The headache associated with idiopathic intracranial hypertension frequently has a migrainous phenotype. Idiopathic intracranial hypertension (IIH) is a condition where pressure inside your head rises, causing vision problems, headaches and other symptoms. As soon as spinal fluid is removed during the spinal tap, the pressure inside the head decreases, the venous sinuses may widen, and more blood may flow from the brain. Keywords: Idiopathic intracranial hypertension, Papilledema, Optic disc drusen, Transorbital ultrasound Introduction Identification of optic nerve head edema in a young woman with chronic headaches and normal brain im-aging is highly suggestive of idiopathic intracranial hypertension (IIH) [1]. IIH is a disease characterized by elevated ICP and its associated signs and symptoms in an otherwise alert and awake patient, with no apparent cause. All participants received a lifestyle modification program that included weight reduction with a program emphasizing lifestyle management and a low sodium diet. When pressure around the brain is too high it can put pressure on the optic nerve causing it to swell. This may eventually damage the optic nerve, often causing vision loss. High pressure can also damage the nerves that move the eyes, causing double vision. What Causes Idiopathic Intracranial Hypertension? Both cause parts of the brain to stop functioning properly.
