Abstract: BACKGROUND: In recent years, brain organoids have rapidly emerged as a hotspot in neuroscience research; however, no comprehensive analysis of knowledge graphs related to medical research on brain organoid has been conducted.
OBJECTIVE: To conduct a bibliometric analysis of brain organoid medical research and systematically collate research hotspots, emerging trends, and developmental trajectories in this field, thereby providing scholars with a rapid and systematic overview of the current landscape. 
METHODS: Relevant publications on brain organoids from January 1, 2014 to December 31, 2024 were retrieved and analyzed using the Web of Science Core Collection. CiteSpace, Microsoft Office, and Origin software were employed to quantify annual publication volume, country distributions, institutional contributions, author productivity, highly cited literature, and keyword co-occurrence networks. 
RESULTS AND CONCLUSION: The annual publication volume in brain organoid medicine research has demonstrated a rapid growth trajectory. The United States dominated both output and academic influence, with the University of California System emerging as the most prolific institution. While extensive collaborative networks were observed among institutions and intra-team collaborations remained close-knit, inter-team partnerships were limited. The highest-output author was Knoblich J. Since 2021, research hotspots entered an intensive growth phase. Persistent themes included pluripotent stem cells, in vitro models, and culture techniques, while recent frontiers shifted toward choroid plexus, human cortical organoids, and microglia. To conclude, medical research on brain organoids has entered a phase of accelerated innovation characterized by thematic diversity. The establishment of in vitro three-dimensional models remains a central priority. Future research will focus on interdisciplinary integration of organoid culture with bioengineering technologies to optimize model maturity, thereby advancing precision platforms for investigations on regenerative medicine, neurological disorder treatment, and neurophysiological mechanisms.
