What are we to make of adults who exhibit the diagnostic criteria for ADHD, but are nevertheless high-functioning and successful? A trio of British investigators has just published six case studies that explore this question. It would have been better for them to have conducted a much larger, controlled research study but, in the absence of such data in the area, these case studies are intriguing and may help guide more informative research.
The authors recruited six successful men between the ages of 30 and 65 from a National Health Service tertiary service in London. Four were in long-term relationships, with children. All had good jobs.
In open-ended taped interviews of up to an hour in length, each was asked three questions:
1. What do you think are the advantages and disadvantages of having ADHD?
2. Please describe a time when you felt that your ADHD helped you to achieve something?
3. What aspects of your ADHD would you miss if it went away?
Hyper-focus in ADHD is generally considered a deficit, inset-shifting, and task-switching. But the authors report that participants associated it with productivity. One said, “I think the energy that the ADHD brain seems to have....it’s unfocused, quite scattered, chaotic and a bit random...but give that brain something that you can tune into, and it’s your interest, then all that random stuff just goes boom... I get this incredible intense concentration and that’s great for work.”
Participants also saw advantages in divergent thinking, with one stating, “I’m an artist.... a creative type... a Bohemian.... you are most likely to be a creative person if you are a divergent thinker....and not convergent... I am very creative and that’s through and through... I’m a fine art graduate, a musician, a published poet, an entrepreneur, a performer.”
All the participants reported being seen as nonconformists. Depending on a viewpoint, that can be seen as either detrimental or advantageous.
Impulsivity is a core symptom of ADHD. Participants however related it to bravery, and more specifically adventurousness, spontaneity, and thrill-seeking. One said, “thrill-seeking is an ADHD thing... I can list in my life have done white water rafting, bungee jumping, hand-glider pilot … I have done a lot in my life and achieved a lot and experienced a lot... Furthermore, I would see a lot of that as being quite positive, and a lot of that is ADHD drive.”
Another common theme was high energy and “spirit.” One participant said, “I’ve got all this energy.... a lot of energy... whatever it's to do with... nature/nurture/spiritual stuff.”
These testimonials are useful as a check on the usual narrative of impairment. ADHD does not predestine all it afflicts to an unfulfilling life. Many, often assisted by medication, still lead exciting, successful, rewarding lives. Yet, we must be cautious in concluding that these individuals were successful because of their ADHD. It is possible, even likely, that they had other strengths such as high intelligence that compensated for their ADHD symptoms. We can not know from this report if their lives had been even more fulfilling or successful in the absence of ADHD. See, for example, my blog about highly intelligent people with ADHD: https://www.linkedin.com/pulse/20141126141502-65669938-smart-people-can-have-adhd-too/.
While the authors concede that “generalizing the findings of this study is not easy to do,” they inexplicably “also argue that the positive aspects we found are relevant to other adults with ADHD regardless of sample size, age, gender or ethnicity.” It is not possible to draw such a definitive conclusion without a much larger sample.
On a hopeful note, they conclude, “This is a study that reaches out to people with lived experience of ADHD: service users, patients, family members, carers, partners, to say that not all symptoms of ADHD are maleficent. Recovery, high functionality, and flourishing with ADHD are possible. Too often people with lived experience hear about ADHD deficits, functional impairments, and associations with substance misuse, criminality, or other disadvantages on almost every level of life (school, work, relationships). … This study affirms the positive human qualities, assets, and attributes in ADHD that can promote and sustain high functioning and flourishing.” I fully endorse the idea that those with ADHD can have wonderful lives, especially if they receive appropriate treatment, both medical and psychological.

The focus on children and adolescents with ADHD often revolves around behavioral issues and academic difficulties, but the social struggles are real. Around 60% of youth with ADHD experience meaningful difficulties in social skills, reading social cues, and forming reciprocal relationships with peers. Over time, these struggles can raise the risk of anxiety and depression.
Medication remains the primary treatment for ADHD, with stimulants like methylphenidate (Ritalin) being the most commonly prescribed. While effective at reducing core symptoms such as inattention and impulsivity, medication has not been shown to improve social behavior or peer relationships.
