Neuropathy can be a cause of extreme tiredness

An underlying problem affecting a main nerve or affecting many nerves can be a cause of tingling and numbness in the hands or arms and legs. An increased feeling of heaviness of the arms or legs or feeling tired from just holding the arms up in the air may be due to problems with the nerves rather than weakness of the muscles. Autoimmune disease or some nutrient deficiencies (vitamin B12 deficiency most common) can be causes of neuropathy, or nerve damage. Other common causes are mentioned later.

Autoimmune disease itself can be very tiring and a cause of muscle cramps and diffuse chronic pain and it could make it very hard to cope with a physically demanding job. Some types of nerve damage can become permanent but may be reversible if caught early enough and the underlying causes are corrected. Vitamin B12 may be poorly absorbed by elderly people or for others with digestive problems; a monthly injection of B12, bypassing the digestive system, is a common treatment.  Dissolve in the mouth supplements of B12, cobalamin, are also used sucessfully by some people. In Parkinson’s Disease neuropathy has been seen and “perhaps we should be measuring MMA levels in these patients and treating with cobalamin supplementation to reduce MMA levels and prevent neuropathy.” [4]

Recognizing when tiredness is tiredness and when it is due to underlying nerve damage may be a step that can help prevent the nerve damage from becoming more permanent paralysis or numbness. Neuropathy can also affect gland or organ function as well as affecting motion and sensation. Poor coordination can become a problem with walking or with picking up and not dropping things because they just slipped from your fingers. Symptoms may also include feeling moments of burning or stabbing pain and bowel and bladder problems may include constipation or feeling unable to urinate. [1]

Neuropathy may affect approximately 24 million people in the United States. [1]

Neuropathy is more of risk for people with diabetes, about 30% of the cases are associated with diabetes. Heavy alcohol use and traumatic injury can be causes in addition to autoimmune celiac disease, hypothyroidism and other immune system diseases and viral infections sometimes can be a cause. Some types of antibiotics, radiation and chemotherapy treatments may cause neuropathy. Some cases of neuropathy are present at birth. [1]

Since celiac disease may be a cause of neuropathy trying a gluten free diet may be worth trying, (and hypothyroidism can also be a cause of neuropathy and for some people may be due to gluten sensitivity problems). Not overeating sugars and simple starches may help by promoting more stable blood sugar which would be especially important for diabetics but elevated blood sugar may be part of the cause of nerve damage: [3]. Hot pepper – and it’s active ingredient capsaicin may be helpful and warm showers or a bath may also help circulation and muscle relaxation. Taking care with toenail health is important as numbness becomes more extreme minor injuries may become infected and go unnoticed until they are major infections. [1]

Of the 16 million Americans with diabetes, approximately, about 25% have foot problems due to peripheral neuropathy.  Peripheral nerves are those extending out from the brain or spinal cord to the muscles and organs and skin. Neuropathy can progress from feeling tingling sensations of ‘pins and needles’ in the fingertips to not being able to feel sensations of hot, cold or pain. [2]

Peripheral neuropathy has been known to occur with Parkinson’s disease, possibly due to treatment with L-dopa [4], or possibly as a side effect with another commonly used treatment, dopamine hydrochloride. [5] Dopamine producing cells become dysfunctional in Parkinson’s Disease. [6] Dopamine is a brain neurostransmitter involved in movement but it is also has roles in immune system function.

Adequate levels of dopamine are involved in preventing both autoimmune disease and cancer. Research that compared the lifestyles of family members with and without Parkinson’s Disease found that siblings without the disease were more likely to have been coffee drinkers (three or more cups per day) and were more likely to have smoked tobacco cigarettes. Smoking tobacco has negative health risks but it may help boost dopamine levels and may have some protective effects on the dopamine producing cells. [7]

Smoking tobacco my have protective effects for some people but not others. Coffee has also been associated with less risk of developing non-alcoholic fatty liver disease, [8] but again it may be helping those with a certain type of genetics and be a negative risk for people with other types of genes. Obesity and smoking cigarettes once a patient already has non-alcoholic fatty liver disease is associated with the disease progressively getting worse. [9] Fructose, sugar from fruit or refined in the form of high fructose corn syrup, intake has also been associated with worsening of NAFLD. [10]

Protecting liver function may be important for protecting against cancer. The herb milk thistle has been found to have some protective affects for the liver. [12] Cirrhosis of the liver is also associated with peripheral neuropathy so protecting the liver may also help protect the nervous system and brain. [11]

Summary of tips for protecting against neuropathy:

