Abstract

Aim: This article aims to explore the role of the human gut microbiota (GM) in the pathogenesis of neurological, psychiatric, and neurodevelopmental disorders, highlighting its influence on health and disease, and investigating potential therapeutic strategies targeting GM modulation. Materials and Methods: A comprehensive analysis of the gut microbiota’s composition and its interaction with the human body, particularly, its role in neurological and psychiatric conditions, is provided. The review discusses factors influencing GM composition, including birth mode, breastfeeding, diet, medications, and geography. Additionally, it examines the GM’s functions, such as nutrient absorption, immune regulation, and pathogen defense, alongside its interactions with the nervous system through the gut–brain axis, neurotransmitters, and short-chain fatty acids (SCFAs). Results: Alterations in the GM are linked to various disorders, including Parkinson’s disease, multiple sclerosis, depression, schizophrenia, ADHD, and autism. The GM influences cognitive functions, stress responses, and mood regulation. Antibiotic use disrupts GM diversity, increasing the risk of metabolic disorders, obesity, and allergic diseases. Emerging therapies such as probiotics, prebiotics, and microbiota transplantation show promise in modulating the GM and alleviating symptoms of neurological and psychiatric conditions. Conclusions. The modulation of the GM represents a promising approach for personalized treatment strategies. Further research is needed to better understand the underlying mechanisms and to develop targeted therapies aimed at restoring GM balance for improved clinical outcomes.

  • Disruptions in endocrine signaling due to an imbalanced gut microbiome may contribute to ASD-related behaviors and altered feeding patterns.

    “Disruptions in endocrine signaling due to an imbalanced gut microbiome may contribute to ASD-related behaviors and altered feeding patterns [43].”
  • The endocrine pathway serves as a critical link between ASD and the gut-brain axis, primarily through hormone secretion by enteroendocrine cells.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
