Is there a positive side to having ADHD?

If you are searching for positive aspects of ADHD on the web, you will find a lot of websites claiming all kinds of positive sides to having ADHD, such as being more creative, able to hyperfocus, or being more spontaneous. However, if you try to back up this information by scientific evidence, you will be disappointed. Up to now, research in ADHD has almost exclusively focused on cognitive and behavioral deficits in people with the disorder. With ADHD being a disabling disorder, this may not be surprising on the one side. On the other, however, scientific research in several other target groups, shows there is indeed evidence pointing in the direction of a positive side of neurodevelopmental disorders and traits associated with ADHD. Take for example creativity: for disorders such as bipolar disorder and schizophrenia, strong links with creativity have been observed in large samples1, and these disorders overlap phenotypically (e.g. through impulsivity) and genetically with ADHD. Also, creative people are often risk-takers and novelty seekers, as are people with ADHD20. From genetic studies, we can also derive suggestive evidence for a possible link between ADHD and creativity. groenebrainlampwebsiteMHThe dopamine receptor D4 gene (DRD4), also sometimes called the ‘adventure gene’, is a candidate ADHD risk gene identified by meta-analysis2 but has also been associated with increased divergent thinking3. Further evidence comes from brain imaging studies, showing brain regions involved in creative thinking, temporal and frontal lobe4, 5, to overlap regions implicated in ADHD (Hoogman et al. in prep & e.g.6).

What is already known about creativity and ADHD?

Creativity tests can be divided into tasks that measure divergent thinking (such as the alternative or unusual uses task and the Torrance test of creative thinking), and tasks that measure convergent thinking (e.g. the remote associations task). Also, questionnaires that relate to creative achievement are used to acquire information about ones creative abilities (e.g. the creative achievement questionnaire). A handful of studies has linked ADHD (symptoms) with creative performance. These studies had a maximum sample size of 90. Healey and colleagues showed that among creative children, ADHD symptoms were higher than in less creative children7. Another study, by White and Shah, found increased divergent thinking in ADHD college students as compared with non-ADHD college students8. And also higher creative achievement was found in ADHD9. Additional studies did not find a relationship between ADHD (symptoms) and creativity. For example, in a study by Aliabadi and colleagues, there was no difference on a figural Torrance test of creative thinking, and patients performed worse on fluency and flexibility11.

Another way of looking at potential links between creativity and ADHD is by using possible proxies of creativity, e.g. having a creative profession. Investigating the Swedish population registries in this way did not result in evidence for more creative professions among people with ADHD than among others12. This might be due to the categorization of creative professions (writers, painter, dancers, scientists), as this might be too broad. Also, people with ADHD are often unemployed, which would lead to an underrepresentation of people with ADHD in these studies.

So (what now)…?

Patients consistently claim a link between creativity in ADHD, but this link has not been the subject of large-scaled studies that are indispensable to define such a potential link scientifically. The one large, proxy-based study of creativity and ADHD, did not find a link between both12. Should we stop there? I don’t think so. Following the demand of patients to know more about creativity in ADHD as well as the promising findings of several small-sampled studies, I think that it does deserve our attention to not only focus on the deficits of ADHD. Finding answers on this subject might reduce stigma in ADHD, as we know from previous work that more knowledge about a disorder will create understanding and lessen prejudice13. In addition, it also has the potential to help patients cope with their disorder and support them in making choices education- and career-wise.

Therefore, we are currently making a first attempt to study creativity in our adult ADHD clinical study (IMPACT2-NL) by testing creative performance on divergent and convergent thinking tasks and by administering a creative achievement questionnaire. To be able to relate creative performance to the known cognitive deficits of ADHD, we will also assess those. In addition, we will also collect brain imaging and genetic data to gain knowledge on the underlying neural mechanisms. We are also working on reaching out to other ongoing studies to add creativity tasks to their testing batteries.

It goes without saying that ADHD is a debilitating disorder. However, we feel that if there is a chance that some positive sides of ADHD exist, they deserve to be studied.
