Abstract
BACKGROUND: The prevalence of unruptured intracranial aneurysms is approximately 3-5%. Subarachnoid hemorrhage caused by rupture of an aneurysm often affects middle-aged people and harbors high morbidity and mortality. The increasing availability of noninvasive imaging techniques over time is accompanied by an increase in the incidental detection of aneurysms. METHODS: The etiology in aneurysm development is heterogeneous. Besides polygenic multifactorial diseases, often triggered by well-established vascular risk factors, monogenic diseases should also be considered. Advances in genetics has helped to identify genes that contribute to the risk of intracranial aneurysm development. CONCLUSION: The genetic basis of intracranial aneurysms shows a broad heterogeneity and complexity. Currently, besides imaging there is no reliable diagnostic test to identify patients who are at higher risk for asymptomatic intracranial aneurysms.
