Want to keep your brain sharp and shielded from the risk of dementia? While Sudoku puzzles and reading are great ways to ward off cognitive decline, the real trick might be in protecting your heart. There is mounting evidence that people with arrhythmias, such as AFib, face an increased risk of cognitive decline. If you or a loved one suffers from memory issues or thinking difficulties, you won’t want to miss this vital information.

The head and the heart

The health of the heart and mind can’t be separated. Connected through a complex web of nerves that encompass the autonomic nervous system, the heart and brain constantly communicate back and forth with one another. So, for example, if the brain observes something frightening happening, the sympathetic nervous system tells the heart to beat faster. This allows more blood flow to areas of the body that might need it, such as the legs, to run away. 

Evidence suggests that poor mental health increases the risk of heart disease. Depression, anxiety, and stress all contribute to cardiac problems. As stress hormones increase, blood vessels constrict, and blood pressure rises, putting additional strain on the heart. Therefore, cultivating a healthy mind helps to ensure a healthy heart. 

While it’s well known that the brain impacts the heart, science is just beginning to realize the effects that the heart also has on the brain. As a result, this bidirectional relationship is starting to get more attention in the field of neurocardiology.  

The aging brain 

We’ve all had instances where we’ve misplaced our car keys or forgotten the name of someone we just met. Unfortunately, most of us get a little more forgetful in our later years. As we age, the brain becomes less efficient at processing information, leading to momentary lapses in memory. However, memory loss, confusion, and difficulty learning new tasks are not part of the normal aging process. Instead, they might be the first signs that something is awry with our health. 

Dementia is a growing problem worldwide, with over 50 million people suffering from the disease. Dementia occurs when there is a decline in cognitive function beyond what is generally expected during the aging process. Alzheimer’s disease, the most common type of dementia, impacts close to six million Americans today. As with cardiac conditions, cognitive disorders are increasing at alarming rates. 

Could AFib be contributing to cognitive decline? 

Atrial fibrillation and dementia share many common risk factors, including age. Therefore, individuals with AFib experiencing cognitive decline often brush it off as part of the normal aging process. However, is it possible that AFib could be causing memory problems?

Multiple studies have demonstrated a link between AFib and cognitive decline. In the most extensive study of its kind, researchers followed 262,211 individuals 60 years and older. While all participants were arrhythmia-free at the start of the study, 10,435 developed AFib during the nine-year investigation. 

Researchers found that individuals who developed AFib were 50 percent more likely to develop dementia than those without AFib. What’s more, the study also found that AFib increased the risk of Alzheimer’s disease by 30 percent. These findings held even after stroke survivors were removed from the study findings. While the scientists could not prove that AFib causes dementia, they did conclude that the arrhythmia is a significant risk factor for cognitive decline. 

How does AFib cause cognitive decline?

Aside from the devastating cognitive effects of a major stroke, the mechanisms by which atrial fibrillation might cause dementia are not entirely clear. Possible causes include: 

  • Decreased blood flow to the brain: AFib impacts the heart’s ability to pump blood efficiently. Studies have found that AFib patients often experience reduced blood flow. As such, individuals with AFib may not be getting enough oxygen and glucose to the brain. Without the proper nutrients, the brain does not have the energy it needs to function. 
  • Silent or mini-strokes: The irregular rhythm of a heart in AFib can cause blood clots. These blood clots can travel to the brain, causing small, unnoticeable strokes. Over time, these silent strokes can lead to dementia. A 2018 study found that four out of every ten patients with AFib had unknown brain damage as seen on an MRI. 
  • Medications: The aging process can change how drugs are absorbed in the body. Certain medications used to treat AFib may contribute to cognitive decline and dementia.
  • Toxins or other underlying causes: AFib generally has a root cause, whether it be from toxin exposure, heavy metals, pathogens, or other issues that lead to inflammation. Whatever underlying problem is contributing to AFib can also lead to dementia. 

7 signs that your brain is not functioning

  1. Changes in mood or personality – Early signs of cognitive decline include increased anxiousness, irritability, or depression. Individuals in the early stages of dementia are sometimes easily angered or frustrated. Other times they are withdrawn and quiet. Any unexpected changes to personality could indicate the start of brain dysfunction. 
  1. Reduced concentration– Cognitive decline often comes with an inability to focus and decreased concentration. Individuals with cognitive impairment might find it challenging to finish a book or complete a task that requires focus. 
  1. Repetition – Short-term memory loss often causes individuals to repeat questions, phrases, or actions.
  1. Poor judgment – Individuals with cognitive decline sometimes have difficulty making appropriate decisions. Early signs of dementia can include excessive spending, inappropriate clothing choices, or driving mishaps. 
  1. Increased confusion – Mental decline sometimes includes increased confusion. For example, individuals with early-stage dementia may have difficulty remembering what day of the week it is. 
  1. Difficulty with everyday tasks – In the early stages of cognitive decline, individuals may have increasing challenges completing simple tasks, such as grooming, cleaning, and paying bills. 
  1. Challenges finding the right words – While we’ve all had instances where we’ve forgotten what we were about to say, individuals with brain disorders experience more frequent difficulty in finding the right words. 

How do I prevent AFib and dementia?

Many factors can contribute to memory loss and dementia. To prevent cognitive decline caused by arrhythmias, it’s important to examine how to minimize the risks of AFib itself. The following lifestyle can significantly lower your odds of developing both AFib and dementia: 

  • Eat an organic, 100 Year Heart Diet
  • Exercise daily
  • Reduce stress
  • Eliminate alcohol
  • Get time in the sun
  • Rid your home of toxins
  • Get quality sleep 

Next steps

Atrial fibrillation and dementia often go hand in hand. Cardiovascular health is essential to brain health, and vice versa. Unfortunately, a faster heart can lead to a slower mind. To lower your risk of developing brain disorders such as dementia, you may want to see your cardiologist. By ensuring that your heart is in good working order, you can potentially reduce the odds of cognitive decline.

About Dr. Lauren Lattanza NMD, FACC

Dr. Lattanza Office Visit with Patient

As a Naturopathic Physician, I am trained to treat the whole person and get to the root cause of disease.

I went to Arizona State University where I graduated with a bachelor’s degree in psychology with a depth in physiology and minor in Spanish. After my undergraduate degree I was working on prerequisite classes towards medical school, which is when I came to learn that my values identified best with the principles of naturopathic medicine. I knew that I wanted to help patients identify the causes of disease and be able to offer treatments which would improve their health rather than simply treating symptoms.

I dedicated the next 4 years to the Southwest College of Naturopathic Medicine in Tempe, Arizona where I attained my Doctorate of Naturopathic Medicine. I served as Class President all 4 years, Board of Trustees – Student Trustee, spoke as the Club President for our branch of Toastmasters, and was voted by my peers and attending physicians to earn the Outstanding Leadership Award for the Class of 2020. Throughout medical school I took it upon myself to work alongside MDs, DOs, chiropractors, and functional medicine practitioners in addition to naturopathic physicians.

As a Spanish speaking student, I was able to volunteer with community clinics around Phoenix and provide free healthcare to low-income families. Due to this combined exposure, I came to find my passion in treating cardiometabolic and digestive disorders that are all too common, yet largely preventable. I took the opportunity to learn the broad spectrum of healthcare so I can ensure that I am able to provide my patients with the best options.
