Description

Idiopathic intracranial hypertension (IIH) is a neurological disorder characterized by increased pressure within the skull. It is also known as pseudotumor cerebri, which means 'false brain tumor'. The cause of IIH is unknown, but it is thought to be related to an imbalance between the production and absorption of cerebrospinal fluid (CSF). Symptoms of IIH include headaches, vision problems, and pulsatile tinnitus. Treatment typically involves medications to reduce CSF production and/or increase CSF absorption. In some cases, surgery may be necessary to reduce pressure in the skull.
