Heart health is key in reducing risk of dementia: AHA

A new statement from the American Heart Association (AHA) revealed that heart health plays a critical role in maintaining brain functions as people age. Research from neurology professors at the University of Illinois emphasized that adopting a healthy lifestyle early and managing heart disease risk factors can help prevent cognitive decline.

Heart disease, which affects nearly 130 million Americans, significantly increases the risks of dementia, the study found. Experts highlighted the importance of taking preventive action early in life, sometimes even before birth.

The AHA reported that plaque buildup in arteries can restrict blood flow to the brain, leading to cognitive impairment. According to the findings, having heart disease raises the risk of dementia by 27%, often without clear symptoms.

In the United States, someone suffers a heart attack every 40 seconds. Of those who survive, up to half experience some degree of cognitive decline.

Heart failure poses an even greater threat, with over 80% of patients showing signs of brain impairment. Another heart condition, atrial fibrillation, which is becoming more prevalent, can trigger small brain bleeds, further increasing dementia risk.

Experts estimated that by 2050, as many as 16 million Americans could be affected by atrial fibrillation.

Despite the statistics, experts agree that lifestyle changes can have a significant impact. Maintaining a healthy diet, prioritizing sleep, managing stress and engaging in regular exercise can help reduce heart disease and protect brain health.
