Researchers at the University of Bergen have participated in the world's largest genetic study of ADHD. Their results show that ADHD is biologically rooted.

This is what the Norwegian newspaper writes on its website.


Breakthrough in research

They write further:

This is a breakthrough in research on ADHD. It will be much easier to understand the condition in the future, says Professor Jan Haavik at KG Jebsen Center for Neuropsychiatric Disorders at the University of Bergen (UiB).

The study which refers to was carried out in collaboration with several international research centers. It included 20.000 people with ADHD in addition to the 35.000 people who made up the control group.


ADHD is not about poor upbringing writes:

They find several common genetic variants associated with ADHD. If you have many of the variants, the probability increases that you have the diagnosis.

Haavik elaborates to

We show that some people have a higher genetic innate vulnerability to ADHD and what ADHD can cause, and we hope it can change the view of the condition. It is not about bad upbringing or attitudes, says Haavik.


Different degrees of hyperactivity

In it is pointed out that there are different views on what ADHD is: 

Most researchers view ADHD as a condition that causes those who are diagnosed to vary along a range of hyperactivity.

The most extreme are those who reject this completely, and believe ADHD is due to poor upbringing and little self-discipline. This study is the first to disprove this.


Want a change of attitude

The researchers behind the ADHD study hope that they can help influence attitudes to ADHD in society. Haavik tells

People with ADHD often have a difficult life. When their problems are not recognized as real, at least it will not be easier for these people to deal with the difficulties. 

The article also mentions that there are still many difficult evaluations (including differential diagnoses) in the clinical work with ADHD in the health services system.
