Acupuncture and Chinese Medicine for Concussions

Written by Marc Wasserman Ph.D. L.Ac.

 

Introduction

A concussion is a traumatic injury which may develop into a variety of acute and chronic symptoms, including pain, dizziness, nausea, cognitive impairment, changes in mood and emotions, fatigue, etc.

To understand how Chinese medicine and acupuncture can be applied in treatment of concussions it is best to look at both the pathophysiological causes of injury as well as the specific symptoms. We’ll consider both in the sections below.

 

Pathophysiology of Concussions and Understanding Chinese Medicine Theory and Treatment

A concussion occurs when impact to the head causes the brain to strike the inside of the skull, impact and torsion forces damage tissue similar to bruising in any other part of the body. Symptoms at this time may include headache, dizziness, nausea or vomiting, cognitive impairment, fainting, visual disturbance, etc. In Chinese medical theory, at this point the injury is referred to as YuXue (blood stasis) with heat pattern. Treatment focuses on promoting clearance of waste products from the area and improving cerebral blood flow. This minimizes inflammation, improves oxygenation of the area and limits damage to the periphery.

Secondary injury occurs over a period of days and weeks, and is due to a variety of causes resulting from the initial injury and ongoing damage repair. The complexity of possible ongoing symptoms is due to the brain’s functional processes and its role in commanding all activities in the body.

Specific pathophysiological causes of symptoms are listed below with treatment considerations from Chinese medicine.

Decreased cerebral blood flow

Restoring healthy circulation to the brain and removal of metabolic waste should be primary focus. By increasing and maintaining healthy circulation we accelerate damage repair and a return to normal functioning. Herbal medicines with this function are classified as “enlivening blood and transforming stasis” (活血化瘀)or “cooling blood heat” (涼血). These include single herbs like ChuanQi, QianCao, CeBaiYe, DangGui, ShaoYao, ChuanXiong, DanShen, etc. ChuanQi, for example, has long been used to treat vascular and cerebrovascular problems and has shown in research to have antioxidant effects(1). Likewise the commonly used combination of ChuanXiong and ChiShao has demonstrated the ability to limit damage from decreased blood circulation to the neurological system (2). This pairing illustrates how the combination is more effective than individual parts, a governing principle in Chinese medicine. In addition to these combinations, other herbs which clear heat and resolve toxicity can be added in small amounts to clear away lactic acid buildup and quiet down inflammation; these include HuangQin, HuangLian, HuangBai, ZhiZi, ShiGao, DaHuang, etc.

Irregular release and reabsorption of neurotransmitters

Damage to brain often results in irregularity in the chemical signaling systems. Depending on the symptoms, (discussed below) irregularity in neurochemistry falls into the categories of “kidney yang deficiency”(腎陽虛) or “spleen deficiency”(脾虛). Formula choices may  include YouGui Wan, JinGuiShenQi Wan, SiNi Tang, GuiPi Tang, GanMaiDaZao Tang, etc.

Poor clearance of waste products through CSF circulation

Concussion forces can also cause disruption to the brain’s waste removal system. This may lead to chronic and/or delayed symptoms(3). This is known as “phleghm-fluid” (痰飲) or “phlegm reversal”(痰逆). Common formula options include WenDan Tang, BanXiaBaiZhuTianMa Tang, etc.

Free radical damage

This can be addressed with numerous herbal medicine formulas as most provide antioxidants. However, focusing treatment on “tonifying qi”(補氣) will encourage healthy cellular metabolism. A good example is the combination of ChuanXiong, HuangQin and DangGui which has shown protective effects on mitochondrial function and cellular respiration in brain cells. (4)

Of course treatment will likely focus on a combination of these pathomechanisms, to simultaneously restore function and prevent further damage.

 

Symptoms of Concussions and How to Treat with Chinese Medicine and Acupuncture

Headaches

In a large study published in 2016, returning soldiers suffering headaches due to traumatic brain injuries were treated with either acupuncture or the usual treatment modalities. Results showed that patients in the acupuncture treatment group had less pain and less impact on day to day life when compared against those in the conventional treatment group. (5)

As for prescribing Chinese medical formulas, there are several types of headache symptoms or patterns, all with differing diagnosis and treatments according to Chinese medical theory. Following is a list of headache pattern diagnosis and associated treatments:

  1. Blood stasis pattern: Moderate headache pain, nausea, dizziness, occasional eye pain and/or dry eyes, etc. This common pattern is frequently associated with concussions and post concussion syndromes, treatment options include SiWu Tang or BaZhen Tang or similar formulas which enliven blood and transform stasis.
  2. Qi Deficiency Pattern: Headache with lightheadedness or feeling of emptiness in the head, fatigue, diminished appetite, shortness of breath, etc. Treatment options include BuZhongYiQi Tang, SiJunZi Tang, XiangShaLiuJunZi Tang, etc.
  3. Hyperactive Liver Qi Pattern: Severe headache pain, with pain focused on the temples or crown of the head, irritability, outbursts of anger, insomnia, etc. A common prescription for this pattern is YiGanSan or ChaiLing Tang.
  4. Kidney Deficiency Pattern: Mild headache pain, light headedness, tinnitus, extreme fatigue, muscle soreness, etc. Treatment options include LiuWeiDiHuang Wan, YouGuiWan, DaSanWuZi Tang, LiZhongWan etc.
  5. Phlegm Reversal Pattern: Headache pain with dizziness, nausea, heaviness of the eyes or inclination to keep eyelids closed, fatigue, and general discomfort. Treatment choices include BanXiaBaiZhuTianMa Tang, WenDan Tang, etc.

