Cerebrospinal fluid protein 1600mg/L is a more serious cerebrospinal fluid physiological indicators of disorders, usually seen in organic diseases of the central nervous system, the normal value of cerebrospinal fluid protein between 150-450mg/L, as long as more than 450mg/L is a protein elevation, is one of the physiological indicators of central nervous system pathology, the more common diseases are central nervous system infections, meningeal tumors, The more common diseases are CNS infections, meningeal tumors, CNS hemorrhage, including intracerebral hemorrhage and subarachnoid hemorrhage, as well as cerebrospinal fluid circulatory pathway obstruction, which, in either case, is a more serious organic disease. Central nervous system infections include viral meningitis, tuberculous meningoencephalitis, and suppurative meningitis, all of which are curable, while meningeal tumors, most commonly metastatic meningeal carcinomas, have a poorer prognosis, with most patients dying within 2-6 months.
