Cerebrospinal Fluid (CSF) Pressure Change and Headaches

Intracranial pressure (ICP) is derived from the relationship between intracranial volume changes and the ability to compensate for those changes. When compensatory mechanisms are exhausted in response to a significant change in intracranial volume, pathologic changes in ICP can result and often translate into different headache syndromes among other clinical manifestations. Headaches secondary to low and high ICP are discussed here.
