  2. Lymphocytic pleocytosis - Wikipedia

    en.wikipedia.org/wiki/Lymphocytic_pleocytosis

    Under normal conditions, there are usually less than 5 white blood cells per μL of CSF. In a pleocytic setting, the number of lymphocytes can jump to more than 1,000 cells per μL. Increases in lymphocyte count are often accompanied by an increase in cerebrospinal protein concentrations in addition to pleocytosis of other types of white blood ...

  3. Oligoclonal band - Wikipedia

    en.wikipedia.org/wiki/Oligoclonal_band

    Typically for an OCB analysis, the CSF is concentrated and the serum is diluted. After this dilution/concentration prealbumin appears as higher on CSF. Albumin is typically the dominant band on both fluids. Transferrin is another prominent protein on CSF column because its small molecular size easily increases its filtration in to CSF.

  4. Cerebrospinal fluid - Wikipedia

    en.wikipedia.org/wiki/Cerebrospinal_fluid

    Cerebrospinal fluid (CSF) is a clear, colorless body fluid found within the tissue that surrounds the brain and spinal cord of all vertebrates. CSF is produced by specialised ependymal cells in the choroid plexus of the ventricles of the brain, and absorbed in the arachnoid granulations. In humans, there is about 125 mL of CSF at any one time ...

  6. Cerebrospinal fluid flow MRI - Wikipedia

    en.wikipedia.org/wiki/Cerebrospinal_Fluid_Flow_MRI

    Cerebrospinal fluid (CSF) flow MRI is used to assess pulsatile CSF flow both qualitatively and quantitatively. Time-resolved 2D phase-contrast MRI with velocity encoding is the most common method for CSF analysis. [ 1 ]

  7. Glymphatic system - Wikipedia

    en.wikipedia.org/wiki/Glymphatic_system

    Although the first known observations of the CSF date back to Hippocrates (460–375 BCE) and later, to Galen (130–200 CE), its discovery is credited to Emanuel Swedenborg (1688–1772 CE), who, being a devoutly religious man, identified the CSF during his search for the seat of the soul. [22]

  8. Intracranial pressure - Wikipedia

    en.wikipedia.org/wiki/Intracranial_pressure

    For example, an increase in lesion volume (e.g., epidural hematoma) will be compensated by the downward displacement of CSF and venous blood. [24] Additionally, there is some evidence that brain tissue itself may provide an additional buffer for elevated ICP in circumstances of acute intracranial mass effect via cell volume regulation. [25] [26]

  9. Xanthochromia - Wikipedia

    en.wikipedia.org/wiki/Xanthochromia

    Xanthochromia, from the Greek xanthos (ξανθός) "yellow" and chroma (χρώμα) "colour", is the yellowish appearance of cerebrospinal fluid that occurs several hours after bleeding into the subarachnoid space caused by certain medical conditions, most commonly subarachnoid hemorrhage. [1]
