    Study Notes

    Hydrocephalus Causes

    • NOT a cause of hydrocephalus: question needs to be answered by a specific option or text

    Cerebrospinal Fluid (CSF) Formation

    • CSF is formed in the choroid plexus of the brain

    CSF Production

    • Normal rate of CSF production: 500-600 mL/day

    Hydrocephalus Types

    • Obstructive hydrocephalus: occurs when there is a blockage in the flow of CSF, typically in the ventricles or aqueducts
    • Non-obstructive hydrocephalus: occurs when there is an imbalance between CSF production and absorption

    Obstructive Hydrocephalus Obstruction Sites

    • Possible sites of obstruction in obstructive hydrocephalus: aqueduct of Sylvius, foramina of Luschka and Magendie, and the cerebral aqueduct
