“Discovering new ways to delay dementia is crucial with 42 percent of Americans at risk for developing the condition at any time after age 55.” This longitudinal investigation followed participants for decades starting in 1986 to examine the link between vascular problems and dementia. Among participants with all three risk factors, women staved off dementia for longer than men, and white people avoided the disease longer than Black people. “These results suggest that vascular risk reduction may benefit all groups, but that certain populations, such as Black adults, may especially benefit from targeted prevention efforts,” Coresh explained. “Hopefully, these results will encourage people to stop smoking and watch their vascular health closely from age 45 on.”
