The Mediterranean diet is associated with a variety of health benefits, including a lower incidence of dementia. Now, researchers have identified a specific ingredient that protects against cognitive decline: extra-virgin olive oil. In a new study, the researchers show that consumption of extra-virgin olive oil protects memory and learning ability and reduces the formation of amyloid-beta plaques and neurofibrillary tangles in the brain -- classic markers of Alzheimer's disease.

Slowing down the aging process might be possible one day with supplements derived from gut bacteria.

Sleep loss in mice sends the brain’s immune cells into overdrive. This might be helpful in the short term, but could increase the risk of dementia in the long run

A new study finds wine-derived human gut metabolites may have neuroprotective capabilities.Low to moderate intake of red wine can delay the onset of neurodegenerative diseases such as Alzheimer's and Parkinson's. Researchers have now found out how wine compounds are protective against neuronal death: they should pass through your stomach first.

Using human skin cells, University of California, Irvine neurobiologists and their colleagues have created a method to generate one of the principle cell types of the brain called microglia, which play a key role in preserving the function of neural networks and responding to injury and disease.

A team of neuroscientists at the University of Pennsylvania has shown for the first time that electrical stimulation delivered when memory is predicted to fail can improve memory function in the human brain. That same stimulation generally becomes disruptive when electrical pulses arrive during periods of effective memory function.

Strawberry extract can inhibit the spread of laboratory-grown breast cancer cells, even when they are inoculated in female mice to induce tumors, new research shows. However, the scientists do point out that these results from animal testing can not be extrapolated to humans.

Being able to sleep well in old age can cut the risk of developing a wide range of mental and physical disorders such as Alzheimer’s disease, say scientists.

A gold-standard clinical trial provides evidence that diet, exercise and an active social life can help prevent cognitive decline.