  1. Stable blood sugar and not developing diabetes may help protect the nerves.
  2. Regular exercise and stretching and warm baths or showers and massage and other methods for increasing circulation may help protect the nerves.
  3. Not eating excessively of fructose or simple sugars may help prevent damage caused by glycation of proteins; by helping prevent obesity or diabetes.
  4. Moderate use of coffee may help protect the liver from non-alcoholic fatty liver disease and some types of liver disease have been associated with peripheral neuropathy.
  5. Dopamine or L-dopa when used as a medication to treat Parkinson’s Disease may be involved in development of peripheral neuropathy. Parkinson’s Disease involves dysfunctional production of dopamine so some other issue may be involved that causes peripheral neuropathy or it may be important to have adequate but not excessive levels of dopamine for health of the nerves.
  6. A deficiency of vitamin B12, also called cobalamin, can be non-reversible cause of peripheral neuropathy. [13]
  7. Smoking tobacco may have some protective affects against Parkinson’s Disease for some people but it has also been associated with worsening of non-alcoholic fatty liver disease in patients who already have the disease. It is unclear at this time what genes may be involved in why some people seem less at risk from tobacco smoking than others – overall it has been found to be associated with lung cancer. Chemicals within smoke cause blood vessels to constrict and reduces circulation. It has been associated with worsening of diabetic peripheral neuropathy so quitting smoking may be more protective of nerves. While it may help boost dopamine levels there are many other healthy ways to boost dopamine naturally. [14]
  8. Following a gluten free diet may be helpful in preventing peripheral neuropathy for some people. If hypothyroidism is also a problem then trying a strict gluten free diet may be beneficial as it may be a cause of autoimmune sensitivities. Eating less gluten in that case would still be exposing the body to the autoimmune ‘allergen’ so a trial of a gluten free diet may have to be very strict and last several months to six months before significant health benefits occur (in research on autoimmune celiac disease it took six months on a very strict gluten free diet in order for the levels of autoimmune antibodies against gluten to be reduced — and (potentially) the thyroid hormone which the gluten molecule resembles.

BVO, Brominated vegetable oil is in the same chemical family as PBDE, a flame retardant

*I told you that story to tell you another one — but it is unrelated to autism — so I’m going to get back to part two of the soupcan story later. First a little good news about the food additive brominated vegetable oil — the Coca Cola and Pepsi companies are phasing out use of the flavoring agent in order to have a product line that is consistent across global food markets — the food additive has been prohibited from use as a food additive in Japan, India and the European Union.

BVO is in some citrus soft drinks including Mountain Dew, Squirt, Fresca, and Fanta. It’s also in sports drinks like Powerade and some pre-mixed cocktails.”  It is a food additive that is in the “same chemical family as flame-retardants like polybrominated diphenyl ether (PBDE).” “Early studies suggest that flame-retardant chemicals disrupt normal hormone function, leading to problems with brain development in children, fertility, thyroid function, and possibly cancer.” [http://www.webmd.com/food-recipes/20130129/brominated-vegetable-oil-qa?page=2]

A study in 2012 found that in the U.S. on average we take in more BVO than PBDEs, 4000 times more for adults and 1000 times more for children. BVO was approved for general use in 1958 in the U.S. and then in the 1970s it was modified to approval for use in beverages for an “interim” time period awaiting further research — but we’re still waiting. Use of BVO as a food additive has been banned in Japan, India, and the European Union. In the U.S. it is approved for use in beverages at a level up to 15 parts per million and on average it is added at a level of 8 parts per million. There is some concern that consumers who drink larger portions of the beverages containing BVO on a more frequent basis may be receiving too much of the chemical.    Read More:  [http://www.webmd.com/food-recipes/20130129/brominated-vegetable-oil-qa?page=2]

So how much soda per day might be enough to cause acute bromide toxicity? — Snopes.com (March 16, 2015) write-up on BVO includes two medical reports of bromide toxicity where one patient reported drinking 2 to 4 liters of BVO containing soda per day and the other reported drinking up to 8 liters per day. According to the Snopes report both the PepsiCo and Coca Cola beverage companies have been actively working to phase out use of BVO in all of their beverages. Use of BVO in the Gatorade line of beverages by PepsiCo has already been phased out. The Coca Cola company plans to have the ingredient phased out of all of their beverages by the end of 2015. The companies stand by the safety of the ingredient but also respect the individual consumer’s desire for more natural products and the value of having a product that is consistent across global markets.

Non carbonated fruit flavored beverages also may contain BVO, (citrus flavors more typically). If an adult male can develop bromide toxicity by consuming 2 to 8 liters of a beverage containing BVO per day then a child or toddler, roughly, might get sick by regularly consuming half or a quarter of that amount — or 1/4 liter to 4 liters per day (or approximately 8 ounces to 4 quarts of ‘juice drink’ per day) — however an infant or toddler may be more at risk than adults due to their having less well developed liver function and due to their brains and thyroids still being in developmental stages, so the infant or toddler drinking a BVO containing ‘juice’ drink may be more at risk than adults for having neurotoxin damage or thyroid dysfunction occur. A developing fetus may also be more at risk than adults so avoiding BVO containing beverages during pregnancy and the perinatal time period may help protect the developing infant’s brain and thyroid.

