About this Research Topic

Background

Neuropsychiatric symptoms (NPSs) include but are not limited to psychotic and affective symptoms, agitation, disinhibition, apathy, aberrant motor behavior, appetite and sleep disorders. In older adults, NPSs confer an increased risk towards incident dementia. Moreover, they are related to poorer quality of life, greater dependence and caregiver burden, increased economic and social costs as well as accelerated courses of cognitive and functional decline. Still, in older adults, NPSs often go unnoticed for long periods while even after their identification they are arguably challenging to manage. Standard therapeutic approaches such as pharmaceutical interventions and psychotherapy are either detrimental to cognition themselves (e.g., benzodiazepines and antipsychotics) or simply fail to alter the course of cognitive decline.

This Research Topic aims to explore the associations between NPSs and cognitive impairment in older adults. Although NPSs have been related to steeper cognitive decline, it is not clear whether particular NPSs are associated with impairment in specific cognitive domains. The mapping of the exact correspondence between NPSs and affected cognitive functions could, however, be very useful in everyday clinical practice and dementia research. This knowledge could enhance the understanding of the neurobiological basis of NPSs, facilitate the earlier identification of cognitive impairment through more targeted clinical assessments in individuals with specific NPSs as well as enable the earlier implementation of cognitive interventions aiming at the fortification of specific cognitive functions in individuals with specific NPSs (to preclude or slow down the anticipated course of cognitive decline).

We welcome any types of manuscripts supported by the Journal - original research articles, brief research articles, community case studies, narrative reviews, mini-reviews, systematic reviews, and meta-analyses - pertaining, but not limited to, the following themes:

- The neuropsychological profile and cognitive trajectories of older adults with neuropsychiatric symptoms.
- The functional status and trajectories of older adults with neuropsychiatric symptoms.
- The association of neuropsychiatric symptoms with incident Alzheimer' s and non-Alzheimer' s dementia.
- Independent determinants of cognitive decline and incident dementia in older adults with neuropsychiatric symptoms.
- The management of neuropsychiatric symptoms in cognitively impaired and unimpaired older adults.
- The prevention and management of cognitive decline in older individuals with neuropsychiatric symptoms.

Keywords: psychotic symptoms, affective disorders, alzheimer's disease, mild cognitive impairment, cognitive decline

Important note: All contributions to this Research Topic must be within the scope of the section and journal to which they are submitted, as defined in their mission statements.

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. 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.
