Myth: ADHD is an American disorder.
Those who claim ADHD is an American disorder believe that ADHD is due to the pressures of living in a fast-paced, competitive American society. Some argue that if we lived in a simpler world, ADHD would not exist.
Fact: ADHD occurs throughout the world.
Wherever scientists have searched for ADHD, they have found it. They have done this by going to different countries, and speaking to people in the community to diagnose them with or without ADHD. These studies show that ADHD occurs throughout the world and that the percentage of people having ADHD does not differ between the United States and the rest of the world. Examples of where ADHD has been found include Australia, Brazil, Canada, China, Colombia, Finland, Germany, Iceland, Israel, Italy, Japan, New Zealand, Spain, Sweden, Taiwan, The Netherlands, and Ukraine. ADHD is not an American disorder.
Myth: A child who sits still to watch TV or play video games cannot have ADHD.
Many parents are puzzled that their child can sit still to watch TV or play video games for hours, but that same child cannot sit still for dinner or stay at their desk for long to do homework. Are these children faking ADHD symptoms to get out of homework?
Fact: ADHD does not necessarily interfere with playing video games or watching TV.
Because children cannot turn their ADHD on and off to suit their needs, it does seem odd that a child who is typically hyperactive and inattentive can sit for hours playing a video game. But this ability of ADHD children fits in very well with scientific facts about ADHD. First, you probably understand the effects of rewards and punishment on behavior. If your behavior is rewarded, you are likely to do it again. If it is punished, you will avoid that behavior in the future. Rewards that have the strongest effect on our behavior are large and will occur soon. For example, consider these two choices:
a) if you listen to a boring one-hour lecture, I will pay you $100 immediately after the lecture
b) if you listen to a boring one-hour lecture, I will pay you $110 one year after the lecture
Choice (a) is more appealing than choice (b). Most people will not think it is worthwhile to wait one year for $10. We say they have 'discounted' the $10 to $0.
Now consider the choices:
c) if you listen to a boring one-hour lecture, I will pay you $100 immediately after the lecture
d) if you listen to a boring one-hour lecture, I will pay you $2,000 one year after the lecture
Choice (d) is more appealing than choice (c). Most people will wait one year for$2,000. It is obvious here is that if I want the best chance of having you watch a lecture, I should offer you a large sum of money immediately after the lecture. What is not so obvious is that people vary a great deal in the degree to which they are affected by rewards that are either small or distant in the future. For some people, getting $2,000in one year is almost like getting nothing at all. We say that such people are not sensitive to distant rewards.
What does this have to do with ADHD and video games? Well, people with ADHD are usually not very sensitive to weak or distant rewards. To affect the behavior of a person with ADHD, the reward needs to be immediate and fairly large. When a child with ADHD sits down to do homework, the potential reward is getting a good grade on their report card, but they won't receive that grade for weeks or months, so it is very distant. Thus, it is not surprising that the possibility of that reward cannot control the child's behavior. In contrast, video games are created so that players are rewarded very frequently by winning points or completing one of the many levels one must pass to finally complete the game. Because playing well is also rewarded by friends, the video game rewards are strong and immediate, which makes it easy for people with ADHD to sit still and play for long periods.
Myth: ADHD disappears in adulthood.
Until the 1990s, it was commonly believed that children grew out of ADHD. The reason for this is not clear. Some theories about ADHD suggested that ADHD children had a lag in brain development, and that they would make up for that lag during adolescence. So ADHD was seen as a delay in brain development that could be overcome. The idea that children routinely recovered from ADHD was so strong that many insurance companies would not pay for the ADHD treatment of adults.
Fact: In the majority of cases, ADHD persists into adulthood.
This myth about ADHD has been proven wrong by studies that diagnosed ADHD in children and then examined it many years later than in adults. These studies showed that, although there was some recovery from ADHD, about two-thirds of cases persisted into adulthood. The studies also taught us that ADHD symptoms tend to change with age. The extreme and disruptive hyperactivity of many ADHD children gets somewhat better by adulthood, as do some symptoms of impulsivity. In contrast, inattentive symptoms do not decrease much with age.
Myth: People with ADHD cannot do well in school or succeed in life.
This myth is based on several facts: 1) ADHD affects many aspects of life; 2) ADHD impairs thinking and behavior and 3) for most people, ADHD is a lifelong disorder. Altogether, doesn't this mean that people with ADHD won't succeed in life?
