Idiopathic Intracranial Hypertension (IIH) is a condition characterized by increased pressure within the skull without an identifiable cause. This condition often leads to symptoms such as headaches, vision problems, and ringing in the ears. It is most commonly seen in overweight women of childbearing age, but it can affect anyone. The exact cause of IIH is unknown, but it is believed to be related to an imbalance in the production and absorption of cerebrospinal fluid. Diagnosis typically involves imaging studies like MRI and a lumbar puncture to measure cerebrospinal fluid pressure. Treatment may include weight loss, medications, or, in severe cases, surgery.
