"This is a step forward in ADHD research," said one of the researchers behind the study.
ADHD is an abbreviation for Attention Deficit / Hyperactivity Disorder. The characteristics of ADHD are concentration difficulties, impulsivity and hyperactivity.
In Norway, it is estimated that about 3 to 5% of children and adolescents under 18 years of age have ADHD.
The frequency varies according to age and sex, and it is the majority of boys who are diagnosed.
For many, dysfunction due to ADHD persists in adulthood, even though it is common for symptoms to diminish with age.
In Norway, diagnosis can be made in adulthood.

Researchers at the University of Bergen participated in an international research collaboration that culminated in what is supposed to be the world's largest genetics study of ADHD, reports VG.
In the study published in the journal Nature Genetics, researchers compared the genes of 20,000 participants with ADHD with the genes of 35,000 people in a control group.
The analyzes show that there are several common genetic variants associated with ADHD and that, if you have many of these variants, the likelihood of diagnosis increases.
These genes are also associated with an increased risk of dropout, overweight, depression and having children earlier than average.
– This is an advance in ADHD research. It will be much easier to understand the situation in the future , says Professor Jan Haavik at the KGB Jebsen Center for Neuropsychiatric Disorders at the University of Bergen (UiB) in VG.

I hope to change attitude
He believes that the study shows that genetic vulnerability to ADHD is greater in the individual and may be the cause.
Haavik hopes the results will change the view of the state and attitudes so that people recognize the real problems and understand that they are not bad education and low self-discipline.
– Important for people with ADHD and their families
In addition, Gry Lunde, general secretary of ADHD Norway, believes that the results could affect people with ADHD and their families.
"We continue to receive reports that parents think they are suspected of being poorly cared for or poorly educated, and believe the diagnosis is an easy solution," she told VG.
The diagnosis of ADHD will still be problematic as it is difficult to distinguish between the symptoms of post-traumatic stress disorder, loss of care and ADHD.
"But it is important that ADHD is recognized as a diagnosis and that the stigma of ADHD is scientifically proven," she told VG.
