Why are children with attention deficit hyperactivity-infected disorder (ADHD)?
On December 2, 2013, the results of a study that was published in the journal Pediatrics (USA), to unravel more of these factors can increase the risk of attention-deficit hyperactivity disorder (ADHD) in children.
Why are children with hyperactivity?
In the study, the scientists examined medical records of nearly 13,000 children and adults who are born in Western Australia and has used the drugs stimulate as Ritalin and Adderall to treat ADHD symptoms from 2003 to 2007.
The researchers conducted a comparison of participants with more than 30,000 other children to learn whether there are any differences in the factors that cause ADHD.
Dr. Carol Bower, researchers of the center for child health research at the University of Western Australia, the author of the study, said: “compared with mothers who have children without ADHD, the mothers have children with ADHD are more likely to be younger, single, smoking during pregnancy, suffered some complications in pregnancy and childbirth or premature birth “.
The researchers found that girls are less likely to suffer from ADHD if the mother was added to the hormone oxytocin to pull off the birth time. While previous studies have said that the use of the hormone oxytocin during childbirth increases the risk of children with ADHD.
Dr. Tanya Froehlich, Professor at children’s Hospital Medical Center in Cincinnati (USA) said the causes of ADHD has not been well understood, although evidence suggests that genes play an important role in causing ADHD. Many previous studies have found a relationship between children with ADHD with the smoking, drinking, prematurity and complications in pregnancy and childbirth in mothers.
The researchers said the condition of children with ADHD has become so popular in the USA. A survey published in November 2013 showed that 10% of American children have been diagnosed with symptoms of ADHD.
ADHD is often common in boys. The symptoms of ADHD include easy distracted, restless, hyperactive and lose focus.
