That Annual Flu Shot Might Be Putting Your Brain at Risk

A new study, published by scientists from Bournemouth University in England and in the journal Surgical Neurology International, shows that brain diseases, including dementia and Alzheimer’s, are affecting people at a younger and younger age. This problem has progressed so quickly that the scientists conducting this investigation believe that environmental factors must —  at least in part — be to blame.

The lead scientist believes that this huge increase in such a short time must mean that more than just aging is at work here. The scientists involved in this study compared the rates of brain diseases from 1989 until 2010 in 21 Western countries. This study found that the average age for the onset of dementia was 10 years earlier than it had been in 1989. Also, deaths from neurological diseases, such as Alzheimer’s, had increased significantly for those between the ages of 55 and 74. For those over the age of 75, the death rate almost doubled.

Although these changes were seen in all 21 countries, the country that fared the worst was the U.S.  In the U.S., the death rates from neurological disease in men older than 74 tripled, and for women, the death rate was five-fold. For the first time, more elderly women in America are dying from neurological diseases than from cancer.

Is it possible that Americans’ exposure to mercury from vaccines play a role in the ever-increasing rates of the early onset of neurological diseases like dementia? Although mercury-containing preservatives, such as Thimerosal, were used in almost all childhood vaccines until 2001, mercury is still one of the ingredients used in adult vaccines, such as the pneumonia vaccine. It’s also found in flu shots, which are given to both children and adults.

The Journal of Alzheimer’s disease published a study in 2010 where researchers reviewed 100 clinical and experimental studies that looked into the effects mercury had human and animal cells. In this review of available studies, scientists found that long term exposure to mercury produced many of the same changes in the brain that are seen in Alzheimer’s, including memory problems, cognitive functions, and general confusion.
