Introduction
Cerebral infarction refers to cerebral infarction (brain梗死). Hemorrhage after cerebral infarction is mainly caused by increased vascular fragility, reperfusion injury, improper use of anticoagulant drugs, hypertension, diabetes, and other factors. After cerebral infarction, the blood vessel walls in the ischemic area may become fragile due to hypoxia, making them prone to bleeding. Blood pressure must be strictly controlled postoperatively, and护理 recommendations provided by the physician should be followed.

Generally, cerebral infarction refers to cerebral infarction. Hemorrhage after cerebral infarction may be caused by increased vascular fragility, reperfusion injury, improper use of anticoagulant drugs, hypertension, diabetes, and other factors. If discomfort occurs, seek medical attention promptly. Detailed analysis is as follows:

1. Increased Vascular Fragility

After cerebral infarction, the blood vessel walls in the ischemic area may become fragile due to hypoxia, making them prone to bleeding. Blood pressure should be strictly controlled postoperatively, and nursing advice provided by the physician should be followed.

2. Reperfusion Injury

When blood supply is restored to the infarcted area, bleeding may occur. Close monitoring of neurological function is necessary, with timely adjustments to the treatment plan.

3. Improper Use of Anticoagulant Drugs

After cerebral infarction, anticoagulant drugs may be used to prevent thrombosis. However, if the dosage is too high or the medication is improperly used, the risk of bleeding may increase. Anticoagulant drugs should be used strictly according to medical instructions, coagulation function should be monitored regularly, and drug dosages should be adjusted based on the patient's condition.

4. Hypertension

Hypertension can be caused by insufficient physical activity, overweight, and other factors. Hypertension causes long-term excessive pressure on blood vessel walls, making them fragile and prone to rupture and bleeding after cerebral infarction. Symptoms may include vomiting and impaired consciousness. Treatment should follow medical advice to use medications such as mannitol injection, nimodipine injection, and atorvastatin calcium tablets.

5. Diabetes

Long-term consumption of high-sugar foods, unhealthy lifestyle habits, and other factors can lead to diabetes. The hyperglycemic state caused by diabetes can damage blood vessels, causing the vessel walls to become thin and fragile, making them prone to rupture and bleeding. Symptoms may include polyuria and weight loss. It is recommended to follow medical instructions for treatment with medications such as metformin tablets, glipizide tablets, and aspart insulin injection.

In daily care, patients should maintain adequate water intake, but excessive drinking should be avoided to prevent worsening of cerebral edema.

Can cerebral infarction be cured?
Stroke does not necessarily result in immediate paralysis. Recovery depends on the size of the lesion, timing of treatment, and individual patient factors. For some patients, if they reach the hospital within the "golden 4.5 hours," intravenous thrombolytic therapy can reopen the blocked blood vessel and reduce the risk of disability. Alteplase and urokinase are commonly used thrombolytic agents. In cases of major vessel occlusion, mechanical thrombectomy may also be performed.

What are the complications of tuberculous meningitis?
Tuberculous meningitis is an inflammatory disease caused by the invasion of Mycobacterium tuberculosis into the meninges. If not treated promptly or if the condition is poorly controlled, it may lead to various complications, primarily including hydrocephalus, cerebral infarction, neurological dysfunction, epileptic seizures, and spread of infection. For patients with tuberculous meningitis, standardized anti-tuberculosis treatment should be initiated as early as possible, along with regular follow-up imaging of the head and monitoring of cerebrospinal fluid parameters.

Under normal circumstances, cerebral angiography can detect diseases such as cerebral artery stenosis, cerebral aneurysm, cerebral vascular malformation, cerebral infarction, and cerebral hemorrhage. If discomfort symptoms occur, it is recommended to seek timely diagnosis and treatment at a正规 hospital. In addition, cerebral angiography may also identify rare cerebrovascular diseases such as Moyamoya disease. Meanwhile, it is important to monitor the patient's vital signs before and after the examination.

Which medications can treat drooling caused by cerebral infarction?
Under normal circumstances, drooling after cerebral infarction is mostly caused by damage to the facial nerve or glossopharyngeal nerve due to the infarction, leading to swallowing dysfunction and reduced coordination of oral muscles. It is often accompanied by symptoms such as facial droop and slurred speech. Patients may take medications such as Cytidine Diphosphate-Choline Sodium tablets, Mecobalamin tablets, Vitamin B1 tablets, Galantamine tablets, and Butylphthalide soft capsules as directed by a physician.
