Idiopathic Intracranial Hypertension

Idiopathic intracranial hypertension (IIH) is a neurological condition characterized by increased pressure of the cerebrospinal fluid (CSF) inside the skull without any underlying medical cause. It is also known as pseudotumor cerebri, or benign intracranial hypertension. Patients typically experience headaches, pulsatile tinnitus (ringing in the ears) and vision loss. Other symptoms may include nausea, vomiting and cognitive dysfunction. IIH is commonly diagnosed in young obese women. Treatment includes medications, lifestyle changes and surgery. If left untreated, it can result in permanent vision loss or other complications. Early diagnosis and treatment are essential for a good outcome, making awareness and understanding of IIH of critical importance.
