Omega-3 fatty acids enhance cognitive flexibility in at-risk older adults A study of older adults at risk of late-onset Alzheimer's disease found that those who consumed more omega-3 fatty acids did better than their peers on tests of cognitive flexibility -- the ability to efficiently switch between tasks -- and had a bigger anterior cingulate cortex, a brain region known to contribute to cognitive flexibility

Hospital admissions strongly linked to disability for older adults in last year of life A close association between acute hospitalizations and the development and progression of disability among older adults at the end of life has been found by researchers. Their findings may have profound implications for medical decision-making for older people and those who care for them.

Proteins may slow memory loss in people with Alzheimer's Certain proteins may slow the devastating memory loss caused by Alzheimer’s disease, according to a groundbreaking new study. The researchers found evidence that an elevated presence of a protein called neuronal pentraxin-2 may slow cognitive decline and reduce brain atrophy in people with Alzheimer's disease.

How our gut changes through our lifetimes, and how this determines our overall health Scientists and clinicians have carried out the first detailed study of how our intestinal tract changes as we age, and how this determines our overall health.
