Science Behind the Book

200 Scientific Studies – Author’s Note About Scientific Sources

In writing “100 Simple Things You Can Do To Prevent Alzheimer’s and Age-Related Memory Loss,” I did extensive online searches of the medical literature on Pub Med, the world’s largest compendium of scientific journal articles, operated by the National Institutes of Health. I also searched the websites of  individual medical journals, academic research centers, government agencies, medical professional associations, major newspapers, magazines and specialized blogs  on the brain, neurology, geriatrics and Alzheimer’s. I attended online Webinars and video conferences on the latest scientific investigations into the initiation, progression, diagnosis, and  epidemiology of Alzheimer’s and on promising interventions to delay, stop or even reverse its  pathology and symptoms.

 I interviewed numerous leading Alzheimer’s researchers about their findings by phone and email.  I also consulted many books on Alzheimer’s and related topics.  

The number of studies I have read and relied on for a basic understanding and advice over the ten years or so I have been collecting information on the possibilities of preventing Alzheimer’s are in the thousands. They have provided much background and perspective on Alzheimer’s research.   It is impossible to list all of them.     

However,  here are more than 200 key scientific references that support the information in  “100 Simple Things You Can Do To Prevent Alzheimer’s…” Using these references, anyone can look up the abstracts and the articles by going to and putting in the name of the researcher,  subject matter or article title. All abstracts, summarizing the conclusions, are free, as are some full articles. Other full articles require a fee for downloading.
