[Idiopathic intracranial hypertension - Swedish consensus guidelines]

Abstract

Idiopathic intracranial hypertension (IIH) is a disorder affecting both the pediatric and adult population. Investigations and treatments may differ considerably. There are no evidence-based guidelines for treatment. During a national multidisciplinary meeting in Stockholm January 2018 IIH experts from several Swedish regions met to discuss how to manage this patient group. These guidelines are based on this meeting and a review of current medical knowledge. To summarize: All patients should be investigated and treated for underlying factors that could be the cause of high intracranial pressure (ICP) (such as obesity, secondary causes such as intracranial tumors or other factors reported to affect ICP). When treating IIH the preservation of vision is crucial. Follow-up depends on visual status. In case of acute risk of visual impairment prompt surgical intervention must be considered. Symptomatic treatment of headache is recommended.
