Cerebrospinal Fluid: a serum-like fluid that circulates through the ventricles of the brain, the cavity of the spinal cord, and the subarachnoid space. It acts somewhat like a shock absorber for protection. CSF contains proteins and other important chemicals, known as biomarkers, that may indicate the existence of a disease process, such as meningitis.
Cerebrospinal fluid pressure can impact Migraines and headaches. Most commonly, we see CSF pressure discussed in relation to pseudotumor cerebri, aka idiopathic intractranial hypertension (IIH).
