Cerebral infarction
Causes of Cerebral Infarction
The first reason is due to arteriosclerosis. Under the influence of risk factors such as hypertension, diabetes, and hyperlipidemia, damage occurs to the inner lining of the arteries. A large amount of lipid components are deposited on the arterial walls, eventually forming unstable plaques, leading to the narrowing and even occlusion of the cerebral arteries, thus causing the formation of cerebral thrombosis. The second reason to consider is cardiac causes; if a patient has atrial fibrillation, mural thrombi can form within the heart. These thrombi, once dislodged into the cerebral arteries, can cause cerebral embolism. The third point to note is arterial dissection, which is also a cause of cerebral infarction, and it is relatively common among young people.
The dangers of staying up all night for cerebral infarction
The dangers of staying up late for those with cerebral infarction are significant. Staying up late can easily lead to an increase in blood pressure, which can damage the inner lining of blood vessels, cause cerebral arterial atherosclerosis, and easily lead to ischemic and hypoxic injuries in the brain tissue, resulting in new or aggravated cerebral infarctions. Long-term staying up late can reduce the ejection fraction of the heart, leading to insufficient cerebral blood supply, and easily trigger cerebrovascular diseases. For patients with cerebral infarction, it is generally advised to have regular living habits, avoid staying up late, wake up on time, and also participate in appropriate physical exercise.
Does cerebral infarction require long-term medication?
Patients with cerebral infarction need to take medication long term. Generally, patients with cerebral infarction have underlying diseases such as cerebral arteriosclerosis and hyperlipidemia, or hypertension, hyperlipidemia, and hyperglycemia. Therefore, cerebral infarction patients need long-term medication to control blood pressure, blood lipids, and blood sugar. Additionally, they should take antiplatelet drugs to prevent new thrombus formation and drugs to combat arteriosclerosis to prevent the worsening of cerebral arteriosclerosis and cerebral vascular stenosis. The focus of treatment is also on preventing other blood vessels from blocking, which could lead to a recurrence or worsening of cerebral infarction. Thus, patients with cerebral infarction need long-term medication and regular check-ups during the medication period, including blood tests and liver and kidney function tests, to monitor for any drug-induced liver or kidney damage. If no damage is apparent, they generally need to continue taking medication long-term. (Please take medication under the guidance of a professional physician.)
Is lacunar infarction serious?
Lacunar stroke, with diameters ranging from 2mm to 15mm, may appear minor in scale but results from long-term arteriosclerosis of cerebral blood vessels, leading to ischemia and necrosis in surrounding tissues. Clinically, symptoms can manifest as pure sensory, pure motor, mixed-type numbness in limbs, among other symptoms. Symptoms are generally mild and recovery is likely; however, long-term oral antiplatelet medications like aspirin are required. Additionally, stabilizing plaques with statins in combination with other drugs is essential. It's also important to maintain a low-salt, low-fat diet, and manage conditions like hypertension and diabetes. Therefore, its severity is relatively mild compared to extensive strokes.
Can people with cerebral infarction eat eggs?
For patients with cerebral infarction, it is acceptable to eat egg whites. Egg whites contain abundant amino acids which can enhance the body's resistance and ensure adequate nutrition for the patient. For cerebral infarction, it is advisable to consume fewer egg yolks. Additionally, egg yolks have a relatively high cholesterol content, which is not conducive to controlling blood lipids in patients. Thus, egg whites can be consumed, but egg yolks should be eaten in moderation. Moreover, patients with cerebral infarction should also consume plenty of fresh vegetables and fruits, which are rich in folic acid and can help fight arteriosclerosis. Additionally, it is beneficial to eat foods rich in unsaturated fatty acids, such as some deep-sea fish and olive oil.
What is a cerebral infarction?
Brain infarction is also relatively common in clinical practice, mainly seen in elderly people, generally accompanied by underlying diseases such as hypertension, hyperlipidemia, and diabetes. Brain infarction is primarily caused by the blockage of cerebral blood vessels, leading to necrosis of brain tissue due to ischemia and hypoxia. After a brain infarction occurs, patients should seek medical attention in a timely manner and be admitted to the department of neurology or neurosurgery for systematic drug treatment. If the infarction area is large or a brain herniation has formed, surgical intervention should be considered, such as decompressive craniectomy and lowering intracranial pressure.
How is lacunar infarction treated?
Lacunar stroke is a type of cerebral stroke characterized by lesions smaller than 1.5 cm in diameter. Often, these can be discovered incidentally on a CT or MRI scan in asymptomatic patients. In such cases, it's important to evaluate whether the patient has risk factors such as hypertension or diabetes, and consider the patient's age, smoking, and drinking habits. Further assessments with cranial MRI angiography or other vascular imaging are recommended to clarify the state of the blood vessels and guide treatment. Additionally, some patients may experience an acute onset with symptoms like slurred speech or limb weakness. Although these symptoms might be mild, it is crucial to seek prompt medical attention to assess the blood vessels and guide further treatment based on the physician's physical examination of the patient.
Which department should I go to for a cerebral infarction?
Stroke is caused by blockage or narrowing of blood vessels within the skull, leading to ischemic necrosis of brain tissue and a range of symptoms. Typically, patients with strokes are seen in neurology departments. Of course, the location of the stroke varies, and each patient's clinical presentation is different. If a stroke occurs, a cranial CT scan can provide a clear diagnosis. Clinically, treatment primarily involves dehydration, lowering intracranial pressure, brain protection, and nutritional support. If the patient has a large area of cerebral infarction and high intracranial pressure, they can be seen in neurosurgery, where procedures such as craniotomy decompression may be used to reduce intracranial pressure.
What should be done if the area of cerebral infarction is large?
If a large cerebral infarction occurs, brain edema often peaks within two to three days, and the mortality rate is extremely high. If medical attention is sought within six hours of onset, thrombolytic therapy can be considered. If emergency thrombolysis is exceeded, then only conservative drug treatment is available. For example, mannitol dehydration to reduce intracranial pressure, nourish neurons, protect brain cells, provide nutritional support, etc. After a stroke, it is essential to monitor changes in the patient's consciousness and pupils, dynamically assess the patient’s Glasgow Coma Score, and be aware of various potential complications. Family members should be well-informed about the patient's condition, etc. (Specific medications should be administered under the guidance of a doctor.)
Do you need to take medication for a long time for cerebral infarction?
Brain infarction generally requires long-term medication, and the specific medications to be taken can vary from person to person. Moreover, the choice of medication should be determined by a doctor based on the patient's condition and past risk factors. Brain infarction is a disease caused by multiple factors, with common causes including hypertension. In the case of hypertension, the choice of antihypertensive medication and the duration of treatment should be based on the patient's blood pressure to maintain it within a normal range. There is also a possibility that the condition is due to diabetes, as some diabetic patients are also prone to brain infarction. Such patients may need to use long-term antidiabetic drugs or insulin to control blood sugar. Additionally, antiplatelet medications might be necessary for brain infarction, but whether to use them should also be determined by the doctor based on the patient's specific circumstances. Since medications can have side effects, a comprehensive decision must be made on what drugs to use. (Note: The use of medications should be carried out under the guidance of a professional doctor.)
