Narcolepsy can be treated with olanzapine, piracetam, and cytarabine to improve brain metabolism, while the etiology should be analyzed for appropriate etiological treatment. Narcolepsy is a disorder of consciousness that can be caused by a variety of diseases: for example, it can occur in patients with cerebrovascular disease, and it can also be caused by infectious diseases of the central nervous system; in addition, it can also be caused by severe craniocerebral trauma. If it is considered to be caused by craniocerebral trauma, it should be promptly treated outside the brain; if it is caused by encephalitis, it should be treated mainly with antiviral therapy, commonly used drugs include acyclovir and ganciclovir; severe encephalitis may cause an increase in intracranial pressure, which can be treated with antihypertensive therapy, commonly used drugs include mannitol and glycerol fructose; if the patient is drowsy to a serious degree, he can also be treated with brain-awakening therapy, and also If the patient is caused by cerebrovascular disease, commonly seen in cerebral hemorrhage and cerebral infarction, patients with cerebral infarction can take oral aspirin for antiplatelet aggregation, and also oral statins, such as simvastatin, resulvastatin and atorvastatin, to regulate lipids and stabilize plaque. Ultra-early, such as when the onset time is within six hours suitable for thrombolysis, intravenous thrombolytic therapy can be performed, while drugs to improve cerebral metabolism and neuroprotective therapy can also be applied; if the patient is considered to have cerebral hemorrhage, he should be promptly hospitalized for comprehensive treatment.
