Vietnam Veterans with Diagnosed Parkinson’s or Parkinson like symptoms.  

Hi to all,

 

Shelia sent me the following data that is very important to those Vietnam Veterans and families that have been fighting the VA for service-connected disability associated with Parkinson’s and/or Parkinson like neurological symptoms.

 

You will find below a write up by Mayo Clinic that clearly points to a connection in males that were exposed to herbicides, a request for contact data, as well as two Board of Veterans Appeals cases awarding neurological issues associated to Parkinson’s and/or Parkinson like neurological disorders.

 

Now they do not differentiate between the massive amounts of militarized herbicides used with the unprecedented toxic TCDD levels nor the 6 to 25 the normal recommended dose rate that was used in Vietnam from the normal farmer or the rail road worker usage, etc.

 

At this time in our legacy, VA and IOM have both refused to associate military service in the herbicides as a presumptive disorder.  Nevertheless, you will also find references of IOM stating the possibility of a connection.

 

In researching for my book, I also found many references to this neurological disorder as associated to these pesticides and/or herbicides. 

 


 

The Office of Technology Assessment (OTA) was commissioned by congress in 1991 to get a nationwide consensus on toxic chemical damages.  The Department of Veterans Affairs, for the most part, ignored most, if not all of these findings.  It also seems congress did not take the data and “apply it” to those Veterans that said and experienced the same issues as OTA had found and pointed out.

 

The VA's proposal to compensate Vietnam veterans for peripheral neuropathy, as related to exposure to herbicides containing dioxin (Agent Orange), excludes neuropathies under a wide range of conditions.  The proposed compensable neuropathies include only those manifested not later than 10 years following the date of exposure, and excludes those related to the effects of aging, alcohol abuse, trauma, other diseases known to be associated with peripheral neuropathy such as diabetes and Parkinson's disease, and exposure to other toxicants known to produce peripheral neuropathy.  In making such exclusions, however, the VACEH did not take into consideration relevant information on neurological damage.

 
Because of a concern over the wide range of neurotoxic effects being induced in our population by manmade chemicals, the 101st Congress of the United States commissioned the Office of Technology Assessment to prepare a scientific consensus document in 1991 (OTA, 1990).  As explained below, the VACEH basis for excluding peripheral neuropathies under its conditions contradicts the OTA's findings on the biological mechanism of neurotoxic damage such as peripheral neuropathy.


The VA proposed exclusion of peripheral neuropathies that only become evident 10 or more years after service in Vietnam, on the assumption that such a neuropathy could not be associated with Agent Orange exposure, due
to the long interval from exposure.  This assumption contradicts the findings of the OTA, which found that neurological damage is not always detectable clinically, or noticeable by, the sufferer after exposure to a
neurotoxic substance such as dioxin.  As time progresses or old age approaches, the rate of natural neuronal cell death accelerates, and the results of earlier neurological damage may first become evident, or unmasked (OTA, 1990).  The availability of alternate neuronal pathways is reduced, which were formerly responsible for compensating for earlier toxic damage.  The OTA specifically noted the importance of research showing the
possibility that neurotoxic substances were important in Alzheimer's disease, the degenerative brain disease of old age.


The VA also proposed exclusion of peripheral neuropathies which could only be attributed to diseases associated with neurological deficits (diabetes, Parkinson's disease) or alcohol abuse, under the assumption that the disease or alcohol abuse, and not dioxin, was the cause of neuropathy, similarly contradicts the findings of the OTA.  The OTA found that damage to the nervous system from toxicants may first be unmasked by other conditions, such as diseases associated with neurological disorders or the voluntary intake of substances capable of neurological damage (alcohol, prescription drugs). 

 

The OTA cited evidence that toxic chemicals might even be the sole causative agents in some cases of Parkinson's disease, since onset in certain families was at similar ages, and since Parkinson's disease has increased significantly from 1962 to 1984 along with exposures to toxic chemicals.  The OTA also cited evidence that the substantial increase in the incidence of motor neuron disease and amyotrophic lateral sclerosis (Lou Gehrig's disease) between 1962 and 1984 was due to environmental exposures to neurotoxic chemicals.

