What is the reason for the increase of alzheimer's disease?

Lack of awarenss: It's actually recognized more do to better understanding now. It really hasn't increased in incidence.

We live longer: Age is the biggest risk factor for alzheimer's disease so as the number of people who are older increases, the number of people with ad increases. As the stigma associated with the diagnosis decreases, more people are also being diagnosed with it.

Mercury toxicity: There is no single cause of alzheimer's but a growing body of evidence implicates mercury toxicity as a significant cause (see http://www.Medscape.Com/viewarticle/733465). Exposure to mercury has increased over time, primarily from dental amalgam fillings but also from contaminated seafood.Research shows those who got flu vaccine preserved with mercury 5 years in a row had 10x risk of alzheimer's!
