How does meningitis affect cerebrospinal fluid?
Close examination of the cerebrospinal fluid: The fluid is normally clear but may be cloudy in people with meningitis. Measurement of the pressure in the subarachnoid space (which contains the cerebrospinal fluid) as the cerebrospinal fluid is withdrawn: Pressure is usually high in meningitis.