Over the long term any use of brominated products may be adding to the risk of eventually developing hypothyroidism later in life for men, women or children, so while it might be a very good idea to avoid brominated vegetable oil while pregnant or trying to get pregnant, it  might also be a good idea for everyone to avoid it for the sake of their own thyroid’s health. Bromide is chemically very similar to iodine and it may be incorporated into the thyroid hormone instead of iodine in cases of long term iodine deficiency — but the molecule of bromide (or fluoride or chloride) may be making the larger molecule of the thyroid hormone no longer able to function properly — the bromide might be used to produce thyroid hormone that seems like thyroid hormone to a lab test but might not be as functional as a thyroid hormone within the body.

For more information about iodine, and the other halides/halogens: bromide, chloride and fluoride, see Dr. Brownstein’s book:

Autism may be able to be prevented prenatally with individualized perinatal education and nutrition therapy

This got long and complicated and I need to buy a couple of the articles and work on this more but in the meantime, I’m sorry for suggesting the food supply might have something to do with the increased rate of autism or that the health insurance companies don’t want a clear diagnostic procedure etc. but without a lab test that says someone is sick they can save money on paying claims — however costs in the long run may end up being a lot more than they might have been with an earlier diagnosis and preventative treatment. I’m sure the health insurance companies and government and FDA love us all and that autism must be a complete mystery – but leaving something a complete mystery still leaves it a worry for expectant parents and grandparents throughout the pregnancy and even into the early childhood years. The symptoms aren’t usually diagnosed until age two or older. But earlier diagnosis might help prevent more severe loss of function. The condition can cause a sudden or more gradual loss of social skills and development progress.  

Autism can leave a child unable to take care of themselves independently for the rest of their lives. At a rate of 1 child in 45, [Nov. 2015, CDC, http://health.usnews.com/health-news/articles/2015/11/13/cdc-child-autism-rate-now-1-in-45-after-survey-method-changes], there were 3,932,181 births in the USA in 2013, so roughly that would suggest that 87,381 of those children will go on to develop some symptoms of autism or pre-primary developmental delay — and that possibly 87,381 parents will no longer be able to work at their normal jobs because they will be needed as full time caregivers for their child with autism, possibly for the rest of their lives. So if that rate held steady for the decade then in ten years there could be 1,747,620 children with autism and parents who may not be able to work at a normal job. When will it be enough children and parents to do something about?

I closed with the following paragraph but I’m going to paste it here at the beginning too, as the best of the good news: a lab test has been developed that consistently predicted which infants would later go on to develop autism. This helps clear up the mystery of whether autism is a condition that a toddler can suddenly “get” like an infection or have suddenly develop as an acute reaction to something or whether it develops prentally — it develops prenatally and can get worse — which suggests that it might not also have to get worse if appropriate interventions can be provided. Autoimmune disease frequently can flair up, go into remission, flair up again, and go back into remission. Autism appears to be related to autoimmune conditions of the brain so dietary and lifestyle changes might be able to help keep the overactive white blood cells more in ‘remission’ and less busy doing brain damaging things — that would be my hope at least.

A method has been developed using samples of umbilical cord blood to identify which infants are likely to develop autism later in childhood. The method checks fifteen “biomarkers,’ — (various lab values or other physical signs, I haven’t read the full article yet, need to buy it) — infants whose values were more elevated or reduced compared to normal in a certain pattern were found to be predictive of which infants went on to develop autism. [6 ] This is early research but it would help identify which infants were at risk for autistic changes in a year or two, but at birth instead of having to wait — and worry — for a year or two.

I have some good news and some bad news. It looks plausible that autism could be caused prenatally by a combination of low vitamin D (or possibly a vitamin D system that is blocked by pathogens), and low folate availability (possibly due to a genetic methylation defect, [4], defects that may make the supplemental form, folic acid, not as helpful prenatally and possibly even harmful because the folic acid may inhibit the activity of whatever folate is available, [29] ), and increased formaldehyde either from dietary sources like Nutrasweet or from smoking or living in small enclosed rooms with poor ventilation. Other toxins might also be involved that add to an increased risk for there to be production of autoimmune antibodies in the vitamin D deficient mother and fetus. Malfunction in the vitamin D receptor immune functions could lead to malfunctions in the dendritic cell’s ability to inhibit autoimmune overactivity in the immune system. Autoimmune antibodies might cause problems during fetal brain development or later in the child’s life.

