Predisposed to Alzheimers?

There are several conditions that many people suffer from in the middle age that can predispose one to dementia or Alzheimer’s.

Recently, as a practicing plastic surgeon in Florida, I came across an article about some California researchers who found that people who had chronic depression throughout their lives were at an increased risk for dementia/Alzheimer's.  In fact, this chronic depression maybe the early onset of Alzheimer’s.

Also people with more belly fat in middle age have a higher risk of dementia.  Even if your total weight was normal but you had more belly fat your risks went up.

People who smoked in middle age had an increased risk.  People doubled their risk of Alzheimers if they smoked 2 packs/day or more. 

Also people with high cholesterol in middle age increased their risk as well.

I guess good, clean living may have some benefits after all.
