Despite what this article says, smokers are at no risk of getting Alzheimer's.
If you read posts in smokers' groups before, as well as reading info on Smokers Club Inc, you might have come across research that shows smoking prevents Alzheimers.
But I do have a comment on a quote from this cited article.
"Researchers announced these results after analyzing seven years of data from almost 7,000 people over age 55."
First of all, there are a LOT more than 7,000 smokers over the age of 55. So this is like a small sample to study. And second, this research should've extended for like 30 years at most. Because smoking has been around for decades and really centuries. Not just for the past 7 years.
So I'm gonna get Alzheimer's based on a study that dates back to 7 years, and I have a 50 percent chance of getting dementia, which is another term for Alzheimer's? What were the chances of a smoker getting Alzheimer's say 45 years ago?
I'm taking this "study" as a grain of salt. It's no different from me reading I have a greater chance of getting diabetic or getting STDs for simply being an African-American. ANYONE can get one of these two risks I mentioned. Not just me and fellow bros/sistas.
I heard of folks coming down with Alzheimer's AFTER they quit smoking. My grandpa was one of them. (He's smoking his Camels in heaven now.) But I never heard of a SINGLE smoker getting Alzheimer's without quitting the habit.
My advice for smokers: If you don't want to get Alzheimer's, keep on smoking!
