Cerebral obstructive sleep is a disorder of consciousness due to brain injury, including drowsiness, lethargy, or coma, and is mainly seen in patients with large cerebral infarcts or brainstem infarcts. In case of large hemispheric infarction, hemiparesis, hemiplegia, hemiplegia sensory impairment, and hemianopsia can also occur at the same time. In the case of left-sided lesions, speech dysfunction can occur. If the patient has a brainstem infarction, dizziness is usually present, as well as dysphagia, choking on drinking water, and in severe cases, impaired consciousness and paralysis of both lower limbs. Generally patients have cerebral edema and increased intracranial pressure, and the treatment is mainly to improve blood circulation, neurotrophic and anti-platelet aggregation. When there is a consciousness disorder, brain-awakening treatment is given, and the commonly used drugs are brain-awakening Jing and compound musk. When the intracranial pressure increases, it can be given to lower the cranial pressure treatment, commonly used drugs are mannitol and glycerol fructose.
