Cardiovascular Disease and Dementia: Exploring Intersections, Risks, and Therapeutic Challenges.

Area of Science:

• Neurology
• Cardiology
• Gerontology

Background:

• Cardiovascular disease (CVD) and dementia, including Alzheimer's disease (AD), vascular dementia (VaD), Lewy body dementia (LBD), and frontotemporal dementia (FTD), exhibit a significant bidirectional relationship.
• Established CVD risk factors like hypertension, coronary artery disease, arrhythmia, and diabetes mellitus are strongly associated with an increased incidence of dementia.
• Emerging research suggests that cognitive decline may amplify cardiovascular risks via increased inflammation and impaired autonomic regulation.

Purpose of the Study:

• To review the intricate bidirectional relationship between cardiovascular disease and major dementia subtypes.
• To explore the impact of cardiovascular medications and dementia treatments on each other's respective conditions.
• To highlight the importance of integrated care and lifestyle interventions for managing both CVD and dementia.

Main Methods:

• Comprehensive literature review of existing studies and clinical trials.
• Analysis of research investigating the influence of traditional cardiovascular risk factors on dementia development.
• Examination of studies on the effects of cardiovascular drugs (e.g., antihypertensives, statins) on cognitive function and dementia therapies on cardiovascular health.

Main Results:

• Strong evidence links hypertension, coronary artery disease, arrhythmia, and diabetes to dementia.
• Cognitive decline can worsen cardiovascular health through inflammation and autonomic dysfunction.
• Cardiovascular medications may impact cognitive outcomes, while dementia treatments can affect cardiovascular status.

Conclusions:

• Integrated management strategies are crucial for addressing the intertwined risks of cardiovascular disease and dementia.
• Early identification of individuals at risk for either condition is vital.
• Lifestyle interventions and coordinated care approaches can improve overall patient outcomes and quality of life.
