Common heart conditions increase risk of dementia, experts say

Heart failure is a more serious form of heart disease in which the heart becomes too weak to pump enough blood and oxygen to the body's organs. Up to 81% of people with heart failure may have some form of cognitive decline that affects memory, language, or thinking and planning skills, according to a new scientific statement.

“Emerging evidence suggests that the bidirectional relationship between the heart and brain is deeper than we thought,” Testai said in an email. “Vascular risk factors associated with heart disease, such as diabetes, can increase levels of beta-amyloid in the brain, which has been recognized as an important marker of Alzheimer's disease.

“Instead, beta-amyloid is detected in the heart and is associated with cardiac dysfunction,” he said. “These findings suggest a fundamental biochemical connection between the heart and brain.”

Atrial fibrillation, also known as A-fib, is an irregular heartbeat that is often described by many people with symptoms of the heart in the chest “shaking,” “trembling,” or “flip-flopping.”

Atrial fibrillation is Main causes of stroke In the US. Additionally, strokes related to A-fib tend to be “more severe than strokes due to other underlying causes.” According to the U.S. Centers for Disease Control and Prevention.

Microbleeds, small brain bleeds that can cause cognitive decline, are more common in people with atrial fibrillation, according to a new scientific statement. In fact, people with A-fib have a 39% increased risk of memory and thinking problems.

The incidence of atrial fibrillation in the United States is increasing – estimate It is suggested that up to 16 million people will be infected with A-fib by 2050.

Freeman said modern medicine has great drugs, such as statins and cholesterol-lowering drugs, that can prevent or slow the progression of heart disease, especially if detected early. Regular check-ups and taking prescribed medications daily are key to achieving that, he added.

However, there are limits to what drugs can accomplish. For example, aggressively treating high blood pressure may reduce mild cognitive impairment, but not dementia, the AHA statement said.

“Humans are designed to live very differently than we live today, and it's essential that we help people understand how incredibly important lifestyle is,” Freeman said. spoke.

This benefit also applies to people diagnosed with cardiometabolic diseases such as: type 2 diabetes, heart disease and stroke.

High levels of cortisol, the so-called stress hormone, were associated with damage to the parts of the brain that move and manage information. This was discovered in a survey conducted in October 2018. another study Published March 2023 They found that people with high stress levels were 37% more likely to experience cognitive decline.
