What is the most serious symptom of cerebral infarction

Cerebral infarction is very harmful to human health. In severe cases, large-area cerebral infarction, cerebellar herniation, etc. may occur. Cerebral infarction is characterized by "four highs and one more", namely, high incidence rate, high disability rate, high recurrence rate and high mortality rate. Although there are various treatments for cerebral infarction, more than half of the patients will still suffer from sequelae such as hemiplegia, aphasia, language disorders, and even coma.

1. Symptoms of severe cerebral infarction

Hemiplegia, hemilimb disorder, hemianopsia, aphasia, coma, etc. The root cause of the above symptoms is the blockage of cerebral arteries by blood clots. If the middle cerebral artery is blocked, the first group of symptoms mentioned above will appear. If the vertebral-basilar artery is blocked, the latter group of symptoms will appear, leading to local cerebral blood flow interruption and ischemia, hypoxia and necrosis of brain tissue. If the motor nervous system controlled by the cranial nerves is affected, corresponding sequelae such as hemiplegia and limb disorders will appear; if the language center controlled by the cranial nerves is affected, it will cause language disorders or even aphasia and other corresponding neurological symptoms and signs.

2. Prognosis of sequelae of severe cerebral infarction

1. Flaccid paralysis: When one side of the limbs continues to be flaccid and without reflexes for 4-5 days, it is often impossible to regain normal function; if the recovery of tendon reflexes is not accompanied by the recovery of voluntary movements, the recovery of valuable motor function is poor.

2. Spasticity of the limbs in spastic paralysis usually becomes obvious 1-3 weeks after onset. The prognosis is generally better than that of flaccid paralysis, but it cannot be finally determined until some voluntary movements appear.

3. Sensory loss rarely occurs alone, but position sense impairment combined with motor dysfunction often makes functional recovery significantly difficult.

4. Expressive aphasia generally has a good prognosis and can be recovered.

5. The prognosis of sensory aphasia is poor. Retraining becomes difficult because the patient cannot understand.

6. The prognosis of complete aphasia is poor.

7. The prognosis of dysgraphia depends on whether the patient can easily write with normal non-dominant hands.

8. Dysarthria is a motor disorder of speech and generally has a good prognosis.

9. Dysphagia almost always improves.

10. Homonymous hemianopsia can be alleviated, but it is permanent.

11. Pseudobulbar palsy rarely recovers.

3. Methods to improve sequelae of cerebral infarction

In order to effectively improve the occurrence of sequelae of cerebral infarction such as hemiplegia and language impairment and reduce the threat of recurrence of the disease, patients should, while adjusting their diet reasonably and performing active and passive training in functional rehabilitation, receive reliable drug treatment, that is, simultaneously addressing blood and vascular lesions, repairing damaged brain cells, protecting undamaged cells, and preventing blood clots from forming again and atherosclerotic plaques from blocking blood vessels again. This treatment should be the key to the recovery of patients with sequelae of cerebral infarction.
