Everything You Need to Know About ADHD

You've heard all sorts of misinformation about Attention-Deficit/Hyperactivity Disorder(ADHD), whether from friends, the internet, or uninformed press articles:

"ADHD is not real."

"Pharmaceutical companies invented ADHD to make money."

"I'm just a little ADD."

"Natural solutions are the best for ADHD treatment."

ADHD symptoms were first described in the late 1700s, primarily among hyperactive boys. It was described variously over 200 years as "fidgeting," "defects of moral control," "hyperkinetic reaction," "minimal brain damage" and eventually ADD (Attention Deficit Disorder) in the 1980s and ADHD today.

Because the natural tendency toward hyperactivity decreased with age, ADHD was originally thought to be a developmental disorder that disappeared in mid-to-late adolescence. When medicines were developed and used in ADHD treatment for young boys, physicians stopped prescribing them around mid-adolescence, because it was presumed the condition had been remediated. They were wrong. We know now that ADHD persists into adulthood for about two-thirds of ADHD youth.

ADHD was not widely recognized in girls until the mid-1990s when it became clear that girls with ADHD were less disruptive than boys with ADHD and were not being appropriately diagnosed. Girls with ADHD show less of the physical hyperactivity of boys, but suffer from "dreaminess," "lack of focus" and "lack of follow-through."

It was also in the 1990s that ADHD' pervasive comorbidity with depression, anxiety, mood, and autism spectrum disorders was established. At the same time, researchers were beginning to describe deficits in executive functioning and emotional dysregulation that became targets of substantial research in the 21st century.

Even with the 1990s recognition that ADHD is a lifetime disorder, equally present (in different forms) in both men and women, medical schools and continuing medical education courses (required for realizing sure of health professionals) have only begun to teach the most up-to-date evidence-based knowledge to the medical community. There still is much misinformation and a lack of knowledge among primary care professionals and the public.

ADHD Throughout the Lifespan
Most cases of ADHD start in Otero before the child is born. As a fetus, the future ADHD person carries versions of genes that increase the risk for the disorder. At the same time, they are exposed to toxic environments. These genetic and environmental risks change the developing brain, setting the foundation for the future emergence of ADHD.

In preschool, early signs of ADHD are seen in emotional lability, hyperactivity, disinhibited behavior and speech, and language and coordination problems. The full-blown ADHD syndrome typically occurs in early childhood, but can be delayed until adolescence. In some cases, the future ADHD person is temporarily protected from the emergence of ADHD due to factors such as high intelligence or especially supportive family and/or school environments. But, as the challenges of life increase, this social, emotional, and intellectual scaffolding is no longer sufficient to control the emergence of disabling ADHD symptoms.

Throughout childhood and adolescence, the emergence and persistence of the disorder are regulated by additional environmental risk factors such as family chaos, as well as the age-dependent expression of risk genes that exert different effects at different stages of development. During adolescence, most cases of ADHD persist and by the teenage years, many youths with ADHD have onset with a mood, anxiety, or substance use disorder. Indeed, parents and clinicians need to monitor ADHD youth for early signs of these disorders. Prompt treatment can prevent years of distress and disability.

By adulthood, the number of comorbid conditions increases, including obesity, which likely impacts future medical outcomes. Emerging data shows people with ADHD to be at increased risk for hypertension and diabetes. ADHD adults tend to be very inattentive but show fewer symptoms of hyperactivity and impulsivity. They remain at risk for substance abuse, low self-esteem, injuries due to accidents, occupational failure, and social disability, especially if they are not treated for the disorder.

Seven Important Concepts About ADHD


There are approximately 10 million U.S. adults with ADHD, 9 million of whom are undiagnosed. But with diligent research by the medical profession, we have learned seven important concepts about ADHD:
1.    ADHD has been documented worldwide in 5% of the population.
2.    Sixty-seven percent of ADHD children grow into ADHD adults and seniors. ADHD is heritable, runs in families, and is impacted by the physical environment and familial lifestyle.
3.    In youth, rates of ADHD are higher in males than females as males, but these rates even out by adulthood.
4.    ADHD coexists and is often masked by several other disorders: anxiety, depression, spectrum bipolar and autism disorder, substance abuse, alcoholism, obesity, risky behaviors, disorganized lives, working memory deficits, and significant executive dysfunctions that affect personal, social, and work success.
5.    ADHD medications(stimulants and non-stimulants) are the most effective treatments for ADHD symptoms. Psychological support/training designed for ADHD, and lifestyle modifications, are important adjuncts to medicine.
6.    ADHD costs the U.S. economy more than $100 million annually in lost productivity, accidents, hospitalizations with comorbidities, and family and professional support for ADHD patients.
7.    ADHD is diagnosable and safely treatable in trained primary care practices.

