What disease causes cerebral congestion

Middle-aged and elderly people should pay special attention to the symptoms of cerebral infarction in their bodies, because cerebral infarction is a disease with a relatively high mortality rate. Many elderly people die from cerebral ischemic hypoxia caused by cerebral infarction. Therefore, when there is any symptom of cerebral infarction in the body, we should actively take the correct method to treat it. At this time, it is also necessary to understand the disease that causes cerebral infarction.

The specific symptoms of cerebral infarction are as follows:

(1) Patients with thrombosis often have symptoms of transient ischemic attack (TIA) of cerebral infarction before, such as dizziness, vertigo, weakness on one side of the limbs, etc. The onset is slow, often occurring during sleep or quiet time. However, patients with embolus usually have no prodromal symptoms, develop rapidly, and reach a peak within a few minutes.

(2) There are less severe symptoms of cerebral infarction such as impaired consciousness and intracranial hypertension. The main symptoms are signs of focal brain function loss, which vary according to the location of the affected blood and bones: when the middle cerebral artery is occluded, the contralateral complete hemiplegia, sensory impairment, ipsilateral hemianopsia, etc.; when the posterior inferior cerebellar artery is occluded, dizziness, nausea and vomiting, hoarseness, dysphagia, ataxia, decreased superficial sensation of the face on the same side and decreased superficial sensation of the contralateral limbs or mild hemiplegia may occur.

After understanding the symptoms, the causes are also important. The causes of cerebral infarction include the following:

(i) Fatty hyalinization: Arterial fatty degeneration can be found in the lacunar lesions of penetrating arteries with a diameter less than 200 μm. This is one of the causes of cerebral infarction.

(ii) Microaneurysms: commonly seen in patients with chronic hypertension. This can also be one of the causes of cerebral infarction.

(III) Fibrinoid changes: thickening of vascular walls, excessive and segmental dilation of arterioles, destruction of the blood-brain barrier, and plasma exudation. This is also one of the causes of cerebral infarction.

(IV) Arteriolar atherosclerosis: blood vessels with a diameter of 100 to 400 μm, with typical atheromatous arterial stenosis and occlusion. These are also the causes of cerebral infarction.

In short, there are many possible causes of cerebral infarction. I hope these experts’ introductions can help you. Expert tips: There are many causes of cerebral infarction. We need to be careful to avoid contact with these factors to prevent cerebral infarction from endangering our health.

What causes cerebral infarction?

1. Hypertension and diabetes

The risk of cerebral infarction in patients with hypertension is 7 times higher than that in normal people. Therefore, we should pay attention to keeping blood pressure within the normal range to avoid cerebral infarction. The risk of cerebral infarction in diabetic patients is also significantly higher than that in non-diabetic patients.

2. Irregular lifestyle

In addition, an irregular lifestyle, such as staying up late, irregular or unreasonable diet, and excessive work pressure can also lead to cerebral infarction. Sometimes viruses invading cerebral blood vessels may also cause cerebral infarction.

3. Smoking and drinking:

Clinical studies have shown that more than 50% of patients with cerebral infarction have a history of long-term smoking and drinking. Because smoking can cause an increase in the lipid and fibrinogen levels in the blood, and increase blood viscosity. Drinking alcohol will increase the alcohol content in the blood, causing cerebral vasoconstriction and spasm.

Through the above introduction, I hope everyone can have a comprehensive understanding of the symptoms of cerebral infarction, and I also hope that these symptoms of cerebral infarction can help us detect them early. Finally, I wish you all good health. For details, please consult our online experts. Here, I wish all patients a speedy recovery.