It is therefore scientifically probable that in the future a higher incidence than normal of peripheral neuropathy will be experienced by Vietnam veterans due to Agent Orange exposure, despite the fact that the peripheral neuropathy was not detected in the 10-year interval after exposure in Vietnam.  The degree or incidence of neurological damage in those Vietnam veterans suffering from diabetes or Parkinson's disease is
also predicted to be higher than others suffering from diabetes or Parkinson's disease, due to earlier aggravating exposures to Agent Orange.


For the same reasons, there is no scientific basis for presuming that alcohol abuse is the only cause of any peripheral neuropathy in a Vietnam veteran.  The Secretary of Veterans' Affairs, therefore, should not place any limitations or exclusions on compensation for peripheral neuropathy, and following the congressional mandate of providing the benefit of the doubt to the Vietnam veteran.  This so-called mandate as we all know is a joke, a sick government joke.


The exclusion of peripheral neuropathy associated with diabetes as a compensable disease is flawed for another reason.  This is because the VACEH conveniently neglected the results of the Ranch Hand study (Roegner, et al., 1991) and other epidemiological research, which shows a dose-related significant association between diabetes and dioxin exposure.  The minutes of the May 23, 1991 VACEH meeting discussed in detail the correlation between serum dioxin in Ranch Hand veterans and increasing diabetic rates, with Dr. Lathrop stating, "these are figures which support an association.”  For the VA to now exclude peripheral neuropathy associated with diabetes, when the VA has not been able to exclude diabetes itself as being caused by dioxin, is spurious.

 

It is important to add here that Secretary Derwinski took the credibility of ‘any scientific conclusions being valid’ to a new low in medical history.  What was a proposed as a 10-year inclusion was reduced to a one (1) year inclusion by Veterans Affairs.  This should mean to anyone in science or the medical field that the Derwinski and the VACEH had no idea of the etiology of what was going on with the association; only mandates to make sure that:

 

A.     Veterans would not be able to qualify to the nonsensical time requirements and the two-year time limit to resolution of the neurological disorder(s).

B.     If Veterans Affairs admitted a CNS>PNS effect causation then the door would be wide open to even more long-term neurological disorders as well as neuro-psychiatric / neuro-psychological disorders.  

 
NEGLECT OF CENTRAL NERVOUS SYSTEM (CNS) EFFECTS


The controlling majority of the VACEH, in making its recommendations to compensate Vietnam veterans for peripheral neuropathy, neglected to evaluate dioxin's central nervous system (CNS) effects. * Because the available evidence for CNS damage by dioxin outweighs that for peripheral nervous system (PNS) among Vietnam veterans, and because of the inseparable relationship between the biological mechanisms by with dioxin exerts both CNS and PNS effects, this failure of the VACEH is indefensible. 

* The CNS consists of the neurological apparatus of the brain and spinal cord (including motor neurons), while the peripheral nervous system (PNS) consists of those nerves in the extremities of the body (arms, legs, etc.).
Peripheral neuropathies are one result of damage to the PNS. 

CNS damage by fat soluble (lipophilic) neurotoxicants such as dioxin has always been found to accompany, and usually precede, any peripheral nervous system (PNS) damage such as peripheral neuropathy. See the discussions of relevant studies in the attached affidavit (Jenkins, 1991).  The prestigious International Agency for Research on Cancer (IARC) concluded as early as 1977 that human CNS damage was associated with dioxin exposures (IARC, 1977a, 1977b).  In 1986 the IARC clearly restated its’ finding that dioxin was associated with both peripheral
neuropathies and personality changes, a neuropsychological consequence of CNS damage (IARC, 1986).


Since the IARC evaluations, many new epidemiological investigations have established an even stronger casual relationship between dioxin and CNS damage, including the Air Force investigations of veterans of Operation Ranch Hand.

