When my colleagues and I wrote our "Primer" about ADHD, the topic of brain mechanisms was a top priority. Because so much has been written about the ADHD brain, it is difficult to summarize. Yet we did it with the eight pictures reproduced here in one figure.

A quick overview of this figure shows you the complexity of ADHD's pathophysiology. There is no single brain region or neural circuit that is affected.

Figures (a) and (b) show you the main regions implicated by structural and functional neuroimaging studies.

As (c) shows, these regions are united by neural networks rich in noradrenalin (aka, norepinephrine) and dopamine, two neurotransmitters whose activity is regulated by medications that treat ADHD.

Figure (d) describes two functional networks.

The executive control network is, perhaps, the best-described network in ADHD. This network regulates behavior by linking the dorsal striatum with the dorsolateral prefrontal cortex. This network is essential for inhibitory control, self-regulation, working memory, and attention.

The Corticocerebellar network is a well-known regulator of complex motor skills. Data also suggest it plays a role in the regulation of cognitive functions.

Figure (d) describes the Reward Networks of the brain that link the ventral striatum with the prefrontal cortex. This network regulates how we experience and value rewards and punishments. In addition to its involvement in ADHD, this network has also been implicated in substance use disorders, for which ADHD persons are at high risk.

Figures (f)(g) and (h) complete the puzzle with additional regions implicated in ADHD whose role is less well understood. One role for these regions is in the regulation of the Default Mode Network, which controls what the brain does when it is not focused on any specific task (e.g., daydreaming, mind wandering).

People differ in the degree to which they shift between the default mode network and networks like Reward or Executive Control, which are active when we engage the world. Recent data suggest that the brains of ADHD people may be in 'default mode' when they ought to be engaged in the world.

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.

There are several very effective drugs for ADHD, and those treatment guidelines from professional organizations view these drugs as the first line of treatment for people with ADHD. The only exception is for preschool children where medication is only the first line of treatment for severe ADHD; the guidelines recommend that other preschoolers with ADHD be treated with non-pharmacologic treatments, when available. Despite these guidelines, some parents and patients have been persuaded by the media or the Internet that ADHD drugs are dangerous and that non-drug alternative are as good or even better. Parents and patients may also be influenced by media reports that doctors overprescribe ADHD drugs or that these drugs have serious side effects. Such reports typically simplify and/or exaggerate results from the scientific literature. Thus, many patients and parents of ADHD children are seeking non-drug treatments for ADHD. What are these non-pharmacologic treatments and do they work? My next series of blogs will discuss each of these treatments in detail. Here I'll give an overview of my evidenced-based taxonomy of non-pharmacologic treatments for ADHD described in more detail in a book I recently edited (Faraone, S. V. &Antshel, K. M. (2014). ADHD: Non-Pharmacologic Interventions. Child Adolesc Psychiatry Clin N Am 23, xiii-xiv.). I use the term "evidence-based" in the strict sense applied by the Oxford Center for Evidenced Based Medicine (OCEBM; http://www.cebm.net/). Most of the non-drug treatments for ADHD fall into three categories: behavioral, dietary, and neurocognitive. Behavioral interventions include training parents to optimize methods of reward and punishment for their ADHD child, teaching ADHD children social skills, and helping teachers apply principles of behavior management in their classrooms. Cognitive behavior therapy is a method that teaches behavioral and cognitive skills to adolescent and adult ADHD patients. Dietary interventions include special diets that exclude food coloring or eliminate foods believed to cause ADHD symptoms. Other dietary interventions provide supplements such as iron, zinc, or omega-3 fatty acids.  The neurocognitive interventions typically use a computer-based learning setup to teach ADHD patients cognitive skills that will help reduce ADHD symptoms. There are two metrics to consider when thinking about the evidence base for these methods. The first is the quality of the evidence. For example, a study of 10 patients with no control group would be a low-quality study, but a study of 100 patients randomized to either a treatment or control group would be of high quality and the quality would be even higher if the people's rating patient outcomes did not know who was in each group. The second metric is the magnitude of the treatment effect. Does the treatment dramatically reduce ADHD symptoms, or does it have only a small effect? This metric is only available for high-quality studies that compare people treated with the method and people treated with a 'control' method that is not expected to affect ADHD. I used a statistical metric to quantify the magnitude of the effect. Zero means no effect, and larger numbers indicate better effects on treating ADHD symptoms. For comparison, the effect of stimulant drugs for ADHD is about 0.9, which is derived from a very strong evidence base.  The effects of dietary treatments are smaller, about 0.4 to 0.5, but because the quality of the evidence is not strong, these results are not certain and the studies of food color exclusions apply primarily to children who have high intakes of such colorants. In contrast to the dietary studies, the evidence base for behavioral treatments is excellent, but the effects of these treatments on ADHD symptoms are very small, less than 0.1.  Supplementation with omega-3 fatty acids also has a strong evidence base, but the magnitude of the effect is also small (0.1 to 0.2). The neurocognitive treatments have modest effects on ADHD symptoms (0.2 to 0.4) but their evidence base is weak. This review of non-drug treatments explains why ADHD drug treatments are usually used first. The evidence base is stronger, and they are more effective in reducing ADHD symptoms. There is, however, a role for some non-drug treatments. I'll be discussing that in subsequent blog posts. See more evidence-based information about ADHD at www.adhdinadults.com

