Millions of Americans are at risk of developing dementia, but early detection and proactive measures can help delay its onset and mitigate its effects. A new report by the nonprofit research organization RAND reveals that cognitive ability, lifestyle factors, and physical health can predict dementia risk up to two decades before symptoms appear.
The study identified several key risk factors for dementia, including having diabetes, not exercising, and not having worked or having worked a very few years. Addressing barriers such as cost and accessibility could expand routine cognitive testing and connect more people to treatments and resources in the critical early stages of dementia.
Researchers found that addressing lifestyle factors, such as physical activity, social engagement, and cognitive stimulation, can help prevent or slow down cognitive decline. They also identified regional variations in dementia risk, with individuals born in the South facing a significantly higher likelihood of developing dementia, even after accounting for other variables.
While current uptake of cognitive testing among older adults remains low, research suggests that participation would increase if the tests were free, easily accessible, and supported by improved treatment options. Expanding access to affordable cognitive tests could help more people plan for the future and benefit from current and upcoming treatments.
The study’s findings highlight the importance of adopting a lifestyle that supports brain health throughout life. By understanding what increases the risk of dementia, doctors and policymakers can identify people most at risk and provide targeted support to slow down or lessen the impact of cognitive decline.
