Learn where you sit on the ADHD and Autism spectrum
Neurodivergent Test
You've always sensed your brain works differently — but without a diagnosis, it's hard to know what you're actually dealing with. This free assessment gives you a clearer picture in just a couple of minutes, so you can stop guessing and start understanding.
A free assessment
No waiting lists. No referrals. No jargon. Just 18 straightforward questions that give you an honest, indicative score across two areas — ADHD traits and Autism traits — so you finally have something concrete to work with.
Your ADHD likelihood score
You’ll receive a score that indicates how strongly your responses align with common ADHD traits — things like attention regulation, impulsivity, and time blindness. This isn’t a label; it’s a starting point for understanding why certain things have always felt harder for you than they seem to for everyone else.
Your Autism likelihood score
You’ll also get a score reflecting how closely your responses align with autistic traits — such as sensory sensitivity, social processing differences, and the energy it takes to navigate everyday situations. Many people find this is the first time they’ve had words for experiences they’ve carried silently for years.
A brief interpretation
Your scores don’t exist in a vacuum — you’ll get a plain-English summary of what they suggest and what the range of results typically looks like. Think of it as context, not a verdict.
Suggested next steps
Depending on where your scores land, you’ll be pointed toward the most relevant resource or support — whether that’s further reading, a conversation with Nick, or simply knowing you’re in the right place.

What research shows
You're not imagining it — and you're far from alone. The research on neurodivergence in adults tells a story that the mainstream rarely talks about: late identification, years of misdiagnosis, and a healthcare system struggling to keep pace with demand.
Here's what the data actually shows.
1 in 7 people in the UK are neurodivergent
Estimates suggest that around 15% of the UK population are neurodivergent in some way, including ADHD, autism, dyslexia, dyspraxia, and related conditions. Despite this prevalence, the majority of adults living with ADHD or autism today were never identified as children — meaning they’ve spent years developing workarounds for challenges they never had a name for, often at significant cost to their mental health and self-esteem.
Average NHS wait for an adult ADHD assessment is now 5+ years
A 2023 investigation by the BBC found that waiting times for adult ADHD assessments on the NHS had ballooned to between 5 and 13 years in some regions. Demand has increased dramatically — referrals have risen by over 400% in some areas in the last decade — while NHS capacity has not kept pace. For many adults, this means living in limbo: knowing something is different about how their brain works, but having no formal recognition, no support, and no answers.
Autism in adults is still significantly underdiagnosed
Research consistently shows that autistic women, girls, and non-binary individuals are diagnosed on average several years later than autistic men — largely because diagnostic criteria were historically developed based on studies of young boys. Masking, the learned behaviour of suppressing or camouflaging autistic traits to fit in socially, makes identification harder and is strongly linked to anxiety, depression, and burnout. Many adults seeking an assessment today have spent a lifetime being told they’re “too sensitive,” “too intense,” or “just anxious.”
Most adults with ADHD aren't diagnosed until their 30s, 40s, or later
The majority of adults currently receiving an ADHD diagnosis were not identified as children. For many, the diagnosis comes only after a crisis point — job loss, relationship breakdown, a period of severe mental health difficulty — or after a child in the family receives a diagnosis and a parent recognises themselves in the description. Studies suggest that undiagnosed ADHD significantly increases the risk of anxiety, depression, substance misuse, and employment difficulties, making early self-awareness genuinely life-changing.
The right support changes outcomes
Research shows that neurodivergent adults face disproportionately high rates of mental health difficulties — not because of their neurodivergence itself, but because of the sustained effort of navigating a world not designed for them. However, studies into ACT-based interventions show meaningful improvements in psychological flexibility, quality of life, and wellbeing for neurodivergent adults. Understanding your profile is the first step toward getting support that actually fits how your brain works.