Low vitamin D in infants has been associated with autism – but not for all siblings with low vitamin D — so other factors must be involved. And not taking a prenatal vitamin during the three months prior to pregnancy and the first month of pregnancy has been associated with more risk for having a child with autism and certain genetic defects in the methylation cycle that helps make the B vitamin folate more bioactive have been associated with autism risk [4] – but not every mother who doesn’t take prenatal vitamins during the months prior to becoming pregnant has a child with autism — so other factors must be involved.

Not much information is available about Nutrasweet but during digestion the methanol portion of the larger molecule is released which then is broken down into formaldehyde – which is a known cause of birth defects and a known neurotoxin.

Formaldehyde is produced when something is burned so it could be a concern for any people who are around cigarette smoke or inhale other types of smoke regularly. Formaldehyde can also collect in the air in small enclosed spaces, and increased warmth may also increase volatility of the gas so warmer areas or overheated apartments may allow for more accumulation of the gas in poorly ventilated rooms.

Formaldehyde is also found in prepackaged juice products, particularly in older packages, as formaldehyde is produced as the fruit or vegetable juice ages. Formaldehyde is also produced during digestion from the methanol portion of the alternative sweetener Nutrasweet. Studies on the potential risk of the formaldehyde content that might be available to adults from dietary Nutrasweet found that it was a less significant risk than the amount an adult might receive as a cigarette smoker or from environmental exposures. However an adult has a fully mature liver while a fetus does not. Babies and children also have less mature livers and may be more at risk of having chemicals accumulate to toxic levels because they are not being broken down and excreted quickly enough. (Folate, a B vitamin, is necessary to break down formaldehyde, more on that later.)

Formaldehyde can cross the placenta to the fetus where it accumulates to a larger concentration than within the mother’s bloodstream. The fetal liver tissue is less able to detoxify formaldehyde than the mother’s.

Industrial exposure to formaldehyde is associated with an increased risk of the presence of cancer causing human alpha fetoprotein antigens. Occupational exposure to formaldehyde has also been associated with increased levels of alpha fetoprotein in adult male and female subjects. The study subjects with occupational exposure to formaldehyde were also found to have significantly reduced levels of Total Protein, Albumin, and White blood cell count. Subjects with workplace exposure to formaldehyde reported allergic type symptoms including: “sneezing/airways-related symptoms, itching and watery eyes.” [3] Formaldehyde exposure may also be a cause of systemic allergic contact dermatitis, [15, 16] possibly even on the eyelids. [13] A diet designed to avoid formaldehyde intake may be helpful for alleviating the eczema like rash. [14]

Levels of alpha fetoprotein are normally only elevated in pregnant women and the expected infant.

Levels of maternal serum alpha fetoprotein are already being checked regularly as a prenatal screening test because low levels are associated with having a baby with the genetic condition Down’s Syndrome. Levels of maternal serum alpha fetoprotein have been found to be more elevated for the mothers of children with autism than in mothers whose child did not have autism. [1] Alpha fetoprotein (AFP) has immunomodulatory effects and a recombinant human alpha fetoprotein (rhAFP) version has been found to help alleviate autoimmune symptoms in clinical trials that used mice with “experimental autoimmune encephalomyelitis (EAE), the animal model used for the study of MS.” [2] Alpha fetoprotein is normally produced by the fetus and it does cross into the fetal brain where it seems to be involved with controlling estrogen and helping baby girls to be more feminine and less masculine.

/Speculation: So if alpha fetoprotein antigens are involved in causing autism maybe boys are more at risk for the condition because the estrogen connection somehow is protecting baby girls from developing the antigens. However if the basic problem is a malfunctioning dendritic cell system which is making it more difficult for the mother’s body and fetus’ body to accept the presence of each other’s foreign DNA then other proteins might also have antigen/autoimmune antibodies develop. Male infants may simply be more susceptible to autism because their Y chromosome is more foreign to the mother’s body than a female infant’s X chromosomes. / — Someone already figured this part out and explains it better than me, in a Medical Hypotheses journal – if you have the money for the journal article ($31.50, now added to my shopping list). An excerpt from the Abstract: “Prenatal/maternal factors linked to increased autism risk include valproic acid, thalidomide, alcohol, rubella, cytomegalovirus, depression, schizophrenia, obsessive-compulsive disorder, autoimmune disease, stress, allergic reaction, and hypothyroidism. It will be shown how each of these risk factors may initiate expression of genes which are sensitive to retinoic acid and/or estradiol – whether by direct promotion or by reducing production of alpha-fetoprotein. It is thus hypothesized here that autism is not a genetic disorder, but is rather an epigenetic disruption in brain development caused by gestational exposure to chemicals and/or conditions which either inhibit alpha-fetoprotein production or directly promote retinoic acid-sensitive or estradiol-sensitive gene expression. This causation model leads to potential chemical explanations for autistic brain morphology, the distinct symptomology of Asperger’s syndrome, and the differences between high-functioning and low-functioning autism with regard to mental retardation, physical malformation, and sex ratio.” – CR King [29]

