Alzheimer's Starts Earlier For Heavy Drinkers, Smokers

Heavy drinkers and heavy smokers develop Alzheimer's disease years earlier than people with Alzheimer's who do not drink or smoke heavily, according to new research.

"These results are significant because it's possible that if we can reduce or eliminate heavy smoking and drinking, we could substantially delay the onset of Alzheimer's disease for people and reduce the number of people who have Alzheimer's at any point in time," said study author Ranjan Duara, MD, of the Wien Center for Alzheimer's Disease at Mount Sinai Medical Center in Miami Beach, FL, and Fellow of the American Academy of Neurology.

"It has been projected that a delay in the onset of the disease by five years would lead to a nearly 50-percent reduction in the total number of Alzheimer's cases," said Duara. "In this study, we found that the combination of heavy drinking and heavy smoking reduced the age of onset of Alzheimer's disease by six to seven years, making these two factors among the most important preventable risk factors for Alzheimer's disease."
