tang (酸棗仁湯) are used to stabilize the mind and spirit and restore sleep quality.

In actual clinical practice, these patterns often overlap (two or three at a time) rather than appearing in isolation. For example, Blood Stasis may remain on top of Qi and Blood Deficiency, or Phlegm-Dampness may be accompanied by an Unsettled Heart-Spirit. Therefore, rather than using fixed formulas, it is important to adjust prescriptions by judging the primary and secondary patterns.

3. Modern Evidence and Mechanisms of Action for Korean Medicine Intervention

Recent research is increasingly confirming that Korean medicine treatment is not merely experiential medicine. In a three-arm randomized controlled trial on acupuncture, the verum acupuncture group showed a significant decrease in PCS scores compared to the control and waiting-list groups, and MRI results showed that improvements in brain white matter microstructure were associated with symptom improvement.^[1] A meta-analysis on herbal medicine found that it was effective as an adjunctive therapy for improving functional outcomes and clinical symptoms of traumatic brain injury with few side effects.^[2] Additionally, a mixture of Boswellia and ginger showed effectiveness in improving memory impairment after mild traumatic brain injury.^[3]

Suggested mechanisms for these effects include antioxidant and anti-inflammatory actions, mitochondrial protection, BDNF upregulation, improvement of cerebral blood flow, and regulation of autonomic balance. In other words, Korean medicine prescriptions and acupuncture can act multi-dimensionally on the core pathophysiological pathways of post-concussion syndrome identified by modern medicine—oxidative stress, inflammation, energy metabolism disorders, and axonal/synaptic damage.

4. Integration with Modern Medicine: How Western and Korean Medicine Work Side-by-Side

Integrative medicine is not about simply listing Western and Korean medicine side-by-side, but about simultaneously addressing different layers of the same patient.

• Acute Phase (Within 2 weeks post-accident): Neurological evaluation and exclusion of structural abnormalities come first. During this period, Korean medicine intervenes with mild acupuncture and prescriptions that aid sleep, digestion, and emotions rather than strong blood-invigorating formulas. This is because excessive stimulation can be counterproductive while secondary brain damage is still progressing.
• Subacute to Chronic Phase (2 weeks to >3 months): Korean medicine pattern identification treatment begins in earnest alongside modern medicine's vestibular rehabilitation therapy (VRT), visual processing training, cognitive rehabilitation, CBT, and sleep therapy. For patients where headache is the primary symptom, acupuncture and herbal medicine are used to regulate cerebral blood flow and muscle tension; for those where dizziness is primary, vestibular rehabilitation is linked with Chuna manual therapy.
• Recurrent/Chronic Fatigue Type: Functional medicine approaches are combined with Korean medicine treatments for Qi and Blood Deficiency and Liver-Kidney Yin Deficiency. Fundamental constitution is restored through herbal medicine alongside mitochondrial functional support (magnesium, zinc, omega-3, CoQ10, etc.), sleep hygiene, and exercise prescriptions.

5. Difference Between Fundamental Recovery and Symptom Suppression

Standard modern medical treatment primarily proceeds in a direction that alleviates symptoms and aids functional recovery. This involves using analgesics for headaches, vestibular rehabilitation for dizziness, and sedatives or antidepressants for insomnia. While this is a necessary and important approach, symptoms recur or become chronic for some patients.

Korean medicine offers a different perspective at this point. It aims to correct the scattered Qi (氣) and stagnant Blood (血) caused by trauma and helps ensure that Qi and Blood are smoothly supplied to the brain. The goal is for pain, dizziness, brain fog, and sleep disorders to naturally decrease during this process. In other words, rather than suppressing each individual symptom, it changes the state of the body where symptoms repeatedly arise.

However, Korean medicine is not a panacea. Modern medicine must take the lead for structural problems such as hemorrhage or fractures, severe mental illness, and acute paroxysmal symptoms. Integrative medicine clarifies the boundaries between these two fields and uses the necessary lens at the moment the patient needs it.

Evidence

The evidence base for post-concussion syndrome (PCS) is growing in both modern medicine and Korean medicine, but a definitive single treatment has not yet been established. Modern medicine has identified a significant portion of the pathophysiological mechanisms, while Korean medicine presents clinical research on pattern identification-based approaches that align with these mechanisms. However, it must first be noted that most studies remain at the level of adjunctive therapeutic effects and symptom improvement, and evidence guaranteeing a complete cure is still lacking.

