Weakened gut-brain connection may contribute to memory loss Changes to gut bacteria in aging mice hindered communication from the gut to the brain and led to worse performance on memory tasks.

SuperAgers show unique cell signatures in the brain Researchers linked neuron creation to exceptional recall and memory in older adults.

Blood test predicts start of Alzheimer’s disease symptoms Scientists developed an Alzheimer’s “clock” that can roughly predict when symptoms of Alzheimer’s disease will arise.

Lithium levels tied to Alzheimer’s disease and dementia New research suggests that lithium replacement could be a potential approach to prevent and treat mild cognitive impairment and Alzheimer’s disease.

NIH launches landmark project on whole-person health and function Approach involves looking at the whole person—not just separate organs or body systems—and considering multiple factors that promote health.

Measuring aging with brain scans

Measuring aging with brain scans Researchers developed a way to measure how fast a person is aging from a single brain scan.

Daily physical activity, even at light intensities, linked to lower cancer risk NIH study finds number of steps taken daily may be more important for cancer risk than the intensity of activity.
