A new one for the “might cause Autism” list … Winter Conception.
A new study has revealed that those conceived in winter have up to a16 per cent greater risk of autism than those conceived in July.
- Air Pollution (Mercury in air pollution = more autism)
- Anti-Depressants (Mom on autism = more autism)
- Birth Weight HIGH (more weight = more autism. Related, see big head.)
- Birth Weight LOW (less weight = more autism)
- Brain size (Bigger brains = more autism)
- Brain Cells (Too many neurons = more autism)
- Cell phones (More cell phones = more autism)
- Clever Parents (Smart parents = more autism)
- Clomid (Clomid = more autism, see IVF)
- Closely Spaced Births (Born soon after sibling = more autism)
- Complications at Birth (Catch all, any complication = more autism)
- Father’s age (older dad = more autism)
- Genetic (squirrely genes = more autism)
- Highways (Mom lives near freeway = autism twice as likely)
- Internet (Increased Internet usage = more autism)
- IVF (Invitro Fertilization) - (IVF = More autism)
- Lead (More lead exposure = more autism)
- Lyme Disease (linked to autism)
- Metabolism (Poor metabolism = more autism)
- Missing DNA (missing DNA in boys = more autism)
- Mother’s age (older mom = more autism)
- Neanderthals (Evolution vaguely linked to autism)
- Pasteurized Milk (Pasteurization = more autism)
- Pesticides (More pesticides = more autism)
- Premature birth (Premature baby = more autism)
- Rainfall (higher precipitation areas = more autism)
- Smoking (Mom smoking during pregnancy = more autism)
- Television (More TV watching = more autism)
- Tylenol (More Tylenol = more autism)
- Vinyl Flooring (House with vinyl flooring = more autism)
- Winter Conception (Mom and Dad get busy in the Winter = more autism)

Autism: The Eusocial Hominid Hypothesis
ReplyDeleteAbstract:
ASDs (autism spectrum disorders) are hypothesized as one of many adaptive human cognitive variations that have been maintained in modern populations via multiple genetic and epigenetic mechanisms. Introgression from “archaic” hominids (adapted for less demanding social environments) is conjectured as the source of initial intraspecific heterogeneity because strict inclusive fitness does not adequately model the evolution of distinct, copy-number sensitive phenotypes within a freely reproducing population.
Evidence is given of divergent encephalization and brain organization in the Neanderthal (including a ~1520 cc cranial capacity, larger than that of modern humans) to explain the origin of the autism subgroup characterized by abnormal brain growth.
Autism and immune dysfunction are frequently comorbid. This supports an admixture model in light of the recent discovery that MHC alleles (genes linked to immune function, mate selection, neuronal “pruning,” etc.) found in most modern human populations come from “archaic” hominids.
Mitochondrial dysfunction, differential fetal androgen exposure, lung abnormalities, and hypomethylation/CNV due to hybridization are also presented as evidence.
Big brains from Neanderthals explains the origin of an autism subgroup characterized by abnormal brain growth?
DeleteThat doesn't sound credible. Cro-Magnons had a larger cranial capacity than Neanderthals on average. This was normal brain growth for the adaptations required at that time in prehistory for the ancestors of man. It has nothing to do with autism.
What in the world does a eusocial hominid have to do with the cause of Autism, and what is a eusocial hominid, a Neanderthal?
Is this a serious reply, or is this an hypothesis you found on the internet that you are you suggesting is another silly cause that should be added to the list?
Some of those reasons sound liegit. The other half I'd question.
ReplyDeleteExample: Legit: Mercury and Pesticides.
Silly reasons Baby born in December/January than July/August and Neaderthals.
"Silly reasons Baby born in December/January than July/August and Neaderthals."
DeleteI repeat:

I liked this post and linked to it. You've clearly done some research. Thanks for that! One I didn't see on your list I remember hearing publicized was the theory that vaccines cause autism. I forget which vaccine was targeted. This enjoyed a vogue several years ago, but I read more recent studies all tended towards debunking this theory. I think the actress Jenny McCarthy was using her celebrity to popularize this particular theory for a while. Not sure if she addressed the science seeming to put the kibosh to that theory and gave up the anti-vaccine campaign or not.
