What is a stroke?

2024-11-22

Stroke, clinically also known as cerebrovascular accident or cerebral apoplexy, is an acute cerebrovascular disease characterized primarily by sudden collapse, loss of consciousness, hemiplegia, facial and oral asymmetry, and speech impairment. It is a common and frequently occurring condition among middle-aged and elderly individuals.

　　I. Classification of Stroke

　　Stroke is primarily classified into two major categories: ischemic stroke and hemorrhagic stroke.

　　Ischemic stroke—comprising cerebral infarction and cerebral thrombosis—is caused by blockage of cerebral blood vessels, which prevents blood flow and leads to ischemia and hypoxia in brain tissue, ultimately resulting in necrosis.

　　Hemorrhagic stroke—primarily characterized by cerebral hemorrhage or subarachnoid hemorrhage—is caused by the rupture of cerebral blood vessels, leading to blood flowing into brain tissue or the subarachnoid space and exerting pressure and causing damage to brain tissue.

　　II. Symptoms of Stroke

　　The symptoms of stroke vary widely, and differ depending on the location, extent, and nature of the stroke. Common symptoms include:

　　Facial manifestations: Sudden facial asymmetry and numbness in the face, tongue, and lips.

　　Language barriers: unclear speech, difficulty finding words, difficulty expressing oneself, inability to read, inability to retell information, and inability to understand others' language, among others.

　　Vision problems: blurred vision, double vision, visual field defects, transient blackouts, blindness, and other symptoms such as dizziness, unsteady gait, headache, nausea, and vomiting may also occur.

　　Limb dysfunction: limb weakness, paralysis, numbness, and incontinence of bowel and bladder.

　　Mental abnormalities: Slowed reaction time, memory impairment, and dementia. In severe cases, patients may experience altered consciousness, seizures, coma, and even life-threatening symptoms.

　　III. Etiology of Stroke

　　The causes of stroke are complex and diverse, and primarily include the following aspects:

　　Hypertension is the most common and primary cause of stroke; 93% of patients with cerebral hemorrhage have a history of hypertension.

　　Cardiac diseases—such as endocarditis—may lead to abdominal wall thrombosis, while bradycardia can cause insufficient blood supply to the brain.

　　Unhealthy lifestyle habits—such as long-term smoking, excessive alcohol consumption, staying up late, and overwork—can all increase the risk of stroke.

　　Climate change: Seasonal temperature fluctuations may also trigger strokes.

　　IV. Treatment of Stroke

　　Treatment methods for stroke typically include general care, nutritional support, acupuncture, medication, and surgical intervention.

　　General treatment: Pay attention to getting plenty of rest, maintaining emotional stability, and closely monitoring the patient’s body temperature and blood pressure changes.

　　Nutritional Support: Strengthen nutritional support by consuming more foods rich in vitamins and high in protein, such as tomatoes, cucumbers, and eggs.

　　Acupuncture Treatment: Acupuncture can promote blood circulation, remove blood stasis, and unblock the meridians, thereby facilitating the absorption of cerebral hematoma and alleviating limb dysfunction.

　　Medication treatment: Take antihypertensive drugs, antiplatelet agents, and other medications to improve bleeding, nourish nerves, and prevent the condition from worsening.

　　Surgical Treatment: For patients with severe conditions—such as those with large intracranial hematomas—surgical intervention is necessary, including procedures like craniotomy for hematoma removal.

　　V. Stroke Prevention

　　The key to stroke prevention lies in controlling risk factors such as hypertension and heart disease, while also adopting a healthy lifestyle that includes eating a balanced diet, engaging in moderate physical activity, and quitting smoking and limiting alcohol consumption. In addition, regular medical checkups and screenings are crucial for early detection and management of potential health issues, making them an important part of stroke prevention.

　　Stroke is a serious cerebrovascular disease characterized by high incidence, high disability rate, and high mortality rate. Therefore, we should place great importance on stroke prevention and treatment, raise health awareness, and reduce the risk of stroke.
