ADHD 'caused by genetic faults'

ADHD 'caused by genetic faults'
Quote:Children with the condition, thought to affect one in 50, are more likely to carry particular faulty sections of genetic code than those without it.

Researchers at Cardiff University made their conclusions after studying the DNA of 366 children diagnosed with ADHD and more than 1,000 children without it.

Anita Thapar, professor of child and adolescent psychiatry, said: "This is really exciting because it gives us the first direct genetic link to ADHD."

She added: "We hope that these findings will help overcome the stigma associated with ADHD. Too often, people dismiss ADHD as being down to bad parenting or poor diet."

Children with ADHD find it difficult to concentrate, are extremely restless and impulsive and often get into trouble at school.

But as the condition has become better known it has attracted criticism, with some saying it is merely as a politically-correct way of excusing children who are out of control due to poor parenting.

However, Prof Thapar said: "Now we can say with confidence that ADHD is a genetic disease and that the brains of children with this condition develop differently to those of other children."

She and colleagues found that children with ADHD were twice as likely as others to have small genetic segments of their DNA duplicated or missing.

While people have two copies of the vast majority of genes, one from each parent, sometimes one is missing or there are too many copies - an error known as copy number variants (CNVs). These are known to cause other brain disorders like autism and schizophrenia.

The academics found that while seven per cent of normal children had large, rare CNVs in one section of the genome, the proportion among those with ADHD was 14 per cent.

The research, published today in The Lancet, also "suggests there may be a shared biological basis" for ADHD and autism.

Although they are thought to be entirely separate disorders, the scientists found that both appear to be caused by large CNV errors in one part of the sixteenth chromosome.

Prof Thapar said she hoped attitudes to ADHD would now change, as they had done for autism: "Some years ago people were saying that autism was caused by 'refrigerator parents'. That has changed and hopefully it will change for ADHD too."

The research was unlikely to lead to a genetic test for ADHD, she said, as there were too many other genetic and environmental factors at play.

RE: ADHD 'caused by genetic faults'
I wonder, if there is a "fault" in those with reported ADHD, if it is a result of what we put into our bodies?
