Full Form of IIH
What is IIH?
Idiopathic Intracranial Hypertension (IIH) is a neurological condition characterized by elevated pressure inside the skull without any identifiable cause such as a tumour, infection, or vascular abnormality. Also referred to as pseudotumor cerebri, it predominantly affects women of childbearing age, particularly those who are overweight or obese, and is increasingly being reported among young Indian women. The condition arises when cerebrospinal fluid accumulates around the brain, producing symptoms like severe morning headaches, blurred or double vision, pulsatile tinnitus, nausea, and papilledema visible on fundoscopic examination. In India, awareness of IIH has improved considerably over the last decade, with major neurology and ophthalmology departments in hospitals like AIIMS, NIMHANS, and PGI regularly diagnosing and managing such cases. Diagnosis usually requires brain MRI, MR venography, lumbar puncture to measure opening CSF pressure, and detailed visual field testing. Treatment options include weight reduction, acetazolamide, topiramate, therapeutic lumbar punctures, and surgical interventions like optic nerve sheath fenestration or CSF shunting. For medical aspirants, IIH is a high-yield topic in NEET PG, INI-CET, and final year MBBS neurology examinations.

IIH — frequently asked questions
What is the full form of IIH?
IIH stands for Idiopathic Intracranial Hypertension, a condition marked by increased pressure around the brain without any detectable cause.
What are the common symptoms of IIH?
The most common symptoms include severe headaches, blurred or double vision, pulsatile ringing in the ears, nausea, and swelling of the optic disc called papilledema.
How is Idiopathic Intracranial Hypertension diagnosed?
Diagnosis involves brain MRI, MR venography to rule out venous sinus thrombosis, lumbar puncture showing elevated CSF opening pressure above 25 cm of water, and detailed ophthalmologic evaluation.
Is IIH a serious condition?
Yes, if left untreated IIH can lead to permanent vision loss due to prolonged papilledema, making early diagnosis and regular follow-up with a neurologist and ophthalmologist essential.
