What can TCM do for Patients with Stroke?

What can TCM do for Patients with Stroke? WE COMBINE THE WISDOM OF TRADITIONAL CHINESE MEDICINE, MODERN TECHNOLOGY, AND PATIENT-CENTERED CARE FOR YOU TO THRIVE IN TODAY’S FAST-PACED WORLD. Share Stroke is deadly and dreadful Stroke remains the fourth leading cause of death in Singapore and is one of the top contributors of adult disability – 63% of stroke patients have some disability within three months. The silent and deadly nature of stroke, as well as the resulting long-term disability, makes it one of the most dreadful illnesses which everyone fears. Traditional Chinese Medicine (TCM) has been used for many centuries and is still widely used today in many countries (especially south and east Asia) for the treatment and prevention of stroke, complementing conventional western medical care. However, most people are still unaware of the benefits that TCM can offer in the long, arduous process of stroke rehabilitation. This article hopes to shed light on how TCM views stroke, the types of TCM treatments and their benefits in stroke recovery. What is stroke? From a biomedical perspective, stroke occurs when blood supply to the brain is interrupted. This causes brain cells to lose their function, thus leading to the signs and symptoms commonly observed. There are two main types of stroke: Ischaemic stroke occurs due to blockage of the blood vessel, limiting blood flow to the brain. It is the most common type, accounting for 74% of strokes in Singapore. Hemorrhagic stroke occurs due to rupture of a blood vessel, causing bleeding into the brain. This makes up 24% of strokes in Singapore. Please note: all words in Italics mentioned henceforth refer to the TCM organ-system and not the anatomical organ referenced in western medicine. Meanwhile, in TCM theory, stroke is more than just an illness of the brain as it affects the meridians and other organs as well. From TCM perspective, stroke has been thought to be caused by internal and external influences, resulting in disrupted and unsettled flow of Qi and blood in the body which ultimately rush upwards to the head. Knowing and understanding the internal and external factors contributing to the development of stroke enables one to take precautionary actions to reduce the risk of stroke occurrence. Early identification and intervention for stroke It is well-established that timely intervention at the onset of acute stroke is crucial as more brain tissues can be rescued. This translates into saving body functions and better quality of life for the patient in the long run. Therefore, being aware of stroke symptoms and seeking immediate treatment by calling the ambulance is life-saving knowledge which everyone should know. Common symptoms of stroke include: Sudden weakness or numbness of the face, arm or leg, especially on one side of the body Sudden slurring of speech Sudden trouble walking, dizziness, loss of balance or incoordination Sudden severe headache with no known cause Sudden trouble seeing in one or both eyes Stroke prevention from TCM perspective There are two aspects in prevention – fresh occurrence (people who did not have a stroke before) and reoccurrence (people who experienced stroke before). Among the TCM community, it is generally accepted that the five TCM entities associated with stroke are Wind (风), Fire (火), Phlegm (痰), Stagnation/Stasis (瘀) and Deficiency (虚) respectively. The concept of what each entity encompasses and what should be done to mitigate these deficiency, excess, stagnation and imbalance are detailed as below: 1) Deficiency This internal risk factor arises due to Yin deficiency of the Liver and Kidney. As the human body ages, Liver and Kidney Yin decreases (ageing is something that one cannot change). Although natural ageing is non-modifiable, we can cultivate healthy habits to help conserve the Liver and Kidney Yin, such as: Sleeping early at night (before 11 pm) Having sufficient rest by not overworking (long hours under stressful conditions) Eat Yin nourishing food such as deep, green leafy vegetables, cucumber, celery, millet, eggs and fish Avoid fried, grilled food which causes heat and exhausts Yin 2) Fire (Heat) Yin deficiency results in the production of heat that damages Yin, further aggravating Yin deficiency in the body. Late-night sleep and prolonged extremes of emotions such as anger, frustration and stress bring about fire in the Heart and Liver. If left untreated, this pathogenic fire (imbalance in the body) within the body will deplete Yin to an extent of generating Liver Yang and subsequently Liver Wind which predisposes one to stroke. Some simple ways to mitigate the level of heat in the body: Adopting a regular diet of heat clearing food such as lotus seeds and lily bulbs Sleeping early Maintaining a positive and cheerful mindset 3) Phlegm Like Wind, Phlegm is also a TCM pathogenic factor produced in the body and causes many diseases. Eating irregularly or ingesting excess dairy products, rich, fatty and sweet food weakens the Spleen and leads to the production of Phlegm, which predisposes the body to obesity. In TCM theory, Phlegm causes numbness in the extremities, mental clouding, slurred speech or aphasia, and a swollen tongue with a sticky coating. Extreme physical work, including excessive exercise and sports, also weakens the Spleen and can lead to Spleen deficiency, which in turn causes Phlegm. 4) Stagnation/Stasis Qi stagnation can result from either Qi deficiency or stress. Stagnation, in turn, causes Blood stasis which affects the meridians and joints, causing stiffness and pain in the extremities which are commonly experienced by stroke patients. By exercising, keeping active and doing activities which relieve stress, Qi stagnation can improve. Having adequate rest and a well-balanced diet also helps to alleviate Qi deficiency. 5) Wind Wind must not be taken literally as what we feel in the natural environment. In TCM, there is External Wind and Internal Wind. It is believed that Wind causes the sudden loss of self-awareness in an acute stroke attack, and its subsequent hemiplegia. Liver Yang is formed as a result of severe Liver and Kidney Yin deficiency. This Liver Yang will subsequently induce Liver Wind (Internal Wind) which is a causative agent of stroke, coma, mental clouding and paralysis. Internal and External Wind can interact because the second can shape the first. To quell the formation of Internal Wind, it is important to recognize there are different types of Internal Wind which must be differentiated and dealt with accordingly in clinical practice. The most pertinent categories of differentiation of Internal Wind theory are Heat, Phlegm and Qi deficiency. Post-stroke rehabilitation Besides undergoing the standard care pathway for stroke defined by western doctors, patients can also receive TCM treatment as a complementary form of support to maximize recovery.
