Background

Neurodegenerative disorders are globally recognized as a major cause of death and disability, gaining increasing attention as laboratory research is translated into clinical work. However, the critical issue of non-identified underlying causes of such disorders still persists. For centuries, humans have consumed different parts and formulations of plant species for the treatment of neurological disorders. Medicinal plants have a range of phytochemicals, with some having promising neuroprotective properties which are documented and demonstrated by numerous research studies. Such plant-derived phytochemicals are diversified groups of bioactive compounds with various classes such as terpenoids, flavonoids, alkaloids, and phenols used as protective agents in nervous system disorders. Although phytochemical therapies are extensively used against neurodegeneration, the underlying mechanism of action is yet to be determined with doubts about phytochemical toxicity and side effect mediation persisting. Interestingly, from 1940 to 2014, 49% of all small molecules approved by the US Food and Drug Administration (FDA) were natural products or their derivatives. This further encourages researchers to understand the underlying neuroprotective mechanism of phytochemicals as it can be vital in determining their use for neurotherapeutic purposes.

This Research Topic aims to present significant evidence of the therapeutic efficacy and potential of phytochemicals in neurological disorders including Alzheimer’s Disease (AD), Parkinson’s Disease (PD), Ischemic Stroke, Hemorrhagic Stroke, Traumatic Brain Injury (TBI), Spinal Cord Injury, Multiple Sclerosis (MS) and Amyotrophic Lateral Sclerosis (ALS). The Research Topic welcomes original research and review papers focused on the use of phytochemicals in improving neurological dysfunctions in preclinical and clinical studies. Research studies carried out using in vivo rodent, nonrodent models to explore the mechanism of action and interaction of phytochemicals with molecular mediators of neurodegeneration can be recommended. We will not accept manuscripts that contain only in vitro experiments or in silico work but will consider manuscripts that have a combination such as in vitro/in silico and in vivo applications to a model of neurological disorders.

The scope and focus areas of the present Research Topic include but are not limited to:
-Neuroprotective mechanisms of phytochemicals on nervous system disorders.
-Delineation of phytochemical interaction with conventional neuroprotective drugs
-Efficacy of natural bioactive compounds in the therapeutic interventions for regulation of Endoplasmic Stress (ER) and autophagy in age-related disorders.
-Neuroprotective mechanisms of phytochemicals in neurodegenerative disorders
-Oxidative stress, mitochondrial dysfunction, and neuroinflammation in neurodegenerative disorders and the therapeutic potential of phytochemicals.

Keywords: Phytochemicals, Neuroprotection, Neuropharmaceutical, Neuropharmacology, Neurological Disorders, Neurodegeneration

Frequently asked questions

  • 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.

  • 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.

  • 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.

  • 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.

  • 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.

     

  • 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.
