Insights

Blood-brain barrier (BBB) breakdown is an early sign of mild cognitive impairment (MCI). Research on BBB dysfunction in MCI is rapidly growing, with recent trends focusing on inflammation, oxidative stress, and memory. Increased global collaboration is key for future advancements.

Area of Science:

  • Neuroscience
  • Biomedical Research
  • Cognitive Aging

Background:

  • Mild cognitive impairment (MCI) represents a pathological stage between normal aging and dementia.
  • Breakdown of the blood-brain barrier (BBB) is increasingly recognized as an early biomarker for MCI.
  • Understanding the link between BBB dysfunction and MCI is crucial for developing early diagnostic and therapeutic strategies.

Purpose of the Study:

  • To visually analyze literature on MCI caused by BBB dysfunction over the past two decades (2000-2021).
  • To identify collaboration networks, track research trends, and highlight current and future research frontiers in this field.
  • To systematically map the knowledge landscape of BBB dysfunction in MCI.

Main Methods:

  • Bibliometric analysis of 333 publications from the Web of Science database (2000-2021).
  • Utilized VOSviewer for knowledge mapping and CiteSpace for extracting literature information.
  • Keywords used: "mild cognitive impairment" and ("blood-brain barrier" or "neurovascular unit" or "neurovascular coupling").

Main Results:

  • Literature on BBB dysfunction-induced MCI has shown a significant increasing trend since 2013, with over 40 publications annually.
  • The USA, England, China, and Sweden exhibit close international collaboration.
  • Harvard Medical School, Maastricht University, and University of Washington are leading institutions; Abhay P. Sagare is the most published author, and Zlokovic B.V. is the most cited.

Conclusions:

  • Research on BBB dysfunction contributing to MCI is experiencing a boom.
  • Emerging research hotspots include inflammation, oxidative stress, and memory.
  • Enhanced international and inter-institutional cooperation is recommended to advance the field.
