Unruptured intracranial aneurysms in Sweden showed an age-standardized incidence rise of about 74% from 4.6 per 100,000 in 2000 to 7.99 per 100,000 in 2019.
- Why it matters: Reliable incidence estimates are needed to support risk stratification, clinical decisions, and public health planning for unruptured intracranial aneurysms.
- What they did: Using the Swedish National Patient Register, the study identified all adults (≥18 years) diagnosed with intracranial aneurysm (ICD-10: I67.1) from 2000–2020, calculating crude and age- and gender-stratified incidence and assessing cases with concurrent SAH.
- The result: Across 8681 diagnosed UIA patients (median age 63; 65.1% women), the increase was most pronounced in women and those older than 60, while SAH-associated cases decreased slightly.
