Why more adults are seeking answers
Millions of adults live with undiagnosed ADHD or autism. Growing awareness has led more people to ask: "Is this why things have always felt harder for me?" But getting a clinical diagnosis means months of waiting and hundreds of euros — often just to be told what you already suspect. We built this tool to give you clarity before that investment.

Built on validated clinical science
This is not a quiz pulled from the internet. Every question in this screening is derived from the same peer-reviewed, clinically validated instruments that psychiatrists and neuropsychologists use in formal diagnostic evaluations. Our scoring thresholds are calibrated against published normative data from these instruments. This is what makes our screening meaningful rather than speculative.
ASRS v1.1 (WHO)
The Adult ADHD Self-Report Scale, developed by the World Health Organization. The most widely used ADHD screening instrument worldwide, with 18 items mapping directly to DSM-5 diagnostic criteria. Validated across dozens of studies with known sensitivity and specificity rates.
CAARS (Conners')
The Conners' Adult ADHD Rating Scales, the gold-standard clinical assessment tool for adult ADHD. Provides separate Inattention, Hyperactivity, and Impulsivity subscales with T-score norms stratified by age and gender. Used in clinical practice and research globally.
WURS (Wender Utah)
The Wender Utah Rating Scale assesses retrospective childhood ADHD symptoms in adults. Critical because DSM-5 requires evidence of symptoms before age 12. Our childhood history section is built on WURS methodology to evaluate this diagnostic criterion.
AQ (Baron-Cohen)
The Autism-Spectrum Quotient, developed at Cambridge University's Autism Research Centre. Measures autistic traits across 5 domains: social skill, attention switching, attention to detail, communication, and imagination. Validated threshold of 32+ captures ~80% of autism cases.
RAADS-R (Ritvo)
The Ritvo Autism Asperger Diagnostic Scale-Revised, specifically designed for diagnosing autism in adults. 80 items across 4 domains with 97% sensitivity and 100% specificity in validation studies. Uniquely distinguishes lifelong traits from acquired behaviours.
DSM-5 & ICD-11
Our item domains map directly to the Diagnostic and Statistical Manual (5th edition) and International Classification of Diseases (11th revision) diagnostic criteria. These are the two classification systems used worldwide for formal clinical diagnosis of ADHD and autism.
By combining elements from all these instruments into a single comprehensive screening, we provide broader coverage than any single tool alone. A clinician using just the ASRS would miss autism. One using just the AQ would miss ADHD. Our screening covers both, with the clinical depth that lets you make an informed decision about whether formal evaluation is worth your time and money.
Instant results, zero cost
Complete 246 scientifically designed questions covering 8 clinical domains — 4 for ADS/ADHD and 4 for Autism Spectrum. Your responses are scored instantly against thresholds derived from the same validated instruments clinicians use: ASRS, CAARS, WURS, AQ, and RAADS-R.
You'll see your scores per domain, visual charts, and a clear indication of whether your profile falls in the typical, elevated, or clinically significant range. All free, anonymous, no registration.
Everything you need to decide if this is worth exploring further.
Go deeper with an AI-powered clinical report
Numbers only tell part of the story. Our Deep Report uses advanced AI to analyze your individual response patterns — not just totals, but which specific items you scored highest on and what they mean together clinically.
The report explains each domain in plain language with references to DSM-5 and ICD-11 criteria, identifies symptom clusters in your answers, evaluates potential comorbidity between ADHD and autism, and gives you concrete recommendations on whether to seek evaluation — and what type of professional to look for.
Like having a preliminary conversation with a specialist — for €9.99 instead of €800.
A professional document you can bring to your clinician
Your report is structured like a formal clinical screening document: executive summary, domain-by-domain analysis, overall assessment, and personalized recommendations. Export it as a PDF and bring it to your appointment — many clinicians appreciate having structured preliminary data as a starting point.
The report is stored securely for 10 days, accessible only with your email. After that, it's permanently deleted. No accounts, no tracking, no data sold.
Your data, your decision, your pace.