Myth:  ADHD medications "anesthetize" ADHD children.
 The idea here is that the drug treatment of ADHD is no more than a chemical straightjacket intended to control a child's behavior to be less bothersome to parents and teachers. After all, everyone knows that if you shoot up a person with tranquilizers, they will calm down.

Fact:  ADHD medications are neither anesthetics nor tranquilizers.
The truth of the matter is that most ADHD medications are stimulants. They don't anesthetize the brain; they stimulate it. By speeding up the transmission of dopamine signals in the brain, ADHD medications improve brain functioning, which in turn leads to an increased ability to pay attention and control behavior.  The non-stimulant medications improve signaling by norepinephrine. They also improve the brain's ability to process signals. They are not sedatives or anesthetics. When taking their medication, ADHD patients can focus and control their behavior to be more effective in school, work, and relationships.  They are not "drugged" into submission.

Myth: ADHD medications cause drug and alcohol abuse
We know from many long-term studies of ADHD children that when they reach adolescence and adulthood, they are at high risk for alcohol and drug use disorders. Because of this fact, some media reports have implied that their drug use was caused by treatment of their ADHD with stimulant medications.

Fact: ADHD medications do not cause drug and alcohol abuse
Some ADHD medications indeed use the same chemicals that are found in street drugs, such as amphetamine.  But there is a very big difference between these medications and street drugs. When street drugs are injected or snorted, they can lead to addiction, but when they are taken in pill form as prescribed by a doctor, they do not cause addiction. When my colleagues and I examined the world literature on this topic, we found that rather than causing drug and alcohol abuse, stimulant medicine protected ADHD children from these problems later in life. One study from researchers at Harvard University and the Massachusetts General Hospital found that the drug treatment of ADHD reduced the risk for illicit drug use by84 a percent. These findings make intuitive sense. These medicines reduce the symptoms of the disorder that lead to illicit drug use. For example, an impulsive ADHD teenager who acts without thinking is much more likely to use drugs than an ADHD teen whose symptoms are controlled by medical drug treatment. After we published our study, other work appeared. Some of these studies did not agree that ADHD medications protected ADHD people from drug abuse, but they did not find that they caused drug abuse.

Myth:  Psychological or behavioral therapies should be tried before medication.  
Many people are cautious about taking medications, and that caution is even stronger when parents consider treatment options for their children.  Because medications can have side effects, shouldn't people with ADHD try to talk therapy before taking medicine?

Fact:  Treatment guidelines suggest that medication is the first-line treatment.
The problem with trying talk or behavior therapy before medication is that medication works much better.  For ADHD adults, one type of talk therapy(cognitive behavioral therapy) is recommended, but only when the patient is also taking medication.  The multimodal treatment of ADHD (MTA) study examined this issue in ADHD children from several academic medical centers in the United States. That study found that treating ADHD with medication was better than treating it with behavior therapy. Importantly, behavior therapy plus medication was no more effective than medication alone. That is why treatment guidelines from the American Academy of Pediatrics and the American Academy of Children and Adolescents recommend medicine as a first-line treatment for ADHD, except for preschool children. ADHD medications indeed have side effects, but these are usually mild and typically do not interfere with treatment.  And don't forget about the risks that a patient faces when they do not use medications for ADHD.  These untreated patients are at risk for worsening ADHD symptoms and complications.

Myth: Brain abnormalities of ADHD patients are caused by psychiatric medications
A large scientific literature shows that ADHD people have subtle problems with the structure and function of their brains.  Scientists believe that these problems are the cause of ADHD symptoms. Critics of ADHD claim that these brain problems are caused by the medications used to treat ADHD.  Who is right?

Fact: Brain abnormalities are found in never medicated ADHD patients.
Alan Zametkin, a scientist at the US National Institute of Mental Health, was the first to show brain abnormalities in ADHD patients who had never been treated for their ADHD.  He found that some parts of the brains of ADHD patients were underactive. His findings could not be due to medication because the patients had never been medicated. Since his study, many other researchers have used neuroimaging to examine the brains of ADHD patients. This work confirmed Dr. Zametkin’s observation of abnormal brain findings in unmediated patients. Reviews of the brain imaging literature have concluded that the brain abnormalities seen in ADHD cannot be attributed to ADHD medications.

