  2. Hydrocephalus - Wikipedia

    en.wikipedia.org/wiki/Hydrocephalus

    Hydrocephalus can be classified via mechanism into communicating, noncommunicating, ex vacuo, and normal pressure hydrocephalus. Diagnosis is made by physical examination and medical imaging, such as a CT scan. [1] Hydrocephalus is typically treated through surgery. One option is the placement of a shunt system. [1]

  3. Normal pressure hydrocephalus - Wikipedia

    en.wikipedia.org/wiki/Normal_pressure_hydrocephalus

    Hydrocephalus is caused by an imbalance between the amount of fluid produced and its absorption rate. Enlarged ventricles put increased pressure on the adjacent cortical tissue and cause myriad effects in the patient, including distortion of the fibers in the corona radiata. This leads to an increase in intracranial pressure (ICP).

  4. Aqueductal stenosis - Wikipedia

    en.wikipedia.org/wiki/Aqueductal_stenosis

    When a patient has communicating hydrocephalus, the lateral ventricles and medial parts of the temporal lobes expand and compress the aqueduct. As a result, the pressure within the fourth ventricle drops and causes the aqueduct to close more tightly. This in effect could make aqueductal stenosis a byproduct of hydrocephalus. [8]

  5. Subdural hygroma - Wikipedia

    en.wikipedia.org/wiki/Subdural_hygroma

    Subdural hygromas require two conditions in order to occur. First, there must be a separation in the layers of the Meninges of the brain. Second, the resulting subdural space that occurs from the separation of layers must remain uncompressed in order for CSF to accumulate in the subdural space, resulting in the hygroma. [1]

  6. Low pressure hydrocephalus - Wikipedia

    en.wikipedia.org/wiki/Low_pressure_hydrocephalus

    Low-pressure hydrocephalus (LPH) is a condition whereby ventricles are enlarged and the individual experiences severe dementia, inability to walk, and incontinence – despite very low intracranial pressure (ICP). [1] Low pressure hydrocephalus appears to be a more acute form of normal pressure hydrocephalus. If not diagnosed in a timely ...

  7. Cerebral shunt - Wikipedia

    en.wikipedia.org/wiki/Cerebral_shunt

    Craniosynostosis occurs when the sutures of the skull close too early. The result of multiple sutures fusing before the brain stops growing is an increase in ICP leading to hydrocephalus. [17] 0.05% [18] Post-meningitic hydrocephalus The inflammation and scarring caused by meningitis can inhibit CSF absorption. Dandy–Walker syndrome

  8. Intracranial pressure - Wikipedia

    en.wikipedia.org/wiki/Intracranial_pressure

    ICP is measured in millimeters of mercury and at rest, is normally 7–15 mmHg for a supine adult. This equals to 9–20 cmH 2 O , which is a common scale used in lumbar punctures . [ 1 ] The body has various mechanisms by which it keeps the ICP stable, with CSF pressures varying by about 1 mmHg in normal adults through shifts in production and ...

  9. Endoscopic third ventriculostomy - Wikipedia

    en.wikipedia.org/wiki/Endoscopic_third...

    The surgical treatment options for hydrocephalus are, as previously mentioned, implantation of a cerebral shunt and ETV. Especially in the youngest age group (younger than two years of age) it remains uncertain what is the superior treatment modality. Currently, a large international, multicenter study is conducted to address this issue.
