Higher levels of wellbeing may help reduce the risk of memory loss in middle age, suggests new research, which tracked more than 10,000 over 50-year-olds across a 16-year span.

A comparison of genetic data from all over the world specifies many general as well as a population-specific genetic predispositions for the neurogenerative disease Alzheimer’s. The results can lead to more precise and inclusive treatment options / publication in Nature Genetics