How do you know if you or someone you love has ADHD? Evaluate your life against the seven concepts above. Then get screened and diagnosed by a health care professional. The diagnosis of ADHD should be done only by a licensed clinician who has been trained in ADHD. That clinician should have one goal in mind: to plan a safe and effective course of evidence-based treatment.

When diagnosing adults, it is also useful to collect information from a significant other, which can be a parent for young adults or a spouse for older adults. But when such individuals are not available, diagnosing ADHD based on the patient's self-report is valid. Just remember that personal, work, and family lives are improved with treatment. Research and technology related to ADHD improve all the time.

ADHD in Adults is a great resource for anyone interested in learning more about ADHD, with evidence-based information and education for both healthcare professionals and the public. The website also features a new ADHD screener for predicting the presence of ADHD in adults.

Meta-analysis Reports Executive Function Gains from Exercise Interventions for ADHD

Background:

The development of ADHD is strongly associated with functional impairments in the prefrontal cortex, particularly the dorsolateral prefrontal cortex, which plays a key role in maintaining attention and controlling impulses. Moreover, imbalances in neurotransmitters like dopamine and norepinephrine are widely regarded as major neurobiological factors contributing to ADHD. 

Executive functions are a group of higher-order cognitive skills that guide thoughts and actions toward goals. “Executive function” refers to three main components: inhibitory control, working memory, and cognitive flexibility. Inhibitory control helps curb impulsive actions to stay on track. Working memory allows temporary storage and manipulation of information for complex tasks. Cognitive flexibility enables switching attention and strategies in varied or demanding situations. 

Research shows that about 89% of children with ADHD have specific executive function impairments. These difficulties in attention, self-control, and working memory often result in academic and social issues. Without timely intervention, these issues can lead to emotional disorders like depression, anxiety, and irritability, further affecting both physical health and social development. 

Currently, primary treatments for executive function deficits in school-aged children with ADHD include medication and behavioral or psychological therapies, such as Cognitive Behavioral Therapy (CBT). While stimulant medications do improve executive function, not all patients are able to tolerate these medications. Behavioral interventions like neurofeedback provide customized care but show variable effectiveness and require specialized resources, making them hard to sustain. Safer, more practical, and long-lasting treatment options are urgently needed. 

Exercise interventions are increasingly recognized as a safe, effective way to improve executive function in children with ADHD. However, systematic studies on school-aged children remain limited.  

Moreover, there are two main scoring methods for assessing executive function: positive scoring (higher values mean better performance, such as accuracy) and reverse scoring (lower values mean better performance, such as reaction time). These different methods can affect how results are interpreted and compared across studies. This meta-analysis explored how different measurement and scoring methods might influence results, addressing important gaps in the research. 

The Study:

Only randomized controlled trials (RCTs) involving school-aged children (6–13 years old) diagnosed with ADHD by DSM-IV, DSM-5, ICD-10, ICD-11, or the SNAP-IV scale were included. Studies were excluded if the experimental group received non-exercise interventions or exercise combined with other interventions. 

Cognitive Flexibility 

Using positive scoring, exercise interventions were associated with a narrowly non-significant small effect size improvement relative to controls (eight RCTs, 268 children). Using reverse scoring, however, they were associated with a medium effect size improvement (eleven RCTs, 452 children). Variation (heterogeneity) in individual RCT outcomes was moderate, with no sign of publication bias in both instances. 

Inhibitory Control 

Using positive scoring, exercise interventions were associated with a medium effect size improvement relative to controls (ten RCTs, 421 children). Using reverse scoring, there was an association with a medium effect size improvement (eight RCTs, 265 children). Heterogeneity was moderate with no sign of publication bias in either case. 

Working Memory 

Using positive scoring, exercise interventions were associated with a medium effect size improvement relative to controls (six RCTs, 321 children). Using reverse scoring, the exercise was associated with a medium effect size improvement (five RCTs, 143 children). Heterogeneity was low with no indication of publication bias in both instances. 

