Post-stroke cognitive impairment: A bibliometric and knowledge-map analysis

Abstract

BACKGROUND:

Post-stroke cognitive impairment (PSCI) has a negative effect on activities of daily living.

OBJECTIVE:

Although a number of studies have been published on PSCI, no quantitative studies have yet been conducted.

METHOD:

CiteSpace and VOSviewer were used to quantitatively analyze PSCI to illustrate the research hotspots and trends in PSCI. All relevant publications were extracted from the Science Citation Index Expanded (SCI-E) of the Web of Science (WoS).

RESULTS:

A total of 6536 articles were included in this study. From 349 in 2010 to 942 in 2020, the number of publications increased dramatically. The USA maintained the top position worldwide and provided a vital influence. Harvard University was considered the leader in research collaboration among all institutions. Stroke was the most popular journal in this sector and Vincent Mok published the most articles in this area. We analyzed the keywords and identified five research hotspot clusters. By summarizing the literature on PSCI, we considered the publication information regarding different countries, institutions, authors and journals.

CONCLUSION:

The mechanism of PSCI is an active hotspot. Cerebral vascular disease, especially white matter lesions, also received more attention.
