Health Behaviors and Mild Cognitive Impairment: A Bibliometric Analysis

Similar articles

The relationship between health behaviors and mild cognitive impairment (MCI) has garnered significant global attention, particularly since the early 2000s. This interest has led to a substantial increase in research exploring how lifestyle choices can potentially mitigate cognitive decline and delay the progression from MCI to dementia. This study seeks to comprehensively analyze the existing literature to identify pivotal factors and emerging trends in this domain.

Research Methodology

This bibliometric analysis sourced data from the Science Citation Index and Social Sciences Citation Index sub-databases within the Web of Science Core Collection. Utilizing VOSviewer and CiteSpace software, the researchers analyzed 2,843 articles through co-citation, co-keywords, and clustering techniques. This approach aimed to uncover the current status, significant questions, and potential future directions within the field of health behaviors and MCI.

Findings and Trends

The analysis revealed that interest in the relationship between health behaviors and MCI began in earnest in 2002, with a notable surge in research output occurring in 2014. The United States emerged as the leading contributor, producing over one-third of the total articles (982 out of 2,843). Key journals publishing on this topic include “Journal of Alzheimer’s Disease,” “Neurobiology of Aging,” and “Frontiers in Aging Neuroscience.” High-impact papers often discuss diagnostic criteria, assessment methods, and multifactorial interventions for MCI.

Co-occurrence keyword analysis identified five primary research hotspots: exercise, diet, risk factors and preventive measures for dementia, cognitive decline-related biomarkers, and clinical trials. These areas are crucial for understanding how lifestyle modifications can influence cognitive health in individuals with MCI.

Actionable Insights

• Exercise and physical activity are consistently highlighted as beneficial in slowing cognitive decline in MCI patients.

• Dietary habits, particularly those emphasizing brain-healthy nutrients, are linked to better cognitive outcomes.

• Early identification of risk factors and implementation of preventive measures can significantly delay the onset of dementia.

• Biomarkers related to cognitive decline offer promising avenues for early diagnosis and targeted interventions.

• Clinical trials remain essential for validating the efficacy of various health behavior interventions in MCI management.
