Objectives: The present study aimed to bibliometrically analyze scientific productions in the field of Broca's aphasia, indexed in Scopus, Web of Science, and PubMed between 1991 and 2025, and to outline the global research landscape in this field.
Methods: A comprehensive bibliometric analysis was conducted on 779 scientific works retrieved from the three databases using the exact keyword "Broca's aphasia." After limiting the search to Psychology, Medicine, and Neuroscience subject areas and removing 564 duplicates, the final dataset was analyzed using R Studio (Bibliometrix package) and VOSviewer. Analytical methods included annual publication trend analysis, citation analysis, keyword co-occurrence mapping, author collaboration network analysis, and identification of top-performing countries, institutions, and journals.
Results: The findings revealed an overall upward trend in scientific output, with an annual growth rate of 0.96% and an average of 22.58 citations per document. The United States was the most prolific country (466 documents), Roelien Bastiaanse was the most active author (33 publications), and Northwestern University was the leading institution (55 publications). APHASIOLOGY was the most productive journal (117 publications). The most cited article was "Language, music, syntax and the brain" (803 citations). The most frequent keyword was "aphasia" (264 occurrences), and the largest research cluster was centered around Bastiaanse R. Peak publication years were 2009 (36 documents) and 2014 (35 documents).
Conclusion: The quantitative analysis demonstrates a steady upward trend in scientific production, confirming the field's growing dynamism. However, the findings should be interpreted considering limitations such as database bias toward English-language journals and the incomplete coverage of the final year (2025) due to indexing lags.
