Temporal trends of intracranial hypertension incidence, prevalence and healthcare use


  • The incidence and prevalence of idiopathic intracranial hypertension (IIH) is increasing and is associated with obesity. This has important implications for healthcare professionals and policy makers given IIH-associated comorbidities, complications and healthcare utilisations.

Why this matters

  • IIH is strongly associated with obesity, and obesity is an increasing global burden. It would seem plausible to assume the incidence of IIH and its associated healthcare utilisation is increasing.

  • Large population studies regarding epidemiology, healthcare use and outcomes of people with IIH in Wales are limited.
