Mr. Wang, a 48-year-old taxi driver, faced significant work stress, was a frequent smoker, and suffered from hypertension. Recently, he noticed his steering wheel drifting uncontrollably to one side while driving, accompanied by limb weakness and a stiff tongue. He immediately sought medical attention and was diagnosed with acute cerebral infarction. Fortunately, timely treatment averted a critical outcome.Mr. Wang's case exemplifies classic stroke symptoms. If you suddenly experience body drifting to one side or asymmetry, take it seriously.
Cerebral infarction, also known as ischemic stroke or commonly called a stroke, refers to localized ischemic necrosis or softening of brain tissue due to impaired blood supply. Middle-aged and elderly individuals aged 45-70 are high-risk groups, though recent years have seen a trend toward younger onset.Epidemiological studies indicate that strokes in individuals under 45 account for 10% to 15% of all stroke cases. These younger patients often experience more severe onset and face greater risks. The most common stroke symptoms include limb weakness and slurred speech. When smiling, the patient's mouth may droop on one side, the nasolabial fold may appear shallower, saliva may leak from the drooping side, and they may lose control over their lips and tongue.
Additionally, clinical observations indicate that some patients may exhibit a tendency for the body to "drift" to one side, which can be confused with other conditions and warrants attention.
Hemiballism. This refers to brief, irregular, involuntary movements on one side of the face or limbs, resembling uncontrollable "dancing" as if the patient has no command over their body. Hemiballism primarily results from lesions damaging the contralateral basal ganglia, including the putamen, caudate nucleus, and thalamic nuclei.
Body image disturbance. When the parietal lobe is affected by stroke, patients may perceive the affected limb as non-existent or feel it is not their own. Consequently, they may use only the unaffected side for dressing or movement. Activities like shaving or combing hair may neglect the affected side, resulting in shaving only half the face or combing only one side of the hair. In severe cases, patients may feel the limb is missing or perceive multiple limbs.
Decreased Grip Strength. Due to brain tissue damage, patients may experience sudden weakness in one hand, dropping objects, falling, or inability to lift an arm or leg. Additionally, unilateral or bilateral eyelid drooping, tongue deviation to one side, air leakage when puffing cheeks, or eyes gazing to one side may indicate a stroke.
If these symptoms appear, seek immediate medical attention. For uncertainty, perform self-assessment: 1. Observe in a mirror for asymmetrical forehead wrinkles, mouth drooping, tongue deviation, or inability to lift one side of the body; 2. Stand with feet together, arms extended forward. Close eyes and check for involuntary leaning or falling to one side;3. Extend your left index finger to your chest center. Then use your right index finger to touch your left index finger, followed by your nose tip, repeating this cycle five times. Switch hands and repeat. If you cannot fully extend your fingers, fail to touch your nose tip, experience numbness, dizziness, or unsteadiness during these actions, it may indicate a stroke.Strokes most commonly occur in the early morning. If the above symptoms suddenly appear upon waking or during a quiet state, seek immediate medical attention, preferably at the nearest large tertiary hospital. Brain neurons are highly sensitive to ischemia and hypoxia. Neurons in the core area of a cerebral infarction typically die within 10 minutes of oxygen deprivation, while the surrounding ischemic penumbra dies within approximately 6 hours.Brain neurons are irreplaceable. Once lost, they cause permanent neurological impairment, leading to hemiplegia, aphasia, or even death. Therefore, time is brain tissue, time is nerve cells. If stroke is suspected, every second counts.
