Myth: The ADHD diagnosis is very much "in the eye of the beholder."
This is one of many ways in which the ADHD diagnosis has been ridiculed in the popular media. The idea here is that because we cannot diagnose ADHD with an objective brain scan or a blood test, the diagnosis is "subjective" and subject to the whim and fancy of the doctor making the diagnosis.
Fact: The ADHD diagnosis is reliable and valid.
The usefulness of a diagnosis does not depend on whether it came from a blood test, a brain test, or from talking to a patient. A test is useful if it is reliable, which means that two doctors can agree on who does and does not have the disorder, and if it is valid, which means that the diagnosis predicts something important to the doctor and patient, such as whether the patient will respond to a specific treatment. Many research studies show that doctors usually agree about who does and does not have ADHD. This is because we have very strict rules that one must use to make a diagnosis. Much work over many decades has also shown ADHD to be a valid diagnosis. For details see: Faraone, S. V. (2005). The scientific foundation for understanding attention-deficit/hyperactivity disorder as a valid psychiatric disorder. Eur Child Adolesc Psychiatry, 14, 1-10. The short story is that the diagnosis of ADHD is very useful for predicting what treatments will be effective and what types of problems ADHD patients are likely to experience in the future.
Myth: ADHD is not a medical disorder. It's just the extreme of normal childhood energy
Mental health professionals use the term "disorder" to describe ADHD, but others argue that what we view as a disorder named ADHD is simply the extreme of normal childhood energy. After all, most healthy children run around and don't always listen to their parents. Doesn't the ADHD child or adult simply have a higher dose of normal behavior?
Fact: Doctors have good reasons to describe ADHD as a disorder
The idea that the extreme of normal behavior cannot be a disorder is naïve. Consider hypertension(high blood pressure). Everyone has blood pressure, but when blood pressure exceeds a certain value, doctors get worried because people with high values are at risk for serious problems, such as heart attacks. Consider depression. Everyone gets sad from time to time, but people who are diagnosed with depression cannot function in normal activities and, in the extreme, are at risk of killing themselves. ADHD is not much different from hypertension or depression. Many people will show some signs of ADHD at some times, but not all have a "disorder." We call ADHD a disorder not only because the patient has many symptoms, but also because that patient is impaired, which means that they cannot carry out normal life activities. For example, the ADHD child cannot attend to homework or the ADHD adult cannot hold a job, despite adequate levels of intelligence. Like hypertension, untreated ADHD can lead to serious problems such as failing in school, accidents, or an inability to maintain friendships. These problems are so severe that the center for Disease Control described ADHD as "serious public health problem."
Myth: The ADHD diagnosis was developed to justify the use of drugs to subdue the behaviors of children.
This is one of the more bizarre myths about ADHD. The theory here is that to sell more drugs, pharmaceutical companies invented the diagnosis of ADHD to describe normal children who were causing some problems in the past.
Fact: ADHD was discovered by doctors long before ADHD medications were discovered.
People who believe this myth do not know the history of ADHD. In 1798, long before there were any drugs for ADHD, Alexander Crichton, a Scottish doctor, described a "disease of attention," which we would not call ADHD.ADHD symptoms were described by a German doctor, Heinrich Hoffman, in1845 and by a British doctor, George Still, in 1902. Each of these doctors found that inattentive and overactive behaviors could lead to a problem that should be of concern to doctors. If they had had medications to treat ADHD, they probably would have prescribed them to their patients. But a medication for ADHD was not discovered until 1937 and even then, it was discovered by accident. Dr. Charles Bradley from Providence, Rhode Island had been doing brain scanning studies of troubled children in a hospital school. The scans left the children with headaches that Dr. Bradley thought would be relieved by an amphetamine drug. When he gave this drug to the children after the scan, it did not help their headaches. However, the next day, their teachers reported that the children were attending and behaving much better in the classroom. Dr. Bradley had accidentally discovered that amphetamine was very helpful in reducing ADHD symptoms, and amphetamine drugs are commonly used to treat ADHD today. So, as you can see, the diagnosis of ADHD was not "invented" by anyone; it was discovered by doctors long before drugs for ADHD were known.
Myth: Brain scans or computerized tests of brain function can diagnose ADHD.
Someday, this myth may become fact, but for now, and shortly it is a solid myth. You may think this is strange. After all, we know that ADHD is a brain disorder and that neuroimaging studies have documented structural and functional abnormalities in the brains of patients with ADHD. If ADHD is a biological disorder, why don’t we have a biological test for the diagnosis?
Fact: No brain test has been shown to accurately diagnose ADHD.
ADHD is a biologically based disorder, but there are many biological changes and each of these is so small that they are not useful as diagnostic tests. We also think that there are several biological pathways to ADHD. That means that not all ADHD patients will show the same underlying biological problems. So for now, the only officially approved method of diagnosing ADHD is by asking patients and/or their parents about ADHD symptoms as described in the American Psychological Association's Diagnostic and Statistical Manual

A recent study from Istanbul sheds light on how psychiatric admissions and diagnoses changed during the first few months of the pandemic compared to previous periods, offering critical insights for parents, clinicians, and policymakers.
