ST. PAUL, Minn - People who smoke are more likely to develop Alzheimer’s disease or dementia than nonsmokers or those who smoked in the past, according to a study published in the September 4, 2007, issue of Neurology®, the medical journal of the American Academy of Neurology.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.
