already know that this blog is about Asperger's, but .... in many cases of Asperger ADHD is attached, so I found this article and thought it was interesting ponerlo.un greeting. Summary
A group of British scientists have found the first evidence that attention deficit and hyperactivity disorder (ADHD under the symbol) is a genetic disorder. A scan through the genetic map of more than 1,400 children, scientists found that those who suffer ADHD were more likely than others to have small pieces of DNA duplicated or lost. The findings of this research have been published in the journal The Lancet.
Anita Thapar, a professor of psychiatry who led the study, said the discovery would help to dispel the myth that ADHD is caused by impolite by parents or diets sugars. De fact informed reporters the results give us "first genetic link direct ADHD. Now we confidently say ADHD is genetic disease and brains children with this ailment develop differently those of other children. "
Thapar said findings help discover biobased ADHD "and that will be really important future developing new treatments much effective." Yet underlined that findings DNA unlikely lead develop genetic testing detecting it, because the cause could be a complex mix of genes and environment. Therefore, Philip Asherson, Institute of Psychiatry at King's College London, wanted to point out that "it is unclear which may lead to a diagnostic test, but it could open new avenues for understanding the neurobiology of the disorder."
The team analyzed the genomes of 366 children with ADHD and compared them with 1,047 samples from children without the disorder to try to find variations in genetic composition. The findings showed that variations in the number of codes were twice as common in children with ADHD than in others. Also, the study also found what they called "Substantial evidence" that ADHD is a neurodevelopmental problem, as it identified an overlap between deleted and duplicated segments of DNA, called copy number variants (CNV, its acronym in English), and genetic variants associated with disorders, autism and schizophrenia.
