Epidemiology, pharmacological treatment and invasive management of idiopathic intracranial hypertension in Austria: a nationwide, hospital-based, controlled analysis of insurance data

The estimated prevalence falls within reported ranges for Central Europe while likely underestimating the prevalence due to reliance on hospital discharge data. Treatment patterns generally reflect guideline-based management, although invasive procedures appear overrepresented because hospital data skew towards severe cases. Bariatric surgery is underutilized in patients with IIH compared to those with obesity alone.
