Diverting dementia

As the population ages, more adults in the United States are living with dementia. Younger family members often are concerned that they too may develop dementia, but the general public is largely unaware that strategies exist to slow or delay onset of dementia. In fact, by implementing a number of healthful strategies throughout their lifespans, patients may be able to reduce the likelihood of developing dementia or at least delay its onset. These strategies include eating a high-quality diet; keeping physically, socially, and intellectually active; preventing or treating hearing loss; avoiding obesity, hypertension, and diabetes; and avoiding or stopping tobacco smoking. This article reviews the recent scientific literature for dementia risk-reduction strategies and offers suggestions to healthcare professionals who wish to help their patients stave off cognitive loss.
