The Links between Cardiovascular Diseases and Alzheimer's Disease

Area of Science:

• Neuroscience
• Cardiology
• Genetics

Background:

• The etiology of non-inherited Alzheimer's disease (AD) remains elusive, complicating prevention efforts.
• Cardiovascular diseases (CVD) frequently co-occur with AD, suggesting a potential link.
• Inflammation is a common pathological feature in both AD and CVD, potentially driving disease progression.

Purpose of the Study:

• To review current literature on the relationship between cardiovascular diseases and Alzheimer's disease.
• To explore potential mechanistic links and shared risk factors between AD and CVD.
• To identify common risk factors that may inform AD prevention strategies.

Main Methods:

• Literature review of epidemiological and genome-wide association studies.
• Analysis of mechanistic pathways connecting cardiovascular health and neurodegeneration.
• Synthesis of evidence on shared risk factors for AD and CVD.

Main Results:

• Shared risk factors for AD and CVD include hypertension, dyslipidemia, hypercholesterolemia, and hyperhomocysteinemia.
• Genetic factors, such as ApoEε4, are associated with increased risk for both cardiovascular and nervous system diseases.
• Lifestyle factors including diet, physical activity, and microbiota composition influence the risk of developing both AD and CVD.

Conclusions:

• Cardiovascular diseases represent a significant contributing factor to the development and progression of Alzheimer's disease.
• Shared risk factors and inflammatory pathways provide potential targets for novel AD prevention and treatment strategies.
• Further research into the interplay between cardiovascular health and neurodegenerative processes is warranted.
