Daily multivitamin may enhance memory in older adults

Memory and thinking skills tend to decline as we get older. Certain lifestyle factors — such as a healthy diet, physical activity, and social interactions — might help to protect cognitive health as we age. Some studies have suggested that taking multivitamins or other dietary supplements may help protect thinking and memory. But few large-scale […]

Study of fruit flies finds hunger causes brain changes that slow aging

Diet affects lifespan but hunger itself also can increase longevity. In Drosophila melanogaster — fruit flies — feeling hungry can increase lifespan because of changes in the brain, according to a new NIA-funded study published in Science. For this study, researchers from the University of Michigan promoted hunger in Drosophila in two different ways. First, they fed […]

High blood glucose accelerates cognitive decline in stroke survivors

High blood glucose levels in stroke survivors are associated with faster cognitive decline, according to an NIA-funded study. In contrast, the researchers found no evidence that post-stroke LDL cholesterol or high blood pressure levels accelerate cognitive decline. These findings, published in JAMA Network Open, suggest that glucose management in stroke survivors may help preserve cognition after […]

Hearing aids slow cognitive decline in people at high risk

As the world population ages, the number of people living with dementia and other types of cognitive impairment continues to rise. Safe and affordable interventions to prevent or slow age-related cognitive decline are greatly needed. Studies have found an association between hearing loss and the development of dementia in older adults. Research also suggests that […]

Sense of smell linked to speed of brain loss and cognitive decline

Having a good sense of smell is associated with slower loss of brain volume and cognitive decline in older adults, and the link between sense of smell and brain and cognitive changes may be especially pronounced among those who develop cognitive impairment or dementia. These are the key findings from NIA-led research published recently in Neurology. […]