So speculatively,

  • if formaldehyde can make it more likely for someone to make alpha fetoprotein antigens,
  • and maternal serum alpha fetoprotein levels are more elevated in the mother’s of children with autism,
  • and low vitamin D is more common in babies who have autism,
  • and vitamin D helps the dendritic cells of the mother and infant accept each other’s foreign DNA instead of making autoimmune antibodies against each other’s foreign proteins,
  • then low vitamin D might leave the dendritic cells unable to prevent autoimmune antibodies from developing
  • which then may cause changes in the developing fetal brain and may leave the child with autoimmune antibodies that may continue to cause changes in the child’s developing brain later in life.
  • The formaldehyde could be from Nutrasweet and bottled juice products and/or from cigarette smoke or other environmental sources or the combined total of all of the sources. The timing of the introduction of aspartame/Nutrasweet to the U.S. food supply in 1981 and the increase in rate of children with autism is very closely correlated. [5] Nutrasweet and Neotame were both inventions of the Monsanto Company and limited research about them is available. Neotame was invented as the patent for Nutrasweet was expiring and Monsanto was able to get FDA approval for it by 2002. The patent for Neotame was sold to a private equity firm, the J.W. Childs Equity Partners II. L.P.. [https://theredpillguide.wordpress.com/2012/02/23/the-red-pill-guide-neotame/]

So in summary the good news is autism may be preventable – but the bad news is that it will be difficult to prove and preventative education and treatment will likely need to be individualized as so many factors are involved.

A summary of the factors that may interact during the prenatal and/or perinatal  (three months prior to conception) time period in a way that may lead to the development of autism within the fetal brain.

Possible Vitamin D Issues – it might not just be a lack of vitamin D or sunshine:

  • Simple vitamin D deficiency
  • An underlying genetic defect in the Vitamin D Binding Protein causes a tendency to become vitamin D deficient more easily than normal. [10, 11, 12] (Might a simple protein deficiency then also add a risk to a simple deficiency of all important proteins?)
  • An underlying infection is present with a pathogen that is suppressing the vitamin D receptor system.

Possible Folate Issues:

  • Simple folate/folic acid deficiency/lack of prenatal vitamin during the perinatal time period. [4]
  • Genetic defect in mother affecting the methylation cycle makes her more susceptible for folate deficiency. [4]
  • Genetic defect in the fetus affecting the methylation cycle makes it more at risk for autism. [4]
  • A methylated form of the vitamin may be more effective for reducing risk of developing autism. The natural food form, folate, is more bioactive than the supplemental form, folic acid, that is used in prenatal vitamins. [29]

Formaldehyde might be accumulating from several sources [3, 5]:

  • Aseptically packaged juices
  • Nutrasweet
  • Neotame
  • Smoking
  • Badly ventilated air.
  • Workplace exposure

Other, other factors that may be involved in development of autism may include a variety of chemicals known to be toxic for brain development and which may be common in our modern environment.  From the Abstract of a review article by Dr. Philippe Grandjean, MD and Philip J. Landrigan, MD, Neurobehavioural effects of developmental toxicity., (The Lancet Neurology, 2014):  “In 2006, we did a systematic review and identified five industrial chemicals as developmental neurotoxicants: lead, methylmercury, polychlorinated biphenyls, arsenic, and toluene. Since 2006, epidemiological studies have documented six additional developmental neurotoxicants—manganese, fluoride, chlorpyrifos, dichlorodiphenyltrichloroethane, tetrachloroethylene, and the polybrominated diphenyl ethers. We postulate that even more neurotoxicants remain undiscovered. To control the pandemic of developmental neurotoxicity, we propose a global prevention strategy.” [30]

And other factors associated with autism that were mentioned in the other hypothesis about autism and folic acid included: “valproic acid, thalidomide, alcohol, rubella, cytomegalovirus, depression, schizophrenia, obsessive-compulsive disorder, autoimmune disease, stress, allergic reaction, and hypothyroidism.”  – CR King [29]