Dizziness or Vertigo

Acupuncture has been shown effective in treating dizziness and vertigo in emergency medicine (6). A simple treatment with manual stimulation of points including NeiGuan, ZuSanLi, TaiChong and others may quickly alleviate acute symptoms of dizziness and nausea.

As for prescribing Chinese herbal medicine many of the patterns for dizziness align with those outlined above regarding headaches. They are as follows:

  1. Liver yang rising: Severe dizziness with nausea, tinnitus, alternating sensations of chills and overheating of the body, outbursts of anger and moodiness. A common prescription for this pattern is JiaWeiXiaoYao San.
  2. Insuffinciency of kidney water: Dizziness with tinnitus, fatigue, lethargy, lack of motivation, night sweats, nausea, etc. Common prescriptions include BaWeiDiHuang Wan, GuiLuErXian Jiao, or many of the variations of LiuWeiDiHuang Wan.
  3. Phlegm accumulation and blockage: dizziness with inability to stand up easily, sensation of fullness in the head, difficulty moving, nausea, stuffiness in the chest. This is commonly treated with BanXiaBaiZhuTianMa Tang or WenDan Tang.
  4. Dual deficiency of qi and blood: dizziness with agitation, interrupted sleep or difficulty falling asleep, lack of strength in the extremeties, poor appetite, and loose bowel movements. Possible prescriptions in this case include ShiQuanDaBu Tang, RenShenYangLaoTang, GuiPi Tang, etc.

Nausea or vomiting

In recent years acupuncture has continued to increase in widespread usage for treatment of nausea and vomiting from a variety of causes. While recovering from a concussion, acupuncture may be an effective choice in alleviating acute symptoms of nausea and vomiting. Simple techniques such as self applied acupressure to the NeiGuan point may help quiet sudden occurrences of nausea.

Leaving off digestive and infective causes of nausea we are left with three common patterns for these symptoms, as listed here.

  1. Phlegm-fluid: vomiting following consumption of food and drink, feeling of congestion or stuffiness in the chest, feeling of thirst. Prescriptions might include ErChen Tang, WenDan Tang, XiaoBanXia Tang, etc.
  2. Qi Depression: nausea and vomiting with decreased appetite, fullness of the chest, achiness of the rib cage, intercostal pain, belching, etc. A common prescription is XiaoYao San.
  3. Spleen deficiency: nausea with weakness of the body, fatigue, no desire for food, lack of strength in the body, loose bowel movements. This pattern is often prescribed LiuJunZi Tang or XiangShaLiuJunZi Tang.

Insomnia or Excessive Sleeping

Acupuncture is commonly used for treatment of insomnia. Proposed mechanisms of action include controlling pain, decreasing anxiety through adjustments to hormone secretion and to the sympathetic nervous system, and regulation and improvement of cerebrovascular circulation. A large review study in Korea found acupuncture to be more helpful than conventional methods for treatment of insomnia following a stroke (7). This may also be the case for insomnia following concussions.

Chinese herbal medicine has many common prescriptions including SuanZaoRen Tang a famous formula used for general insomnia without other factors. For symptoms of mild anxiety, palpitations, feeling of stuffiness in the chest, difficulty quieting down the mind we can consider using BanXiaHouPo Tang or WenDan Tang. For severe anxiety, formulas such as JianLing Tang or ZhenGanXiFeng Tang my be preferred.

Depression and Cognitive Impairment

Depression, mood and emotional changes are also not an uncommon occurrence following concussions. The initial trauma may induce irregular secretion of neurotransmitters in affected areas of the brain. For symptoms of depression including sadness, crying, disinterest in activities, and general discomfort of the body, the treatment focuses on tonifying the heart and spleen systems with formulas such as GuiPi Tang, GanMaiDaZao Tang, SiJunZi Tang, etc. This is similar in concept to irregularity in the serotonergic systems.

Other common symptoms include difficulty with mental focus and concentration, memory loss, lack of motivation, fatigue, etc. These mostly fall into the patterns of qi deficiency or kidney yang deficiency. Chinese herbal prescription choices include BuZhongYiQi Tang, LiZhongWan, YouGuiWan, GuiZhiFuZi Tang, etc. This is similar in concept to irregularity in the dopaminergic systems.

Conclusions

Symptoms of concussion are complicated and likewise are the treatments. Nonetheless the various possible symptoms can be classified well within the system of Chinese medical theory allowing for a range of options to restore physical and mental health.
