Autism and Gut Microbiota: a Bibliometric Study

The study of gut microbiota’s (GM) role in autism spectrum disorder (ASD) is a new and expanding research field, and bibliometric reviews can be very useful to interpret the scientific production and research trends within it. To that end, this work presents a scientometric study on ASD and GM based on 1069 publications, published between 1992 and 2020, that were found in the Web of Science© database. Journal, author, and institution productivity patterns were found using Lotka’s law and Plos One, USA, and University College Cork (Ireland) were the most productive journal, country, and institution, respectively. Keyword analysis revealed a close relationship between GM, brain, and behavior in ASD, making this a novel research field with interdisciplinary implications.
