Cerebrospinal Fluid Pressure Dynamics and the Pulsatile Component of the Translaminar Pressure Gradient
Idiopathic intracranial hypertension (IIH) is a disease characterized by abnormal high intracranial pressure (ICP) with unknown etiology. Factors such as obesity and stenosis of the venous sinus are potentially linked. Symptoms mainly include persistent associated headache, pulsatile tinnitus, vomiting, cranial nerve palsies, and visual disturbances such as photophobia. Response to medical or surgical treatment is variable by patient.
