AuDHD: What It Means and What an AuDHD Test Can Tell You
AuDHD is an informal, community term for being both autistic and ADHD. It isn't a diagnosis on its own, and there's no single validated AuDHD test. Online quizzes can help you notice patterns. Only a full assessment can show whether you meet criteria for autism, ADHD or both. In Malaysia, psychiatrists and clinical psychologists carry out these assessments.
In short:
The word: AuDHD means autistic and ADHD. It's a community term, not a diagnosis.
Both at once: since DSM-5 in 2013, clinicians can diagnose autism and ADHD together.
How common: reviews put ADHD at roughly 28% to 70% of autistic people.
The test: online quizzes screen at best. Assessment uses interviews, your life history and people who know you.
At Ripple: Ripple doesn't diagnose autism or ADHD. An RM 50 screening helps you plan a next step. Adult therapy is with a team that works with neurodiversity.

What does AuDHD mean?
AuDHD is shorthand for being autistic and having ADHD (attention deficit hyperactivity disorder). Autistic ADHD adults use it, and so do some researchers. One 2026 study describes a combined autism and ADHD diagnosis as "not formally represented in diagnostic systems".
The word belongs to a wider idea called neurodiversity, which emerged in the late 1990s. It treats differences in how brains work as part of human variety. People whose brains work differently from what's considered typical often call themselves neurodivergent.
A note on words. A UK study of the autism community found "autistic" was widely endorsed by autistic adults. It also found no single term suited everyone, and some people prefer "person with autism". This article says "autistic people". If other words fit you better, use them.
Can you be autistic and have ADHD?
Yes. Older diagnostic manuals treated the two as mutually exclusive. That changed with DSM-5 in 2013. The American Psychiatric Association's summary of DSM-5 changes says a combined diagnosis "is now allowed".
How often do autism and ADHD occur together?
Often, though the figures vary a lot. A 2019 meta-analysis of 100 studies gave a pooled estimate of 28% for ADHD among autistic people. A 2022 review reports 50% to 70% in the literature, with single studies ranging from 10% to 90%.
Looking the other way, a meta-analysis of children and teenagers with ADHD found 21% met the threshold for autism. The spread reflects who was studied and how, but the overlap is common.
Is there an AuDHD test?
No single validated test exists. AuDHD isn't a diagnosis, so clinicians assess autism and ADHD separately, each against its own criteria.
There's no blood test or brain scan either. NICE, the health guidance body for England, advises against routine biological or genetic tests or brain imaging to diagnose autism.
What can an online neurodivergent test tell you?
Most online AuDHD tests and neurodivergent tests are quizzes. Even well-studied questionnaires are only a first filter. For adults with possible autism, NICE suggests a 10-question screener called the AQ-10. A score of 6 or more leads to an offer of a full assessment, not a diagnosis. For ADHD, NICE says a diagnosis shouldn't rest on rating scales alone.
A quiz can help you name patterns and gather examples to share. It can't tell you what's behind your answers. Anxiety or low mood can lead to similar answers. That's why NICE asks assessors to consider other explanations, such as anxiety or depression.
A quiz score is a prompt, not an answer. It can start a conversation with a professional. It can't confirm or rule out autism or ADHD.
How can autism and ADHD mask each other?
Autism and ADHD share some features, which can make them hard to tell apart. When both are present, each can hide or soften the other.
In a 2026 UK study, six women diagnosed with both as adults described this. Their traits sometimes seemed to "cancel each other out", and one or the other took the lead at different times. That made their path to diagnosis harder. Some doubted they were "autistic/ADHD enough". It was a small study, so treat it as insight rather than proof.
One label can also hold back the other. In a US study of children, those diagnosed with ADHD first got their autism diagnosis about three years later. Many autistic adults also mask, meaning they hide or compensate for autistic traits to fit in. Adults in one study of masking named exhaustion as a cost.
Routines versus novelty
A study of autistic online community posts included posts from AuDHD members. They described ADHD novelty-seeking clashing with an autistic need for routine. Routines could feel under-stimulating, which made tasks hard to start. Too little structure led to overwhelm and shutdown. One woman in the UK study said she was "forever starting routines and habits" but could "never stick to them".
Sensory needs
Sensory differences are part of autism. NICE lists over- and under-sensitivity to sensory input among the things an adult autism assessment should ask about. ADHD can pull the other way. One woman in the UK study said her autism alone would make her avoid some situations. "But my ADHD drives me to do these things and enjoy them," she wrote.