The Background:
Exercise has recently emerged as a promising adjunctive therapy. A newly published meta-analysis examined whether structured physical activity can specifically improve social functioning in young people with ADHD. It builds on a previous review from 2015, addressing gaps that earlier work left open: social outcomes were rarely treated as a primary focus, and no prior analysis had systematically compared exercise types or asked how much exercise is actually needed to see benefits.
The Study:
The analysis included 13 randomized controlled trials involving 703 participants aged 6 to 18, all clinically diagnosed with ADHD. Only exercise programs lasting at least four weeks were considered. Studies that combined exercise with other therapies, such as psychotherapy, were excluded to isolate exercise's specific effects.
The researchers used a technique called network meta-analysis, which allows different interventions to be compared against one another even when they haven't been tested head-to-head, alongside dose-response modeling to identify how much exercise produces the greatest benefit.
Results:
The most striking results came from closed-skill exercise: across four studies involving 92 participants, it was associated with a very large reduction in social dysfunction. Open-skill exercise, by contrast, showed no measurable improvement across four studies with 91 participants. Multicomponent exercise (the group combining elements of both open- and closed-skill) reported large gains in two smaller studies with 33 participants.
Mind-body exercise showed a moderate benefit across three studies involving 44 participants.
The dose-response analysis offered a practically useful finding: 30 to 60 minutes of moderate-intensity exercise per day appeared to produce the best outcomes, with a minimum of roughly 15 to 30 minutes daily needed to achieve any meaningful benefit.
The Take-Away:
The results are encouraging but should be interpreted carefully. The number of studies in each category was small (two to three studies each), and sample sizes were modest, meaning the findings may not hold up as more evidence accumulates. The absence of publication bias is reassuring, as is the use of rigorous methodology, but this remains an early-stage evidence base. Larger, well-designed trials are needed before firm clinical recommendations can be made.
For now, the findings position structured physical activity (particularly closed-skill and multicomponent exercise) as a plausible complement to existing ADHD treatment, specifically targeting the social difficulties that medication tends not to address. The practical dose guidance is a useful starting point: around half an hour of moderate daily exercise as a minimum, with an hour as the apparent sweet spot. As low-risk additions to a treatment plan go, that’s a relatively accessible bar for most families to consider alongside professional guidance.
Exercise has attracted growing attention as an intervention for ADHD. As a potential treatment option for ADHD, it is, of course, highly appealing because it can be low- to no-cost, widely accessible, and free of the side effects that can accompany medication. From previous studies, we know that certain types of exercise may be more effective than others, but do we actually know enough for clinicians to prescribe physical activity as a treatment for ADHD?
The First Study: Effects on Core ADHD Symptoms
Despite encouraging findings in individual studies, researchers have lacked clear guidance on which types of exercise work best, at what intensity, and for how long. A meta-analysis by Chen et al. set out to address this by pooling data from 20 randomized controlled trials (RCTs) involving 841 children and adolescents aged 4–18, all of which compared exercise interventions against non-exercising control groups.
The results were cautiously optimistic. Across standardized symptom scales, exercise produced a small improvement in ADHD symptoms overall. Objective cognitive tests showed a moderate improvement. Emotional and behavioral outcomes, however, showed no significant change.
To understand what was driving differences between studies, the researchers broke results down by exercise type. Therapeutic and alternative exercises (targeted movements and specific techniques such as those prescribed by physical therapists) were associated with moderate symptom improvements. Mind-body practices (such as yoga or tai chi) showed small-to-moderate gains. Conventional aerobic exercise yielded smaller effects, while skill-based competitive sports showed no measurable benefit. Notably, the variability between individual studies remained high throughout, meaning these categories should be interpreted with some caution.
Results:
The authors recommend that clinicians and parents consider incorporating therapeutic or alternative exercise sessions twice a week, each lasting 60–90 minutes, as a supplemental strategy alongside existing ADHD treatment. They stop short of calling this definitive, noting that future research should clarify how exercise produces its effects and how it might best be combined with medication or behavioral therapy.
The Second Study: Effects on Inhibitory Control
A second meta-analysis, by Zhang et al., zoomed in on a specific and particularly relevant cognitive challenge in ADHD: inhibitory control. Inhibitory control refers to the ability to suppress impulsive responses and tune out irrelevant distractions. This capacity underlies much of the restlessness, interrupting, and difficulty staying on task that characterize the condition.
