Alzheimer’s Risk Linked to Increased Social Activity, Not Isolation
by Suzanne Leigh 18/6/25 Neuroscience.News.com
Contrary to popular belief, a new study suggests that people with a higher genetic risk for Alzheimer’s may become more socially engaged—not less. Researchers analyzed data from over 500,000 individuals and found that higher-risk participants reported lower social isolation and more positive family interactions.

Ageing process is unstoppable, finds unprecedented study
by Amelia Hill Jun 2021the Guardian
But an unprecedented study has now confirmed that we probably cannot slow the rate at which we get older because of biological constraints.
The study, by an international collaboration of scientists from 14 countries and including experts from the University of Oxford, set out to test the “invariant rate of ageing” hypothesis, which says that a species has a relatively fixed rate of ageing from adulthood.
Optimism is associated with exceptional longevity in 2 epidemiologic cohorts of men and women
Optimism is a psychological attribute characterized as the general expectation that good things will happen, or the belief that the future will be favorable because one can control important outcomes. Previous studies reported that more optimistic individuals are less likely to suffer from chronic diseases and die prematurely. Our results further suggest that optimism is specifically related to 11 to 15% longer life span, on average, and to greater odds of achieving “exceptional longevity,” that is, living to the age of 85 or beyond. These relations were independent of socioeconomic status, health conditions, depression, social integration, and health behaviors (e.g., smoking, diet, and alcohol use). Overall, findings suggest optimism may be an important psychosocial resource for extending life span in older adults.
