Speaking Two Languages May Affect Dementia Risk in an Unexpected Way

A Canadian study links bilingualism with greater cognitive resilience in older adults.

Researchers found bilingualism’s ties to verbal memory and sex hormones were associated with lower odds of dementia-related pathology.

The results suggest dementia risk may reflect a mix of language, memory, and biological factors, not one factor alone.

This could improve how scientists assess brain aging, resilience, and Alzheimer’s risk.
