Promoting Healthy Aging to Reduce the Risk of Dementia: A Public Health Imperative.

Alzheimer's disease and related dementias place an enormous burden on individuals, families, health and long-term care systems, and governmental budgets. As the burden escalates with rising prevalence, attention has increasingly focused on how the risk of developing dementia can be reduced. Evidence indicates there are ways, from a population perspective, to reduce the risk of cognitive decline and possibly dementia, including through healthier lifestyles. It is imperative that the public health community lead the effort to address modifiable risk factors and social determinants of health for dementia and promote healthy aging through public health action.