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

Myth: ADHD is caused by poor parenting or teaching.
Parents and teachers are popular targets for those who misunderstand ADHD.  This myth posits that ADHD would not exist if parents and teachers were more effective at disciplining and teaching children.  From this perspective, ADHD is a failure of society, not a brain disease.

Fact: ADHD occurs when genes and toxic environments harm the brain.
Blaming parents and teachers for ADHD is wrong.  We know from research studies that many parents of ADHD children have normal parenting skills and even when we train parents to be better parents, ADHD does not disappear.  Many parents of ADHD children have an anon-ADHD child that they raised with the same discipline methods.  If bad parenting causes ADHD, all the children in the family should have ADHD. Equally important, decades of research studies have shown that genes and toxic environments cause ADHD by harming the brain.  I'm not saying that all parents and teachers are perfect.  Teaching parents and teachers, special methods for dealing with ADHD can help children with ADHD.  

Myth: Watching Television causes ADHD.
This myth hit the media in 2004 when a research group published a paper suggesting that toddlers who watched too much TV were at risk for attentional problems later in life.

Fact: The study was wrong.
Sometimes researchers get it wrong. But fortunately, science is self-correcting; if an incorrect result is published, subsequent studies will show that it is wrong. That's what happened with the ADHD television study.  After the first study made such a media splash, several other researchers did similar studies.  They found out that the original study had errors and that watching too much TV does not cause ADHD.  But, because the popular media did not pick up the later studies, the myth persists. I'm not recommending that toddlers watch a lot of television, but rest assured that, if they do, it will not cause ADHD.

Myth: Too much sugar causes ADHD.
This idea is based on common sense.  Many parents know that when their children and their friends have too much sugary food, they can get very active and out of control.

Fact: Sometimes, common sense is wrong.
As a parent, I thought there was some truth to the sugar myth.   But when a colleague, Dr. Wolraich, reviewed the world literature on the topic, he found that there have been many studies on the effect of sugar on children.  These studies show that sugar does not affect either the behavior or the thinking patterns of children.  Having too much sugar is bad for other reasons, but it does not cause ADHD.

I recently came across a paper from Tom Brown that adds to the growing scientific literature about smart people with ADHD. Dr. Brown's study measured executive functions in 157 ADHD adults with an intelligence quotient (IQ) in the top 9 percent of the population. The executive functions of the brain regulate cognitive processes in a manner that allows for the effective planning and execution of behaviors.

We know from many studies that both children and ADHD have deficits in executive functions, which impair their ability to manage time and keep themselves organized. Dr. Brown extends that literature by showing that three out of four ADHD adults with high IQ scores were significantly impaired on tests of executive functioning. They had problems in many areas: working memory, processing speed, and auditory-verbal working memory relative.

The lesson from this literature is clear. Smart people can have ADHD. Their high IQs will help them do better than the average person with ADHD, but they may not achieve their potential without appropriate diagnosis and treatment.

Raising children is not easy. I should know.

As a clinical psychologist, I've helped parents learn the skills they need to be better parents. And my experience raising three children confirmed my clinical experience.

Parenting is a tough job under the best of circumstances, but it is even harder if the parent has ADHD.

For example, an effective parent establishes rules and enforces them systematically. This requires attention to detail, self-control, and good organizational skills. Given these requirements, it is easy to see how ADHD symptoms interfere with parenting. These observations have led some of my colleagues to test the theory that treating ADHD adults with medication would improve their parenting skills. I know about two studies that tested this idea.

In 2008, Dr. Chronis-Toscano and colleagues published a study using a sustained-release form of methylphenidate for mothers with ADHD. As expected, the medication decreased their symptoms of inattention and hyperactivity/impulsivity. The medication also reduced the mother's use of inconsistent discipline and corporal punishment and improved their monitoring and supervision of their children.

In a 2014 study, Waxmonsky and colleagues observed ADHD adults and their children in a laboratory setting once when the adults were off medication and once when they were on medication. They used the same sustained-release form of amphetamine for all the patients. As expected, the medications reduced ADHD symptoms in the parents. This laboratory study is especially informative because the researchers made objective ratings of parent-child interactions, rather than relying on the parents' reports of those interactions. Twenty parents completed the study. The medication led to less negative talk and commands and more praise by parents. It also reduced negative and inappropriate behaviors in their children.

