Abstract
BACKGROUND

Cognitive impairment, which manifests as a limited deterioration of specific functions associated with a particular disease, can lead to a general deterioration of the patient’s standard of living. Transcranial magnetic stimulation, a non-invasive neuromodulation technique, is frequently employed to treat cognitive impairment in neuropsychiatric disorders.

AIM

To analyzed the state of international research on neuromodulation methods for treating cognitive impairment between 2014 and 2023, with the aim of exploring the state of research worldwide and the most recent developments in this particular area.

METHODS

Articles and reviews pertaining to neuromodulation methods for cognitive impairment were examined using the web of science database between January 2014 and December 2023. Publications, nations, organizations, writers, journals, citations, and keywords data from the identified studies were systematically analyzed using the CiteSpace 6.3. R1 software.

RESULTS

A total of 2371 documents with 11750 authors and 9461 institutions, with some co-occurrences, were retrieved. The quantity of yearly publications is showing an increasing trend. The United States and China have emerged as important contributors. Among the institutes, Harvard University had the highest number of publications, while Rossi S an author who is frequently cited. Initially, the primary keywords included human motor cortex, placebo-controlled trials, and serotonin reuptake inhibitors. However, the emphasis gradually moved to substance use disorders, supplementary motor areas, neural mechanisms, and exercise.

CONCLUSION

The use of neuromodulation techniques to treat cognitive impairment has drawn interest from academics all around the world. This study revealed hotspots and new trends in the research of transcranial magnetic stimulation as a cognitive impairment rehabilitation treatment. These findings are hold significant potential to guide further research and thus promote transcranial magnetic stimulation as a treatment method for cognitive impairment.

Keywords: Transcranial magnetic stimulation; Cognitive impairment; Bibliometric analysis; Hotspots; Research trends

Core Tip: The study examines 2371 documents from a wide range of writers and institutions around the world, covering a sizable amount of literature between 2014 and 2023. This breadth ensures a comprehensive overview of the field’s evolution and current trends. Through an analysis of submissions from 9461 institutions worldwide, the study offers an international viewpoint on the field of neuromodulation for cognitive impairment research. In addition to highlighting trends, important contributors, and changing research interests, the paper offers a useful overview of global research on neuromodulation techniques for cognitive impairment. The topic is also highly relevant, and the manuscript is well-organized.
