4 in 10 people may develop dementia after 55–Here’s how you can lower your risk.

As the golden years approach, many of us at The GrayVine start to think more about our health and longevity.
We want to enjoy our retirement, spend quality time with our grandchildren, and maybe even pick up a new hobby or two. But there's a shadow that often looms over these aspirations: the risk of dementia. How can you avoid it?
Recent findings have cast a new light on this concern, suggesting that as many as 4 in 10 people could develop dementia after the age of 55.
The study, published in Nature Medicine, paints a picture of dementia risk that is both more nuanced and more urgent than previously understood.
While the risk of developing dementia increases with age, the study's co-author, Dr. Josef Coresh of NYU Langone Health, emphasizes that the actions we take in midlife can have a significant impact on our brain health later on.
Dementia is a broad term that encompasses various cognitive impairments, with Alzheimer's disease being the most prevalent form.
However, other types, such as vascular dementia, can arise from heart disease or small strokes that affect blood flow to the brain. Often, individuals may experience a combination of factors that contribute to cognitive decline.
The study's findings indicate that the risk of dementia evolves over time. Between the ages of 55 and 75, only 4% of individuals were found to develop dementia.
However, for those who reach 75 in good health, the risk jumps dramatically—20% by age 85 and 42% between ages 85 and 95. This underscores the importance of maintaining a healthy lifestyle throughout our lives.
While some risk factors for dementia, such as age and genetics, are beyond our control, there are daily habits and lifestyle choices that can significantly lower our risk. Here are some key strategies to consider.
1. Protect your heart to protect your brain
What benefits the heart also benefits the brain. Regular exercise, maintaining a healthy weight, and managing blood pressure, diabetes, and cholesterol levels are crucial.
High blood pressure, for instance, can hinder blood flow to the brain, increasing the risk of both vascular dementia and Alzheimer's. Similarly, uncontrolled diabetes can lead to cognitive decline and inflammation in the brain.
2. Stay socially and mentally engaged
Social and cognitive activities can keep your mind sharp. Engage in stimulating conversations, join clubs, solve puzzles, or learn new skills.
If you're experiencing hearing loss, consider using hearing aids to stay connected with others and avoid social isolation, which can contribute to cognitive decline.
3. Safeguard your head
Prevent head injuries by wearing helmets when biking or engaging in other potentially risky activities. Traumatic brain injuries can increase the likelihood of developing dementia later in life.
4. Embrace a brain-healthy diet
Adopt a diet rich in fruits, vegetables, whole grains, and lean proteins. The Mediterranean diet, for example, has been associated with a lower risk of cognitive decline.
5. Get quality sleep
Aim for 7-9 hours of restful sleep each night. Poor sleep patterns have been linked to an increased risk of Alzheimer's disease.
6. Manage stress
Chronic stress can take a toll on your brain. Practice stress-reducing techniques such as mindfulness, meditation, or yoga.
The prospect of dementia is daunting, but the power of prevention is in our hands. By adopting healthier habits and making informed choices, we can significantly reduce our risk of cognitive decline.
