Symptoms of cerebral embolism

We also call cerebral embolism cerebral thrombosis. Cerebral embolism usually occurs in the elderly, and once cerebral embolism occurs, it is very troublesome to treat. Therefore, we must correctly diagnose cerebral embolism. To check cerebral embolism, we can use electroencephalogram and CT scan, or cerebral angiography and brain ultrasound to check whether we have cerebral embolism.

In addition to using instruments to diagnose cerebral embolism, we can actually determine whether we have suffered cerebral embolism by looking at some symptoms, so it is also crucial for us to understand the symptoms of cerebral embolism.

examine

1. Electroencephalogram

The two sides are asymmetrical, with the lesion side showing slow waves, low amplitude, and slow alpha rhythm.

2. Cerebral angiography

It can show arterial stenosis, occlusion and abnormal blood vessels around the lesions.

3. Brain Ultrasound

24 hours after the onset of the disease, the midline wave can be seen shifting to the contralateral side.

4. CT scan

A low-density area with reduced absorption value appears in the vascular distribution area of ​​the infarct site.

5. Blood rheology

The viscosity of whole blood increases, platelet aggregation is enhanced, and the length of thrombus in vitro increases.

Symptoms of cerebral embolism:

Before the onset of the disease, the patient had symptoms such as numbness of limbs, difficulty in movement, slurred speech, dizziness, and blurred vision. The disease often occurs during sleep or in the morning. The affected limb is weak or cannot move, speech is slurred or aphasic, and the patient chokes when drinking water. Most patients lose consciousness or have mild impairment. Facial nerve and hypoglossal nerve paralysis, nystagmus, weakened or enhanced muscle tone and abdominal reflexes, positive pathological reflexes, weakened or absent abdominal wall and cremaster reflexes.

Mild symptoms of cerebral thrombosis include inflexibility of limbs on one side, numbness of senses, and aphasia. Severe cases may lead to coma, incontinence, and even death. However, due to different locations of occurrence, the symptoms of cerebral thrombosis are also different.

In the above article, we introduced what cerebral embolism is. We know that cerebral embolism is also called cerebral thrombosis. Cerebral embolism is a disease that is very difficult to treat, so we must do a good job of preventing cerebral embolism. We can use instruments to check whether we have cerebral embolism, or we can judge based on the symptoms of cerebral embolism.
