Avoiding These 3 Things in Midlife Is Linked to 13 More Dementia

Key Points:

• A new study published in Neurology Open Access found that middle-aged and older adults (ages 45-65) who maintain normal blood pressure, are diabetes-free, and do not smoke can live about 13 years longer without dementia compared to those with all three risk factors.
• The study analyzed data from over 12,000 participants followed for an average of 26 years, showing that each additional risk factor in midlife is linked to fewer expected years alive and free of dementia.
• While the research shows an association between these risk factors and dementia-free longevity, it does not prove causation and only measured risk factors once at the study's start.
• The World Health Organization's updated guidelines highlight multiple modifiable risk factors for dementia, including managing vascular health, staying mentally and socially active, exercising, maintaining a healthy diet and weight, and reducing alcohol use and air pollution exposure.
• Although some dementia cases cannot be prevented due to age, genetics, and other non-modifiable factors, experts emphasize that healthy behaviors and managing vascular risk factors in midlife can significantly reduce the risk and delay the onset of dementia.