Modern medicine explains the pathophysiology of PCS through ionic and metabolic disturbances, mitochondrial dysfunction, oxidative stress and neuroinflammation, axonal and synaptic damage, autonomic, vestibular, and visual system abnormalities, and neuropsychiatric vicious cycles. Treatment of persistent post-concussion syndrome due to mTBI: current status and future directions (PubMed/NIH) mentions this pathophysiological cascade but points out that most pharmacological and non-pharmacological treatments have failed to demonstrate clear efficacy in both clinical symptoms and pathophysiological processes. This reflects the reality that modern treatments, which focus on symptom suppression, do not always lead to fundamental recovery. Furthermore, Persistent post-concussion syndrome: pathophysiology, diagnosis, current and evolving treatment strategies (PubMed 2025) emphasizes a paradigm shift toward personalized multimodal treatment, which aligns with the pattern identification-based personalized approach of Korean medicine.

Modern medicine is also advancing in terms of diagnosis and evaluation tools. The Rivermead Post-Concussion Symptoms Questionnaire (RPQ), SCAT5, ImPACT, KHIT-6, HIT-6, MoCA-K, and the Pittsburgh Sleep Quality Index are utilized in clinical practice. Advanced imaging such as DTI or fMRI can identify abnormalities in white matter microstructure and functional connectivity networks. However, CT and MRI scans are still frequently normal, leaving a significant gap between the patient's subjective suffering and objective markers.

Evidence from Korean medicine is identified in three areas: acupuncture/moxibustion, herbal medicine, and mechanistic research. Among acupuncture studies, Acupuncture Improves MRI Brain Microstructure with Postconcussion Symptoms in Mild TBI: A Randomized Controlled Trial (PubMed 2025), a three-arm RCT, showed that the verum acupuncture group had a decrease in PCS score of -5.2 ± 6.9 (P=.002), and improvements in MRI microstructure correlated with symptom improvement. A Randomized Exploratory Study to Evaluate Two Acupuncture Methods for TBI-related Headaches (PubMed 2016) also showed a reduction in HIT scores for both auricular and traditional acupuncture. However, Acupuncture for acute management and rehabilitation of TBI (Cochrane 2013) evaluated that a definitive conclusion was not possible due to the low quality of included studies, while a meta-analysis in Acupuncture combined with hyperbaric oxygenation for TBI (Front Neurol 2025) reported that the combination of acupuncture and HBOT was more favorable for functional recovery than HBOT alone.

In herbal medicine research, Herbal Medicine for Traumatic Brain Injury: A Systematic Review and Meta-Analysis of RCTs and Limitations (Front Neurol 2020) evaluated through a meta-analysis of RCTs from 14 databases that herbal medicine is effective as an adjunctive therapy for improving functional outcomes and clinical symptoms of TBI with few side effects. However, it pointed out the risk of bias and prescription heterogeneity as limitations. Effect of a Boswellia and Ginger Mixture on Memory Dysfunction of mTBI Patients (BMC/PMC 2022) and Boswellia serrata extract cognitive benefits in TBI (Brain Injury 2022) showed improvements in memory and cognitive assessments with a mixture of Boswellia and ginger. Domestically, A Case Report of Modified Seogakjihwang-tang for Headache and Memory Impairment after TBI (J Int Korean Med 2013) reported cases of improvement in MMSE-K, MoCA-K, and Mini-Memory Test scores.

Mechanistic research suggests that Korean medicine interventions may act through pathways such as antioxidant and anti-inflammatory effects, mitochondrial protection, BDNF upregulation, white matter microstructure recovery, and improvement of cerebral blood flow and metabolism. Components such as curcumin, Boswellia, and ginger can contribute to functional improvement after TBI by inhibiting TNF-α, IL-6, and NF-κB and activating Nrf2, while electroacupuncture can contribute through the inhibition of HDAC overexpression and regulation of BDNF-Akt/GSK-3β signaling. These mechanisms align precisely with the oxidative stress, inflammation, and mitochondrial damage cascades identified by modern medicine.

Domestic clinical cases in Korean medicine also report approaches to post-concussion syndrome. A Case Report of a PCS Inpatient at Jaseng Hospital of Korean Medicine showed a decrease in KHIT-6 and NRS scores through a combination of herbal medicine, acupuncture, and Chuna manual therapy. A Case Report of PCS at Dongsuwon Korean Medicine Hospital reported a reduction in headache and nausea using acupuncture combined with refined forms of Oryeong-san and Hwangnyeonhaedok-tang. A Case of Diffuse Axonal Injury (DAI) showed improvement in MMSE-K from 13 to 23 points and GDS from 5 to 4 points with herbal medicine and acupuncture. While these are single case reports and cannot be generalized, they demonstrate the clinical contexts in which Korean medicine approaches are utilized.

