Determining Your Risk for Alzheimer's and Parkinson's

I just read this the other day so I thought that I would pass it along to all of you.

The key to determining your risk for Alzheimer's and Parkinson's could be in your nose. In a recent study, adults who had trouble identifying the scent of lemons, cinnamon or other similar items were five times more likely to develop Parkinson's disease than those with more sensitive noses.

The researchers believe that the area of the brain responsible for olfactory function may be one of the first affected by Parkinson's. In a separate study, researchers noticed a link between development of brain plaques involved in Alzheimer's disease and a fading sense of smell.

I just thought  that this was an interesting tid bit since I think all of us wonder about these things especially as we get older.