This analysis drew on 34 studies with over 1,300 participants spanning all age groups, making it broader in scope than the Chen et al. review. Overall, exercise was associated with a moderate improvement in inhibitory control. When the analysis was restricted to RCTs alone, this finding held up. When studies with a high risk of bias were excluded, however, the effect size dropped to small-to-moderate.
One notable null result: three studies that used EEG to measure brain activity during inhibitory tasks found no significant effects on the neural signatures most closely tied to this process. This suggests exercise may influence behavior without necessarily changing the underlying brain mechanisms researchers expected, or that current methods aren't yet sensitive enough to detect such changes.
The dosing question produced some of the more practically useful findings. Single exercise sessions yielded only borderline small improvements. Sustained exercise programs, by contrast, showed moderate improvements, and programs with sessions three times per week produced large gains and had the strongest effect between the two meta-analyses. Exercise intensity and total program duration, perhaps interestingly, were not significant factors.
Results:
The authors are measured in their conclusions: exercise shows a real but modest benefit for inhibitory control, and frequency appears to matter more than intensity. They caution against overstating the case for exercise as treatment for ADHD overall, as it did not significantly affect hyperactivity or impulsivity as standalone outcomes, and its neural effects remain unclear.
The Broader Picture :
Ultimately, these two meta-analyses support exercise as a meaningful supplemental intervention for ADHD, particularly for attention and cognitive control, while urging realistic expectations. Neither suggests exercise should replace established treatments. Both are limited by high variability across the underlying studies, and both call for better-designed research to sharpen the guidance available to clinicians and families.
Boredom is more than just feeling restless or under-stimulated. It’s a negative emotional state that arises when activities feel meaningless or dull and, for those with ADHD, this negative emotional state might be markedly more intense. Researchers increasingly view boredom as functional: an internal signal pushing people to seek more rewarding and meaningful experiences. But for some, that signal becomes chronic and overwhelming.
People who are highly prone to boredom face a range of psychological and behavioral consequences, including anxiety, depression, difficulty identifying their own emotions (alexithymia), impulsivity, and physical complaints. These struggles often surface in harmful behaviors: overeating, substance use, compulsive internet use, and gambling.
For people with ADHD, boredom can cross into genuine distress. Many describe it as “torture” or “an itchy coat you can’t scratch”, language that conveys not mild discomfort but an urgent, almost unbearable need to escape. This makes sense given that ADHD involves core difficulties with attention, arousal regulation, and motivation, all of which make sustained engagement harder and boredom far more likely.
The Study:
A recent meta-analysis of 18 studies involving more than 22,000 participants confirmed a moderately strong and consistent positive association (an overall effect size of r = 0.40) between ADHD and self-reported boredom. All but one study found significant results, and there was no evidence of publication bias.
“While the relationship between ADHD and boredom may seem obvious,” the authors state, “this has paradoxically led to the phenomenon being understudied.”
Despite how significant this connection appears to be, the researchers noted it has attracted surprisingly little scientific attention; a gap they attribute to a widespread assumption that boredom in ADHD is simply a byproduct of inattention or impulsivity, and therefore not worth studying on its own terms. They push back on that view, arguing that boredom may be a more fundamental part of the ADHD experience: a bridge between atypical brain function and the behavioral, emotional, and cognitive difficulties that shape long-term outcomes.
The Take-Away:
Ultimately, addressing the profound boredom experienced by individuals with ADHD requires a multifaceted approach that goes beyond simply treating inattention. Researchers emphasize the need for rigorous studies to determine if stimulant medications actively reduce this intense boredom by repairing underlying brain mechanisms, rather than just as a side effect of improved focus. Beyond medication, tailored psychological therapies may offer promise; psychoeducation can help individuals reframe boredom as a biological signal rather than a personal failure or character flaw.
Additionally, another approach suggests that rather than solely focusing on treating the individual, systemic issues must be addressed, such as the effects of low-stimulation environments. For example, prioritizing a better "person-environment fit" through smaller class sizes, flexible academic pacing, and/or offering highly stimulating, novel tasks, schools and workplaces can offer meaningful relief from the chronic distress of ADHD-related boredom.
