In Switzerland, attention to attention deficit drugs are increasingly prescribed to adults. But there are significant differences between the cantons.

Few diagnoses are the subject of as much controversy as attention to attention deficit, or ADHD. For some, it rhymes with explanation and relief, for others, it is simply a fashionable pain.
A disturbance especially recognized in children
The famous British cook Jamie Oliver would be reached, just like the pop singer Taylor Swift or the tennis player Serena Williams. It would have been even posthumously detected in Léonardo da Vinci.
ADHD has long been considered a typical infantile disease. A few years ago, it was thought that its symptoms; Inattention, hyperactivity and impulsiveness disappeared with age. Undine Lang, director of the adult clinic of university psychiatric establishments in Basel, indicates:
“We know today that certain symptoms persist in adulthood in up to 70% of cases”
However, an absence of treatment in adults can have considerable consequences on professional and private life. Among them: an increase in the risk of road accidents. The probability of suffering from mental disorders is also much more important.

Blatant differences between the cantons
The higher the ADHD in adults has been publicized, the more demand for diagnosis and treatment has increased. The prescription of adult drugs has thus increased sharply: it has been multiplied by 2.5 in ten years in Switzerland. While in 2015, there were 2.3 daily doses for 1000 adults, this figure increased to 5.8 in 2023.
And the cantonal differences are striking: according to the Swiss Atlas of Health Services, Basel-Ville comes first with 9.1 daily doses per 1000 adults, seven times more than Ticino, which ends in last position with 1.3 doses. Should we conclude that Ticino treats too little, or the other cantons treat far too much?
The answer is complex. It is estimated that 2 to 3% of adults suffer from ADHD. But the fact that they get cared for depends on multiple factors.
According to the Cantonal Ticino doctor Giorgio Merlani, the low frequency of prescription for ADHDD medication in the canton has already been established. It notes the existence of a north-south ditch that is found at the continent: the European countries in the North tend to tend to prescription rates much higher than those of the South. He declares:
“According to the analyzes, we cannot speak of a clinically attested sub-registration in Ticino”
Curiously, Basel-Ville also does not see a reason to worry. For the Department of Health:
“Clinics and doctors established in the canton consider to our knowledge that the needs are covered”
Zug, third in the ranking, reports a level of prescription comparable to that of his neighbors, Zurich and Argovie. “Nothing abnormal therefore, in our opinion”.
Less stigma in the city
These disparities around ADHD do not surprise the psychiatrist undine Lang. She explains that stigma is less strong in an urban environment, which facilitates access to psychiatry:
“In Basel, for example, people are very open to the idea of asking for help”
At the same time, cities have more risk factors: migration, loneliness, high performance injunction. Epidemiological studies show that psychic diseases develop more in cities like Geneva or Basel, and ADHD is no exception to the rule.
A cultural question
But in Ticino, it is also culturally that it seems to be playing. According to experts, there is a greater tolerance for typical ADHD behavior. This results in lower prescription rates, although, according to the latest confederation report on mental health, 6.9% of the Ticino population declares to present symptoms of ADHD. By way of comparison, this figure is 5% in German -speaking Switzerland.
The fact that the symptoms lead to a diagnosis therefore also depends on the search for help by the persons concerned. Undine Lang explains:
“As a rule, patients come to see us with a concrete suspicion, and we only diagnose after a standardized examination.”
But that does not always lead to taking medication. Those against ADHD certainly count among the most effective in psychiatry, underlines the expert. But behavioral therapy also works, in particular in the least serious cases. According to the doctor, the decisive factor remains suffering, which strongly depends on living conditions, in particular on professional or family requirements.
When should you treat?
The use of drugs is emblematic many treatments in Switzerland, for which we observe marked differences between the regions. This is precisely what Stefan Essig Studies, doctor and epidemiologist at the Lucernois Research Institute and Epidemiologist, as part of a project in collaboration with cantons and health professionals. The objective: to determine the origin of these differences and if they are justified on the medical level.
“In Switzerland, we are only at the very beginning of research on this subject. And we don’t know much about the quality or need for treatments ”
Stefan Essig
However, this information would be precisely essential to assess whether there is under or above. “You have to know if it’s worth it,” adds the specialist. We can only talk about appropriate care if treatment has real health benefit and takes into account patient preferences.
So far, explains Stefan Essig, only a few isolated initiatives have been taken to examine these more in -depth correlations. But the pressure increases:
“The system’s equity and efficiency requirements are increasingly high, as is the desire to look more closely.”
