Researchers at the Norwegian Institute of Public Health have read the records of 549 children under the age of 12 who have been diagnosed with ADHD.
In four out of the ten files there was a mismatch between the diagnosis that was asked and what was written about the child in the magazine.
"We can not confirm that these children do not have ADHD, but what we read in the journals shows that they do not meet the diagnostic criteria," says the doctor and researcher Pål Surén.
Doctors diagnosing diagnosis often do not consider other possible explanations when a child has signs of hyperactivity, impulsivity and concentration difficulties, according to the report.
When scientists compare business environments, there appear to be significant differences that can only be explained by the different views on where to add the ADHD diagnosis list.
In Western Agder, only 1.4% of children are diagnosed at the age of 12 years. At Hedmark, the number is almost four times higher, 5.5%.
You have the most diagnoses in the country
BUP in Hamar welcomes children from the immediate area with difficulties that may indicate ADHD.
Here they investigate and map problems, talk to children, parents and teachers, and take exams. They then evaluate the diagnosis and make a treatment plan. Some of the children take medication.
Ingvild Svenkerud Aasen, head of BUP Hedmark, knows they are among those who make the most of ADHD diagnoses in the country. The danger is that they end up with ADHD before thoroughly exploring other reasons, he says.
He tells them that they are now working to improve.
– The diagnosis of ADHD is discreet. Lack of proximity and concentration difficulties is something that many children have, without ADHD.
Professionals are fighting
Psychologist and former child counselor Reidar Hjermann believes that many children are currently receiving ADHD diagnosis in Norway.
He also knows examples that professionals thought were symptoms of ADHD, later turned out to be injuries after violence.
– The diagnosis of ADHD can cover the difficult things in children's lives. Responsible adults should focus on revealing what is happening at home instead of looking for what's wrong with the child.
Diagnosis with the wrong reason can have serious consequences for children, says Hjermann, can put them on benches, affect their self-esteem, and if their diagnosis hangs, they can later foreclose them from certain high-clearance jobs .
Besides, medicines may have side effects, in some cases children become more "flattened".
"In a few decades, we will look back at the time we live now, like a day when we cured a large part of the children's population, and gave us a diagnosis that created more problems than helped them." I am convinced, says Hjermann.
It calls for clearer guidelines
Researchers at the National Institute of Public Health believe that professionals across the country need clearer guidelines than they do today must to be able to diagnose ADHD to be done.
"ADHD is generally a diagnosis that causes silence and it is much more important to be careful about research," says Pål Surén.
He does not know if there is too much ADHD diagnosis today, saying that children with severe difficulties with hyperactivity and failure to concentrate have a good effect on medication and other measures.
"We are worried that the diagnosis is being used properly and that they are the right children to take it," says Surén.
Director of the Geir-Stene Larsen Division in the Health Directorate says it is important for both the patient and the treatment that the ADHD diagnosis is on a proper basis and that the doctor has ruled out that there are other reasons why the child is having difficulty.
– This is described in the guidelines and it is therefore also important to follow them. It is worrying if this is not the case in half.
