The Growing Debate Around ADHD
ADHD, or attention deficit hyperactivity disorder, has become a topic of significant media attention in recent years. Whether through unfiltered TikTok influencers or formal public awareness campaigns, it’s hard to miss the growing conversation around this condition. People with ADHD often struggle with being distractible, forgetful, and impulsive, and may also have high energy levels. While stimulant medication is commonly used to manage symptoms, it was once thought to primarily affect children, especially boys. However, it is now recognized in adults as well, regardless of gender.
There are diverse perspectives on ADHD. For many parents of affected children, it is a condition that remains under-recognized and requires better resources. NHS waiting times for assessments can be over two years, which adds to the frustration. On the other hand, skeptics like Lincoln psychiatrist Dr Sami Timimi argue that ADHD is an example of “overmedicalisation.” This concept suggests that modern medicine unnecessarily labels people with quirky personalities, leading them to take life-long psychoactive drugs.
Robert F Kennedy (RFK), the US health chief, recently called for an inquiry into the rising numbers of children taking ADHD medications as part of his Make America Healthy Again campaign. So, where does the truth lie? What is it like to find out you have ADHD as an adult? And what could explain the increase in cases?
What’s Happening to the Numbers?
ADHD is currently in the news due to a recent study examining whether the number of cases is indeed increasing. The findings, published in the Journal of Affective Disorders, showed no significant rise in the number of cases in the US, Canada, and Sweden between 2020 and 2024. This lack of recent growth made some headlines, but previous studies indicated an increase in ADHD diagnoses in the UK from 2000 to 2018. By 2018, the highest rates were among boys aged 10 to 16, with 3.5 per cent diagnosed and 2.4 per cent on medication. In 2000, those numbers were 1.4 per cent and 0.6 per cent respectively.
Professor Phillip Shaw, director of the King’s Maudsley Partnership for Children and Young People in London, stated, “It seems likely that clinical diagnosis rates in the UK continue to increase – but we need research to see exactly the size of this.”
The Story of an Adult Diagnosis
The UK study found that while teenage boys have the highest rate of ADHD overall, the biggest relative increase in medication use in the past two decades was in adults. Stimulant medicines not only help schoolchildren but can also assist adults in focusing at work and in daily life.
Caroline Williams, who was diagnosed with ADHD at 48, shared her experience. She had suspected for a long time but felt it wasn’t something that applied to adults, especially women. “Everyone goes to the supermarket and forgets what’s on the list, but I can go with a list, cross things off, and still not have a key ingredient,” she said.

After a six-month wait, Williams was assessed through an NHS pathway, which confirmed her suspicions. Her doctor suggested trying standard ADHD medication. Initially, she used it only when needed, but she found herself more productive when taking it daily. Without the medication, she would struggle to start her day’s tasks. “You know logically that these things are important, but they’re all at the top jostling for position, and there’s no way of knowing where to start,” she explained.
Better Recognition and Broader Definitions
The growing number of ADHD diagnoses might seem alarming, but Professor Shaw noted that the 3.5 per cent rate in teenage boys is still likely an underestimate. Other studies using behavioral tests on large groups of children, whether diagnosed or not, suggest the true figure is about 5 per cent of children.
Years of increased awareness and reduced stigma have led to more families seeking diagnoses and necessary medication. The long waiting lists for assessments may simply reflect more people coming forward. “The most likely explanation is that we’re playing catch-up,” said Professor Shaw.
Another possibility is that doctors have become more inclined to diagnose ADHD than in the past. Unlike conditions with clear biological markers, ADHD lacks a definitive blood test or brain scan. Instead, doctors use checklists to determine if symptoms meet certain severity levels based on age, which can be subjective.
Professor Edmund Sonuga-Barke, a developmental psychologist at King’s College London, explained that ADHD is not a single condition but represents one end of a spectrum involving impulsivity and inattention. “This means the margin between ADHD and non-ADHD becomes more arbitrary,” he said.
Cultural Differences and Social Media
Cultural differences between countries could explain why ADHD diagnosis rates vary globally. For instance, the rate for under-18s in Sweden is 3.2 per cent, while in the US, it is 10 per cent. This variation may also explain why ADHD isn’t necessarily a lifelong condition. Recent research found that a quarter of children diagnosed with ADHD were no longer classified as such within five years, while another quarter saw the diagnosis come and go.
A common belief is that the rise of fast-paced social media content, like TikTok videos, is shortening attention spans and contributing to the rise in ADHD. While some studies have found correlations between more social media use and ADHD-like symptoms, Professor Shaw emphasized that this doesn’t prove causation. “We don’t know if social media is driving some symptoms of inattention, or if kids who are a bit distractible are the ones going online and multitasking,” he said.
Lockdown Disruption and Future Research
While long-term trends are evident, the impact of the pandemic on ADHD rates cannot be ignored. “Kids had a marked disruption to their learning environment for about two or three years,” said Professor Shaw. However, the latest study did not find significant changes in diagnosis rates during the pandemic in Sweden, Canada, and the US.
Dr Alex Martin, a psychologist at King’s College London, noted, “There was some evidence for fluctuations across Covid, that bounced back to expected rates prior to the pandemic, but those fluctuations were not statistically significant.” He added that more research is needed to understand how ADHD rates have changed in the UK recently.
Personal Impact and Final Thoughts
Despite the ongoing debate, Caroline Williams found her diagnosis to be a source of validation. “It was validation that I wasn’t just making this up and I wasn’t just lazy. There was something actually making it more difficult for me than it should be,” she said. This realization has significantly improved her quality of life.
