While in the USA, about one in ten kids and a record number of adults are diagnosed with ADHD, in Europe, it's officially considered a rare diagnosis. Americans aren't born with different brains—they just approach ADHD differently.
"My whole life, I had a really bad relationship with myself. I didn't get why some things seemed to come so easily to others. Why am I always rushing, losing track, forgetting stuff, living in shame and anxiety?"
That's how Martina felt until she found out as an adult that she had ADHD, a disorder with hyperactivity and impulsivity. In her childhood and teen years, she suffered a lot. She grew up in Slovakia when ADHD wasn't talked about much by doctors. Compared to the U.S., diagnosis in Europe is still lagging behind.
While about every tenth child and a record number of adults have an ADHD diagnosis in the U.S., in Europe it's considered very rare according to official numbers. It's not like Americans are born with a different brain—they just approach ADHD differently.
The differences lie in who names it, who treats it, and who overlooks it. Where you're born with ADHD often determines if and when doctors confirm this diagnosis for you.

Had Symptoms Most of Her Life
"Most of my life, I only saw ADHD as something affecting naughty little boys. When experts started talking more about how girls can have ADHD too, I started reading about it, and suddenly everything made sense," says Martina.
She was often late to school, disrupting others, or on the flip side, sleeping in the back row. She got the nickname "Confused Maťa." She sought help after college when her symptoms got noticeably worse. She was diagnosed in London, where she moved after her studies.
She says she was lucky: "I asked for a diagnosis before the media started highlighting ADHD a lot. I waited about six months—these days, patients in England are waiting years for a diagnosis."
It's similar in other European countries. About 55% of people get their diagnosis within six months. In the U.S., doctors actively search for cases. ADHD is diagnosed not only by psychiatrists but also by pediatricians and general practitioners. Almost all patients learn about their diagnosis within half a year.
Open Discussion, Different Diagnostic Approach
After just a few months in the U.S., I realized that ADHD is talked about a lot more here than in Europe. It's not unusual for children to be tested if there's the slightest suspicion. Teachers in schools also take notice and communicate any concerns to the parents. Adults are chill about it and might say something like, “Oh, it is my ADHD brain”—which translates to “Oh, that's my ADHD brain.”
In the U.S., they use a different, more flexible diagnostic method than in Europe. It's called DSM-5, and its rules are set by the American Psychiatric Association. American doctors look for issues with inattention, hyperactivity, and impulsivity in diagnosing ADHD. Someone doesn't need to suffer from all three symptoms at once to get diagnosed.
Europe traditionally relied on the international ICD-10 classification from the World Health Organization, where diagnosed individuals had to meet all the symptoms. This is gradually changing, and Europe is moving toward the new ICD-11, which is closer to the American diagnosis.
Different approaches and diagnostic speeds lead to significant differences. Global research shows that the prevalence of ADHD is roughly the same worldwide. About 8% of children and 2.5-6% of adults in the global population have attention disorders. However, the number of diagnosed cases doesn't fully reflect reality, neither in the U.S. nor in Europe.
Official U.S. data states that 11% of children have ADHD, while in Europe it's often less than 5%, depending on the country. In the U.S., due to the high incidence, there are debates about whether they're over-diagnosing even healthy kids.
Adults are an even more complicated group, and doctors often underestimate diagnoses in them. While problematic behavior in children is noticed right away, adult symptoms are less visible. They often hide them, feeling ashamed.
"My whole life, I had a terrible relationship with myself and couldn't understand why some things came so easily to others. Like going to bed or getting up in the morning, being on time, or meeting deadlines. Why am I constantly rushing, losing track, forgetting, living in shame and anxiety? Getting answers to lifelong questions is truly freeing," Martina describes her feelings after learning she had ADHD.
Medication as the First Option
Experts agree that increased awareness has significantly contributed to the rise in cases in recent years. The high demand for diagnosis and treatment has led to scheduling issues and long waiting times in places like England. In the U.S., they've felt a shortage of medication. Treatment approaches also vary significantly.
In the United States, medication is often the first option, even for young children. Patient comfort and improving performance at school or work are top priorities. European experts aim for a more holistic approach and are more conservative in prescribing medication, often using it as a last resort.
Martina hasn't started medication yet but uses various coping mechanisms:
"I'm learning to ask for help when I need it, take regular breaks, and set boundaries. My favorite method is 'body doubling,' where you do dreaded tasks with someone. If no one's around, I use the app Dubbii—it's a total hit!"
The differences between the U.S. and Europe regarding ADHD aren't about brains but culture and approach. Americans can quickly identify and treat differences, while Europeans often downplay or delay them. Diagnosis is influenced by performance pressure, school norms, stigma around mental health, and attitudes toward medication.
"I feel great joy now that I can build my life knowing my limits and strengths. I no longer have the same expectations of myself as I used to, I’m not as hard on myself, and I see the endless chaos as a price for a brain full of ideas, empathy, and justice," Martina concludes.
