The 40 pages that link to Cerebrospinal fluid, each with the reason it gives.

• Central nervous systemRelated: Its circulation cushions and supports central nervous system structures and provides a route for clinical sampling.

• Spinal cordRelated: It surrounds the cord within the meningeal space and helps absorb mechanical shocks.

• Intracranial pressureRelated: Its production, circulation, and displacement alter the volume contributing to intracranial pressure.

• MeningesRelated: The meninges enclose the spaces through which this fluid circulates.

• MeningitisRelated: Infection and inflammatory changes in this fluid help clinicians identify meningitis.

• Spinal anesthesiaRelated: It carries injected medication through the space surrounding spinal nerve roots.

• EncephalitisRelated: Its analysis can reveal infection or inflammation associated with encephalitis.

• NeurosurgeryRelated: Its pathways and pressure shape operations for hydrocephalus and spinal conditions.

• CraniumRelated: It adds a fluid buffer inside the cranium.

• Subarachnoid hemorrhageRelated: Blood mixes with this fluid and can obstruct its circulation or absorption.

• Herpes simplex encephalitisRelated: Its analysis can reveal inflammation and herpesvirus DNA in suspected cases.

• Herpes simplex virus type 1Related: Testing this fluid for HSV-1 DNA helps diagnose encephalitis.

• Bacterial meningitisRelated: Bacteria multiplying in this fluid provoke inflammation throughout the central nervous system.

• Chemoreceptor trigger zoneRelated: The trigger zone can detect substances carried in this fluid as well as in blood.

• Creutzfeldt–Jakob diseaseRelated: Testing it for RT-QuIC can provide strong evidence of prion disease.

• Foramen magnumRelated: It flows through the craniovertebral junction surrounding neural tissue.

• Tau proteinRelated: Tau concentrations and forms in this fluid can serve as disease biomarkers.

• Idiopathic intracranial hypertensionRelated: Pressure in this fluid is elevated in the disorder.

• AcetazolamideRelated: Acetazolamide can reduce cerebrospinal-fluid production, an effect used in selected pressure disorders.

• NeurosyphilisRelated: Testing this fluid can reveal evidence of central nervous system infection.

• Progressive multifocal leukoencephalopathyRelated: JC virus DNA can be detected in this fluid during diagnostic evaluation.

• Glymphatic systemRelated: It enters proposed glymphatic pathways along arteries and exchanges with brain interstitial fluid.

• Chiari malformationRelated: Crowding at the skull base can disrupt its circulation between the brain and spinal canal.

• MacrocephalyRelated: Excess fluid can enlarge the head, especially when cranial sutures remain open.

• SyringomyeliaRelated: Abnormal cerebrospinal-fluid movement can contribute to syrinx formation.

• Subacute sclerosing panencephalitisRelated: Elevated measles-specific antibodies in this fluid support the diagnosis.

• Anti-NMDA receptor encephalitisRelated: Testing this fluid for NMDA-receptor antibodies can support diagnosis.

• Blood–spinal cord barrierRelated: It surrounds the spinal cord, creating a compartment distinct from spinal cord tissue.

• Craniosacral therapyRelated: Practitioners have attributed a palpable rhythm to its circulation.

• Empty sella syndromeRelated: Its pressure and presence in the pituitary fossa contribute to gland compression.

• MedulloblastomaRelated: Tumor cells can spread through this fluid to other parts of the central nervous system.

• Nervous System DiseasesRelated: Fluid analysis can provide evidence of infection, inflammation, or bleeding.

• Primary amoebic meningoencephalitisRelated: Testing this fluid helps identify the intense inflammation associated with PAM.
