Perry -
I am so glad that this question has been posed by someone doing a study
because I know that environmental factors, such as pollutants and
pesticides are triggers or causative factors in conditions such as PD.

I am convinced that my Dad's PD was caused by factors around his work.
Dad's career was as a Police Officer in New York City.

Dad, 80, was diagnosed with PD about 2 years ago.
Just around that time I did a detailed nutritional assessment of him.
One of the consistent findings is that there is a lot of LEAD in him.
This did not involve physical tests, but series of questions relating
to symptoms.

I was puzzled about the lead, wondering if he could have gotten
lead poisoning from wearing a bullet belt for so many hours a day.
Good guess, but wrong answer.

For awhile, Dad was a motorcycle patrolman.  He also directed traffic
at times.  And of course he and a partner would drive around on street
patrol with the windows open.  This was during the time of leaded
gasoline.  All that time spent in NYC traffic contributed to his breathing
in all the fumes.

Isn't it "interesting" that 1 or 2 of his retired cop buddies also have PD?
I wonder how many other retired ex-cops have PD?

Taking this further, from what I can understand the reason that the
so very crucial dopamine is not being produced is because of an enzyme
malfunction, that the enzyme allowing dopamine production is suppressed.
(Is that right?)  Knowing a little bit about a preponderance of toxic
metals, would it be incorrect to assume that lead has an antagonistic
relationship with this particular enzyme?  And why isn't this studied?
(or is it?)

I have suggested that Dad go for Chelation Therapy or at the very least
take Apple Pectin (which removes lead from the body) but he won't do this.

Instead of virtually a total focus on gene research which could muck up
things in the body we are so ignorant of, I would much rather see more
research done on the thousands of enzymes in our body.  I would much rather
we clean up our environment and our homes, diet and lifestyle than
further messing up our world and our bodies.  I would rather we clean
up the toxins in our bodies than mess around with a mind boggling complicated
genetic structure.

I am convinced that Dad's PD was caused by his continuous exposure to leaded
gasoline over many years and that this toxic lead is inhibiting normal
biochemical processes in his system, on physical and sub-physical levels.
I believe that if this lead were removed --- on all levels --- that his
PD would disappear.

If the sponsors of your study think this is a worthwhile avenue to study,
they may want to begin with retired cops from big cities.  I am sure there
are many organizations of retired cops.  And other professions.

(unrelated to PD but related to toxic metals, dentists have a higher than
average suicide rate:  from all the toxic mercury vapors they have inhaled
over the years which makes them depressed.)

Perry, thank you so very much for exploring this avenue.  I hope my
comments may assist your research.
