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

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.

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

Dementia Research 2017: Caffeine Is Among 24 Compounds That May Prevent Dementia, Study Says

As we age, some systems in the body don’t work as well. Eyesight weakens, there can be some minor age related memory loss and many people move a little slower and don’t stay as active. Sleep disturbances are common as well, but recent research shows that sleeping patterns could be an indicator of another problem seen in the elderly: dementia. Currently estimates put the number of people dealing with some form of dementia at about 46 million globally. In the United States, there are approxima...

The risk of dementia is slightly higher in people with minimal exposure to benzodiazepines but not with the highest level of exposure. These results do not support a causal association between benzodiazepine use and dementia.
