The 12 Most Common Myths About ADHD

In the first weeks after I said I had been diagnosed, I heard the same sentences so many times that in the end I began to mix up which one came from which mouth. "But you were never restless." "Everyone's a bit like that anyway." "You were such a good student, it can't be."

None of the people who said these sentences was trying to hurt me. They circulate as old information, incomplete accounts and well-meant generalizations. Their consequences, though, are concrete: diagnosis is delayed, and while treatment is put off people go on blaming themselves. My own diagnosis waited until I was twenty-three, and part of that delay lies in the sentences on this list.

1. "ADHD is a boys' picture"

In clinical samples the proportion of boys was very high for a long time. In community samples, however, the gap narrows markedly.

The reason is not that girls have ADHD less often but that they are noticed less. The predominantly inattentive picture stands out far less than hyperactivity; a child who quietly drifts away interrupts no one's lesson. The details are in the article on ADHD in women.

2. "You grow out of it in childhood"

Symptoms change with age: hyperactivity decreases and an inner restlessness that is not visible from outside takes its place. Difficulties with attention and executive function largely continue.

The World Federation consensus statement (Faraone et al., 2021) shows that ADHD continues into adulthood in a significant proportion of people and that adult ADHD is a valid diagnosis.

The insidious side of this myth is that when an adult goes to seek help they meet the answer "that's a children's thing" and stop trusting their own observation.

3. "Everyone is a bit like that"

Everyone sometimes forgets, gets distracted, procrastinates. What decides a diagnosis is frequency, duration and the loss of function that results: symptoms must be present in more than one setting and must affect life in a measurable way.

In the glossary the heading loss of function explains this distinction. When this sentence is said to me, I think: everyone coughs sometimes, and that does not make pneumonia debatable.

4. "It is not seen in intelligent people"

There is no such relationship between ADHD and intelligence. High cognitive capacity can help cover the symptoms, and that delays diagnosis.

Behind the sentence "but you're so successful" there is usually a compensation strategy that has been maintained for years: working the night before, finishing in a panic, closing the gap with intelligence. These strategies work until the workload grows, and then they collapse.

5. "It comes from bad parenting"

The review by Faraone and Larsson (2019) shows that the heritability of ADHD is high. Family, twin and adoption studies consistently point to a strong genetic contribution.

Parenting style can affect the severity and consequences of symptoms. It is not the cause. Parents pay the highest price for this myth; they are forced onto the defensive when discussing their own child's diagnosis.

6. "It's because of sugar"

In controlled studies no finding is obtained that sugar causes ADHD symptoms. What nutrition can and cannot do I wrote about separately in the article on ADHD and nutrition.

7. "Screens cause it"

ADHD is a picture that was described long before screens entered our lives. An association is reported between screen use and ADHD, but its direction is unclear: it is also possible that people with ADHD are drawn more to screens.

That screens can worsen symptoms is a separate topic, and I took it up in the article on infinite scrolling.

8. "The medication is addictive"

The meta-analysis by Wilens and colleagues (2003) reports that the risk of substance use in later years did not increase in people treated with stimulant medication in childhood. The consensus statement also assesses the safety profile of appropriate use under medical supervision as favorable.

Misuse is a separate matter, and prescription monitoring exists for exactly that. Which medication, for whom and at what dose is decided by the doctor.

9. "Medication changes your personality"

The expected effect is on attention, impulsivity and restlessness. If a change in personality or a feeling of emotional blunting is reported, that is a sign that the dose or the medication needs to be reviewed. The details are in the article on ADHD medication treatment.

10. "ADHD has become fashionable, there is over-diagnosis"

The worldwide prevalence meta-analysis by Polanczyk and colleagues (2007) shows that ADHD is seen at similar rates across regions and that differences in diagnosis rates largely come from differences in method.

Rising awareness raises the number of diagnoses. That does not mean the diagnosis is made up. In the glossary the heading the over-diagnosis debate brings together both sides of the argument.

When I hear this claim, the question that comes to mind is: if the diagnosis is handed out this easily, why did mine wait twenty-three years?

11. "If you can focus, you can't have ADHD"

This is the most frequent wrong inference. ADHD is defined not as the absence of attention but as a difficulty in regulating attention. Being able to work for hours on a subject that interests you does not contradict the picture; in the glossary it appears as hyperfocus.

This was the myth that misled me most. Because I could sink into a subject that interested me for hours, I thought for years "so I don't have it." The problem was not that my attention did not open; it was that I could not choose where it opened.

12. "You just need to work harder"

This sentence is said to people who have already been working harder for years, and it is one of the sentences that does the most harm. The problem is not the amount of effort; it is starting and sustaining the effort.

You can share this list. Explaining the same sentences again and again is tiring. In the glossary advice fatigue describes exactly this. Sending a list like this takes far less energy than explaining from the beginning every time.

One more that is not on the list but that I hear often

There is a newer sentence that has become common in recent years: "ADHD is actually a superpower." The intention of those who say it is good; they want to move a picture that has long been discussed in terms of deficit to a positive place.

But this sentence is not exactly right either, and it has its own cost. ADHD is tied to a list of diagnostic criteria; inside that list stands the condition of loss of function. So the definition of the diagnosis already contains the item "it makes life harder." A narrative that romanticizes the struggle makes it harder to ask for support: the question comes, "if it's a superpower, why are you asking for help?"

I took up how far the strengths question is real in the article on strengths in ADHD. Briefly, where I stand is this: being able to sink for hours into a job that interests me is a real advantage, but not being able to choose when to switch it on is a real obstacle. A narrative that can hold both in one sentence feels more honest to me.

I collected the state of the evidence on causes, along with what is association and what is causation, in the article what causes ADHD.

When you hear these sentences

Most misinformation circulates with good intentions, and that is exactly why it is hard to correct. Because the person in front of you is not trying to hurt you, getting angry feels odd, and staying silent builds up inside.

Three things have worked for me. The first is not getting into an argument: most people who say these sentences are not defending a thesis, they are just repeating what they heard. The second is keeping the correct information ready at hand; sending a source I have read is both faster and less wearing than having the same conversation for the twentieth time. The third is telling apart who is really curious. It is worth explaining to the curious. Explaining to someone who is only giving an opinion uses up my energy and changes nothing on the other side.
