Smoking in middle age doubles risk of Alzheimer's


Recommended Posts

In one of the first studies to examine smoking's effect on the brain, those who smoked more than two packs a day in middle age were 114% more likely than nonsmokers to develop dementia later in life.

Heavy smoking in middle age more than doubles the risk of Alzheimer's disease and other types of dementia later in life, according to one of the first long-term studies to examine the issue.

Smoking has a clear effect on the heart and lungs, but whether it also damages the brain has been controversial. The study, published Monday in the Archives of Internal Medicine, overcomes some of the obstacles that have made it difficult to assess such a link. For example, some previous research suggesting that smoking doesn't cause dementia mostly examined elderly people only for a short period of time.

The possible risks of Alzheimer's I take smoking cigarettes, is more than offset by the alleged benefit and proactive prevention of the same disease I get from smoking tons of dope. :D
