Patients with cerebral infarction who start talking nonsense can be cured, and some of them may also be left with certain sequelae. If a patient with cerebral infarction speaks nonsense, it is a special kind of disorder of consciousness, which belongs to delirium state and is mainly seen in patients with severe cerebral infarction and large infarction. Patients with large infarcts, such as large hemispheric infarcts, can have sensory-motor impairment of the lateral limbs and speech dysfunction, and in severe cases patients can have disorders of consciousness, including special disorders of consciousness and general disorders of consciousness. General disorders of consciousness include drowsiness, lethargy and coma; specific disorders of consciousness include delirium states and other disorders of consciousness. Specific disorders of consciousness may also occur if the patient has a brainstem infarction, while the patient may experience dizziness, nausea, vomiting, as well as balance disorders and ataxia. Patients usually have cerebral edema and increased intracranial pressure. If the patient has a severe increase in intracranial pressure, it can cause brain herniation and lead to the patient’s death.