Conclusion:

The team concluded, “Exercise interventions can effectively improve inhibitory control and working memory in school-aged children with ADHD, regardless of whether positive or reverse scoring methods are applied. However, the effects of exercise on cognitive flexibility appear to be limited, with significant improvements observed only under reverse scoring. Moreover, the effects of exercise interventions on inhibitory control, working memory, and cognitive flexibility vary across different measurement paradigms and scoring methods, indicating the importance of considering these methodological differences when interpreting results.” 

Although this work is intriguing, it does not show that exercise significantly improves the symptoms of ADHD in children. This means that exercise, although beneficial for many reasons, should not be viewed as a replacement for evidence-based treatments for the disorder.

Here’s What the Wall Street Journal Got Wrong about the Medication Treatment of ADHD Patients: A Lesson in Science Media Literacy

A recent Wall Street Journal article raised alarms by concluding that many children who start medication for ADHD will later end up on several psychiatric drugs. It’s an emotional topic that will make many parents, teachers, and even doctors worry: “Are we putting kids on a conveyor belt of medications?”

The article seeks to shine a light on the use of more than one psychiatric medication for children with ADHD.   My biggest worry about the article is that it presents itself as a scientific study because they analyzed a database.  It is not a scientific study.  It is a journalistic investigation that does not meet the standards of a scientific report..

The WJS brings attention to several issues that parents and prescribers should think about. It documents that some kids with ADHD are on more than one psychiatric medication, and some are receiving drugs like antipsychotics, which have serious side effects.  Is that appropriate? Access to good therapy, careful evaluation, and follow-up care can be lacking, especially for low-income families.  Can that be improved?  On that level, the article is doing something valuable: it’s shining a spotlight on potential problems.

It is, of course, fine for a journalist to raise questions, but it is not OK for them to pretend that they’ve done a scientific investigation that proves anything. Journalism pretending to be science is both bad science and bad journalism.

Journalism vs. Science: Why Peer Review Matters

Journalists can get big datasets, hire data journalists, and present numbers that look scientific.  But consider the differences between Journalism and Science. These types of articles are usually checked by editors and fact-checkers. Their main goals are:

 Is this fact basically correct?

 Are we being fair?

 Are we avoiding legal problems?

But editors are not qualified to evaluate scientific data analysis methods.  Scientific reports are evaluated by experts who are not part of the project.  They ask tough questions like: 

Exactly how did you define ADHD? 

How did you handle missing data? 

Did you address confounding? 

Did you confuse correlation with causation?

If the authors of the study cannot address these and other technical issues, the paper is rejected.

The WSJ article has the veneer of science but lacks its methodology.  

Correlation vs. Causation: A Classic Trap

The article’s storyline goes something like this:  A kid starts ADHD medication.  She has additional problems or side effects caused by the ADHD medications.   Because of that, the prescriber adds more drugs.  That leads to the patient being put on several drugs.  Although it is true that some ADHD youth are on multiple drugs, the WSJ is wrong to conclude that the medications for ADHD cause this to occur.  That simply confuses correlation with causation, which only the most naïve scientist would do.

In science, this problem is called confounding. It means other factors (like how severe or complex a child’s condition is) explain the results, not just the thing we’re focused on (medication for ADHD). 

The WSJ analyzed a database of prescriptions.  They did not survey the prescribers who made the prescriptions of the patients who received them.  So they cannot conclude that ADHD medication caused the later prescriptions, or that the later medications were unnecessary or inappropriate. 

Other explanations are very likely.   It has been well documented that youth with ADHD are at high risk for developing other disorders such as anxiety, depression,  and substance use.  The kids in the WSJ database might have developed these disorders and needed several medications.  A peer-reviewed article in a scientific journal would be expected to adjust for other diagnoses. If that is not possible, as it is in the case of the WSJ’s database, a journal would not allow the author to make strong conclusions about cause-and-effect.

Powerful Stories Don’t Always Mean Typical Stories

The article includes emotional accounts of children who seemed harmed by being put on multiple psychiatric drugs.  Strong, emotional stories can make rare events feel common.  They also frighten parents and patients, which might lead some to decline appropriate care. 

