ADHD and Autism increase driven by an interaction between populations This website theorises that the conditions of ADHD and Autism are increasing with ethnic diversity. I provide information that ADHD and Autism are highest among mixed race people. I believe that aswell as ADHD and Autism increasing when races mix it is also increasing when sub races mix. i.e when a Nordic European mates with a Mediterranean European. ADHD This graph taken from MCHB cleary shows mixed race people have the highest recorded rates of ADHD. This is a fact. http://mchb.hrsa.gov/nsch07/national...es/05adhd.html
It shows that mixed race people have the highest rates of ADHD. I believe that as well as races mixing creating an increase in ADHD it also increase when sub races mix. For example when a German mixes with an Italian or when a russian mixes with an Irish person. I believe Britain and America have higher rates of ADHD than in Europe because they are made up of many different ethnicities compared to say a german who is normally just ethnically German or an Irishman who is normally just ethnically Irish. I must point out that the vast vast majority of cases of ADHD are long term hereditary and have little to do with my theory. The cases of ADHD I am talking about are new cases that come from nowhere, where both parents dont have any signs of ADHD. I am not saying it accounts for all new case of ADHD but it does account for some. I call ADHD where it is not earned through hereditary (Non-hereditary ADHD). AUTISM This census study shows that in California in the year 2000 mixed race people accounted for 2.6% of the population, yet in 2002 accounted for 13.50% of all autism cases which is very high.

http://www.dds.ca.gov/Autism/docs/AutismReport2003.pdf see page 19 (Other are basically mixed race). There is also this other information I have found that children of immigrants are more likely to have autistic children. http://autismnaturalvariation.blogspot.com/2008/07/are-children-of-first-generation.html The thing is that a link between autism and immigration has been suspected since at least the 1970s, even though it apparently never became an area of research that interested many investigators. Let me just quote from some abstracts, in chronological order. Harper & Williams (1976): "In a survey on the occurrence of infantile autism in New South Wales it was found that 21-9% of children had at least one foreign-born parent whose native language was not English." Gillberg et al. (1987): "Urban children with autism more often than age-matched children in the general population had immigrant parents from 'exotic' countries." Gillberg et al. (1995): "The prevalence for autistic disorder in Göteborg children born to mothers who were born in Uganda was 15% which is almost 200 times higher than in the general population of children." Gillberg & Gillberg (1996): "Fifteen of these children (27%) were born to parents, at least one of whom had migrated to Sweden." Bernard-Opitz et al. (2001): "Discussion focuses on possible risk factors and psychosocial adversities for autism such as a high frequency of caregivers who are foreign maids, the use of multiple languages and the high level of punitive educational practices." Lauritsen et al. (2005): "An increased relative risk of 1.4 was found if the mother was born outside Europe, and in children of parents who were born in different countries." Maimburg and Vaeth (2006): "The risk of infantile autism was increased for mothers aged >35 years, with foreign citizenship, and mothers who used medicine during pregnancy." Kolevzon et al. (2007): "The parental characteristics associated with an increased risk of autism and autism spectrum disorders included advanced maternal age, advanced paternal age, and maternal place of birth outside Europe or North America." There are reports along these lines from Canada as well. In fact, this was discussed in Interverbal's discussion of critiques of Fombonne et al. (2006). Now, the first thing we need to ask ourselves about these findings is whether they document an actual phenomenon or an artifact. Is there a confound that explains the apparent association? But if in fact there's an association, what explains it? We don't really know. You will find some unsubstantiated speculation based on old ideas in the cited abstracts, some speculation that I'm sure many readers will find objectionable. It's not surprising to find these types of explanations in old papers, though. If I may engage in some speculation of my own, based on newer ideas, I would say that maternal stress during gestation – see Kinney et al. (2008) – cannot be discounted. Finally, I'd like to bring attention to Roberts et al. (2007), a study claiming to associate autism with proximity to agricultural pesticide applications in the California Central Valley. The authors stated that they could not dismiss the possibility that the women studied may be disproportionately employed in agriculture. It just so happens that immigrant women also tend to be disproportionately employed in agriculture. Q. Could this be because immigrants are more likely to be ethnically mixed? A. I expect it is because immigrant cuples are more likely to come from different locations and therefore be ethnically different. Q. Why havent experts investigated the immigration link more? A. They do not want to find a link between race and Autism it goes against modern political ideals. Q. Surely its because immigrants have more vaccines than the general population? A. No it can not be . Vacines have been disproven as a cause of Autism. Q. Ive seen new studies that dont show mixed race people having a high rate of autism whys that then? A. I am very suspicious of these new studies. |
