Special Issue Information
Dear Colleagues,
The incidence of dementia is increasing at an alarming rate, representing a major modern public health concern. Alzheimer’s disease (AD), a neurodegenerative disorder with a rising incidence among elderly people, is the most common form of dementia and is characterized by progressive cognitive impairment. The precise etiology of AD is not fully clarified but is known to be complex and multifactorial, with a notable overlap between familial and non-familial forms but also with different forms of dementia, e.g., vascular dementia.
AD is characterized by chronic, progressive neurodegeneration, which involves early synaptotoxicity and, only at later stages, overt neuronal loss and associated brain atrophy.
Beyond the conventional Ab- and tau-targeted approaches, current knowledge about the pathophysiology of AD continues to grow and new findings related to synaptic dysfunction and neuroinflammation are the current focus. Particularly, aberrant-activated microglia and neurotoxic astrocytes have been identified, and the involvement of the complement system in synaptic pruning mechanisms and mitochondrial dysfunction appear to be important mediators, all of which may contribute to synaptic loss and cognitive deficits, the hallmarks of AD.
Additionally, the identification of molecular links between Alzheimer’s disease, diabetes mellitus, and other neurodegenerative diseases, is likely to synergistically act in promoting AD pathology, and may help us to understand the early and late molecular mechanisms of AD.
Emerging evidence suggests that bioactive food ingredients (e.g., phytochemicals) may exert beneficial effects on the brain by protecting neurons against stress-induced injury, by suppressing neuroinflammation, and by improving cognitive function. Indeed, certain foods that are particularly rich in bioactive phytochemicals are thought to strongly influence the structure and function of the brain; such foods are commonly referred to as “brain foods”. These bioactives can exert their action by crossing the blood–brain barrier or influencing the brain–gut-microbiome axis. In this regard, the identification of neuroprotective food ingredients, their multiple targets, and their underlying mechanisms of action, has become a promising therapeutic strategy to complement pharmacological interventions for promoting brain health.
In this Special Issue of International Journal of Molecular Sciences, we aim to gather innovative and important findings and updated state-of-the-art research that provide a comprehensive view on the molecular mechanisms mediating the pathogenesis of AD. This a unique opportunity, and we invite you to submit original research articles, review articles, or clinical trials targeting the role of dietary phytochemicals on various aspects related to neurodegenerative disorders like AD, supporting the neuroprotective potential of food bioactive compounds. Detailing the mechanisms and their neurotoxic effects at the molecular level is essential for developing new treatment strategies urgently required to fight this devastating disease.

Manuscript Submission Information
Manuscripts should be submitted online at www.mdpi.com by registering and logging in to this website. Once you are registered, click here to go to the submission form. Manuscripts can be submitted until the deadline. All submissions that pass pre-check are peer-reviewed. Accepted papers will be published continuously in the journal (as soon as accepted) and will be listed together on the special issue website. Research articles, review articles as well as short communications are invited. For planned papers, a title and short abstract (about 100 words) can be sent to the Editorial Office for announcement on this website.
Submitted manuscripts should not have been published previously, nor be under consideration for publication elsewhere (except conference proceedings papers). All manuscripts are thoroughly refereed through a single-blind peer-review process. A guide for authors and other relevant information for submission of manuscripts is available on the Instructions for Authors page. International Journal of Molecular Sciences is an international peer-reviewed open access semimonthly journal published by MDPI.
Please visit the Instructions for Authors page before submitting a manuscript. There is an Article Processing Charge (APC) for publication in this open access journal. For details about the APC please see here. Submitted papers should be well formatted and use good English. Authors may use MDPI's English editing service prior to publication or during author revisions.
