You’ll Never Believe the Deadly Connection Between Heart Disease and Dementia
Heart disease and dementia are both common, devastating illnesses that affect hundreds of thousands of adults across the country. Though older adults are more at risk for both these and other health conditions, they can strike anyone of middle age, too.
If that seems overwhelming, there’s good news. Certain healthy habits can decrease your risk of more than one disease at once. If you’re worried about dementia, and your heart, focusing on one might help you avoid the other.
Heart disease is the deadliest illness in the U.S.
It’s the leading cause of death among both men and women in the United States. It kills an estimated 600,000 Americans every single year, and costs the nation billions annually in health care spending and productivity loss.

Dementia is almost just as deadly
Alzheimer’s disease and other types of dementia costed Americans over $250 billion in 2017. Millions of people over 65 live with it, and thousands die from it every year. It’s also a leading cause of death in the U.S., and the only chronic disease on that list without a possible cure.

How does your heart get sick?
There’s more than one type of heart disease — how it impacts you specifically really depends. But narrow or blocked arteries and weakened heart muscle are common reasons your body can’t circulate blood as well as it once did.
There are some risk factors you can’t do anything about, like your age or your genes. Contrary to some myths about the disease, though, it’s not always an immediate death sentence. Neither is dementia.

What causes dementia?
Healthy brains allow people to think, communicate, and remember. Different parts of the brain communicate by sending signals across pathways. A decline in these functions can signal disease.
People with dementia usually have collections of proteins in their brains — some called plaque, and others called tangles. Though doctors don’t know exactly why these develop, they’re likely the reason it’s so hard for these individuals to recall information and communicate effectively.

How heart disease increases dementia risk
Doctors are making new discoveries about how your heart and brain are connected in terms of disease. Whether due to age or other factors — or a combination of things — the more damaged your heart, the more likely you are to experience the progressive cognitive decline often associated with dementia.
Additionally, the same factors that increase your risk of heart disease — like smoking and high blood pressure — also increase your dementia risk.

Easy ways to lower your risk of heart disease
People who don’t sleep well, sit too much, and avoid nutritious foods have an increased risk of heart disease. Even if you don’t smoke, monitor your alcohol consumption, and exercise regularly, these habits still endanger your heart.
Make sure you’re getting enough sleep, taking some steps throughout your day, and balancing your junk food intake with healthier foods to feed your heart the nutrition it needs.

How to lower your dementia risk
Exercise, nutritious food, and cautious drinking aren’t the only habits that can support long-term brain health — though they’re definitely effective.
The more you laugh, the better your chances of preserving brain function as you age. Consistent, high-quality sleep isn’t just good for your heart — it’s good for your head, too. Also, the occasional crossword puzzle wouldn’t hurt.
Next: There’s one diet that could give you the results you want.
This is the best diet for both your heart and your brain
You’ve probably heard that certain foods are good for your brain. The good news is, many of these same foods also boost heart health.
People who follow the Mediterranean diet experience lower rates of heart disease than those who do not. The same diet, rich in plants, fish, and oils, can also decrease your chances of developing dementia. If you want to live longer, consider including more of these foods in your daily eating routines.
