Secondhand smoke and Alzheimer’s disease.

A University of California study has determined that exposure to secondhand smoke can increase the risk of developing dementia. According to Thaddus Haight, study author, ‘…elderly people with high lifetime exposure to secondhand smoke were approximately 30% more likely to develop dementia than those with no lifetime secondhand smoke exposure…’ (Secondhand Smoke Increases Risk of Dementia)

The findings of this study were being presented this week at the 59th Annual Meeting of the American Academy of Neurology held in Boston.
