The concept of 'liver wind' in Donguibogam can be understood in a remarkably similar context to what modern medicine calls a transient ischemic attack (TIA), commonly known as a mini-stroke. A transient ischemic attack is a neurological symptom that occurs when the blood supply to the brain is temporarily interrupted, typically resolving on its own within a few minutes to an hour. However, precisely because of this 'temporary recovery', many people tend to take it lightly or dismiss it as simple fatigue. Yet this is a serious warning sign sent by the brain that must never be overlooked.
The primary symptoms of a transient ischemic attack align closely with the description in Donguibogam where 'the tongue curls and one cannot speak'. Modernly, typical presentations include speech disorders where speech suddenly becomes slurred (dysarthria) or understanding and expressing language becomes difficult (aphasia). Beyond this, it can manifest in diverse forms, such as temporary paralysis with weakness or abnormal sensations in one arm or leg, visual field defects like seeing double or experiencing sudden blurred vision in one eye, as well as severe dizziness or loss of balance. All of these symptoms arise when the blood supply to a specific area of the brain is instantaneously reduced.
Our brain can function normally only when continuously supplied with oxygen and glucose. A transient ischemic attack occurs when foreign matter such as cholesterol or a thrombus accumulates in cerebral blood vessels, narrowing them, or when a thrombus dislodges due to cardiac arrhythmia or other issues, blocks a cerebral blood vessel, and then dissolves again. It is similar to debris clogging a water pipe, reducing water flow, and then clearing. The problem is that approximately 10 to 15 percent of patients who experience a transient ischemic attack face a very high risk of progressing to an actual stroke within three months, particularly within the first 48 hours. In severe cases, it is reported that one-third of stroke patients have experienced a transient ischemic attack, making it accurate to view a transient ischemic attack as an 'advance preview of a full-blown stroke'.
Therefore, if symptoms of a transient ischemic attack appear, you must see a neurologist immediately for a thorough examination, even if you have recovered on your own. The brain is signaling directly that this is not a matter solved simply by resting. It is vital to evaluate the condition of cerebral blood vessels and cardiac issues through magnetic resonance imaging, magnetic resonance angiography, carotid ultrasonography, and electrocardiogram examinations, and to take appropriate preventive measures. Alongside lifestyle improvements such as blood pressure control, diabetes management, cholesterol level management, smoking cessation, alcohol moderation, and regular exercise, you must begin medication therapy such as an antithrombotic agent or an anticoagulant if necessary to prevent a full-blown stroke. Please remember that neglecting it under the illusion that 'it got better' can lead to irreversible consequences.