 
TOXICOLOGICAL BASIS FOR CNS DAMAGE BY DIOXIN


A discussion of the biological basis for dioxin's neurological is relevant in demonstrating the inseparability of dioxin's effects on both the CNS and PNS.  Neurotoxic substances may exert their effects by several mechanisms
(Anthony and Graham, 1991).  Chemical attack of whole nerve cell structures may result in cell injury or death (neuropathy).  Chemical attack may be specifically on the axon (long nerve fiber) (axonopathy), or the myelin
sheath of the axon (myelinopathy).  Neurotoxicants may also damage or alter the neurotransmitter system, damage the glial cells, which support the primary neurons, or damage the blood vessels supplying the nervous system.

 
The OTA found that degeneration of the axon (axonopathy) is one of the most frequently determined neurological effects from neurotoxic chemicals (OTA, 1990).  If the axon of a nerve cell dies back, it no longer reaches the
next nerve cell, muscle, etc., and cannot transmit any message.  Because the longer axons have more targets (larger surface area) for toxic damage, it is predicted that the longer axons found in CNS are more effected by
neurotoxicants (Anthony and Graham, 1991), assuming the neurotoxicant is sufficiently lipophilic to cross the blood-brain barrier.  A critical difference between nerve cell damage in the CNS compared to the PNS
is that PNS nerve cells can regenerate, while those of the CNS cannot.  Thus, any toxic damage to the CNS is permanent.

 
Although the mechanism by which dioxin exerts its neurotoxic effects, have yet to be fully elucidated, the CNS effects are consistent with destruction of the nerve axons (axonopathy).  Because of the extreme toxicity of dioxin
and the wide range of biological affects, however, the mechanisms of dioxin's neurotoxicity may not be limited to axonopathies.  The hypothesis that dioxin damages the CNS and PNS by destruction of axons is supported by
the similarity of the neurological symptoms caused by dioxin and many other lipophilic neurotoxicants causing both CNS and PNS axonopathies, including carbon disulfide, hexane, methyl n-butyl ketone, trichloroethylene,
polybrominated biphenyls, and polychlorinated biphenyls

(Anthony and Graham, 1991), discusses the enduring CNS deficits found among populations exposed to these other lipophilic neurotoxicants.

 
Lipophilic toxicants such as dioxin are able to cross the blood-brain barrier to affect the CNS. In addition, since the brain is 50 percent lipid (dry weight), compared to 6 to 20 percent lipid in other organs (OTA, 1990), the brain may be particularly vulnerable to accumulating dioxin into its fat content.  Nervous system tissue itself, with its high lipid content, will also act as a selective repository for dioxin.  In addition, the low elimination rate of dioxin from the body will contribute to its ability to reach equilibrium concentrations in lipid-rich nervous system
 

 The mechanism by which dioxin exerts its neurotoxic effects may differ from that of 2,4-D alone (Agent White). The higher polarity of 2,4-D (less lipophilic) compared to dioxin suggests that it would be less capable of penetrating the blood-brain. 

 

Neuropsychological damage may be one of the most significant consequences of exposure to Agent Orange.  The Office of Technology Assessment (OTA, 1990) concluded that neurotoxic chemicals play a significant casual role in development of psychiatric as well as neurological disorders.  Even minor changes in the structure or function of the nervous system were found to have profound consequences for behavioral and other neurological functions.


The OTA found that neurotoxic chemicals can cause or exacerbate anxiety, depression, mania, and psychosis.

 

It is simply amazing how our congress cannot put two and two together and come up with the correct answer even when they paid for the study results.  I guess they figure THEY did the study; what more do you VETERANS want!  Justice and GOVERNMENT ACCOUNTABLY; ----- surly you jest!!!!!

ROCHESTER, Minn.--Mayo Clinic researchers have found that using pesticides for farming or other purposes increases the risk of developing Parkinson's disease for men.  Pesticide exposure did not increase the risk of Parkinson's in women, and no other household or industrial chemicals were significantly linked to the disease in either men or women.


Findings will be published in the June issue of the journal Movement Disorders.

