WebJan 11, 2024 · A CSF leak occurs when cerebrospinal fluid (CSF) escapes from the protective layer surrounding the brain and spinal cord. This is a serious condition that can cause headaches, seizures, or meningitis. WebCSF provides hydromechanical protection of the neuroaxis through two mechanisms. First, CSF acts as a shock absorber, cushioning the brain against the skull. Second, CSF allows the brain and spinal cord to become buoyant, reducing the effective weight of the brain from its normal 1,500 grams to a much lesser 50 grams.
