Swedish ADHD debate shifts from inheritance to educational and policy priorities

A heated national discussion in Sweden explores the roots of ADHD, questioning the role of heredity versus environmental support, amid debates over diagnosis, medication, and classroom solutions.

Sweden’s increasingly public argument over ADHD has widened far beyond the clinic. What began as a dispute over how strongly the condition should be described as inherited now takes in the language used by psychiatrists, the way drug studies are reported, and whether money is being steered towards diagnoses and medication when schools themselves remain badly equipped to support struggling pupils.

That wider challenge was set out most plainly by Johan Bengtsson, a psychiatrist and researcher at Uppsala University, in an opinion article published by Kvartal on 21 August. Referring to SVT’s series Alla mina bokstäver, he highlighted senior psychiatrist Lotta Borg Skoglund’s statement that “ungefär 80 procent av risken för att man får adhd förklaras av ärftliga faktorer.” Bengtsson’s point was not simply that such claims circulate widely, but that they are often presented in public as if they settle more than the evidence can bear.

The same fault line has opened up over medication. Writing with Staffan Svensson in Dagens Arena on the same day, Bengtsson argued that coverage of a new Swedish study blurred the difference between an observed association and a proven effect. The research compared patients who started ADHD medication within three months of diagnosis with those who did not, and found that over the following two years the medicated group had lower rates of suicidal behaviour, substance misuse and crime. But the authors said several reports overstated the result by referring to suicide rather than suicidal behaviour, noting that Dagens Nyheter later changed its headline. They also said the study’s comparison was weakened by leaving out people who stopped taking medication.

Socialstyrelsen’s national guidelines offer a more measured official picture than either camp’s slogans. The agency says the number of ADHD diagnoses is expected to keep rising, and with it demand for medicines. It projected that regional spending on ADHD drugs would increase from 1.1 billion kronor in 2022 to 1.5 billion kronor in 2025, while also warning that follow-up of treatment needs to increase. For people with ADHD who also have substance-use disorders, the medicines are given a high priority because they reduce ADHD symptoms. Even so, Socialstyrelsen says there is no scientific support for claiming that treatment makes patients abstain from narcotics. The agency also points to large regional differences in access to care and in prescribing to children that seem to reflect clinical practice as much as population need.

The parliamentary evidence gathered this year has pulled the argument further towards the school system. In a report published by the education committee in March, the Riksdag found that pupils with neuropsychiatric diagnoses had poorer outcomes than pupils without them across several measures. In the 2023/24 school year, six in ten pupils with NPF reached eligibility for upper-secondary vocational programmes, compared with nine in ten pupils without NPF, and results had deteriorated over the five years examined, especially among girls. The report also found a strong link between parental education and school performance, but added that about four in ten of the schools where pupils with NPF did relatively well did not, on average, have highly educated parents.

That mattered because the same report did more than document disadvantage. In case studies of three schools with comparatively good results, the committee identified a cluster of recurring features: calm classrooms, clear boundaries, low staff turnover, routines for spotting needs early, and a shared commitment among staff to adjust teaching when a pupil was not managing. Some of the schools also used small-group teaching and, at times, two teachers. The report’s conclusion was that successful support for pupils with NPF often rests less on special add-ons than on getting the ordinary work of school right.

At a public hearing in the Riksdag on 31 March 2026, that case was made in even starker terms. Representatives from bodies including Riksförbundet Attention, Skolverket, Socialstyrelsen, the Specialpedagogiska skolmyndigheten and Sveriges Elevkårer were invited to give evidence. Jonatan Lamy of Sveriges Elevkårer told MPs that using diagnoses as the main explanation “kostar väldigt mycket pengar” in assessments and investigations, money that could instead go directly to support. He said help should be based on need rather than diagnosis and described the lessons from the three school case studies as “inte raketforskning”: low staff turnover, early intervention, clear rules and adults who do not give up on individual pupils.

SVT’s reporting on 10 April showed how politically live that message had become. Niklas Sigvardsson, a Social Democrat deputy member of the education committee and a trained teacher, called the situation “en total katastrof” and said Swedish schools had failed for years to meet the needs of pupils with NPF diagnoses. He repeated the committee’s finding that four in ten pupils with ADHD or autism did not qualify for upper-secondary vocational study in 2023/24, compared with one in ten pupils without NPF. In his view, clearer structures, more money and stronger knowledge of NPF are all needed after years of underfunding.

The row now running through Swedish media, medicine and politics is therefore bigger than a single heredity figure. One side argues that biological vulnerability is well enough established that children and adults should not be left without assessment or treatment while institutions slowly improve. Bengtsson and those backing his critique say public discussion has turned group-level findings into a more deterministic story than the evidence justifies, and that social outcomes are too easily recast as medical ones. What Parliament’s own reports and Socialstyrelsen’s guidance make harder to dismiss is a narrower but important point: the ADHD debate is also a debate about whether Sweden is willing to invest as seriously in classroom order, staffing stability and early support as it does in diagnosis and medication.