 
"This confirms what has been found in previous studies: that occupational or other exposure to herbicides, insecticides and other pesticides increases risk for Parkinson's," says Jim Maraganore, M.D., Mayo Clinic neurologist and study investigator.  "What we think may be happening is that pesticide use combines with other risk factors in men's environment or genetic makeup, causing them to cross over the threshold into developing the disease.  By contrast, estrogen may protect women from the toxic effects of pesticides."


The investigators identified all those in Olmsted County, Minn., home of Mayo Clinic, who had developed Parkinson's disease between 1976 and 1995.  Each person with Parkinson's disease was matched for comparison to someone similar in age and gender who did not have the disease.  The researchers conducted telephone interviews with 149 of those with Parkinson's and 129 of those who did not have the disease, or a proxy for these people, to assess exposure to chemical products via farming occupation, non-farming occupation or hobbies.  The investigators were unable to determine through these interviews the exact exposure levels of these individuals or the cumulative lifetime exposure to pesticides.

 
Overall, the study found that the men with Parkinson's were 2.4 times more likely to have had exposure to pesticides than those who did not have Parkinson's.  Women who had Parkinson's, on the other hand, had a far lower frequency of exposure to pesticides than men with the disease.


This study was undertaken due to conflicting results from previous studies of pesticides and other chemical products and risk for Parkinson's.


Funding for the study is from two grants from the National Institutes of Health.

 

The medical-records linkage system of the Rochester Epidemiology Project also made this study possible.

The Elderlaw Forum: Calling all Vietnam veterans with Parkinson’s disease!

 
By Professor Michael Myers

Governments lie to their citizens.  It is the norm.  We have come to expect it.  Sometimes we like it that way.  Lies can provide psychological comfort.

 

A senior legal helpline caller has encountered the contradiction of promises versus funding.  He is a 62-year-old Vietnam veteran who served with the United States Marine Corp at the Chu Lai Air Base.  “We were all exposed to Agent Orange during our tour of duty there,” he said.  “I found out in 2000 that I have Parkinson’s disease.  I filed a claim in 2001 and was turned down.”

 

The Veterans Administration ruled “Despite the presumption of in-service herbicide exposure in Vietnam, the Board is not in a position to grant service connection because the veteran’s neurological disorder did not appear within weeks or months of exposure to herbicide agent and resolved within two years of onset.”

 

Mayo Clinic physicians believe the caller’s Parkinson’s is the result of his exposure to Agent Orange while serving in the Republic of Vietnam.  “Mayo researchers have found that using pesticides for farming or other purposes increases the risk of developing Parkinson’s disease for men,” according to the June 2007 issue of Movement Disorders.  Veteran’s law judges in two cases have found an Agent Orange-Parkinson’s connection, but their rulings are not binding on the Board of Veterans’ Appeals.

 

It is unlikely the current administration will add Parkinson’s to the list of Agent Orange residual conditions. A well-executed legal and political strategy is needed.  If you or a person you know has Parkinson’s and served in Vietnam, contact me at 1-605-677-6343, or email at mmyers@usd.edu.

THE ISSUE
 
Entitlement to service connection for a neurological 
disorder, claimed as due to in-service herbicide exposure.  
 
 
REPRESENTATION
 
Appellant represented by:   The American Legion
 
 
WITNESSES AT HEARING ON APPEAL
 
The veteran and his son.
 
 
ATTORNEY FOR THE BOARD
 
L. Cryan, Counsel
 
 
INTRODUCTION
 
The veteran had active service from June 1966 to October 
1969, with approximately four months of additional prior 
service.
 
This matter comes before the Board of Veterans' Appeals 
(Board) from a March 1994 rating decision of the RO, which 
denied the veteran's claim seeking entitlement to service 
connection for a neurological disorder, claimed as peripheral 
neuropathy, due to alleged exposure to Agent Orange while in 
Vietnam.  The veteran submitted a notice of disagreement with 
that rating decision in May 1994.  In July 1994, he was 
provided with a statement of the case.  His substantive 
appeal was received in September 1994.
 
