Frontotemporal lobar degeneration and amyotrophic lateral sclerosis: A bibliometric analysis

This study analyzes the research hotspots and future directions of frontotemporal lobar degeneration (FTLD) and amyotrophic lateral sclerosis.

Relevant literature was searched using the Web of Science database and analyzed using econometric tools such as CiteSpace and VOSviewer.

A total of 145 articles were included in this study, involving 317 research institutions in 31 countries and regions. Acta Neuropathologica is a prominent journal in terms of issuance and influence, and countries such as the United States and Japan, as well as institutions such as the University of Pennsylvania, occupy an important position in the research. The keywords cover various aspects such as disease characteristics and gene mutations; highly-cited literature focuses on TDP-43 protein and C9orf72 gene mutations. Research hotspots include TDP-43 protein disease-driven pathomechanisms, RNA-related studies, clinical manifestations of the disease and genetic studies, etc. In recent years, research focus has shifted to RNA, C9orf72 gene and so on.

To our knowledge, this study is the first econometric evaluation of the FTLD-ALS literature, and although there are limitations such as relying on the number of documents and citation relationships, and a single source of data, it provides a valuable reference for research in this field and helps to promote subsequent research.