Fact: People with ADHD can succeed and live productive lives.
There are two reasons why people with ADHD can succeed in life. The first is obvious. Although treatments for ADHD are not perfect, they can eliminate many of the obstacles that would otherwise make it difficult for ADHD patients to do well in school or on the job. But, more importantly, having ADHD is only one of many facts about a person's life. Some ADHD people have other skills or traits that help them compensate for their ADHD. For example, if you have a high level of intelligence, an engaging personality, or excellent athletic skills, you can do well despite having ADHD. Consider Michael Phelps, who broke so many Olympic swimming records. He was diagnosed with ADHD at age 9 and took Ritalin to help his hyperactivity. James Carville has ADHD, but he completed law school and helped Bill Clinton become President of the United States. Cammi Granato's ADHD did not stop her from becoming captain of the United States Olympic ice hockey team, and Ty Pennington's ADHD did not stop him from becoming a star on TV.
Myth: ADHD does not affect highly intelligent people
The mistake behind this myth is that it assumes that being very intelligent protects people from having ADHD. It's true that if you are highly intelligent, you can use that intelligence to compensate for some ADHD' effects, but does high intelligence completely protect a person from ADHD?
Fact: People with ADHD can succeed and live productive lives.
When my colleagues and I studied this question, we found clear evidence that high intelligence does not completely protect people from ADHD. Like people who don't have ADHD, having high intelligence will help Alderpeople do better than ADHD people who are not smart. But when we compared highly intelligent Alderpeople with highly intelligent non-ADHD people, we found that the highly intelligent ADHD people had many of the impairing problems that are known to be associated with ADHD. For details about these problems, see Complications of ADHD. In another study, we compared ADHD adults who had received straight A grades in high school, with non-ADHD people who had achieved the same grades. Despite their good grades, these ADHD adults were not doing as well in their jobs and not earning as much income as the non-ADHD adults. And ADHD also has an impact at every level of education. As you can see from the figure, even for people with college degrees, having ADHD lowers your chances of being employed.

Background:
Stimulants, such as methylphenidate and amphetamines, are currently considered effective medications for treating ADHD. However, approximately one-third of patients do not have an adequate response to these treatments. Additionally, long-term adherence is relatively low, with only about half of the patients still using methylphenidate after six years.
Recently, there has been increasing attention to the concept of microdosing with psychedelic drugs such as psilocybin and LSD. A microdose typically ranges from one-tenth to one-twentieth of a recreational dose and does not produce noticeable perceptual effects or interfere with daily activities.
The Study:
A European research team recently published the findings of the first double-blind, placebo-controlled randomized clinical trial examining the safety and efficacy of repeated low doses of LSD in adults diagnosed with ADHD.
The six-week trial took place at University Hospital in Basel, Switzerland, and Maastricht University, Netherlands. Participants, aged 18 to 65, had clinical diagnoses of ADHD with moderate to severe symptoms.
The team excluded persons with a past or present diagnosis of psychotic disorders, substance use disorders, or other psychiatric or somatic disorders likely to require hospitalization or treatments.
Participants were randomly assigned in a 1:1 ratio to receive either LSD or placebo. Neither study staff nor participants were aware of the assignments until the conclusion of the trial.
During the six-week trial, participants received twice-weekly doses on-site, amounting to a total of 12 doses. Following the first and final doses, participants were asked to determine whether they had been administered LSD or a placebo in order to assess blinding. Four weeks after the conclusion of the microdosing period, participants returned for an evaluation of the treatment's safety and efficacy.
Twenty-seven of the 53 participants were randomized to receive the LSD microdosing treatment in a liquid solution, and 26 to receive placebo. Placebo consisted of the same drinking solution, minus the microdose of LSD.
The average age was 37, and 42% of participants were female. Forty-six of the 53 participants completed the study.
Out of 29 participants, 21 from the LSD group and eight from the placebo group correctly guessed their allocation, totaling 63% overall.
As assessed through the Adult ADHD Investigator Symptom Rating Scale, ADHD symptoms improved by 7.1 points in the LSD group and 8.9 points in the placebo group, with no significant difference between them.
Regarding safety, the LSD group experienced nearly double the adverse events compared to the placebo group. None of the events in either group were classified as serious. The five most frequent adverse events were headache, nausea, fatigue, insomnia, and visual alterations, occurring around three times more frequently in the LSD group than in the placebo group.