The Board notes that the veteran had previously claimed 
entitlement to service connection for a neurological 
disorder, claimed as Parkinson's disease, due to alleged 
exposure to Agent Orange while in Vietnam, which was denied 
by an October 1988 rating decision.  The veteran submitted a 
notice of disagreement with that rating decision in January 
1989.  In February 1989, he was provided with a statement of 
the case.  His substantive appeal was received in March 1989.  
The matter was received at the Board in October 1989 but was 
referred back to the RO pending review and revision of 
herbicide regulations.  The RO then also deferred a decision 
on the claim pending updated proposed regulations.
 
As noted in a June 1999 remand by the Board, the RO, in the 
currently appealed March 1994 rating decision essentially 
considered both the claimed peripheral neuropathy and the 
claimed Parkinson's disease.  Given that the veteran has 
claimed service connection for a neurological disorder, 
initially claimed as Parkinson's disease and subsequently 
claimed as peripheral neuropathy, and given that the 
veteran's claims were essentially one continuous claim for 
the same neurological disorder, the Board has simply 
characterized the veteran's claim as entitlement to service 
connection for a neurological disorder, claimed as due to 
Agent Orange exposure.  The issue has been so identified on 
the title page hereinabove.
 
The veteran testified at a personal hearing before the 
undersigned Veterans Law Judge, sitting at the RO in 
September 1997.  A transcript of his testimony is associated 
with the claims file.  
 
Finally, it is noted that the case was previously twice 
before the Board and was remanded to the RO in January 1998 
and June 1999 for additional evidentiary development.  
Following compliance with the Board's directives on Remand, 
the case is now returned to the Board for further appellate 
consideration.
 
 
FINDINGS OF FACT
 
1.  The veteran had active military service in the Republic 
of Vietnam during the Vietnam era, and is therefore presumed 
to have been exposed to herbicide agents in service.
 
2.  The veteran has a currently diagnosed neurological 
disorder with Parkinson-like characteristics, also referred 
to as Parkinsonism.
 
3.  The veteran's neurological disorder may not be 
presumptively service connected under the provisions of 38 
C.F.R. § 3.309(e).
 
4.  The competent and probative medical opinions of record 
have determined that the veteran's currently diagnosed 
neurological disorder is at least as likely as not due to in-
service exposure to Agent Orange. 
 
 
CONCLUSION OF LAW
 
With resolution of all doubt in the veteran's favor, the 
veteran's currently diagnosed neurological disorder, referred 
to as Parkinsonism and Parkinson-like syndrome, was incurred 
in service as a result of in-service herbicide exposure in 
Vietnam.  38 U.S.C.A. §§ 1110, 5103, 5103A, 5107 (West 2002); 
38 C.F.R. §§ 3.159, 3.303 3.304 (2004).
 
 
REASONS AND BASES FOR FINDINGS AND CONCLUSION
 
The veteran asserts that service connection is warranted for 
his neurological disorder with symptomatology which mirrors 
that of Parkinson's disease, which he claims is due to in-
service herbicide exposure in the Republic of Vietnam.  
 
I.  Duties to Notify and Assist
 
At the outset, the Board notes that on November 9, 2000, the 
Veterans Claims Assistance Act of 2000 (VCAA) was enacted.  
See 38 U.S.C.A. §§ 5103, 5103A (West 2002).  Among other 
things, the VCAA amended 38 U.S.C.A. § 5103 to clarify VA's 
duty to notify claimants and their representatives of any 
information and evidence that is necessary to substantiate 
the claim for benefits.  The VCAA also created 38 U.S.C.A. § 
5103A, which codifies VA's duty to assist, and essentially 
states that VA will make reasonable efforts to assist a 
claimant in obtaining evidence necessary to substantiate a 
claim.  Implementing regulations for the VCAA were 
subsequently enacted, which were also made effective 
November 9, 2000, for the most part.  See 66 Fed. Reg. 45,620 
(Aug. 29, 2001) (codified at 38 C.F.R. §§ 3.102, 3.159).  The 
intended effect of the implementing regulations was to 
establish clear guidelines consistent with the intent of 
Congress regarding the timing and scope of assistance VA will 
provide to claimants who file a claim for benefits.  See 66 
Fed. Reg. 45,620 (Aug. 29, 2001).  Both the VCAA and the 
implementing regulations are applicable in the present case, 
and will be collectively referred to as "the VCAA."
 