Executive dysfunction
Executive function covers skills such as planning, switching tasks, holding information in mind and holding back a response. When these feel hard, people often call it executive dysfunction. A review of 26 studies compared autistic, ADHD and combined groups. People with both shared planning and flexibility differences with autistic groups. They shared differences in holding back a response with ADHD groups.
Autistic burnout
Researchers working with autistic adults define autistic burnout as long-term exhaustion, typically lasting three months or more. It brings a loss of everyday skills and lower tolerance for stimulation. It's linked to chronic stress and a gap between expectations and the support available. Participants said acceptance, time off and unmasking helped recovery. The study suggests it's distinct from work burnout, which our guide to burnout therapy covers.
What does an adult assessment for autism and ADHD involve?
For autism, NICE guidance for adults says trained professionals should assess, ideally as a team. Where possible, a family member, partner or other informant takes part. Documents such as school reports can also help. Assessors ask about:
Traits over time: social communication, routines and interests, from childhood into adulthood.
Early development: your developmental history, where it's available.
Daily life: how things go at home, in study and at work.
Senses: over- or under-sensitivity to sound, light, touch and other input.
Other explanations: other neurodevelopmental differences, including ADHD, and mental health concerns.
An NHS autism assessment may include questionnaires and questions about your early life. The team may speak to someone who knew you as a child. Afterwards, you get a report on what they found.
For ADHD, NICE says a specialist psychiatrist or other qualified professional should make the diagnosis. It draws on a full clinical and psychosocial assessment, developmental history and observer reports. Under DSM-5, several ADHD traits must have been present before age 12. The NHS notes the specialist may contact a family member or close friend.
If you're exploring AuDHD, ask whether a service assesses both. NICE notes that ADHD is more common in autistic people. It also lists a history of ADHD as one reason to consider an autism assessment.
What to gather before an assessment
Examples: specific moments at home, study or work, from childhood and now.
Childhood records: school reports or teachers' comments, if you have them.
Someone who knew you young: a parent, sibling or older relative.
Quiz results: useful as notes, not as evidence.
Who assesses adults for autism and ADHD in Malaysia?
In Malaysia, psychiatrists and clinical psychologists carry out adult assessments for autism and ADHD. Our guide to counsellors, psychologists and psychiatrists explains the roles.
Psychiatrists: medical specialists in mental health. The Malaysian Medical Council says only doctors on its Specialist Register can practise in their specialty.
Clinical psychologists: registered under the Allied Health Professions Act 2016. The Malaysian Society of Clinical Psychology describes them as qualified to assess, diagnose and provide psychological therapy.
In the public system, the two work closely. In a 2015 sample of 2,179 referrals to Ministry of Health clinical psychologists, psychiatrists made 82.2%. For the public route, you might start by asking a klinik kesihatan doctor or GP about referral.
More Malaysian adults are seeking autism assessment, a KL consultant clinical psychologist told The Star in 2025. Before you book anywhere, you might ask:
Do you assess adults for both autism and ADHD, together or separately?
Who's involved, and what are their registration details?
Will you speak to a family member or look at school records?
What do I receive at the end, and what's the total cost?
How can Ripple help if you think you're AuDHD?
Ripple doesn't diagnose autism or ADHD. What it offers sits before, alongside or after an assessment.
Before you decide: the RM 50 Online Mental Health Screening is one hour online with a psychologist. You get a recommendation on whether further assessment or support may help. It isn't therapy or a diagnosis, and there's no written report.
Alongside or after: adult therapy with a team that works with neurodiversity. Sessions can focus on what matters to you, such as burnout, routines or relationships.
You don't need a diagnosis, a referral or a prior screening to start therapy. Sessions are 1 hour (the first is 1.5 hours), online or in person in Petaling Jaya. They run in English, Bahasa Malaysia and Mandarin. The first session is RM 200 with a counsellor or RM 300 with a clinical psychologist. Later sessions are RM 150 or RM 250.
Not sure where to start?
If much of this sounds familiar, that's worth taking seriously. A one-hour screening can help you decide whether a full assessment, therapy or both makes sense.

Frequently asked questions
Is Ripple's RM 50 screening an AuDHD test?
No. It's a private conversation with a psychologist about what's been happening for you. It ends with a suggested next step. That step might be a formal assessment elsewhere, therapy, or both.
Is it too late to get assessed as an adult?
No. NICE has guidance written specifically for autism in adults. Its ADHD guidance says to consider ADHD in all age groups. The women in the UK study above were all diagnosed as adults.
What if an assessment finds only autism or only ADHD?
That's still a useful answer. It explains part of your experience and can shape the support you choose. The NHS says an assessment report should also note anything else the team finds. You can ask what might explain the rest.
