Smokers Are More Likely To Develop Dementia
People who smoke are more likely to develop Alzheimer's disease or dementia than nonsmokers or those who smoked in the past.
The study followed nearly 7,000 people age 55 and older for an average of seven years. Over that time, 706 of the participants developed dementia. People who were current smokers at the time of the study were 50 percent more likely to develop dementia than people who had never smoked or past smokers.
Smoking could affect the risk of dementia through several mechanisms, according to study author Monique Breteler, MD, PhD, of Erasmus Medical Center in Rotterdam, the Netherlands, and member of the American Academy of Neurology.
