High cerebrospinal fluid protein can be described in degrees, as follows: 1, more than every 5g/L, which is a relatively obvious increase, which often suggests more serious diseases, such as tumors, and tumors may also occur in the cerebrospinal fluid circulation obstruction or intravertebral canal occupancy, resulting in cerebrospinal fluid circulation disorders in the spinal cord, very serious demyelination or serious intracranial infections, especially Mycobacterium tuberculosis infection, which can easily produce A very high increase in cerebrospinal fluid protein; 2. 0.75-5g/L is a moderate increase, which is more common in less severe cases of the above-mentioned diseases, where a moderate increase in cerebrospinal fluid protein can be found, and it is important to note that peripheral demyelinating diseases such as Guillain-Barré syndrome can also cause a moderate increase in cerebrospinal fluid protein; 3. -0.45g/L. If it exceeds 0.45g/L, but does not exceed 0.75g/L, the situation is more complicated, or there may be very mild lesions, such as mild encephalitis, mild immune response, mild cerebrovascular disease, which may cause a mild increase in cerebrospinal fluid protein, or it may be normal, so the specific situation should be analyzed.
