Special Issue Information

Dear Colleagues,

In recent years, new findings have revealed that intestinal neural circuits within the enteric nervous system are endowed with molecular mechanisms that monitor and integrate luminal factors, such as diet and microbiota, to regulate most aspects of intestinal physiology, including motility and neurotransmission. Their dysregulation occurs in intestinal diseases with an active inflammatory component, such as inflammatory bowel disease (IBD), diseases that involve neuroplasticity, such as irritable bowel disease (IBS), as well as extragastrointestinal disorders, such as Parkinson's disease and obesity. Changes in the enteric environment and neuronal function are, therefore, considered important in the development of gastrointestinal pathologies and gut–brain signaling disorders. The latter of these are preceded by alterations in the intestinal barrier integrity and enteric glia activation that reverberate to the central nervous system via the gut–brain axis, mirroring similar alterations in the blood–brain barrier properties and central glial activation.

This Special Issue, edited by Dr. Luisa Seguella and Dr. Simona Spampinato, will focus on the current concepts regarding mechanisms by which the brain may perceive intestinal environment changes, how enteric and central neural circuits are influenced by intestinal luminal factors, and the functional roles of the gut–brain axis in the neuronal pathophysiology of GI and extra-GI diseases. Drugs or therapies that specifically target any aspect of this complex scenario are increasingly attractive, and we encourage colleagues within the field of neuroscience to join this Special Issue to highlight the most innovative and effective therapeutic approaches to treat gut–brain axis disorders.

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. Life is an international peer-reviewed open access monthly journal published by MDPI.

Please visit the Instructions for Authors page before submitting a manuscript. The Article Processing Charge (APC) for publication in this open access journal is 2600 CHF (Swiss Francs). 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.

(1) Background: Compelling evidence shows that dietary patterns can slow the rate of cognitive decline, suggesting diet is a promising preventive measure against dementia. (2) Objective: This systematic review summarizes the evidence of three dietary patterns, the Mediterranean diet, the ketogenic diet and the MIND diet, for the prevention of cognitive decline. (3) Methods: A systematic search was conducted in major electronic databases (PubMed, ScienceDirect and Web of Science) up until 31 January 2022, using the key search terms “Mediterranean diet”, “ketogenic diet”, “MIND diet”, “dementia”, “cognition” and “aging”. A statistical analysis was performed using RoB 2 and the Jadad scale to assess the risk of bias and methodological quality in randomized controlled trials. (4) Results: Only RCTs were included in this study; there were eleven studies (n = 2609 participants) of the Mediterranean diet, seven studies (n = 313) of the ketogenic diet and one study (n = 37) of the MIND diet. The participants’ cognitive statuses were normal in seven studies, ten studies included patients with mild cognitive impairments and two studies included Alzheimer’s disease patients. (5) Conclusion: All three dietary interventions have been shown to slow the rate of cognitive decline in the included studies. The Mediterranean diet was shown to be beneficial for global cognition after 10 weeks of adherence, the ketogenic diet had a beneficial effect for patients with diabetes mellitus and improved verbal recognition, while the MIND diet showed benefits in obese patients, improving working memory, verbal recognition, memory and attention.