  1. valproic acid, a medication commonly used to prevent seizures in epilepsy, may also be prescribed for bipolar disorder or to prevent migraine headaches. (Valporate (VPA), sodium valproate, and divalproex sodium, Depakote). It has been known to cause serious abnormalities in babies when used by pregnant women and is no longer typically prescribed to women of childbearing years. [Wikipedia]
  2. thalidomide,a medication that was prescribed to pregnant women for preventing nausea in the 1960s but it was discovered to cause serious birth defects. It is still used for the treatment of leprosy and still has been known to cause birth defects in the babies of women with leprosy who become pregnant. [http://toxsci.oxfordjournals.org/content/122/1/1.full]
  3. alcohol, – alcohol use by the mother during pregnancy or by the father during the days prior to conception can be a cause of Fetal Alcohol Syndrome in the infant. A zinc deficiency in the pregnant woman may increase the risk of the expected infant developing FAS. [search term alcohol FAS zinc deficiency]
  4. rubella, – also known as German measles, it is the R part of the MMR vaccine. It is rare in the U.S. now with less than ten cases per year but can cause defects in an expected infant if a pregnant woman gets sick with the infection prior to 20 weeks gestation. [http://www.whattoexpect.com/pregnancy/pregnancy-health/complications/rubella.aspx]
  5. cytomegalovirus, a viral disease that may affect vitamin D levels: “However, when outliers were removed, the association was not apparent. The effect of outliers could not be assessed when vitamin D was dichotomized because no patients with CMV antibodies had sufficient vitamin D levels after outliers were dropped.” [http://www.ncbi.nlm.nih.gov/pmc/articles/PMC3134182/]
  6. depression, – can be a symptom of hypothyroidism and has been associated with vitamin D deficiency [webmd.com/depression/news/20120627/vitamin-d-deficiency-linked-to-depression] and with folate deficiency. And the methylated form was given as a supplemental treatment, L-Methylfolate, rather than the unmethylated form, folic acid, which is the form used in prenatal vitamins.   [psychologytoday.com/blog/the-integrationist/201310/depression-wont-go-away-folate-could-be-the-answer] Depressive disorders have been associated with impaired methylation: [http://www.ncbi.nlm.nih.gov/pubmed/16194269] And with zinc deficiency: [https://www.psychologytoday.com/blog/evolutionary-psychiatry/201309/zinc-antidepressant]
  7. schizophrenia, vitamin D deficiency is more common in people diagnosed with schizophrenia. [http://psychcentral.com/news/2014/07/23/vitamin-d-deficiency-common-in-schizophrenia/72813.html] And folate and B12 have both been found to help treat schizophrenia symptoms (or help treat those patient’s whose symptoms are actually due to an underlying deficiency of folate or B12 which may cause symptoms that resemble schizophrenia and providing the nutrients simply is helping the brain to function normally again.) [http://www.naturalnews.com/039453_vitamin_B12_folate_schizophrenia.html] And a zinc deficiency/copper excess is more common in schizophrenia: [http://www.academia.edu/1096257/The_Role_of_Zinc_Supplementation_in_the_Treatment_of_Schizophrenia] And a zinc deficiency prenatally may be involved in the causing schizophrenia later in life: [http://www.ncbi.nlm.nih.gov/pubmed/1491625] [http://www.bmj.com/rapid-response/2011/10/30/does-zinc-deficiency-early-foetal-life-cause-schizophrenia]
  8. obsessive-compulsive disorder, – can be early symptoms of a B12 deficiency. [http://www.ncbi.nlm.nih.gov/pmc/articles/PMC3271502/] Has been associated with folate deficiency, elevated homocysteine levels and impaired methylation function: [http://www.ncbi.nlm.nih.gov/pubmed/16194269]
  9. autoimmune disease, – associated with vitamin D deficiency and malfunction of the dendritic cells ability to promote self tolerance of the immune system. The dry cleaning chemical and degreaser tetrachloroethylene has been shown to cause autoimmune disease in lab animal studies on toxicity: [http://www.atsdr.cdc.gov/sites/lejeune/tce_pce.html]
  10. stress, – increases cortisol and inflammatory stress chemicals, a lack of antioxidant nutrients may make it more difficult for the body to recover from the stress response. [http://www.ncbi.nlm.nih.gov/pmc/articles/PMC1876613/] And may use up stores of folate and cause elevated levels of homocysteine. [http://www.nejm.org/doi/full/10.1056/NEJMc066569] Elevated levels of cortisol during pregnancy has been shown to cause reduced growth rate in the babies in animal studies. [https://en.wikipedia.org/wiki/Cortisol]
  11. allergic reaction, and the vitamin D receptor and the Dendritic cells are what control the immune system’s allergic reaction. Excerpt: “1α,25-dihydroxyvitamin D(3) (calcitriol), the biologically active form of vitamin D, is an immunomodulatory hormone, e.g. it inhibits IgE synthesis in B cells.