Clinical Research Trends of Traditional Chinese Medicine Treatment for Post-concussion Syndrome - Focused on CNKI Search (J Int Korean Med 2021) analyzed 22 clinical studies over 10 years from CNKI, including 19 RCTs, 1 nRCT, and 2 case series. It synthesized that acupuncture, herbal medicine, and combined acupuncture-herbal treatments were used to improve headache, dizziness, nausea, memory, sleep, and emotions. However, it evaluated the level of evidence as limited due to study quality, prescription heterogeneity, and differences in evaluation tools.

As such, modern medicine provides the pathophysiology and diagnostic tools, while Korean medicine offers pattern identification-based personalized treatment and adjunctive therapeutic effects. Neither guarantees a complete cure, but they can address different layers of recovery. While modern medicine identifies acute red flags and rules out structural damage, Korean medicine can play an adjunctive role in addressing functional decline, subjective symptoms, and residual Qi and Blood disorders. The value of integrative medicine lies in connecting these two lenses according to the stage and pattern identification of each individual patient.

Frequently Asked Questions

Q1. Why do I still have pain when CT and MRI results are normal?

A normal test result means there is no structural damage such as bleeding or fractures; it does not mean that brain function has fully recovered. A concussion progresses through the collapse of neuronal membrane ion channels, mitochondrial energy metabolism disorders, and microscopic damage to axons and synapses. CT or MRI scans cannot capture these microscopic changes. In Korean medicine, this is viewed as a state where "brain Qi (腦氣) is scattered and brain blood (腦血) is blocked, preventing the smooth supply of Qi, blood, and nutrients." In other words, it means that functional, Qi, and blood recovery—which are not captured in imaging—still remains to be addressed.

Q2. How long should I wait? When should I start treatment?

If symptoms persist for more than 2 weeks, or if headaches, dizziness, decreased concentration, or sleep disorders interfere with daily life, an early evaluation is necessary. During the acute phase (1–2 weeks), rest and a gradual return to activity are priorities. However, if symptoms remain for more than 1 to 3 months, it can be considered post-concussion syndrome, and it is meaningful to consider Korean medical intervention from this point onward. Missing the initial window can lead to chronic pain, sleep issues, and emotional problems.

Q3. How does herbal medicine work for post-concussion syndrome?

Herbal medicine prescriptions vary according to pattern identification (辨證). If blood stasis (瘀血) is predominant, prescriptions that aid blood circulation are used; for Qi and blood deficiency (氣血虛弱), tonifying prescriptions; for phlegm-dampness (痰濕), prescriptions to remove dampness and phlegm; and for mental instability, prescriptions that help calm the mind and aid sleep. Modern research has reported mechanisms where herbal medicine components inhibit inflammatory cytokines such as TNF-α and IL-6, reduce oxidative stress, and regulate mitochondrial function and the BDNF pathway.^[4]

Q4. Is acupuncture and moxibustion treatment effective?

Acupuncture and moxibustion are being researched as adjunctive interventions for improving symptoms of headache, dizziness, sleep, and emotion in post-concussion syndrome. In a three-arm RCT published in PubMed in 2025, the verum acupuncture group showed a decrease in PCS score by -5.2 ± 6.9, and changes in white matter microstructure on MRI were associated with symptom improvement.^[5] However, the quality and reproducibility of research are still limited, and responses vary depending on the individual's condition.

Q5. Can I receive both Western and Korean medical treatments together?

Collaborative care is possible and, in some cases, recommended. Modern medicine has strengths in excluding and managing brain hemorrhage, fractures, vestibular, visual, and emotional issues. Korean medicine plays a complementary role in functional recovery areas such as Qi and blood circulation, residual headaches, fatigue, sleep, and digestion. However, since herbal medicines can interact with painkillers, anticoagulants, antidepressants, etc., it is necessary to disclose all medications and supplements being taken and share this information among medical staff.

Q6. Is a complete cure difficult? How long does it take?

The goal for post-concussion syndrome is remission and functional recovery rather than a complete cure. The duration of symptoms varies greatly from person to person. In young and healthy individuals, improvement may occur within a few weeks, but residual symptoms can persist for months to years. Recurrence is often triggered by fatigue, lack of sleep, stress, and excessive screen exposure. For fundamental recovery, an integrated management approach that cares for Qi and blood circulation, sleep, vestibular, visual, and emotional health is needed, rather than an approach that only suppresses symptoms.
