You might have heard ADHD risks being over-diagnosed. Here's why that's not the case
One hot topic is whether ADHD is being over-diagnosed.
- One hot topic is whether ADHD is being over-diagnosed.
- Public hearings for the Australian Senate’s inquiry into “consistent, timely and best practice assessment” of ADHD and support services begin today.
What is ADHD?
- Worldwide, around 5% of children and 2.5% of adults meet the full diagnostic criteria for ADHD.
- Importantly, just having hyperactive, impulsive and inattentive symptoms is not sufficient to qualify for a diagnosis of ADHD.
- To meet current diagnostic criteria, these symptoms must have a negative effect on a person’s “social, school, or work functioning”.
Overdiagnosis or misdiagnosis?
- Overdiagnosis is a concept first developed in cancer screening to highlight situations where “the diagnosis of disease that would never cause symptoms or death during a given patient’s lifetime”.
- This definition has since been employed in many other areas of medicine, as well as analyses of health systems.
- When defined in this way, overdiagnosis is distinct from the concept of misdiagnosis, which is where an incorrect diagnosis has been made.
Different definitions
- One 2021 article on ADHD and overdiagnosis defined it as occurring when the “net effect of the diagnosis is unfavourable”.
- There are many reasons an ADHD diagnosis may be “unfavourable”, for some individuals.
- Some people experience negative side effects from ADHD treatments, or experience stigma as a result of ADHD diagnosis.
- But when you think about ADHD as not just having certain symptoms, but as having harmful outcomes, this might be expected.
Not a medical condition
- Some concerns about ADHD overdiagnosis appear to be based on a belief ADHD should not be considered as a medical condition.
- From this perspective, the concerns would again be more accurately and transparently phrased in terms of misdiagnosis.
- Even in the United States where rates of ADHD diagnosis exceed 5%, they still fall short of the estimated epidemiological prevalence.
Where to from here?
- So GPs and others – like Mental Health Nurse Practitioners – may well play an important role in assessing and managing ADHD.
- There would clearly need to be extensive training and support and also changes in the way assessments are funded.
