Scientists don't fully understand what causes some people to get Alzheimer's and others not. Age is the most significant risk factor, but genetics also plays a role. Alzheimer's has no cure, so the focus is on prevention and slowing the disease's progress once the biological changes are detected or when someone has early symptoms. Research has found that paying attention to certain factors may help, no matter a person's age or family history. These include exercise, diet, hearing and vision, blood pressure, and mind-stimulating activities.

A 2023 study suggests regular exercise improves symptoms of depression, anxiety, and psychological distress more effectively than sedentary behavior.

A 2023 study suggests that some brain changes in people with obesity appear similar to those that occur in people with Alzheimer's disease, the most common cause of dementia.

Two studies found that managing stress and eating a plant-based diet with at least seven servings of leafy green vegetables per week can help improve cognitive function and protect against Alzheimer's disease, respectively.

A 2023 study suggests that certain social challenges, such as isolation, may be useful to help predict older adults' risk of earlier death.

Grief can occur from the death of a family member or a friend, from a sudden change in health or lifestyle, or even after a traumatic event like a natural disaster or a mass shooting. No matter the source, grief can cause deep emotional and physical pain. Going through the grieving process is essential for healing. Certain strategies can support people along the way, such as reaching out to the deceased person's social circle, trying talk therapy, and exploring spirituality.

A 2023 study involving more than 29,000 older adults without dementia, followed for 10 years, suggested that people who stuck to at least four healthy lifestyle habits had significantly slower memory decline than people who didn't practice any healthy habits.

A 2022 nationally representative poll indicated that nearly one in five older women reported symptoms of addiction to highly processed foods and drinks over the prior year.

Flavonoids, a class of micronutrients found in most plant foods, have been shown to possibly reduce the risk of dementia by protecting brain cells, improving blood flow, and reducing inflammation. Following a plant-based diet and aiming for at least five to nine servings of fruits and vegetables per day can help people get sufficient amounts of flavonoids.

More physical activity and less time watching TV is best for the body. But how does television time affect risk for declines in memory and problem-solving ability or risk for developing dementia? Researchers have been digging into these questions.
