Story summary

A study of U.K. Biobank data linked higher genetic risk for Alzheimer’s disease (AD) to lower social isolation and better family relationship satisfaction.
Researchers propose that early changes before AD onset may enhance social connections.
The study included 487,194 participants aged 40 and older, analyzing genetic risk scores from 26 SNPs.
Alzheimer’s, the leading cause of dementia, involves memory loss and cognitive decline.
Up to 45% of dementia risk relates to modifiable lifestyle factors, suggesting that lifestyle changes could improve cognition and reduce risk.