These stories matter. They remind us that each data point is a real person.  But these stories are the weakest form of data.  They can raise important questions and lead scientists to design definitive studies, but we cannot use them to draw conclusions about the experiences of other patients.  These stories serve as a warning about the importance of finding a qualified provider,  not as against the use of multiple medications.  That decision should be made by the parent or adult patient based on an informed discussion with the prescriber.

Many children and adults with ADHD benefit from multiple medications. The WSJ does not tell those stories, which creates an unbalanced and misleading presentation.  

Newspapers frequently publish stories that send the message:  “Beware!  Doctors are practicing medicine in a way that will harm you and your family.”   They then use case studies to prove their point.  The title of the article is, itself, emotional clickbait designed to get more readers and advertising revenue.  Don’t be confused by such journalistic trickery.

What Should We Conclude?

Here’s a balanced way to read the article.  It is true that some patients are prescribed more than one medication for mental health problems.  But the article does not tell us whether this prescribing practice is or is not warranted for most patients.  I agree that the use of antipsychotic medications needs careful justification and close monitoring.  I also agree that patients on multiple medications should be monitored closely to see if some of the medications can be eliminated.  Many prescribers do exactly that, but the WSJ did not tell their stories.  

It is not appropriate to conclude that ADHD medications typically cause combined pharmacotherapy or to suggest that combined pharmacotherapy is usually bad. The data presented by the WSJ does not adequately address these concerns.  It does not prove that medications for ADHD cause dangerous medication cascades.

We have to remember that even when a journalist analyzes data, that is not the same as a peer-reviewed scientific study. Journalism pretending to be science is both bad science and bad journalism.

Oppositional Defiant Disorder, Autism, and ADHD: New Research Examines the Connection

Oppositional Defiant Disorder (ODD)—a pattern of chronic irritability, anger, arguing, or defiance—is one of the most challenging behavioral conditions families and clinicians face. 

A new study involving 2,400 children ages 3–17 offers one of the clearest pictures yet. Using parent-reported data from the Pediatric Behavior Scale, researchers compared how often ODD appears in Autism spectrum disorder (ASD), ADHD-Combined presentation (ADHD-C), ADHD-Inattentive presentation (ADHD-I), and those with both ASD and ADHD.

Results

ADHD-Combined + ODD: The Highest-Risk Group

Children with ADHD-Combined presentation show both hyperactivity/impulsivity and inattention.  They had the highest ODD rates of any single diagnosis: 53% of kids with ADHD-Combined met criteria for ODD.

But when autism was added to ADHD-Combined, the prevalence jumped to 62%. This group also had the highest overall ODD scores, suggesting more severe or more impairing symptoms. 

This synergy matters: while autism alone increases ODD risk, the presence of ADHD-Combined is what pushes prevalence into the majority range. Other groups showed lower, but still significant, rates of ODD:

  • Autism + ADHD-Inattentive: 28%
  • Autism Only: 24%
  • ADHD-Inattentive Only: 14%

These findings echo what clinicians often see: children with inattentive ADHD, while struggling significantly with attention and learning, tend to show fewer behavioral conflict patterns than those with hyperactive/impulsive symptoms.

It is important to note that ODD is considered to have two main components. Across all diagnostic groups, ODD consistently broke down into these two components: either Irritable/Angry (emotion-based) or Oppositional/Defiant (behavior-based). But the balance between these components differed depending on diagnosis. Notably, Autism + ADHD-Combined showed higher levels of the irritable/angry component than ADHD-Combined alone. The oppositional/defiant component did not differ much between groups. This suggests that autism elevates the emotional side of ODD more than the behavioral side, which is important for clinicians to note before tailoring interventions.

Understanding ADHD , ASD, & Comorbidity:

The study notes that autism, ADHD, and ODD often cluster together, with 55–90% comorbidity in some combinations.

As the authors explain, The high co-occurrence of ADHD-Combined in autism (80% in our study) largely explains the high prevalence of ODD in autism.” 

Clinical Implications: Why This Study Matters

The researchers point to a straightforward recommendation: clinicians shouldn’t evaluate these conditions in isolation. A child referred for autism concerns might also be struggling with ADHD. A child referred for ADHD might have undiagnosed ODD. And ignoring one disorder can undermine treatment for the others.

Evidence-based interventions (behavioral therapy, parent training, school supports, and/or medication) can reduce symptoms across all three diagnoses while improving long-term outcomes, including overall quality of life.