The team concluded, “although repeated low-dose LSD administration was safe in an outpatient setting, it failed to demonstrate efficacy compared with placebo in improving ADHD symptoms among adults.”
Conclusion: Microdosing with LSD did not offer significant advantages over placebo in treating ADHD symptoms, despite being physically safe and well tolerated in the trial setting. This suggests that further research is needed to explore alternative treatments for ADHD.

Attention Deficit Hyperactivity Disorder (ADHD) is a common condition affecting children and adolescents worldwide, characterized by symptoms such as hyperactivity, impulsivity, and inattention. While traditional treatments like medication and behavioral therapy are often used, some individuals are turning to complementary and alternative therapies (CAM) for help. One such option gaining attention is acupuncture. But does it really work for ADHD?
A recent comprehensive study aimed to evaluate the effectiveness of acupuncture in treating ADHD symptoms. Here’s a breakdown of the findings, with a focus on the age groups included in the research and what these findings could mean for ADHD treatment options.
The study in question conducted a systematic review and meta-analysis (SR/MA) of acupuncture trials for ADHD, comparing its effects to traditional treatments such as pharmacotherapy and behavioral therapy. The researchers focused on acupuncture’s impact on core ADHD symptoms like hyperactivity, impulsivity, inattention, and conduct problems, while also exploring how acupuncture might help with other issues, such as learning difficulties and psychosomatic symptoms.
One key feature of this study was the inclusion of a broad age range of participants, specifically children and adolescents. These two groups are the most commonly diagnosed with ADHD, and their responses to treatments can vary significantly. Understanding how acupuncture works for these age groups is critical for evaluating its effectiveness as an ADHD treatment.
Here’s what the study found across the different age groups:
Despite these promising results, the study also highlighted several limitations:
In short, and as is so often the way of evidence-based medicine, we still can’t say with absolute certainty one way or the other. These studies may show promise in improving hyperactivity, impulsivity, inattention, and conduct problems– in both children and adolescents. However, the evidence is not yet strong enough to recommend it as a primary treatment. While it may serve as a helpful complement to standard therapies, especially for those struggling with medication side effects or access to behavioral therapy, more research is needed to establish its effectiveness.

This New York Times article, “5 Takeaways from New Research about ADHD”, earns a poor grade for accuracy. Let’s break down their (often misleading and frequently inaccurate) claims about ADHD.
The Claim: A.D.H.D. is hard to define/ No ADHD Biomarkers exist
The Reality: The claim that ADHD is hard to define “because scientists haven’t found a single biological marker” is misleading at best. While it is true that no biomarker exists, decades of rigorous research using structured clinical interviews and standardized rating scales show that ADHD is reliably diagnosed. Decades of validation research consistently show that ADHD is indeed a biologically-based disorder. One does not need a biomarker to draw that conclusion and recent research about ADHD has not changed that conclusion.
Additionally, research has in fact confirmed that genetics do play a role in the development of ADHD and several genes associated with ADHD have been identified.
The Claim: The efficacy of medication wanes over time
The Reality: The article’s statement that medications like Adderall or Ritalin only provide short-term benefits that fade over time is wrong. It relies almost entirely on one study—the Multimodal Treatment Study of ADHD (MTA). In the MTA study, the relative advantage of medication over behavioral treatments diminished after 36 months. This was largely because many patients who had not initially been given medication stopped taking it and many who had only been treated with behavior therapy suddenly began taking medication. The MTA shows that patients frequently switched treatments. It does not overturn other data documenting that these medications are highly effective. Moreover, many longitudinal studies clearly demonstrate sustained benefits of ADHD medications in reducing core symptoms, psychiatric comorbidity, substance abuse, and serious negative outcomes, including accidents, and school dropout rates. A study of nearly 150,000 people with ADHD in Sweden concluded “Among individuals diagnosed with ADHD, medication initiation was associated with significantly lower all-cause mortality, particularly for death due to unnatural causes”. The NY Times’ claim that medications lose their beneficial effects over time ignores compelling evidence to the contrary.
The Claim: Medications don’t help children with ADHD learn
The Reality: ADHD medications are proven to reliably improve attention, increase time spent on tasks, and reduce disruptive behavior, all critical factors directly linked to better academic performance.The article’s assertion that ADHD medications improve only classroom behavior and do not actually help students learn also oversimplifies and misunderstands the research evidence. While medication alone might not boost IQ or cognitive ability in a direct sense, extensive research confirms significant objective improvements in academic productivity and educational success—contrary to the claim made in the article that the medication’s effect is merely emotional or perceptual, rather than genuinely educational.