  12. hypothyroidism. – may be associated with iodine deficiency which prenatally can cause mental retardation and thyroid defects in the expected infant. Hypothyroidism in female workers has been associated with the flame retardant, polybrominated diphenyl ethers,  [http://www.ncbi.nlm.nih.gov/pubmed/26606679], and the insecticide chlorpyrifos,  [http://www.iss.it/binary/inte/cont/CPF_ENG.pdf], and the pesticide known as DDT dichlorodiphenyltrichloroethane also  [https://preventdisease.com/news/10/022510_pesticide_exposure_underactive_thyroid.shtml], [http://www.ncbi.nlm.nih.gov/pubmed/24064777], and polychlorinated biphenyls [https://www.researchgate.net/publication/26873383_Hypothyroidism_Induced_by_Polychlorinated_Biphenyls_and_Up-Regulation_of_Transthyretinand fluoride are also associated with risk of hypothyroidism.

To help prevent autism from occurring prenatally we may need to work together to show that a combination of nutritional deficiencies or metabolic defects and environmental toxins may be causing autism to develop in infants prenatally. And we may need to work together as a group of concerned individuals rather than waiting for the government or a medical corporation to look further into a problem that might leave them at some risk of legal repercussions. Historically there have been several examples of government and corporate interests blocking the lawsuits of factory workers or townspeople whose health was damaged by industrial chemicals. The lawyers were able to show expert testimony demonstrating that the supposedly ‘harmful’ toxin really had some beneficial use and was really a safe and helpful ‘treatment.’ If we could make this about helping the babies stay healthier and more on track developmentally then insurance companies and governments would probably save a lot of money in the long run actually.

Pretending things are a mystery makes it harder to work on solving the underlying problems and preventing more cases from developing into future years or future decades. Thalidomide was a mystery that got solved. Only a few pregnant women with leprosy have to worry about whether their baby might be born with thalidomide birth defects. Before the cause was known every pregnant woman of that generation probably was scared. Now we do have a variety of information about autism and putting together the puzzle is a little complicated but the good news is that it is not a complete mystery and may be preventable with individualized health guidance that begins at least one to three months prior to conception – the prenatal vitamin research suggests that the pre-conception diet is important.

Fetal Alcohol Syndrome has been shown to be related to the father’s alcohol intake around the time of conception as well as the mother’s alcohol intake during the pregnancy so the father’s diet on the days before conception may also be involved in autism development — zinc is very important for male fertility. A longevity type study could include information about both the mother and the father’s health prior to conception and then follow the pregnancy and infancy and hopefully the preventative diet and lifestyle changes would have prevented autism from occurring. 

Part of the bad news that didn’t make it into the earlier discussion of the digestion of menthol and formaldehyde is that humans have a genetic defect that makes menthol extremely more toxic to us than to all other animals — so lab research would demonstrate that menthol isn’t really that bad after all –(to lab animals, that is, but let’s keep that part a secret between corporate research scientist’s and their consciences). So in a global corporate NAFTA/TPP type world where a corporation can sue nations over lost profits, feasibly corporate research scientists and lawyers could force nations to either accept the products made with aspartame and Neotame whether it is a risk to their citizen’s health or not, or else pay the corporation for their estimated lost profits.

Aspartame and Neotame are so much sweeter than sugar that they are simply cheaper to use in food products than sugar, and since its introduction in 2002 Neotame has never even had to be listed with the ingredients, so sweet, delicious, calorie free and guilt free, no alternative sweetener was used in that product according to the label. Aspartame is the number one food additive for consumer complaints to the FDA about adverse side effects. With Neotame not ever being listed on the food label consumers have no idea if they consumed it or not even if they do have an adverse effect and we have no idea if the FDA would have received consumer complaints about the food additive because it was never required to be added to the ingredient label. People who avoid aspartame due to it causing migraines can’t look for Neotame on the ingredient list.

Avoiding all processed foods and all restaurant meals seems like a lot to ask of pregnant women but that might be necessary in order to avoid Neotame. And with Neotame as a possible source of formaldehyde for the developing fetus then as a prenatal nutrition counselor that would be the most cautious advice given the research that is already known about menthol and formaldehyde’s risks to fetal development. Avoiding all toxins and reducing stress and risk of infection would be the ideal goal for all pregnant women.

Working towards removing aspartame/Nutrasweet and Neotame from the food supply may be an impossible goal given the deep pockets of corporations but trying to get Neotame added to the ingredient list seems like a necessary compromise or first step if we are really going to be able to help prenatal and perinatal women avoid all sources of formaldehyde in the hopes of helping prevent autism from developing in the child later in life.

*This got long and complicated and there’s more: The other, other factors would include undiagnosed cases of hypothyroidism and undiagnosed iodine deficiency and BPA/pthalate exposure. Each individual mother/child with autism probably have a slightly different combination of genetic and nutritional susceptibilities and negative load of various environmental toxins and maybe even a sensitivity to the supplemental folic acid (supposedly helping prevent spina bifida but may be adding to autism risk for the babies of moms who have certain genetic defects in the methylation cycle).

