About this Research Topic

Background

The field of unruptured intracranial aneurysms is a complex and challenging area of research. These aneurysms are often asymptomatic, discovered incidentally during imaging for other medical reasons. When symptoms do occur, they can range from cranial nerve deficits to subarachnoid hemorrhage in the event of an aneurysmal rupture. The risk of rupture is higher for symptomatic aneurysms, making treatment more urgent. However, the symptomatology of unruptured aneurysms remains ambiguous, making diagnosis difficult. Symptoms such as visual dysfunction, oculomotor nerve palsy, unusual headaches, epilepsy, cerebral infarcts, or transient ischemia have been associated with unruptured intracranial aneurysms. Vertigo has also been reported as an initial or coexisting symptom, independent of the aneurysm's location. The cause of these symptoms is often attributed to local mechanical phenomena due to compression of the aneurysm on adjacent tissue, or a hemodynamic pathophysiological theory indicating disturbed blood flow. However, more research is needed to clarify this field.

The goal of this Research Topic is to provide a comprehensive overview of the non-specific symptomatology of unruptured intracranial aneurysms. We aim to shed light on the atypical symptomatology, identify potential warning signs, and possibly establish new symptoms as characteristic ones. Special emphasis will be placed on headaches and vertigo, and the exclusion of any other relevant etiology.

To further our understanding of unruptured intracranial aneurysms, we welcome articles addressing, but not limited to, the following themes:
- The clinical presentation of unruptured intracranial aneurysms;
- The non-specific symptomatology of unruptured intracranial aneurysms;
- The potential warning signs of unruptured intracranial aneurysms;
- The correlation between symptoms and aneurysm characteristics, location, and other clinical parameters;
- The evolution of symptoms after treatment of symptomatic unruptured cerebral aneurysms.

Keywords: Intracranial, Cerebral, Aneurysms, Unruptured, Symptoms, Non-Specific, Atypical Headaches, Vertigo

Frequently asked questions

• What is a Research Topic?

  Frontiers' Research Topics are collaborative hubs built around an emerging theme.Defined, managed, and led by renowned researchers, they bring communities together around a shared area of interest to stimulate collaboration and innovation.

  Unlike section journals, which serve established specialty communities, Research Topics are pioneer hubs, responding to the evolving scientific landscape and catering to new communities.

• Why does Frontiers publish Research Topics? 

  The goal of Frontiers' publishing program is to empower research communities to actively steer the course of scientific publishing. Our program was implemented as a three-part unit with fixed field journals, flexible specialty sections, and dynamically emerging Research Topics, connecting communities of different sizes and maturity.

  Research Topics originate from the scientific community. Many of our Research Topics are suggested by existing editorial board members who have identified critical challenges or areas of interest in their field.

• Why are Research Topics important for journals?

  As an editor, Research Topics will help you build your journal, as well as your community, around emerging, cutting-edge research. As research trailblazers, Research Topics attract high-quality submissions from leading experts all over the world.

  A thriving Research Topic can potentially evolve into a new specialty section if there is sustained interest and a growing community around it.

• How do we ensure the quality of articles within Research Topics?

  Each Research Topic must be approved by the specialty chief editor, and they fall under the editorial oversight of our editorial boards, supported by our in-house research integrity team. The same standards and rigorous peer review processes apply to articles published as part of a Research Topic as for any other article we publish.

    In 2023, 80% of the Research Topics we published were edited or co-edited by our editorial board members, who are already familiar with their journal's scope, ethos, and publishing model. All other topics are guest edited by leaders in their field, each vetted and formally approved by the specialty chief editor.

• What are the benefits of publishing my article in a Research Topic?

  Publishing your article within a Research Topic with other related articles increases its discoverability and visibility, which can lead to more views, downloads, and citations. Research Topics grow dynamically as more published articles are added, causing frequent revisiting, and further visibility.

  As Research Topics are multidisciplinary, they are cross-listed in several fields and section journals – increasing your reach even more and giving you the chance to expand your network and collaborate with researchers in different fields, all focusing on expanding knowledge around the same important topic.

  Our larger Research Topics are also converted into ebooks and receive social media promotion from our digital marketing team.

   
• What types of articles can be published in a Research Topic?

  Frontiers offers multiple article types, but it will depend on the field and section journals in which the Research Topic will be featured. The available article types for a Research Topic will appear in the drop-down menu during the submission process.

• Who leads a Research Topic? 

  A team of guest editors (called topic editors) lead their Research Topic. This editorial team oversees the entire process, from the initial topic proposal to calls for participation, the peer review, and final publications.

  The team may also include topic coordinators, who help the topic editors send calls for participation, liaise with topic editors on abstracts, and support contributing authors. In some cases, they can also be assigned as reviewers.

• What is the role of a topic editor?

  As a topic editor (TE), you will take the lead on all editorial decisions for the Research Topic, starting with defining its scope. This allows you to curate research around a topic that interests you, bring together different perspectives from leading researchers across different fields and shape the future of your field. 

   

  You will choose your team of co-editors, curate a list of potential authors, send calls for participation and oversee the peer review process, accepting or recommending rejection for each manuscript submitted.

• What support will I receive when editing a new Research Topic? 

  As a topic editor, you're supported at every stage by our in-house team. You will be assigned a single point of contact to help you on both editorial and technical matters. Your topic is managed through our user-friendly online platform, and the peer review process is supported by our industry-first AI review assistant (AIRA).

• As a junior researcher, can I be involved in editing a Research Topic? 

  If you’re an early-stage researcher, we will offer you the opportunity to coordinate your topic, with the support of a senior researcher as the topic editor.
