Findings of a new study suggest that women with thyroid hormone deficiency are four times more likely to give birth to children with autism vis-à-vis women who do not have this deficiency.
In order to arrive at this conclusion, researchers at Houston Methodist Neurological Institute and Erasmus Medical Centre analyzed 4,039 Dutch mothers and their children.
Research Methodology These mothers voluntarily registered between 2002 and 2006 for the Generation R Study. Of these 59 mothers were highly T4 deficient, while 136 of them were identified as mildly T4 deficient. In all 80 "probable autistic children" were identified by the study researchers.
For the purpose of the study, a woman having less than 5 percent of normal T4, but producing a normal amount of thyroid stimulating hormone was termed as highly T4 deficient.
The blood samples of the study participants was taken in the 13th week of pregnancy to measure levels of T4 as well as of two other proteins that tend to point towards the cause of iodine deficiency.
T4 Deficiency Leads to Symptoms The study established that in cases where women were severely T4 deficient, the autistic symptoms were more pronounced in children. Likewise, mild deficiency of T4 in mothers resulted in an inconsequential quantum of increase in autistic children's symptoms.
Lack of Iodine in diet is stated to be the most common cause of thyroid hormone deficiency. The findings of the latest study corroborate with earlier findings that suggest foetal brain cells migrate during the process of embryo development.
"It is increasingly apparent to us that autism is caused by environmental factors in most cases, not by genetics. That gives me hope that prevention is possible," said lead author Gustavo Roman, a neurologist and neuroepidemiologist.
The findings of the study suggest that pregnant women should routinely measure their urinary iodine levels as well as thyroid hormone levels.
The study will be published in the journal Annals of Neurology.
Regular doctors want us to cut down on the amount of salt in the diet, but unless pregnant women are eating a lot of fish, they will not get enough iodine/indide.
They’re still not looking at fetal ultrasound eh?
I really wish that, among many other welfare programs, Big Gov medical and scientific subsidies would be eliminated so that we could actually get some real answers to our medical issues.
low thyroid means muscle/joint and lots of fatigue too. Doc lowered mine 3 months ago, muscle/joint and fatigue out the roof where the higher dose had it under control. Beware to get off all vitamins/minerals at least a week before your next test. 1 Iodine tab through the test results off. I get no iodine from food so supplement with 1 tab.
Most companies have gone to sea salt as better for you, this craze has caused a Iodine deficiency in the US. Sea Salt is NOT IODIZED, nor is it white, it is light pink, lt gray or gray. You use less as it is saltier.
Salt was the chosen vehicle for Iodine supplement as it crosses all cultures.
It’s important to note that while a lack of iodine is *a* cause of low T4 levels, it is not the only potential cause.
Drugs that can increase T4 measurements include:
Birth control pills
Estrogen (possibly plant estrogen? chemically similar)
Drugs that can decrease T4 measurements include:
Antithyroid drugs (for example, propylthiouracil and methimazole)
Greater than normal levels of T4 may be due to conditions that involve an overactive thyroid, including:
Germ cell tumors
High levels of the protein that carries T4 in the blood (can occur with pregnancy, use of birth control pills or estrogen, liver disease, and as part of an inherited condition)
Toxic multinodular goiter
Over-treatment with thyroid hormone medicine
Lower than normal levels of T4 may be due to:
Hypothyroidism (including Hashimoto’s disease and several other disorders involving an underactive thyroid)
Malnutrition or fasting
Use of certain medications
And those with high blood pressure are urged not to use salt.
Fukushima has affected the US as well - the information is out there, you just have to look for it.
I would not connect Fukushima with thyroid problems in the US, because radioactive iodine only has a half-life of only 8 days. Here is a map of its spread within Japan.
This puts the limits of its spread to about 200km. The closest point of the US is about 8,800km.
Iodine is about the only element, or isotope, readily uptaken by the thyroid gland. Far more worrisome is the isotope of cesium, which has a half-life of about 30 years, but when consumed goes for the bone marrow.
“An oceanographer at Toyko University of Marine Science and Technology, calculated that the plant is leaking 0.3 terabecquerels (trillion becquerels) of cesium-137 per month and a similar amount of cesium-134. While that number sounds mind-boggling, its actually thousands of times less than the level of radioactive contamination that the plant was spewing in the immediate aftermath of the disaster, estimated to be from 5,000 to 15,000 terabecquerels.
“However, the cesium is retained in the soil under the plant, while strontium and tritium, other radioactive substances, are continuing to escape.”
some would disagree - thyroid problems on are the rise - two in my family alone (Midwest).
The information is not always correctly portrayed.
Interesting research. I hope this goes somewhere: prevention is better than treatment after the fact, and with health care’s costs and organization going the way it has, this kind of knowledge is what’s going to be needed generally.
Like I noted before, there are many reasons for thyroid problems. Doctors routinely test seniors because many experience natural declines in their production of thyroid hormone, which can be easily confused with things like senility.
Even excess iodide may cause hypothyroidism, too little hormone. Autoimmune diseases as well.
“Hypothyroidism is a very common condition. It is estimated that 3% to 5% of the population has some form of hypothyroidism. The condition is more common in women than in men, and its incidence increases with age.”
The possibility of radioactive iodine exposure is quite tiny compared to other causes.
True, when the ENDO lowered my Synthroid from 125 to 112 name brand as I’m allergic to generic, I knew in 4 days I was in hot water. Pain, fatigue plague my body constantly to add to the back pain that doctors caused and won’t fix. Sit still 5 mins and go to sleep, go to bed can’t sleep for the pain, can’t take pain pills Drug induced IBS issuses, bad.