So this is a preliminary draft of a preventative health education strategy for trying to prevent autism. A longevity study that started with women at least three months prior to conception and followed them and their children for years would be able to try a multi-factored prevention plan and wait and see if fewer of the children developed autism than compared to the rate of children developing autism in the average population. [rate at 1 in 45 births, Nov. 2015, CDC, http://health.usnews.com/health-news/articles/2015/11/13/cdc-child-autism-rate-now-1-in-45-after-survey-method-changes] Imprecise diagnostic criteria makes it easier for insurance companies to deny coverage.

A method has been developed using samples of umbilical cord blood to identify which infants are likely to develop autism later in childhood. The method checks fifteen “biomarkers,’ — various lab values — infants whose values were more elevated or reduced compared to normal in a certain pattern were found to be predictive of which infants went on to develop autism. [6 ] This is early research but it would help identify which infants were at risk for autistic changes in a year or two, but at birth instead of having to wait — and worry — for a year or two.

One billion IQ points and iodine

Preventing iodine deficiency can help improve the quality of life for women and their families by increasing intelligence in addition to helping general health and possibly helping to reduce risk of some types of cancer. [Cancer and iodine] Iodized salt and use of iodine supplements for young women of child bearing age are two solutions discussed in the book Half the Sky: Turning Oppression into Opportunity for Women Worldwide (2009). Severe iodine deficiency prenatally can cause mental retardation in the infant but moderate iodine deficiency has been found to reduce intelligence by an ten to fifteen IQ points. Improving access to iodized salt and iodine supplements for women around the world could add to the intelligence of the next generation of our world’s supply of inventors and business builders.

“Worldwide, iodine deficiency alone reduces humanity’s collective IQ by more than 1 billion points. According to one estimate, just $19 million would pay for salt iodization in poor countries that need it.”

– Half the Sky, (2009), p 172.

The volunteer organizations Kiwani’s International and UNICEF have helped provide iodine fortification around the world. [1] Salt iodization has met with community resistance in some areas possibly due to negative rumors that became associated with the programs. [2, 3]

Iodine deficiency can be common problem for people in developed nations too. Prenatal nutrition is important for everyone.

A study on the iodine levels of prenatal women in Australia found mild deficiency to be a problem for many of the women, “48.4% of the Caucasian women, 38.4% of the Vietnamese women and 40.8% of the Indian/Sri Lankan (ISL) women.” Follow-up research examining possible dietary differences between the groups was recommended in the article abstract. [4] Seafood and seaweed can be naturally good sources of iodine.

Talking about IQ as group averages may bother some people. A different way to consider it as individual infants. Mild iodine deficiency prenatally might leave the infant who had a potential of 115 IQ with 100-105; the infant with a potential of 100 with 85-90; the infant with a potential of 80 with 65-70; and the infant with a potential of 140 with 125-130.

Improving prenatal nutrition is good for each individual’s potential and their potential intelligence boost might not just be in IQ but also might include an improvement in social skills and emotional skills, maybe even physical skills. We don’t have national and international testing in place for assessing social and emotional skills, so we don’t know what we don’t know, do we? Good thing we can find out —-> more research is needed about the possible other benefits but there is no question about the benefits of preventing mild or severe iodine deficiency during pregnancy with increased cognitive skills on average.

Research comparing the iodine levels of women between their own pregnancies and then following the differences in IQ between siblings might be another way to show a connection between iodine deficiency prenatally and cognitive skills.* A difference has been found between sibling’s IQ in a large study (n=241,310), first born children scored about 3% higher than second born and 4% higher than third born. The difference was an average and was not observed in every family. [5] Iodine levels were not mentioned. Congenital hypothyroidism is more common for infants of multiple pregnancies, such as twins and triplets and for infants born to older women than younger:

In addition, New York found the incidence nearly double in twin births (1:876) as compared to singletons (1:1765), and even higher with multiple births (1:575). Older mothers (> 39 years) had a higher incidence (1:1,328) compared to younger mothers (< 20 years, 1:1,703). [6]

*A research study that provided extra iodine supplementation for mothers expecting twins or multiples and older mothers and then tracked iodine levels for the mothers and IQ levels for the children might be more ethical based on the known risks of congenital hypothyroidism and the benefits of improved IQ on average then the idea to track a woman’s iodine levels over progressive pregnancies and then measure the IQs of the siblings. It would be more ethical to provide iodine supplementation if levels were found deficient and later see if the siblings IQ levels were statistically similar.

Women all over the world in all economic brackets may not be getting as much iodine as their bodies need. The thyroid is well known as needing iodine and it has priority within the body for uptake of the mineral but the ovaries [7] and the mammary glands [8] need iodine too. Iodine is important in endocrine glands throughout the body in men as well as women.

Getting everyone off to a good start prenatally is just a good start to the rest of the life. Iodine intake is important at all stages of the lifespan.
