Research on the brain-gut axis and psychiatric disorders is growing. This bibliometric analysis reveals key trends, leading countries like China, and hot topics such as depression and probiotic treatments.
Area of Science:
- Neuroscience
- Psychiatry
- Microbiology
Background:
- The brain-gut axis, a bidirectional communication pathway, is crucial in psychiatric disorder development.
- Research trends in this field remain unclear, necessitating a bibliometric overview.
Purpose of the Study:
- To explore and map the research landscape of the brain-gut axis and psychiatric disorders.
- To identify publication patterns, influential contributors, and emerging research themes.
Main Methods:
- Bibliometric analysis of 2,298 articles from 1993-2022 using Web of Science Core Collection.
- Data analysis employed R, VOSviewer, CiteSpace, and an online bibliometric platform.
Main Results:
- Publication output shows a significant increasing trend.
- China is the most prolific country, while Nutrients is the leading journal.
- Key research themes include depression, anxiety, autism, neurodegenerative diseases, and probiotic interventions.
Conclusions:
- Research on the brain-gut axis and psychiatric disorders is rapidly expanding, particularly in high-income countries.
- This study offers insights into current trends, hot topics, and potential research gaps.
