Study Reveals Top Non-genetic Risk Factors for
Alzheimer’s and Parkinson’s, Reports
Boston, MA (PRWEB), July 10, 2012 – The Doctors Health Press, a publisher of
various natural health newsletters, books, and reports, including the popular
online Doctors Health Press e-Bulletin, reports on an on-going study on the top
risk factors of Alzheimer’s.
As reported in Doctors Health Press e-Bulletin
for-alzheimers-revealed), over the past decade, medical professionals and
scientists have been searching for any clues that show links between disease
and environmental toxins. While some diseases are definitely caused by genetic
factors, many others have simply baffled doctors. Alzheimer’s disease and
Parkinson’s disease fall into this category. A lot has been learned about what
happens when someone gets either of these medical conditions, but not a lot is
known about what triggers them and causes them to take hold in the body in the
The Doctors Health Press e-Bulletin article reports scientists generally agree that
there is unlikely a single clear cause of Alzheimer’s. For this reason, many
suggest Alzheimer’s is the result of a combination of inter-related factors,
including genetic factors and environmental influences that could include
anything from previous head trauma to educational level, to experiences early in
life. A new growing body of research is also helping to identify various “lifestyle
factors,” such as dietary habits, high blood pressure, high cholesterol, and
exposure to environmental toxins.
As for Parkinson’s, scientists know that the brain cells that control movement rely
on a chemical called “dopamine.” Dopamine is manufactured in an area of the
brain called the substantia nigra. In Parkinson’s, dopamine-producing cells in the
substantia nigra are lost. In most cases, no one knows why. Some genetic
mutations have been discovered, suggesting that Parkinson’s may run in some
families; however, new clinical trials are suggesting that environment plays a
larger role than inheritance. In fact, the general medical consensus is that genetic
factors are dominant only in Parkinson’s that appears before age 50.
So what’s really happening to usher in these two diseases? For some answers,
consider the results from a recent clinical trial performed by Spanish researchers.
These scientists decided to conduct a review to find which risk factors were most
prominent when it came to Alzheimer’s or Parkinson’s. Here are the results, as
the Doctors Health Press e-Bulletin article, “The Top Risk Factors for Alzheimer’s
Evidence consistently suggests that a higher risk of Parkinson’s is
associated with pesticides.
A higher risk of Alzheimer’s is associated with pesticides, hypertension,
high cholesterol levels in middle age, and high levels of homocysteine,
smoking, traumatic brain injury, and depression.
There is some evidence suggesting that higher risk of Parkinson’s is
associated with high milk consumption in men, high iron intake, chronic
anemia, and traumatic brain injury.
There is also some evidence suggesting a higher risk of Alzheimer’s is
associated with high aluminum intake through drinking water, excessive
exposure to electromagnetic fields from electrical grids, obesity in middle
age, excessive alcohol consumption, and chronic anemia.
