Study links smell sensitivity to genetic regions, potentially aiding early Alzheimer's detection.
A large genetic study involving over 21,000 people found that ten genetic regions, seven of which were newly discovered, affect how we perceive everyday smells like clove and cinnamon.
The study also revealed a link between smell sensitivity and the risk of Alzheimer's disease, suggesting that smell tests could help detect early neurological issues.
Three genetic regions showed different effects in men and women, highlighting gender-specific differences in smell sensitivity.
