What are the symptoms of death in patients with cerebral infarction?

Patients with severe cerebral infarction are actually facing a great threat to their lives, because once a cerebral infarction occurs, the mortality rate is very high. The symptoms before death of cerebral infarction patients are relatively severe and obvious, such as dizziness, paralysis, vomiting, etc. These may be caused by cerebral infarction, so everyone must pay considerable attention to this disease.

1. Contralateral hemiplegia that appears suddenly and quickly reaches a peak: hemiplegia, homonymous hemianopsia, aphasia, apraxia, vertigo, diplopia, oculomotor paralysis, ataxia, crossed paralysis, pupil abnormality, quadriplegia, difficulty in eating and swallowing, impaired consciousness, and other cerebral artery occlusive syndrome.

2. Most cases are not accompanied by symptoms of intracranial hypertension such as headache and vomiting: Secondary cerebral edema that occurs within a few days after occlusion of larger arteries can worsen symptoms and lead to impaired consciousness. Severe cerebral edema can also cause the risk of fatal brain herniation.

3. Middle cerebral artery and its deep perforating branches: They are most likely to be affected, resulting in contralateral hemiplegia (severe degree), hemiplegia (loss of sensation), homonymous hemianopsia, and aphasia when the dominant hemisphere (usually the left) is affected. Amnesia occurs when the non-dominant hemisphere is affected.

4. Internal carotid artery: It can cause blindness in the ipsilateral eye. Other symptoms are often difficult to distinguish from those that occur after occlusion of the middle cerebral artery and its deep perforating branches.

5. Anterior cerebral artery: uncommon, one side can cause contralateral hemiplegia, manifested as severe lower limbs, mild upper limbs, strong grip reflex and urinary incontinence. Bilateral involvement may cause apathy, confusion, and occasionally mutism and spastic paraplegia.
