Blood Test for Alzheimer's?
I subscribe to the Amen Clinic's E-Newsletter (has nothing to do with religion) and everything to do with brain, behavior, health.
Check out Amen Clinics for some great information and note there are more pictures on the site of all different kinds of brains on alcohol; brains on drugs, brains on coffee and cigarettes. All very interesting as well as informative and rather scary. How far we've come in researching the human body.