Pertinent to the merits of the veteran's claim of entitlement 
to service connection for a neurological disorder, the Board 
finds that the provisions of the VCAA have been complied 
with.  In light of the complete grant of benefits sought on 
appeal (entitlement to service connection for a neurological 
disorder), no further evidence is necessary to substantiate 
the veteran's claim for service connection.  See 38 U.S.C.A. 
§ 5103(a) (West 2002).  In this veteran's case, there is no 
reasonable possibility that further assistance would aid in 
substantiating the claim for VA compensation benefits.  See 
38 U.S.C.A. § 5103A(a)(1),(2) (West 2002).  Also, further 
notice to the veteran concerning the evidence necessary to 
substantiate his claim or regarding responsibilities in 
obtaining evidence would serve no useful purpose.
 
II.  Factual Background
 
The veteran's service medical records are negative for 
complaints, findings, or diagnosis of a neurological disorder 
of any kind.  
 
A review of the post-service evidentiary record reveals 
numerous medical records clearly indicating that the veteran 
has been diagnosed with a neurological disorder, although 
there has been some degree of variance in the precise nature 
of that diagnosis.  
 
A September 1982 private neurology consultation report 
prepared by Dr. K, indicated that the veteran was 
experiencing progressive weakness of the left side of the 
body and noted that he had a history of having polio of the 
left arm and left leg when he was age 22 months.  There was 
also a history of having served two tours of duty in Vietnam.  
Other numerous subsequent private medical records from the 
neurological offices of Dr. L as well as from a Duke 
University Medical Center doctor indicated that the veteran 
began experiencing left sided numbness in 1982 and there are 
several diagnoses of Parkinsonism shown from 1983.  At one 
time, it was thought that the veteran's neurological symptoms 
could be attributed to basal ganglia disease.  Other doctors 
noted that the veteran may not have a pure form of                      
Parkinsonism, but instead, a Parkinson-plus syndrome such as 
a progressive supranuclear palsy.  
 
The veteran underwent a VA neurological examination in July 
1988, and he gave a history of having been exposed to dioxins 
in service.  The veteran reported symptoms to include 
slowness of movement, muscle stiffness, poor coordination, 
slurred speech, excessive salivation, muscle twitching, 
muscle cramps, tremor, and involuntary movements.  The 
examiner noted that the veteran had many features of 
Parkinson's Disease, but noted that his picture was unusual.  
First, the examiner pointed out that the veteran was young.  
Next, the examiner noted that he could never see the true 
resting tremor, and muscle tone was not significantly 
increased on testing.  On the other hand, he showed a lot of 
the variability of muscle function that one did see in 
Parkinsonism, and he could never convince himself that the 
veteran was functional.  Therefore, the examiner diagnosed a 
neurological problem that was similar to Parkinson's and may 
be a variety of such.  He further stated that he was not 
aware of the veteran's picture being seen with dioxin 
exposure, but would defer that question to those with more 
knowledge in that field.
 
Amongst other medical evidence of record is a July 1990 
letter from Dr. R, a PhD and toxicologist, with the State of 
North Carolina, Department of Environment, Health, and 
Natural Resources, Division of Epidemiology.  Dr. R referred 
to various scientific literature indicating a possible 
relationship between dioxin exposure and various neurological 
disorders, indicating that one cannot rule out the possible 
role of dioxin as a causal agent for various neurological 
disorders, including Parkinson's disease.  Dr. R noted that 
recent scientific literature had brought to light the 
possibility of environmental causes of neurological 
disorders, as opposed to genetic causes, and that this may be 
the reason why more young people were developing that 
disease.
 
Also of record is a report of Dr. R, dated February 1991 and 
titled "[veteran's name] - A Possible Association Between