Both studies suggest that treating ADHD adults with medication will improve their parenting skills. That is good news. But they also found that not all parenting behaviors improved. That makes sense. Parenting is a skill that must be learned. Because ADHD interferes with learning, parents with the disorder need time to learn these skills. Medication can eliminate some of the worst behaviors, but doctors should also provide adjunct behavioral or cognitive-behavioral therapies that could help ADHD parents learn parenting skills and achieve their full potential as parents.

Research on ADHD has extensively explored various aspects of the condition, yet surprisingly little attention has been devoted to its impact on romantic relationships. Despite over 25,000 articles on ADHD listed in PubMed, only a small number examine topics such as love, sex, and relationship dynamics.

One study by Brunner and colleagues analyzed ADHD symptoms and romantic relationship quality in 189 college students. The findings indicated that students with high levels of hyperactivity-impulsivity and inattentiveness reported lower relationship quality compared to peers with fewer ADHD symptoms. Similarly, a study of 497 college students revealed that ADHD symptoms were linked to the use of maladaptive coping strategies in relationships, resulting in reduced romantic satisfaction.

In research involving young adults, ADHD symptoms were associated with greater negativity and reduced positivity during conflict resolution tasks within romantic partnerships. Higher levels of ADHD symptoms were predictive of lower relationship satisfaction. However, couples where the ADHD partner displayed only inattentive symptoms experienced fewer relational challenges, suggesting that the severity and type of symptoms significantly influence outcomes.

Regarding sexual behavior, studies highlight distinct patterns among individuals with ADHD. Adolescents with ADHD, regardless of gender, report nearly double the number of lifetime sexual partners compared to their non-ADHD peers. These findings align with research by Barkley and colleagues, who observed that ADHD predicted earlier sexual activity and parenthood. Similarly, Flory and colleagues, in a retrospective study, found that childhood ADHD was associated with earlier sexual initiation, more sexual partners, casual relationships, and unintended pregnancies.

A broader study of over 1,000 adults found that ADHD was associated with less stability in romantic relationships, difficulty providing emotional support, higher rates of sexual dysfunction, and increased divorce rates.

Although the body of research on ADHD and romantic relationships is relatively small, it consistently highlights the significant impact of ADHD on love, sex, and relational dynamics, often presenting unique challenges for those affected.

‍

In the popular media, ADHD has sometimes been portrayed as a minor condition or not a disorder at all. It is easy to find websites claiming that ADHD is an invention of the medical profession and that the symptoms used to diagnose the disorder are simply normal behaviors that have been "medicalized". These claims are wrong. They miss the main point of any psychiatric diagnostic process, which is to identify people who experience distress or disability due to a set of well-defined symptoms. So, does ADHD cause serious distress and disability? It is a serious psychiatric condition? To illustrate the strong evidence base for the "Yes" answer to that question, my colleagues and I constructed this infographic for our "Primer" about ADHD,http://rdcu.be/gYyV.It describes the many ways in which the symptoms of ADHD impact and impair the lives of children, adolescents, and adults with the disorder. We divided these 'impacts' into four categories: other disorders (both psychiatric and medical), psychological dysfunction, academic and occupational failure, social disability, and risky behaviors. Let's start with other health problems. We know from many studies that have followed ADHD children into adolescence and adulthood that having the disorder puts patients at risk for several psychiatric disorders, addictions, criminality, learning disabilities, and speech/language disorders. ADHD even increases the risk for-psychiatric diseases such as obesity, hypertension, and diabetes. Perhaps most worrisome is that people with ADHD have a small increased risk for premature death. This increased risk is due in part to their having other psychiatric and medical conditions and also to their risky behaviors which, as research documents, lead to accidents and traumatic brain injuries. In the category of psychological dysfunction,' we highlighted emotional dysregulation, which makes ADHD people quick to anger or fail to tame extreme emotions. Other serious psychological issues are low self-esteem and increased thoughts of suicide, which lead to more suicide attempts than for people without ADHD. This increased risk for suicide is small, but it is real. A more prevalent impact of ADHD is the broad category of social disability, which includes marital discord, poor parenting, legal problems, arrests, and incarceration. This typically starts in youth with poor social adjustment and conflict with parents, siblings, and friends. Another common impact of ADHD is on academic and vocational pursuits. ADHD youth are at risk for underachievement in school, repeating grades, and dropping out. As adults, they are more likely to be unemployed or underemployed, which leads to them having lower incomes than expected for their level of school achievement. So, don't believe anyone who claims that ADHD is not a disorder or is only a mild one. To be sure, there is a wide range of impairments among people with ADHD but, in the absence of treatment, they are at risk for adverse outcomes. Fortunately, the medications that treat ADHD have been documented to reduce this risk, which is why they are typically the first-line treatment for most people with ADHD.
