Ask your competent? doctor EXACTLY HOW MUCH social connections are needed to prevent dementia. I do live jazz two nights a week and a night at trivia, all at bars, so there is alcohol involved. Why does your doctor know nothing specific on how to prevent dementia and how to build cognitive reserve?
Alzheimer’s Risk Linked to Increased Social Activity, Not Isolation
Summary: 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.
While emotional support and loneliness levels remained unchanged, these individuals took part in more social activities. This could reflect early compensatory behavior or increased attention from others noticing subtle cognitive changes.
Key Facts:
- Unexpected Link: Higher genetic Alzheimer’s risk was associated with less reported isolation.
- Positive Engagement: At-risk individuals reported better family relationships and more social participation.
- Cognitive Reserve Role: Social connectedness may help buffer the brain against dementia-related decline.

Many experts believe that social isolation is a risk factor for Alzheimer’s disease.
But a new study, led by UC San Francisco and Boston University, examined the social habits and genetic data of half a million Britons whose average age was 56, and found that the disease may make them more sociable rather than less – at least in the early stages.
What They Discovered
The data from UK Biobank showed that people with a higher genetic risk for Alzheimer’s reported less isolation, participation in a wider range of social activities and happier family relationships.
No differences were found between higher-risk and lower-risk individuals in measuring loneliness, friendship quality and emotional support.
Why It Matters
The study shows that at its earliest stage Alzheimer’s doesn’t make people less socially engaged.
“Their social lives may even expand,” said co-senior author Kotwal.
“We don’t know for sure if they are engaging more with others, or if those around them are noticing subtle changes and giving them more support.”
Need to Know
Social connectedness is believed to delay or reduce the risk of Alzheimer’s by promoting cognitive reserve, the brain’s ability to maintain normal function despite aging or dementia. UCSF research has shown that other non-genetic factors influencing Alzheimer’s are physical inactivity, uncontrolled diabetes and high blood pressure, poor sleep, depression, current smoking and certain medications. Experts believe that 30% of Alzheimer’s may be attributed to these modifiable risks.
