Looking into the wisdom of the Donguibogam through the lens of modern medicine reveals that sudden speech disorder or physical paralysis symptoms are powerful warning alarms of stroke, such as cerebral infarction or cerebral hemorrhage. Similar to the sudden shifts of 'wind' described in the Donguibogam, a stroke is a serious disease that can strike without notice and upend our lives completely.
In particular, cerebral infarction is a condition in which blood vessels supplying the brain become blocked, halting the supply of oxygen and nutrients to brain cells and resulting in brain injury. If the blood supply is cut off for even a few minutes, brain cells sustain severe damage and struggle to recover. While heart qi stagnation in the Donguibogam signified stress and emotional frustration, in modern medicine chronic diseases such as hypertension, diabetes, hyperlipidemia, and atrial fibrillation damage blood vessels and heighten the risk of forming a thrombus. Smoking, heavy drinking, obesity, and severe stress also exert critical effects on vascular health. All of these act just like wind-heat, clouding and stiffening the vessels to become the main culprits obstructing cerebral blood flow.
The early symptoms of cerebral infarction are diverse and subtle, making them easy to miss. One of the most common symptoms is speech disorder, which manifests in various patterns such as slurred speech (dysarthria), an inability to comprehend speech (receptive aphasia), or an inability to express intended words (expressive aphasia). Just like the stiff tongue described in the Donguibogam, one may feel as if the tongue has stiffened, pronunciation may falter, or intonation may sound abnormal. People may even struggle to recall words when attempting to speak, or say completely unrelated words.
Accompanying symptoms must never be overlooked either. Representative signs include hemiplegia, where strength drains from one arm and leg or sensation turns abnormal; facial palsy where one side of the face becomes crooked; visual disturbance where objects suddenly appear doubled or vision in one eye blurs; severe dizziness or loss of balance; and excruciating headache never experienced before in one's life. These symptoms tend to appear suddenly, and multiple signs often occur simultaneously. In particular, a transient ischemic attack, which appears temporarily and then resolves, is a strong premonitory sign of stroke and demands even closer attention. You must never assume you are safe simply because the symptoms subsided momentarily.
Cerebral infarction is a condition where the golden hour is truly critical. Arriving at a hospital within 3 hours to a maximum of 4.5 hours after symptom onset to receive appropriate treatment minimizes brain injury and reduces sequelae. Just as the Donguibogam warns of the rapid progression of 'wind,' with stroke, time is brain cells from the moment symptoms start. If someone around you displays these signs, calling emergency services immediately without hesitation is paramount. As in the FAST campaign, it is helpful to remember Face (facial palsy), Arm (arm and leg weakness), Speech (speech disorder), and Time (note the time and reach a hospital quickly). When the clinical insights of the Donguibogam meet the scientific diagnosis of modern medicine, it helps us respond wisely to this urgent situation. Attentive care from those around can save a precious life.
