Effect of Major Depressive Disorder on Stroke Risk and Mortality: A Systematic Review.

Area of Science:

• Neuroscience
• Public Health
• Psychiatry

Background:

• Major depressive disorder (MDD) is a prevalent mental health condition with significant public health implications.
• Stroke is a leading cause of death and disability worldwide.
• The relationship between MDD and stroke risk/mortality requires further investigation.

Purpose of the Study:

• To systematically review existing literature on the association between major depressive disorder and stroke risk and mortality.
• To provide insights into the potential impact of MDD on stroke outcomes.
• To highlight the need for further research to elucidate the underlying mechanisms and clinical implications.

Main Methods:

• Systematic review of studies published between July 2002 and July 2022.
• Searches conducted in PubMed, ScienceDirect, and Google Scholar databases.
• Inclusion of one meta-analysis and seven non-randomized studies after rigorous screening and quality assessment.

Main Results:

• A potentially significant association was identified between major depressive disorder and increased stroke risk and mortality.
• The findings suggest a relevant connection between MDD and stroke, impacting public health.
• The review underscores the need for validation and mechanistic studies.

Conclusions:

• The association between MDD and stroke risk/mortality warrants further investigation.
• Understanding this link is crucial for developing targeted stroke prevention strategies.
• Future research should explore mechanisms, influencing variables, and predictive utility compared to traditional risk factors.
