Overview Autism and vitamin D

Did you know?
  • Autism has seen huge increases around the world in the past few decades
  • There are many proposed reasons for the increase; including
      low Vitamin D, antibiotics, and Roundup
  • There are 27 reasons to associate Autism with low vitamin D
  • Children of women who had higher levels of vitamin D have lower risk of autism

  • FACT: Studies have shown an association of autism with many factors
  • FACT: Clinical trials are underway testing if supplementing with vitamin D will decrease autism
  • UNCERTAIN: Vitamin D help prevent autism before and after birth
  • OPINION: Vitamin D will be proved to both PREVENT and TREAT Autism
  • RECOMMENDATION: Take extra vitamin D when pregnant
    !There is a tiny risk in taking vitamin D, but a major risk in not doing so if you already have an autistic child

CDC update: 1 in 88 as of 2008 Reported March 2012
This is a 78 % increase in (2003-2008) for ALL children
110% increase for Hispanics, and 91% increase for black children (2003-2008) (dark skin strongly points to vitamin D)

An increase of about 30% from 2008 to 2010, which is also an 120% increase in decade since 2000/2002

Autism prevalence


Recent Autism items by Dr. Cannell of the Vitamin D Council

  1. Both have strong inheritance features – Vitamin D about 60%
  2. Both have gotten substantially worse in last 30 years
  3. Vitamin D is known to be involved in brain development
  4. All autistic children are vitamin D deficient, but not all children who are deficient are autistic: since genes are involved as well
  5. When giving vitamin D to cure children of rickets “mental dullness” decreases as well
  6. Children with genes which give them too much (Williams Syndrome) have to reverse of autism – too sociable
  7. Mothers having lots of fish (and thus more vitamin D) give birth to kids with less autistic symptoms
  8. Both associated with weak bones
  9. Both worse around the age of weaning
  10. Autism is more common in rich families – more likely to apply sun screen and stay indoors
  11. Autism increases with drugs which lower levels of vitamin D
  12. Seizures are common with Autism - Vitamin D has been shown to reduce seizures
  13. Fewer autistic symptoms (such as sleep problems) during summer: when child gets more vitamin D from the sun
  14. Both worse with latitude
  15. Both vary with Ultraviolet light
  16. Both vary with time of year (more birth of autistics in March in Northern hemisphere)
  17. 2X more urban autism – less UVB in urban environments
  18. Both worse with pollution
  19. Both worse with increased clouds and rain
  20. Both worse with closely spaced pregnancies
  21. Autistics have abnormal immune response – similar to that of vitamin D deficiency
  22. Low levels of vitamin D in mother animals reduces brain function in offspring
  23. Vitamin deficient rat pups have similar brain abnormalities to that of human autistic children
  24. Autistic children get less vitamin D in their blood for the same amount of sun exposure
  25. The 4 males/1 female autism ratio can be explain by the observation that estrogen increases vitamin D in the brain (testosterone does not)
  26. Both worse in African Americans (A-A 2-3 increased autism rate)
  27. Both worse in Dark-skinned immigrants in Europe

Is Autism a Vitamin D-Deficiency Disorder?

by Marc Sorenson EdD (PhD in Education) http://www.vitaminddoc.com/d3autism.html

As I have pointed out in my book, both children and adults with autism typically show difficulties in verbal and non-verbal communication, social interactions, and leisure or play activities.1
The cost of autism is about $35 billion annually, and the societal cost for each case is about $3.2 million.2
The most alarming increase in autism is observed over the past few decades, and its incidence is currently growing at the rate of 10-17% per year.39
Dr. John Cannell wrote a compelling paper on how autism could be caused, at least in part, by lack of vitamin D during brain development.[3]
Much of this post discusses his primary arguments.
Cannell points out that in 1989, about the time autism began its most rapid increase in incidence, the American Medical Association Council on Scientific Affairs first warned of the perceived dangers of sun exposure and advised keeping infants out of the sun as much as possible.[4]
In 1999, when autism risk began to really skyrocket, the American Academy of Pediatrics advised to keep infants out of direct sunlight and to make sure activities minimized sun exposure.[5]
In 2002 the Centers for Disease Control reported that the efforts had been quite successful.5 It is quite possible that the result of all of this "protection" has been an increase in autism, since the increase in the incidence of autism has closely paralleled the increase in "sunscare efforts."
Vitamin D is absolutely essential for brain development[6] [7] and that children are deficient because of sun "protection" measures that lower vitamin D levels.
My opinion is that this is the major reason for the surge in the rate of autism. Here are more of Dr. Cannell's autism/vitamin D-deficiency links:
Both autism and vitamin D deficiency are associated with abnormally high inflammation.[8] [9]
Low consumption of vitamin D-rich seafood in pregnant women correlates to increased risk of their children's low verbal IQ's, poorer social performance, communication and motor skills.[10] [11]
Dark-skinned people are far more likely to be vitamin D deficient because they require more sun exposure to produce it.
If the theory is correct, the rate of autism among black children would be higher than that among white children due to maternal vitamin D deficiency and fetal insufficiency that would influence brain development. This is exactly the case; children of mothers who have emigrated from Uganda to Sweden, for example, have an autism rate of 15%, which is 200 times that of the general population.[12]

Far less sunlight is available in Sweden than Uganda, and the season available for vitamin D production is much shorter in Sweden.
This puts the Ugandan women at a severe disadvantage in producing enough vitamin D for the developing fetus.
There is a close correlation between latitude and autism among countries; the higher the latitude, the higher the rate of autism.[13]
High-latitude countries have higher rates of vitamin D deficiency due to a shorter season in which UVB is available to stimulate its production in the skin.
The same relationship of latitude to autism exists within the states of the USA, with northern states having higher rates of autism.[14] [15]
In winter, when vitamin D production is low, birth rates of autistic children peak.[16]

Rickets and autism show similar urban/rural distribution rates.

Rickets is an accepted vitamin D-deficiency disease, and urban children have significantly higher rates of both diseases.[17]
Pregnant rural women and their children tend to be outside in the sunshine more their urban counterparts, and in urban settings, more air pollution blocks out UVB light, the wave length that stimulates vitamin D production; poor air quality is directly correlated with autism[18] and with profoundly lower serum levels of vitamin D.[19]
It is also interesting to note that the Amish of Pennsylvania mostly rural farmers have extremely low rates of autism.[20]
According to Dr. Heng Wang, who treats Amish people in rural Ohio, their rate of autism is 1 in 1,500, compared to 1 in 166 nationally.[21]

Finally, where precipitation rates are high, rates of autism are also high,[22] [23] suggesting a link with sunlight deprivation.
Cloudy, rainy weather blocks the UVB light necessary to produce vitamin D.
The argument that autism is a vitamin D-deficiency disorder is compelling, but until the theory is proven, it would certainly be prudent to assure that pregnant women and young children maintain optimal levels of vitamin D.
There is no downside, and the potential to halt an unnecessary disease that is devastating to youngsters, their parents and society.

US House Testimony June 2011

“ASD transcends geographic, economic and cultural boundaries,”
Shih said. “Current scientific consensus is that 67 million people, or about 1 % of the world’s population is affected with some form of ASD—a prevalence that is higher than AIDS, diabetes, and cancer combined.
While there is currently no known medical cure for autism, behavioral treatment programs can be quite effective, particularly when the diagnosis is made early and subsequent interventions are begun.”