This study, conducted by a team of researchers led by Ozalp Ekinci, examined psychiatric admissions among children and adolescents during 2019 and 2020.
By looking at diagnosis rates for various psychiatric conditions, the researchers aimed to pinpoint shifts in the mental health landscape as a direct response to the pandemic.
The analysis revealed several notable trends in psychiatric diagnoses among children and adolescents:
This study’s findings highlight some key takeaways that can guide mental health support efforts for children and adolescents:
As we continue to see the effects of the COVID-19 pandemic on mental health, studies like this one serve as important reminders of the unique mental health needs of young people. Supporting children and adolescents through proactive and targeted mental health services—especially during times of crisis—will be crucial to fostering resilience and well-being in future generations.
Adult ADHD has long been a subject of debate in the field of mental health, with previous estimates of its prevalence varying widely. To achieve a more precise understanding, an international team of researchers conducted a new umbrella review and meta-analysis, offering an updated estimate of adult ADHD rates worldwide.
This large-scale analysis combined five systematic reviews and meta-analyses, incorporating data from 57 unique primary studies. Altogether, the research synthesized findings from a pooled total of over 21 million participants. This comprehensive approach provided a more accurate estimate of the global prevalence of ADHD in adults.
The study concluded that the worldwide prevalence of adult ADHD is 3.1%, with a 95% confidence interval ranging from 2.6% to 3.6%. This estimate falls within the range of earlier reports but provides a more targeted understanding of the rate at which ADHD affects adults globally.
The researchers described this prevalence rate as “relatively high.” They noted that it is only slightly lower than the estimated prevalence of major mental health conditions like schizophrenia (4%) and major depressive disorder (5%)—disorders that have historically received significant attention and resources worldwide.
Moreover, the prevalence of adult ADHD is higher than that of several other well-known mental health conditions, including bipolar disorder (1%), as well as anxiety disorders such as PTSD (Post-Traumatic Stress Disorder), OCD (Obsessive-Compulsive Disorder), GAD (Generalized Anxiety Disorder), and panic disorders.
This updated estimate emphasizes that ADHD is a significant global mental health concern in adults, comparable to or exceeding the prevalence of other disorders that are often more widely recognized. These findings underscore the need for greater awareness, research, and treatment options for adult ADHD, which is still frequently misunderstood or overlooked in the broader discourse of mental health.
By providing a clearer picture of how prevalent ADHD is in adult populations around the world, this study contributes valuable data that could shape future research, policy, and clinical approaches.
Attention-Deficit/Hyperactivity Disorder (ADHD) remains a prevalent condition among children and adolescents in the United States. A recent analysis based on the National Health Interview Survey (NHIS), conducted by the National Center for Health Statistics at the CDC, provides an updated look at ADHD prevalence from 2018 to 2021. Here’s a closer look at what the data reveals.
The NHIS is an annual survey primarily conducted through face-to-face interviews in respondents’ homes. Telephone interviews are used as a substitute in cases where travel is impractical. For each family interviewed, one child aged 3-17 is randomly selected for the survey through a computer program. Over the four years studied (2018-2021), a total of 26,422 households with children or adolescents participated.
The analysis found that 9.5% of children and adolescents in the United States had been diagnosed with ADHD, based on reports from family members. However, the prevalence varied significantly with age:
The increase in ADHD diagnosis with age underscores the importance of monitoring children’s developmental needs as they progress through school and adolescence.
The survey revealed a notable difference in ADHD prevalence between genders, with 12.4% of males diagnosed compared to 6.6% of females—nearly a two-to-one gap. This aligns with previous research indicating that ADHD is more frequently diagnosed in boys than girls, though awareness of how ADHD presents differently across genders is growing.
Family income played a significant role in ADHD prevalence, particularly among lower-income groups:
This pattern suggests that socioeconomic factors might influence the diagnosis and management of ADHD, with lower-income families possibly experiencing greater barriers to early diagnosis or consistent treatment.
Geographic location also impacted ADHD rates. Prevalence was highest in the South (11.3%), followed by the Midwest (10%), the Northeast (9.1%), and significantly lower in the West (6.9%). These variations could reflect regional differences in healthcare access, diagnostic practices, or cultural attitudes towards ADHD.
Despite these variations in demographics, the overall prevalence of ADHD remained relatively stable across the study period from 2018 to 2021, showing no significant changes by year.
The findings from this updated analysis provide a clearer picture of ADHD’s prevalence across different demographic groups in the United States. They highlight the need for tailored approaches to diagnosis and care, taking into account factors like age, gender, income, and geographic location. With ADHD being a common condition affecting nearly 1 in 10 children, ongoing research and support for families are crucial to ensure that those with ADHD receive the care and resources they need.
This study reinforces the importance of awareness and early intervention, especially for families in underserved regions or those facing economic challenges. As clinicians and educators continue to support children with ADHD, understanding these demographic trends can help in creating more equitable access to diagnosis and treatment.
