ASD and Intellectual Deficit weakly correlated

Correlation is not cause but this fact is disturbing

  • There was a strong link in this study between the incidence of autism spectrum disorder and the rate of congenital malformations of the reproductive system, which was used as a surrogate for environmental exposure of parents to unmeasured developmental risk factors, including toxins.
  • The state-mandated rigor of diagnosis of autism spectrum disorder for consideration in the special education system was also predictive of a considerable decrease in the incidence of autism spectrum disorder.

Sex Differences in the Brain, Behavior, and Neuropsychiatric Disorders

Sex differences in the brain are reflected in behavior and in the risk for neuropsychiatric disorders. The fetal brain develops in the male direction due to a direct effect of testosterone on the developing neurons, or in the female direction due to the absence of such a testosterone surge. Because sexual differentiation of the genitals takes place earlier in intrauterine life than sexual differentiation of the brain, these two processes can be influenced independently of each other. Gender identity (the conviction of belonging to the male or female gender), sexual orientation (heterosexuality, homosexuality, or bisexuality), pedophilia, sex differences in cognition, and the risks for neuropsychiatric disorders are programmed into our brains during early development. There is no proof that postnatal social environment has any crucial effect on gender identity or sexual orientation. Structural and functional sex differences in brain areas, together with changes in sex hormone levels and their receptors in development and adulthood, are closely related to sex differences in behavior and neuropsychiatric disorders. Knowing that such a relationship exists may help bring about sex-specific therapeutic strategies.

Wild rabbit brain and modern human brain

"The brains of rabbits raised in hutches are 15-30% smaller than in wild rabbits that develop their wits and skills " 
Charles Darwin, 1871

"Looking at human  for the past 200,000 years, Lahr looked at the size and structure of the bones and  found across Europe, Africa and Asia. What they discovered was that the largest Homo sapiens lived 20,000 to 30,000 years ago with an average weight between 176 and 188 pounds and a  of 1,500 cubic centimeters.
They discovered that some 10,000 years ago however, size started getting smaller both in stature and in brain size. Within the last 10 years, the average human size has changed to a weight between 154 and 176 pounds and a brain size of 1,350 cubic centimeters.
While large size remained static for close to 200,000 years, researchers believe the reduction in stature can be connected to a change from the hunter-gatherer way of life to that of agriculture which began some 9,000 years ago."

Numerus clausus, Levinas

"La guerre de 1914 pousse la famille à fuir en Russie à Kharkov (Ukraine) jusqu'en 1920. Il vit donc la révolution russe de 1917, à onze ans, en Ukraine. C'est à Kharkov qu'Emmanuel Levinas entre au lycée, malgré le numerus clausus permettant à seulement cinq enfants juifs d'y être admis. Il y lit les grands écrivains russes, notamment Pouchkine, Lermontov, Tolstoïet Dostoïevski, mais aussi Shakespeare."

Mais aussi

Policemen in the ER

This interview is so stupid that it deserves only to mention that dangerous patients should not be allowed to target doctors or nurses. This is precisely a police business.
