What is Idiopathic Intracranial Hypertension?

Idiopathic intracranial hypertension (IIH), also known as pseudotumor cerebri, is a condition characterized by increased pressure within the skull, leading to symptoms similar to those of a brain tumor. However, in IIH, there is no identifiable tumor or other obvious cause of the increased intracranial pressure. The exact cause of IIH is not fully understood, but it is believed to be associated with factors such as obesity, certain medications, hormonal imbalances, or anatomical abnormalities. Symptoms of IIH may include severe headaches, vision changes, pulsatile tinnitus, nausea, and vomiting. Prompt diagnosis and management are crucial to prevent complications and preserve neurological function.
