Why Does It Feel Like Everybody Is Getting Diagnosed With ADHD and Autism These Days?

It seems like every person surrounding us is being diagnosed with Attention-Deficit/Hyperactivity Disorder (ADHD) and Autism Spectrum Disorder (ASD) these days. This dramatic increase in diagnosis of neurodevelopmental disorders isn't just a perception; it has some backing in the form of research and epidemiological findings from nations such as the United States and the world over, though causes are multifarious and multi-dimensional.

To begin with, growing numbers of diagnoses for ADHD and autism are largely determined by increasing awareness within society. With more mainstream discussions of mental illness, the stigmas surrounding these conditions have diminished. Greater numbers of parents, teachers, adults, and even doctors are now better at observing and understanding symptoms that, ten or twenty years ago, tended to get ignored or misdiagnosed.

For instance, the definition of ADHD has expanded to encompass not just the hyperactive-impulsive presentation but also that based on inattention, particularly in females, who may not have fit the classic hyperactive stereotype in earlier sets of diagnostic criteria. The consequence is that individuals who perhaps would have remained undiagnosed in earlier times are now diagnosed correctly and appropriately, enhancing their outcomes through access to effective interventions.

Secondly, diagnostic reporting and criteria for ADHD and autism have changed significantly over time. A study in Denmark found that 60% of the increase in the number of children diagnosed with autism between 1980 and 1991 was due to changes in diagnostic criteria and increased reporting awareness. In the USA, population-level studies indicated that the majority of the rise in reported autism incidence could be accounted for by a change in classification of those previously classified under "intellectual disability" to "autism" as assessment criteria and labelling standards improved. In effect, far more individuals are being classified as belonging to the wider diagnostic categories of ADHD or ASD than previously, although the underlying incidence of either of these neurodevelopmental profiles is not shifting so radically.

Increased access to healthcare services is another driver of rising diagnosis rates. Broader government and insurance coverage across much of the world has allowed families and individuals to more affordably pursue evaluation. Concurrently, there's been a broad movement toward early screening programs, especially in states such as California, which have some of the highest rates of autism diagnosis because of aggressive assessment policies. The byproduct is an increase in diagnosis rates, but also an increased likelihood of timely and proper intervention.

Environmental and societal forces, most recently the COVID-19 pandemic have contributed further. Several studies and clinical observations highlight the fact that the pandemic disruption of daily routine made attention, concentration, and organizational issues even more evident in children and adults. Online schooling enabled parents to see more clearly the struggles of their children with attention and routine, leading to more requests for evaluation.

At the same time, the lack of external structure while working or studying from home resulted in many adults understanding for the first time that their long-term concentration problems met the ADHD profile. The trends here are interesting: over 8.7 million American adults were diagnosed with ADHD by 2023, doubling the prevalence observed twenty years before.

Social media has made it simpler for individuals to learn about autism and ADHD. Instagram and TikTok, for instance, are full of posts and videos where individuals explain symptoms and their own experiences. Upon viewing, the public may get to understand that they identify with the behaviour or issues in question, hence leading more individuals to attend professionals for a diagnosis. But doctors warn not to trust everything you see on the internet. Sometimes, individuals believe they have autism or ADHD based on social media, but a diagnosis should always be made by a qualified professional, not from video-watching or post-reading.

Overall, the increase in ADHD and autism diagnoses is not merely a fad. It is evidence of real advances: physicians are better acquainted with these conditions, the diagnostic criteria are broader, individuals speak more freely about mental illness, and the internet assists in providing wider awareness. The point is to ensure this increased awareness translates into the correct support through professional evaluation rather than self-diagnosis.
