The diagnosis is based on symptoms and a high opening pressure found during a lumbar puncture with no specific cause found on a brain scan. [1] [2] Treatment includes a healthy diet, salt restriction, and exercise. [2] The medication acetazolamide may also be used along with the above measures. [2]
Intracranial hypertension (IH), also called increased ICP (IICP) or raised intracranial pressure (RICP), refers to elevated pressure in the cranium. 20–25 mmHg is the upper limit of normal at which treatment is necessary, though it is common to use 15 mmHg as the threshold for beginning treatment.
Lumbar puncture in a child suspected of having meningitis Increased CSF pressure can indicate congestive heart failure , cerebral edema , subarachnoid hemorrhage , hypo-osmolality resulting from hemodialysis , meningeal inflammation, purulent meningitis or tuberculous meningitis, hydrocephalus , or pseudotumor cerebri .

And while bacterial meningitis can be life-threatening, "early treatment improves outcomes," says Nagata. "The best treatments start with a prompt diagnosis of what is causing the disease," echoes ...
The initial test is usually a lumbar puncture to collect cerebrospinal fluid for analysis. The lumbar puncture in chronic meningitis usually shows a lymphocytic predominant inflammatory pattern, however, some infectious agents such as early tuberculosis meningitis, nocardia or brucella may have an neutrophilic predominant inflammation. [2]
There are no specific signs or symptoms that can indicate meningitis, and a lumbar puncture (spinal tap) to examine the cerebrospinal fluid is recommended for diagnosis. [47] Lumbar puncture is contraindicated if there is a mass in the brain (tumor or abscess) or the intracranial pressure (ICP) is elevated, as it may lead to brain herniation.
The opening fluid pressure in the spinal canal is obtained by performing a lumbar puncture, also known as a spinal tap. Once the pressure is measured, a radiocontrast agent is injected into the spinal fluid. The contrast then diffuses out through the dura sac before leaking through dural holes.
The presence of lymphocytic pleocytosis is generally detected through a lumbar puncture followed by clinical analysis of cerebrospinal fluid. When combined with analysis of the appearance and pressure of the tested CSF, along with measurements for the amount of glucose and proteins present, white blood cell counts can be used to detect or ...
