Having ADHD might be beneficial to a group of nomads in Kenya, yesterday’s Science Daily reports. Nomadic tribesmen who have an ADHD-variant of the gene DRD4 fare better have better health than those without it, but when they settle, they become malnourished. DRD4 codes for a receptor for dopamine; according to Dan Eisenberg, an anthropology […]
More genetics news today: Researchers have identified the mutated gene that causes childhood absence epilepsy (CAE).
The seizures of childhood absence epilepsy (CAE) are usually staring spells during which the child is not aware or responsive. The child’s eyes may roll up briefly. Each spell lasts about 10 seconds and ends abruptly. The child often is […]
Mutations in the MeCP2 gene are known to cause Rett Syndrome, which causes impairments in language and cognitive and fine motor skills; according to the International Rett’s Syndrome Foundation, Rett Syndrome is often misdiagnosed as autism. Scientists have previously thought that the MeCP2 gene repressed other genes—switching them “off”; a study published in the June […]
At the 290th comment in the discussion about Adam Race and the priest restraining order, a question was asked about neurodiversity. The most recent New York Magazine has a long article by writer Andrew Solomon about, indeed, neurodiversity, the view that autism is not an illness, but a difference and a different way of […]
I never got around to making a list of last week’s top posts last week so here’s two weeks of “top posts” about autism. Rather than arrange them in chronological order, I’ve arranged them by topic:
My son Charlie turned 11 last Thursday, on May 15th. Life on the road with Charlie is my constant theme […]
A new study in the May 15th Biological Psychiatry has found genetic links to the “impaired social behaviors” of autistic children. Researchers from Yale University studied six genes “known to be involved in maternal and affiliative behaviors”; they suggest that two neurohormones which are linked to affiliative behaviors in animals, prolactin and oxytocin, are linked […]
Researchers at Adelaide’s Women’s & Children’s Hospital and the University of Adelaide, Australia, have found that a mutant gene causes epilepsy and intellectual disabilities specific to women. As noted in Science Daily, the study links a “large family of genes known as protocadherins with a condition known as ‘epilepsy and mental retardation limited to females’ […]
What do TV, ultrasounds, insufficient vitamin D, air pollution, a mother having the flu while pregnant, mercury, have to do with each other?
All have been named as possible causes of autism. TK Kenyon looks at the puzzling spectrum of research into the cause of autism, some of which he labels as “just plain stupid”—the theory […]
In the past several months, more and more scientific studies have added evidence that disputes a link between thimerosal and rising autism rates, and that link autism to mercury. Concurrently, a number of studies offer further evidence about genetic of factors and autism. Also at the same time, proponents of the view that some external, […]
“And then the guilt starts again because I have brain-eating blood that attacked Hayden.”
So says Dee Cogdill of Benton, Ohio in the April 21st Cleveland Banner; Hayden is 11 years old and autistic. Cogdill and her husband, Ed, took Hayden to Johns Hopkins University to participate in a research study about maternal antibodies (more about […]
