Idiopathic Intracranial Hypertension: Management Challenges

IIH is a condition which can lead to chronic headaches and visual loss secondary to raised intracranial pressure (ICP) in the absence of a structural cause in the brain.1 World-wide the incidence and prevalence of idiopathic intracranial hypertension (IIH) has grown, with young obese women most commonly affected. 2-4 In the United Kingdom the incidence grew by 108% between 2002 to 2016 from 3.5 per 100,000 to 7.69 per 100,000 in the female population.3 Within this period there was over 440% rise in admissions to hospital (this included visits to accident and emergency and inpatient admissions),3 this makes IIH a top topic for consensus on how we approach the management of people with IIH.
