Are there Positive Aspects to ADHD?

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.

Northern Finnish Population Study Finds ADHD Slashes Higher Education Attainment, Comorbidity of ADHD + ODD much worse

Background:

Although ADHD typically begins in childhood, its symptoms frequently continue into adulthood, and it is widely acknowledged as having a lifelong prevalence for most persons with ADHD. 

ADHD symptoms are linked to poor academic performance, mainly due to cognitive issues like compromised working memory. These symptoms lead to long-term negative academic outcomes and difficulty in achieving higher educational degrees. 

Oppositional Defiant Disorder (ODD) often co-occurs with ADHD. In community samples, it appears in about 50–60% of those with ADHD. ODD symptoms include an angry or irritable mood, vindictiveness toward others, and argumentative or defiant behavior that lasts more than 6 months and significantly disrupts daily life.  

Since ODD tends to co-occur with ADHD, research on pure ODD groups without ADHD is limited, especially in community samples. This longitudinal study aimed to examine the impact of ADHD and ODD symptoms in adolescence on academic performance at age 16 and educational attainment by age 32. 

Study:

Finland, like other Nordic countries, has a single-payer health insurance system that includes virtually all residents. A Finnish research team used the Northern Finnish Birth Cohort to include all 9,432 children born from July 1, 1985, through June 30, 1986, and followed since then. 

ADHD symptoms were measured at age 16 using the Strengths and Weaknesses of ADHD symptoms and Normal-behaviors (SWAN) scale. 

Symptoms of ODD were screened using a 7-point rating scale similar to the SWAN scale, based on eight DSM-IV-TR criteria: “Control temper”, “Avoid arguing with adults”, “Follow adult requests or rules”, “Avoid deliberately annoying others”, “Assume responsibility for mistakes or misbehaviour”, “Ignore annoyances from others”, “Control anger and resentment”, and “Control spitefulness and vindictiveness.” 

Higher education attainments were determined at age 32. 

Results:

After adjusting for the educational attainments of the parents of the subjects, family type, and psychiatric disorders other than ADHD or ODD, males with ADHD symptoms at age 16 had a quarter, and females a little over a third, of the higher education attainments of peers without ADHD symptoms at age 32.  

With the same adjustments, males with ODD symptoms alone had two-thirds, and females 80%, of the higher education attainments of peers without ODD, but neither outcome was statistically significant. 

However, all participants with combined ADHD and ODD symptoms at age 16 had roughly one-fifth of the higher education attainments of peers without such symptoms upon reaching age 32. 

Interpretation: 

The team concluded, “The findings that emerged from this large longitudinal birth cohort study showed that the co-occurrence of ODD and ADHD symptoms in adolescence predicted the greatest deficits of all in educational attainment in adulthood.” 

This study highlights the significant, long-lasting impact that co-occurring ADHD and ODD symptoms can have on educational outcomes well into adulthood. It underscores the importance of addressing both disorders together during adolescence to help improve future academic success.

U.S. Nationwide Study Finds Down Syndrome Associated with 70% Greater Odds of ADHD

The Background:

Down syndrome (DS) is a genetic disorder resulting from an extra copy of chromosome 21. It is associated with intellectual disability. 

Three to five thousand children are born with Down syndrome each year. They have higher risks for conditions like hypothyroidism, sleep apnea, epilepsy, sensory issues, infections, and autoimmune diseases. Research on ADHD in patients with Down syndrome has been inconclusive. 

The Study:

The National Health Interview Survey (NHIS) is a household survey conducted by the National Center for Health Statistics at the CDC. 

Due to the low prevalence of Down syndrome, a Chinese research team used NHIS records from 1997 to 2018 to analyze data from 214,300 children aged 3 to 17, to obtain a sufficiently large and nationally representative sample to investigate any potential association with ADHD. 

DS and ADHD were identified by asking, “Has a doctor or health professional ever diagnosed your child with Down syndrome, Attention Deficit Hyperactivity Disorder (ADHD), or Attention Deficit Disorder (ADD)?” 

After adjusting for age, sex, and race/ethnicity, plus family highest education level, family income-to-poverty ratio, and geographic region, children and adolescents with Down syndrome had 70% greater odds of also having ADHD than children and adolescents without Down syndrome. There were no significant differences between males and females. 

The Take-Away:

The team concluded, “in a nationwide population-based study of U.S. children, we found that a Down syndrome diagnosis was associated with a higher prevalence of ASD and ADHD. Our findings highlight the necessity of conducting early and routine screenings for ASD and ADHD in children with Down syndrome within clinical settings to improve the effectiveness of interventions.”

Meta-analysis Explores Link Between ADHD and Homelessness Among Children and Adolescents

An estimated 150 million children and adolescents live on the streets worldwide. In the U.S., roughly 1.5 million experience homelessness annually. Homelessness increases the risk of health issues, violence, early pregnancy, substance use, vaccine-preventable diseases, mental disorders, suicidal behavior, and early death. 

Rates of anxiety, major depression, conduct disorders, and post-traumatic stress disorder are higher among school-age homeless children compared to their housed peers.  

However, there has been limited attention to ADHD, leading a French research team to conduct a systematic review and meta-analysis of its prevalence among homeless children and adolescents.  

The inclusion criteria required that participants be homeless, under 19 years of age at baseline, and have ADHD identified through a screening tool, self-report, or clinical assessment. 

Results:

Meta-analysis of 13 studies with a combined total of 2,878 individuals found indications of ADHD in almost one in four homeless children and adolescents. There was no sign of publication bias, but considerable variation in estimates across studies. 

The team found a dose-response effect. Meta-analysis of six studies with 1,334 participants under 12 years old reported 13% with indications of ADHD. Meta-analysis of five studies encompassing 991 individuals, 12 through 18 years old, found an ADHD rate of 43%. The ADHD rate among adolescents was 3.3 times greater than among children

There were no significant differences among countries. 

Moreover, limiting the meta-analysis to the seven studies with 1,538 participants that relied on clinical ADHD diagnoses, the gold standard,  resulted in an ADHD prevalence of 23%

The team concluded, “The review of 13 studies revealed that ADHD is common in homeless children and adolescents, suggesting that homelessness may contribute to the development or exacerbation of ADHD symptoms. Conversely, ADHD with other comorbidities may increase the likelihood of homelessness. Reintegrating these children and adolescents into care systems and ensuring access to public health interventions tailored for homeless families and youth is imperative for breaking the cycle of homelessness and improving long-term trajectories.” 

In other words, this review not only confirmed a strong link between homelessness and ADHD in children and youth, but also suggested a complex, cyclical relationship. Providing tailored health care and support for these vulnerable groups is crucial to interrupt this cycle and help improve their future outcomes.
