Intracranial pressure (ICP) is the pressure exerted by fluids such as cerebrospinal fluid (CSF) inside the skull and on the brain tissue. ICP is measured in millimeters of mercury ( mmHg ) and at rest, is normally 7–15 mmHg for a supine adult.
The increased pressure causes a rupture of the cranial dura mater, leading to a CSF leak and intracranial hypotension. [46] [47] Patients with a nude nerve root, where the root sleeve is absent, are at increased risk for developing recurrent CSF leaks. [48] Lumbar disc herniation has been reported to cause CSF leaks in at least one case. [49]
Occasionally, the CSF pressure measurement may be normal despite very suggestive symptoms. This may be attributable to the fact that CSF pressure may fluctuate over the course of the normal day. If the suspicion of problems remains high, it may be necessary to perform more long-term monitoring of the ICP by a pressure catheter. [8]
Regulation: CSF allows for the homeostatic regulation of the distribution of substances between cells of the brain, [3] and neuroendocrine factors, to which slight changes can cause problems or damage to the nervous system. For example, high glycine concentration disrupts temperature and blood pressure control, and high CSF pH causes dizziness ...
Normal pressure hydrocephalus (NPH), also called malresorptive hydrocephalus, is a form of communicating hydrocephalus in which excess cerebrospinal fluid (CSF) builds up in the ventricles, leading to normal or slightly elevated cerebrospinal fluid pressure. The fluid build-up causes the ventricles to enlarge and the pressure inside the head to ...
Therefore, the reduced CSF pressure could cause a decrease in Perilymphatic pressure. This could cause secondary endolymphatic hydrops. [42] In addition to the increased hearing loss, there have also been findings of resolved hearing loss after ventriculoperitoneal shunt placement, where there is a release of CSF pressure on the auditory ...

Lymphocytic pleocytosis is an abnormal increase in the amount of lymphocytes in the cerebrospinal fluid (CSF). It is usually considered to be a sign of infection or inflammation within the nervous system , and is encountered in a number of neurological diseases , such as pseudomigraine, Susac's syndrome, and encephalitis.
