Why Are More People Being Diagnosed with ADHD and Autism Now?

It can feel like ADHD and Autism are suddenly everywhere.
More people are talking about it online. More people are seeking assessments. More parents are wondering whether their child might be neurodivergent. More workplaces and schools are being asked to think about accommodations.
So naturally, more people are asking whether ADHD and Autism actually increasing, or are we just recognising them more?
The answer is probably a bit nuanced, as most useful answers are. Diagnosis numbers have definitely increased. In Australia, the APS has reported that more than one million Australians are estimated to have ADHD, and AIHW data shows ADHD medication dispensing has also risen substantially in recent years, with more than 4.6 million ADHD-related prescriptions dispensed to just under 600,000 patients in 2023–24.
Autism recognition has also increased. The ABS reported 290,900 Autistic Australians in 2022, up from 205,200 in 2018, while Aspect has suggested Autism prevalence may be at least 1 in 40 Australians.
But this does not mean ADHD and Autism suddenly appeared.
A big part of the story is that we are finally getting better at recognising people who were always there.
ADHD and Autism Have Always Existed
ADHD and Autism are not new.
Neurodivergent people have always existed. What has changed is how we understand, describe, and identify neurodivergence. For a long time, public understanding of ADHD and Autism was shaped by very narrow stereotypes. ADHD was often imagined as a young boy who could not sit still. Autism was often imagined through a very limited picture of social difficulty, visible distress, or obvious support needs.
That meant many people were missed. Some were labelled as shy, sensitive, gifted but lazy, too much, not trying hard enough, or just anxious. A lot of people were not “suddenly neurodivergent”. They were neurodivergent all along, but nobody had the right language for it at the time.
And honestly, for many adults, receiving a diagnosis later in life is less about discovering something new and more about finally having the words for something they have been trying to explain for years.
We Understand Neurodivergence Differently Now
One of the biggest reasons diagnoses have increased is that our understanding of ADHD and Autism has changed. Additionally, diagnostic criteria have also changed.
The DSM-5, released in 2013, made several important updates. It broadened how ADHD could be recognised across the lifespan, including in adolescents and adults. It also brought several previously separate Autism-related diagnoses under the umbrella of Autism Spectrum Disorder. One particularly important change was that ADHD and autism could now be diagnosed together. Before the DSM-5, these diagnoses were treated as mutually exclusive, meaning someone could not be diagnosed with both.
We also understand more about masking, internalised presentations, sensory differences, and how neurodivergence can show up differently across gender, culture, age, personality, and environment. For example, someone may have spent years appearing organised on the outside while privately feeling overwhelmed, exhausted, or constantly behind. Someone else may have done well academically while quietly struggling with sensory overload, social confusion, or burnout.
Being “high functioning” was often just another way of saying:“Your distress was not obvious enough for people to notice.”
More people are being diagnosed now because we are slowly getting better at seeing the people who were previously overlooked.
Social Media and Online Communities Have Increased Awareness
Social media often gets blamed for the rise in ADHD and Autism diagnoses.
And yes, there is misinformation online. Not every thirty-second video can capture the complexity of a neurodevelopmental profile. We have all seen the occasional post that makes a very human experience sound like a diagnostic criterion.
But social media has also done something important. It has given people access to lived experience. For many adults, seeing someone describe masking, time blindness, sensory overload, rejection sensitivity, autistic burnout, or executive dysfunction can be the first moment they think: “Wait. Other people experience this too?”
Online communities have also helped reduce stigma. People are sharing their stories, advocating for themselves, and challenging old stereotypes about what ADHD and Autism “look like”.
Social media is not a substitute for assessment. But it can be a doorway into self-understanding.
More Awareness Means More Access
As awareness grows, more people are seeking support.
Parents are more likely to notice when their child is struggling in ways that might reflect ADHD or Autism. Teachers are more familiar with neurodivergent learning differences. Workplaces are slowly becoming more aware of reasonable adjustments. Clinicians are increasingly recognising presentations that were historically missed.
This does not mean access is easy.
Assessment can still be costly. Waitlists can be long. Some people still face dismissal, stigma, or confusion when they raise the possibility of ADHD or Autism. But compared with previous generations, more people now have access to information, language, and pathways to assessment.
And when people are identified earlier, or even just understood more accurately, they have a better chance of getting support that actually helps.
Diagnosis Isn’t Trendy
There is a common narrative online that ADHD and Autism are becoming trendy, and we think it's worth discussing that. Most people do not seek an assessment casually.
People usually start exploring ADHD or Autism because something has been hard for a long time. Maybe they have been burnt out for years. Maybe they have tried therapy for anxiety or depression and felt like something still did not quite fit. Maybe school, work, relationships, parenting, or daily life has felt harder than it seems to for other people.
A diagnosis can bring relief, but it can also bring grief, confusion, anger, or a lot of rethinking. People may look back and realise how much they were masking. They may feel sadness for the younger version of themselves who was misunderstood. They may need time to work out what support looks like now.
That is not a trend.
That is self-understanding.
A Diagnosis is Not the End Goal
A diagnosis can be incredibly helpful.
It can provide validation, access to supports, and a clearer understanding of your needs. For some people, it can be life-changing.
But diagnosis is not the end of the story.
The next part is often asking: what does this mean for me?
At Very Helpful Chats, our assessments are designed to support that bigger picture. We offer ADHD and Autism assessments, as well as a range of neurodivergent assessments for people who want to better understand things like executive functioning, burnout, personality, workplace needs, or educational accommodations.
The goal is not just to give you a label and send you on your way. Our goal is to help you understand yourself more clearly, with practical, neuro-affirming information you can actually use.
If you are exploring whether ADHD or Autism might explain your experiences, or if you have already been diagnosed and are wondering what comes next, you are welcome to learn more about our assessment options in your own time.
Because more people are not suddenly becoming neurodivergent.
More people are finally being recognised.
