The diagnosis of idiopathic intracranial hypertension (IIH) is suspected when a patient presents with headache, ringing in the ears, blurry or reduced vision, double vision and diminished vision when sitting up from a supine position.  Risk factors which predispose someone to developing IIH such as obesity, use of birth control pills, vitamin A products or certain antibiotics, are also important when considering the diagnosis.  If there is clinically a suspicion for IIH, the neurologist will perform an indepth examination looking for swelling of the optic nerve (within the eye) and an MRI brain to exclude other cause for increased pressure in the brain.  If the MRI brain is negative, a spinal tap is performed looking for increased pressure which confirms the diagnosis.
