About this Research Topic

Background

Neurodevelopmental disorders (NDDs) are a heterogeneous group of diseases that can result from abnormal brain development and impact a person's capacity for thought, communication, behaviour, and movement. Since we currently lack targeted therapies for NDDs, they constitute a primary public health concern in our society, given that up to 3% of children are affected worldwide. Multiple gene variants associated with NDDs have been identified thanks to recent research and technical developments in genetics. These variations include the whole range of mutations, including inherited and de novo mutations, from single-nucleotide variants (SNVs) to copy number variants (CNVs), and have been discovered in hundreds of distinct genes. However, the vast majority of NDDs still have an unknown origin. Recent studies point to neuroinflammatory mechanisms and/or environmental factors, such as early life adversities, as fundamental aspects in the aetiology of different neurological conditions. To understand more about the biology of these conditions, a multi-disciplinary approach that brings together studies in human and animal models is crucial.

The goal of this Research Topic is to greater understand the behavioural aspects and molecular underpinnings and their implications in NDDs. This Research Topic will aim to collect cutting-edge research studies on NDDs and psychiatric conditions in both human and animal models that examine the molecular mechanisms and pathways affected by neurodevelopmental conditions. These will include known genetic conditions as well as environmental risk factors for NDDs. Furthermore, we will highlight recent findings on inflammatory alterations found in psychiatric conditions as well as their interplay with neuronal and non-neuronal subpopulations. We will additionally consider studies on behavioural alterations in NDDs and their implication for the pathophysiology of NDDs, as well as related psychiatric disorders. A particular focus will be given to early life adversities and their implication for molecular and behavioural alterations in NDDs individuals and animal models. Finally, it will be discussed how these findings might influence the development of new therapeutic strategies.

We welcome Original Research, Case Reports, Methods, Reviews, and other articles addressing the above-mentioned aims. Specifically, we encourage submissions addressing the following topics:

• Novel gene variants associated with NDDs
• Transcriptomic alterations in neuropsychiatric conditions
• Behavioural and molecular alteration in NDDs individuals and models
• Analysis of inflammatory insults in NDDs and psychiatric conditions
• Translational research and novel treatments in NDDs
• Early life adversities in the aetiology of NDDs
• Current challenges in NDDs and psychiatric conditions

Keywords: Neurodevelopmental Disorders, Psychiatric Disorders, Neurobiology, Inflammation, Early-Life Stress, Autism

Frontiers reserves the right to guide an out-of-scope manuscript to a more suitable section or journal at any stage of peer review.

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 it falls 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.