For example, a study of students with ADHD who were using medication intermittingly concluded “Individuals with ADHD had higher scores on the higher education entrance tests during periods they were taking ADHD medication vs non-medicated periods. These findings suggest that ADHD medications may help ameliorate educationally relevant outcomes in individuals with ADHD.”
The Claim: Changing a child’s environment can change his or her symptoms.
The Reality: The Times article asserts that ADHD symptoms are influenced by environmental fluctuations and thus might not have their roots in neurobiology. We have known for many years that the symptoms of ADHD fluctuate with environmental demands. The interpretation of this given by the NY Times is misleading because it confuses symptom variability with underlying causes. Many disorders with well-established biological origins are sensitive to environmental factors, yet their biology remains undisputed.
For example, hypertension is unquestionably a biologically based condition involving genetic and physiological factors. However, it is also well-known that environmental stressors, dietary
habits, and lifestyle factors can significantly worsen or improve hypertension. Similarly, asthma is biologically rooted in inflammation and airway hyper-reactivity, but environmental triggers such as allergens, pollution, or even emotional stress clearly impact symptom severity. Just as these environmental influences on hypertension or asthma do not negate their biological basis, the responsiveness of ADHD symptoms to environmental fluctuations (e.g., improvements in classroom structure, supportive home life) does not imply that ADHD lacks neurobiological roots. Rather, it underscores that ADHD, like many medical conditions, emerges from the interplay between underlying biological vulnerabilities and environmental influences.
Claim: There is no clear dividing line between those who have A.D.H.D. and those who don’t.
The Reality: This is absolutely and resoundingly false. The article’s suggestion that ADHD diagnosis is arbitrary because ADHD symptoms exist on a continuum rather than as a clear-cut, binary condition is misleading. Although it is true that ADHD symptoms—like inattention, hyperactivity, and impulsivity—do vary continuously across the population, the existence of this continuum does not make the diagnosis arbitrary or invalidate the disorder’s biological basis. Many well-established medical conditions show the same pattern. For instance, hypertension (high blood pressure) and hypercholesterolemia (high cholesterol) both involve measures that are continuously distributed. Blood pressure and cholesterol levels exist along a continuum, yet clear diagnostic thresholds have been carefully established through decades of clinical research. Their continuous distribution does not lead clinicians to question whether these conditions have biological origins or whether diagnosing an individual with hypertension or hypercholesterolemia is arbitrary. Rather, it underscores that clinical decisions and diagnostic thresholds are established using evidence about what levels lead to meaningful impairment or increased risk of negative health outcomes. Similarly, the diagnosis of ADHD has been meticulously defined and refined over many decades using extensive empirical research, structured clinical interviews, and validated rating scales. The diagnostic criteria developed by experts carefully delineate the point at which symptoms become severe enough to cause significant impairment in an individual’s daily functioning. Far from being arbitrary, these thresholds reflect robust scientific evidence that individuals meeting these criteria face increased risks for the serious impairments in life including accidents, suicide and premature death.
The existence of milder forms of ADHD does not undermine the validity of the diagnosis; rather, it emphasizes the clinical reality that people experience varying degrees of symptom severity.
Moreover, acknowledging variability in severity has always been a core principle in medicine. Clinicians routinely adjust treatments to meet individual patient needs. Not everyone diagnosed with hypertension receives identical medication regimens, nor does everyone with elevated cholesterol get prescribed the same intervention. Similarly, people with ADHD receive personalized treatment plans tailored to the severity of their symptoms, their specific impairments, and their individual circumstances. This personalization is not evidence of arbitrariness; it is precisely how evidence-based medicine is practiced. In sum, the continuous nature of ADHD symptoms is fully compatible with a biologically-based diagnosis that has substantial evidence for validity, and acknowledging symptom variability does not render diagnosis arbitrary or diminish its clinical importance.
In sum, readers seeking a balanced, evidence-based understanding of ADHD deserve clearer, more careful reporting. By overstating diagnostic uncertainty, selectively interpreting research about medication efficacy, and inaccurately portraying the educational benefits of medication, this article presents an overly simplistic, misleading picture of ADHD.
