What is the main cause of cerebral infarction?

Under normal circumstances, the main causes of cerebral infarction may include vascular aging due to aging, the impact of unhealthy lifestyle habits, atherosclerosis, hypertension, atrial fibrillation, and more. If sudden symptoms such as dizziness, limb numbness, or slurred speech occur, it is recommended to seek timely treatment at a reputable hospital. Detailed analysis is as follows:

1. Vascular aging due to aging

With aging, cerebral blood vessels gradually age, lose elasticity, narrow in lumen, and increase resistance to blood flow, making cerebral infarction more likely. It is important to maintain moderate exercise in daily life, such as walking or practicing tai chi, to promote blood circulation. At the same time, attention should be paid to supplementing vitamins and minerals to delay vascular aging.

2. Impact of unhealthy lifestyle habits

Long-term smoking, excessive alcohol consumption, high-salt and high-fat diets, lack of exercise, and other unhealthy lifestyle habits can damage the vascular endothelium, accelerate vascular disease, and increase the risk of cerebral infarction. Lifestyle habits should be adjusted timely, including quitting smoking, limiting alcohol intake, eating a light diet, consuming more vegetables and fruits, maintaining regular sleep patterns, and avoiding staying up late.

3. Atherosclerosis

Lipid deposition on the vessel wall forming plaques can cause cerebral vascular stenosis or even occlusion, leading to cerebral ischemia and hypoxia, which may result in cerebral infarction. Under a doctor's guidance, medications such as atorvastatin calcium tablets, rosuvastatin calcium tablets, and simvastatin tablets can be used to stabilize plaques and control blood lipid levels.

4. Hypertension

Long-term hypertension can damage the cerebral vascular endothelium, leading to vascular hardening and narrowing of the lumen, which makes thrombus formation more likely and can cause cerebral infarction. Under a doctor's guidance, medications such as nifedipine controlled-release tablets, irbesartan tablets, and enalapril tablets can be used to control blood pressure, with regular monitoring of blood pressure changes.

5. Atrial fibrillation

During atrial fibrillation, irregular atrial contractions can easily form blood clots. If a clot dislodges and travels through the bloodstream into the cerebral vessels, it can block the vessel and cause cerebral infarction. Under a doctor's guidance, medications such as warfarin sodium tablets, dabigatran etexilate capsules, and rivaroxaban tablets can be used to prevent clot formation. Surgical treatment may be necessary in some cases.

In daily life, it is important to maintain emotional stability and avoid excessive excitement; undergo regular physical examinations to monitor blood pressure, blood lipids, blood glucose, and other indicators; strictly follow medical advice for medication if suffering from underlying diseases, and never stop or change medications without consulting a doctor; engage in appropriate mental activities to exercise brain function.
